[0069] Exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings.

On the contrary, these embodiments are provided so that the present application can be more thoroughly understood and the scope of the present application can be fully conveyed to those skilled in the art.

[0070] Figure 1 A schematic diagram of an operating environment provided to implement at least one embodiment of the present application is shown. The present application can be applied to an application environment including, but not limited to, a client 2, a server 4, and a cloud storage end 6. Among them:

[0071] The client 2 can be an electronic device running operating systems such as Windows, Android TM ) or IOS, such as a smart phone, a tablet device, a laptop computer, a virtual reality device, a gaming device, a set-top box, a vehicle-mounted terminal, a smart TV.

[0072] The server 4 can be composed of a single or multiple computing devices. The multiple computing devices can include virtualized computing instances. The virtualized computing instances can include virtual machines, such as emulations of computer systems, operating systems, servers, etc. The computing devices can load virtual machines based on virtual images and / or other data that define specific software (e.g., operating systems, dedicated application programs, servers) for emulation. As the demand for different types of processing services changes, different virtual machines can be loaded and / or terminated on one or more computing devices. A hypervisor can be implemented to manage the use of different virtual machines on the same computing device.

[0073] The server 4 can be configured to communicate with the client 2, etc. via a network.

[0075] In some cases, the server 4 and the cloud storage end 6 can be set independently, and in other cases, the server 4 and the cloud storage end 6 can be integrated into one body.

[0076] Embodiment 1

[0077] Figure 2 The flowchart of a method for processing a clip draft provided in Embodiment 1 of the present application is shown. Among them, the method for processing a clip draft provided in this embodiment can be executed on the client side.

[0078] Specifically, as Figure 2 shown, the method includes the following steps:

[0079] Step S201, detecting a cloud storage operation for a target clip draft, and extracting clip operation data and at least one media resource from the target clip draft.

[0080] The client provides the user with a cloud storage function for clip drafts. The user can initiate a cloud storage operation for one or more clip drafts through corresponding trigger operations (such as click operations, preset shortcut key operations, voice control operations, etc.). The clip draft targeted by this cloud storage operation is the target clip draft.

[0081] Different from the prior art, after detecting a cloud storage operation for a target clip draft, the embodiment of the present application does not directly transmit the entire target clip draft to the cloud storage end for storage, but splits the target clip draft to extract clip operation data and media resources from the target clip draft. Among them, the clip operation data is the detailed information of each clip operation executed by the user during the process of processing the target clip draft on the client, such as the operation information of the clip operation, the clip operation object, the clip operation time, the resource identifier after the clip operation, etc. The media resources are pictures, audio, video, text, etc. in the target clip draft. The extracted media resources can be one or more.

[0082] Step S202, for any media resource, determining the original resource and the resource processing link of the media resource according to the clip operation data.

[0083] For each extracted media resource, determine the original resource on which the media resource depends according to the clip operation data. The original resource is the source resource of the media resource. The user can perform a series of clip operations on the original resource or obtain the media resource without performing clip operations. Among them, the clip operations include: adding filters, adding transitions, adding special effects, etc.

[0084] And, extract each clip operation from the original resource of the media resource to the generation of the media resource from the clip operation data, so as to obtain the resource processing link of the media resource. The resource processing link contains the sequence of clip operations experienced from the original resource to the media resource.

[0085] Among them, if the clip operation data does not contain the clip operation of the media resource, the original resource of the media resource is itself, and the resource processing link of the media resource is empty.

[0086] In an alternative embodiment, since the clip operation data contains the object information of each clip operation, the object information after clipping, and the operation information of the clip operation, the resource processing link of the media resource can be deduced backward from the clip operation data to obtain the resource processing link of the media resource. The starting node of the resource processing link can be used as that of the media resource.

[0087] Further optionally, a clip operation directed graph can be generated according to the clip operation data. Each node in the directed graph represents a resource (which can be represented by a resource identifier), and the directed edge between nodes represents the corresponding clip operation. Thus, the resource processing link of the media resource is extracted from the directed graph according to the resource identifier of the media resource, improving the processing accuracy of the resource processing link.

[0088] Further optionally, after determining the resource processing link of the media resource according to the clip operation data, if the resource processing link does not contain a splitting operation (such as a segmentation operation, a cropping operation, etc.), the resource corresponding to the starting node of the resource processing link is used as the original resource; if the resource processing link contains a splitting operation, the splitting operation is removed from the resource processing link, and the splitting operation is performed on the starting resource corresponding to the resource processing link, and the resource after the starting resource performs the splitting operation is used as the original resource of the media resource, thereby reducing the resource data volume of the original resource and saving transmission and storage resources on the premise of ensuring the accuracy of the processing result. For example, if the original resource processing link is "resource S1 → add filter A → add special effect B → media resource S2", and this resource processing link does not contain a splitting operation, the starting resource S1 is used as the original resource of the media resource S2; if the original resource processing link is "resource S1 → add filter A → add special effect B → crop → media resource S2", and this resource processing link contains the splitting operation of cropping, the cropping operation is removed from the resource processing link, and the cropping operation is performed on the starting resource "resource S1" corresponding to the resource processing link to obtain "resource S1_1 after performing the cropping operation", and the "resource S1_1 after performing the cropping operation" is used as the original resource of the media resource S2, so that the corrected resource processing link is "resource S1_1 after performing the cropping operation → add filter A → add special effect B → media resource S2".

[0089] Step S203: Provide the resource processing link of the media resource, the resource characteristics of the original resource, and the clip operation data to the server. For any media resource, when the server determines that the original resource corresponding to the media resource is stored in the cloud storage based on the resource characteristics of the original resource of the media resource, generate the cloud storage data of the media resource according to the storage identifier of the original resource in the cloud storage and the resource processing link of the media resource; and generate the cloud draft of the target clip draft according to the clip operation data and the cloud storage data of each media resource, and store the cloud draft in the cloud storage.

[0090] For a media resource, extract the resource characteristics of the original resource of the media resource. The resource characteristics are identification information that can uniquely identify the media resource, such as hash value, digital fingerprint, etc. Provide the resource characteristics of the original resource of the media resource and the resource processing link of the media resource to the server. Also provide the clip operation data of the extracted target clip draft to the server.

[0091] The server receives the data provided by the client. For any media resource provided with resource characteristics, search in the cloud storage based on the resource characteristics of the original resource of the media resource to check if there is a resource that matches the resource characteristics. If it exists, it is determined that the original resource of the media resource is already stored in the cloud storage, and then obtain the storage identifier (such as resource identifier, storage path, etc.) of the original resource in the cloud storage, and generate storage data according to the storage identifier of the original resource of the media resource and the resource processing link. This storage data is called cloud storage data.

[0092] The server generates the cloud draft corresponding to the target clip draft according to the cloud storage data and clip operation data of all media resources of the target clip draft, and then stores the cloud draft in the cloud storage to achieve the cloud storage of the target clip draft.

[0093] It can be seen from this that in the case where the original resource is already stored in the cloud storage in this application, only the storage identifier and resource processing link of the original resource of the media resource are stored, so that the original resource itself will not be stored repeatedly, greatly saving cloud storage resources.

[0094] In an optional implementation manner, the client will open a corresponding material library for the user, and the user can select materials from the material library to participate in the clip process. Thus, in this implementation manner, according to the different resource types of the original resources, a matching method is used to extract the data that needs to be uploaded to the server. For any media resource, the data that the media resource needs to upload to the server can be determined by the Figure 3 steps shown:

[0095] S2031, Determine whether the original resource of the media resource is a material in the preset material library; if so, execute step S2032; if not, execute step S2033.

[0096] According to the resource attributes of the original resource, it can be determined whether the original resource is a material in the preset material library, and corresponding processing steps are executed according to different judgment results.

[0097] S2032, Generate cloud storage data for the media resource according to the material identifier of the original resource and the resource processing link of the media resource, and provide the cloud storage data of the media resource to the server.

[0098] If the original resource of the media resource is a material in the preset material library, and the materials in the preset material library can be directly obtained from the preset material library, so in this embodiment, only the material identifier of the original resource is obtained, and through this material identifier, it can be determined which material in which material library the original resource corresponds to.

[0099] Furthermore, after combining the material identifier and the resource processing link, the cloud storage data of the media resource is obtained. Thus, the cloud storage data of this type of media resource is generated in the client and the generated cloud storage data is provided to the server.

[0100] S2033, Provide the resource processing link of the media resource and the resource characteristics of the original resource to the server.

[0101] If the original resource of the media resource is not a material in the preset material library, then provide the resource characteristics of the original resource and the resource processing link to the server.

[0102] Adopt Figure 3 The steps shown can further streamline the transmission volume from the client to the server, reduce the cloud storage pressure, and save cloud storage resources.

[0103] In an alternative embodiment, when the server determines that the original resource of a certain media resource is not stored in the cloud storage end according to the resource characteristics, it will send corresponding feedback information to the client. After the client receives the feedback information that the original resource of a certain media resource is not stored in the cloud storage end sent by the server, it provides the original resource to the server, and the server generates the cloud storage data of the media resource according to the original resource of the media resource and the resource processing link.

[0104] In an alternative implementation, after the cloud storage of the target clip draft is completed, the user can initiate a cloud download operation for the target clip draft. When the client detects the cloud download operation for the target clip draft, it sends a download request for the cloud draft of the target clip draft to the server. The server can authenticate the client's permissions. If the permission authentication is passed, the server enables the client to establish a communication connection with the cloud storage end, so as to download the target clip draft; alternatively, the server can provide the cloud draft to the client.

[0105] Further, the client obtains the cloud draft of the target clip draft and restores the target clip draft according to the cloud draft. Specifically, each cloud storage data in the cloud draft is extracted. For any cloud storage data, if the cloud storage data contains the original resource and the resource processing link, the original resource is executed according to the resource processing link to restore the corresponding media resource; if the cloud storage data contains the storage identifier of the original resource and the resource processing link, the corresponding original resource is downloaded from the cloud storage end according to the storage identifier, and the original resource is executed according to the resource processing link to restore the corresponding media resource; if the cloud storage data contains the material identifier and the resource processing link, the corresponding original resource is obtained from the preset material library according to the material identifier, and the original resource is executed according to the resource processing link to restore the corresponding media resource. Further, according to the editing operation data (including the combination method of each media resource, etc.) in the cloud draft, each media resource is merged to restore the target clip draft.

[0106] In an alternative implementation, to facilitate the management of the cloud draft (the cloud draft of the clip draft at the cloud storage end), this implementation provides a management entry for the cloud draft for the user in the client, and the specific management process can refer to Figure 4 .

[0107] As Figure 4 shown, the user enters the cloud space. When logged in currently, the cloud space list is displayed, and the cloud space list contains the detailed information of each cloud draft, such as the cloud draft upload time, editing time, creator, etc.

[0108] If the cloud space list is empty, the upload process can be entered: display the local draft list on the client side, and each clip draft stored locally is displayed in this local draft list. The user can select one or more local drafts through corresponding selection operations and click upload. When the server determines that a backup of this version already exists in the cloud, it prompts to overwrite or create a new draft; if there is no backup in the cloud, it performs a preset network connection check such as WiFi. If there is a preset network connection currently, it calls the plugin to upload. If there is no preset network connection currently, it prompts whether to continue uploading. After calling the plugin to upload, the local draft list can be synchronously closed for splitting processing. Perform file occupancy analysis. If it is determined that the current cloud space has exceeded the preset limit, indicating that the cloud space is full, it prompts that the task fails. If the cloud space is not full, it executes the upload step and displays a prompt message indicating successful upload after the upload.

[0109] If the cloud space list is not empty, the user can edit the existing cloud drafts, such as performing operations like renaming, deleting, downloading, etc. When downloading a cloud draft, after performing a network connection check, it is downloaded. And based on the data after downloading, the clip draft is restored and inserted into the local draft.

[0110] It can be seen that in the clip draft processing method provided by the embodiment of the present application, the client splits the target clip draft to be cloud - stored into clip operation data and media resources, and converts the media resources into the combination of the original resources and the resource processing link, which is convenient for subsequent streamlining of cloud drafts and saving cloud storage resources; moreover, when the server determines that the original resources have been stored in the cloud storage end according to the resource characteristics of the original resources, it only generates cloud storage data based on the storage identifier of the original resources of the media resources and the resource processing link, and then obtains the cloud draft of the target clip draft according to the cloud storage data of each media resource combined with the clip operation data, and then stores this cloud draft in the cloud storage end. The cloud draft has a significantly reduced data volume compared to the target clip draft, thus saving cloud storage resources. And, the target clip draft can be accurately restored according to the cloud draft, ensuring the storage accuracy of the clip draft.

[0111] Embodiment Two

[0112] Figure 5 The flowchart of a clip draft processing method provided by Embodiment Two of the present application is shown. Among them, the clip draft processing method provided in this embodiment can be executed on the server side.

[0113] Specifically, as Figure 5 shown, the method includes the following steps:

[0114] Step S501, receive the cloud storage request for the target clip draft sent by the client, extract the resource processing link of the media resources of the target clip draft, the resource characteristics of the original resources, and the clip operation data of the target clip draft from the cloud storage request.

[0115] The client detects a cloud storage operation by the user on the target clip draft, extracts clip operation data and at least one media resource from the target clip draft; and for any media resource, determines the original resource and the resource processing link of the media resource according to the clip operation data, and then provides the resource characteristics of the original resource of the media resource, the resource processing link, and the clip operation data to the server, and the server receives the data transmitted by the client.

[0116] Step S502, for any media resource, if it is determined according to the resource characteristics of the original resource of the media resource that the original resource is stored in the cloud storage end, then generate the cloud storage data of the media resource according to the storage identifier of the original resource in the cloud storage end and the resource processing link of the media resource.

[0117] The server searches for a resource that matches the resource characteristics of the original resource from the stored data in the cloud storage end according to the received resource characteristics of the original resource. If a resource that matches the resource characteristics can be found in the cloud storage end, it indicates that the original resource has been stored in the cloud storage end, and then extracts the storage identifier of the original resource in the cloud storage end. This storage identifier is an identifier that can uniquely determine the resource in the cloud storage end, such as the unique ID assigned to the resource in the cloud storage end, or the storage path, etc. Then, for this media resource, generate the cloud storage data of the media resource according to the storage identifier of its original resource in the cloud storage end and the resource processing link of the media resource. Thus, the cloud storage data of this type of media resource neither contains the media resource itself nor the original resource itself, but only contains the storage identifier of the original resource and the resource processing link, thereby greatly reducing the storage overhead.

[0118] In an alternative embodiment, the server generates corresponding cloud storage data in a matching manner according to the different media resources. For any media resource, the process of generating its cloud storage data can refer to Figure 6 the steps shown below:

[0119] S5021, determine whether the client provides the cloud storage data of this media resource; if so, execute step S5022; if not, execute step S5023.

[0120] For a media resource whose original resource is a material in the preset material library, the client will generate the cloud storage data of the media resource according to the material identifier of the original resource and the resource processing link of the media resource, and provide the cloud storage data of the media resource to the server.

[0121] The server receives the cloud storage data of the media resource whose original resource is a material in the preset material library sent by the client. When determining the generation method of the cloud storage data of the current media resource, it is judged whether the cloud storage data of this media resource provided by the client has been received.

[0122] S5022, cache the cloud storage data of the media resource.

[0123] If the server has received the cloud storage data of the media resource provided by the client, the server caches the cloud storage data of the media resource and waits for the generation of the subsequent total cloud storage data.

[0124] S5023, determine whether the original resource of the media resource is stored in the cloud storage; if so, execute step S5024; if not, execute step S5025.

[0125] If the server has not received the cloud storage data of the media resource provided by the client currently, and what the server receives is the resource feature of the original resource of the media resource, then check whether there is a resource matching the resource feature in the cloud storage; if there is, it is determined that the original resource of the media resource is stored in the cloud storage; if not, it is determined that the original resource of the media resource is not stored in the cloud storage.

[0126] Among them, the resource feature includes a hash value and / or a digital fingerprint. In the specific implementation process, the hash value of the original resource can be used to determine whether the original resource of the media resource is stored in the cloud storage first. If there is, execute step S5024; if not, then obtain the digital fingerprint of the original resource to determine whether the original resource of the media resource is stored in the cloud storage. If there is, execute step S5024; if not, execute step S5035. Among them, the digital fingerprint can be provided by the client, or the client provides the original resource to the server, and the server extracts its digital fingerprint. By using the dual judgment method of hash value and digital fingerprint, the occurrence of misjudgment can be reduced and the draft storage accuracy can be improved.

[0127] S5024, generate the cloud storage data of the media resource according to the storage identifier of the original resource in the cloud storage and the resource processing link of the media resource.

[0128] If the original resource of the media resource is stored in the cloud storage, obtain the storage identifier of the original resource in the cloud storage, and merge the storage identifier with the resource processing link of the media resource to obtain the cloud storage data of the media resource.

[0129] S5025, send feedback information to the client that the original resource is not stored in the cloud storage, receive the original resource sent by the client, and generate the cloud storage data of the media resource according to the original resource of the media resource and the resource processing link.

[0130] If the original resource of the media resource is not stored in the cloud storage end, feedback information indicating that the original resource is not stored in the cloud storage end is sent to the client, and the client provides the original resource to the server based on this feedback information. The server combines the original resource of the media resource and the resource processing link to obtain the cloud storage data of the media resource.

[0131] Step S503: Generate a cloud draft of the target clip draft according to the clip operation data and the cloud storage data of each media resource, and store the cloud draft in the cloud storage end.

[0132] By implementing steps S501 and S502, the cloud storage data of each media resource of the target clip draft can be obtained. Then, the clip operation data of the target clip draft and the cloud storage data of each media resource are combined to generate a cloud draft of the target clip draft, and the cloud draft is stored in the cloud storage end.

[0133] In an optional implementation manner, when the cloud storage end stores the cloud draft of the target clip draft, specifically, the draft identifier of the target clip draft is associated and stored with the cloud draft. And for the original resource in the cloud draft, after storing the original resource, a corresponding storage identifier is assigned to it.

[0134] Moreover, the cloud storage end also generates and maintains a reference table of the storage identifier of the original resource and the clip draft identifier. The reference table records the resource reference information of each stored original resource, and the resource reference information is specifically the cloud draft identifier that references the original resource. For example, if a certain media resource in cloud draft S2 and cloud draft S3 both depends on the original resource Y, the cloud storage end stores the original resource Y and records in the reference table that the cloud drafts that reference the original resource Y are cloud draft S2 and cloud draft S3. Thus, for the original resource in the cloud draft, in addition to storing the original resource and assigning a storage identifier to it, the reference table is also updated to record the association relationship between the storage identifier of the newly stored original resource and the cloud draft identifier; for the storage identifier of the original resource included in the cloud draft, the reference table is updated to add the association relationship between the storage identifier of the original resource and the cloud draft identifier. Thus, through this reference table, it can be quickly and accurately determined which cloud drafts currently reference which original resources, facilitating the management of stored data. For example, when receiving a deletion operation of a certain cloud draft from the client, the storage identifiers of the original resources referenced by the cloud draft are determined through the reference table. If the storage identifier of the associated original resource is not associated with other cloud draft identifiers, the original resource is deleted; if the storage identifier of the associated original resource is associated with other cloud draft identifiers, the original resource is not deleted. In addition, other data in the cloud draft except for the original resource in the cloud draft is also deleted, and the reference table is updated to reflect the reference relationship between the cloud draft and the original resource.

[0135] In addition, the cloud storage side can deduplicate or merge the stored original resources based on the resource characteristics of the storage resources, thereby further saving storage space. After deduplication or merging, the reference table is updated synchronously.

[0136] In an alternative embodiment, since the cloud draft is stored in the cloud in the embodiments of the present application, multiple users with the operation permission for the same cloud draft, or different clients of the same user, can collaborate to process the cloud draft. In this case, in order to ensure the data accuracy of the cloud draft, the version number of the cloud draft is updated each time the cloud draft of the same clip draft is generated in this embodiment, and when the client downloads the target cloud draft, the latest target cloud draft on the server side and the cloud draft version number of the target cloud draft are provided to the client. When the client initiates a cloud storage request for the target clip draft, the version control can be specifically performed through Figure 7 the following steps:

[0137] S701, Receive a cloud storage request for the target clip draft sent by the client.

[0138] S702, Determine whether the cloud storage request carries a client cloud draft version number; if so, execute step S703; if not, execute step S709.

[0139] If the current target clip draft to be cloud-stored is modified based on an existing cloud draft, the cloud storage request will carry the version number of the cloud draft, and this version number is called the client cloud draft version number, then execute step S703 for version verification.

[0140] If the current target clip draft to be cloud-stored is not generated depending on a certain cloud draft, the client-initiated cloud storage request will not carry the client cloud draft version number, then execute step S709 to generate and store the corresponding cloud draft.

[0141] S703, Obtain the server-side cloud draft version number corresponding to the target clip draft.

[0142] If the cloud storage request carries a client cloud draft version number, determine the cloud draft of the target clip draft stored on the cloud storage side, and obtain the latest version number of the cloud draft on the cloud, and this version number is called the server-side cloud draft version number corresponding to the target clip draft.

[0143] S704, Compare the server-side cloud draft version number with the client cloud draft version number; if the server-side cloud draft version number is greater than the client cloud draft version number, execute S705; if the server-side cloud draft version number is equal to the client cloud draft version number, execute S709; if the server-side cloud draft version number is less than the client cloud draft version number, execute S710.

[0144] S705. Generate a new cloud draft of the target clip draft, determine the first modified track of the new cloud draft compared to the cloud draft corresponding to the client cloud draft version number, and determine the second modified track of the cloud draft corresponding to the server cloud draft version number compared to the cloud draft corresponding to the client cloud draft version number.

[0145] If the server cloud draft version number is greater than the client cloud draft version number, it indicates that during the modification process of the current client on the original cloud draft, other clients have updated the original cloud draft. In this case, generate the cloud draft of the current target clip draft. The newly generated cloud draft is called the new cloud draft. The generation process of this new cloud draft can refer to the implementation process of other steps, which will not be elaborated here.

[0146] Moreover, different clip tracks are divided according to different resource types, such as audio tracks, video tracks, subtitle tracks, etc. Further determine the first modified track of the new cloud draft compared to the cloud draft corresponding to the client cloud draft version number (referred to as the original cloud draft), that is, the modified track of the new cloud draft compared to the original cloud draft is called the first modified track. Specifically, by comparing the clip operation data in the new cloud draft and the clip operation data in the original cloud draft, it is possible to accurately determine what modifications the current client has made to the original cloud draft, and then determine the clip tracks corresponding to these modifications, and use the clip tracks corresponding to the modifications as the first modified track.

[0147] And determine the modified track of the cloud draft corresponding to the server cloud draft version number compared to the cloud draft corresponding to the client cloud draft version number. This modified track is called the second modified track. Specifically, by comparing the clip operation data in the cloud draft corresponding to the server cloud draft version number (referred to as the server cloud draft) and the clip operation data in the cloud draft corresponding to the client cloud draft version number (referred to as the original cloud draft), it is possible to accurately determine what modifications the server cloud draft has made on the basis of the original cloud draft, and then determine the clip tracks corresponding to these modifications, and use the clip tracks corresponding to the modifications as the second modified track.

[0148] S706. Determine whether there is an intersection between the first modified track and the second modified track; if so, execute S707; if not, execute S708.

[0149] If there is a same part between the first modified track and the second modified track, it is determined that there is an intersection; if there is no same part between the first modified track and the second modified track, it is determined that there is no intersection.

[0150] S707. Store the new cloud draft in the cloud storage and delete the cloud draft corresponding to the server cloud draft version number in the cloud storage.

[0151] If there is an intersection between the first modified track and the second modified track, for example, both the first modified track and the second modified track contain a video track. Then, overwrite and store the new cloud draft on the server cloud draft, that is, store the new cloud draft in the cloud storage, and delete the cloud draft corresponding to the server cloud draft version number in the cloud storage. When deleting, if the original resources in the server cloud draft are not referenced by the new cloud draft or other cloud drafts, delete the entire server cloud draft; if the original resources in the server cloud draft are referenced by the new cloud draft or other cloud drafts, retain the stored original resources, delete other data in the server cloud draft except the retained original resources, and update the reference table.

[0152] In the specific implementation process, if there is an intersection between the first modified track and the second modified track, it is also possible to feedback a prompt message for overwrite storage to the client. Under the condition that the client executes the confirmation operation for overwrite storage, then overwrite and store the new cloud draft on the server cloud draft.

[0153] Or, if there is an intersection between the first modified track and the second modified track, feedback a prompt message for re - creation to the client. Under the condition that the client executes the confirmation operation for re - creation, create a new cloud draft identifier for the new cloud draft and store it, while the original server cloud draft is retained. In this way, both the new cloud draft and the server cloud draft are retained, but they correspond to different cloud draft identifiers.

[0154] S708, merge and store the new cloud draft with the cloud draft corresponding to the server cloud draft version number in the cloud storage.

[0155] If there is no intersection between the first modified track and the second modified track, for example, the first modified track is an audio track and the second modified track is a video track. Then, merge the new cloud draft with the server cloud draft and then store it in the cloud storage. In this case, the new cloud draft and the server cloud draft are merged into one cloud draft for storage.

[0156] S709, generate a cloud draft of the target clip draft and store the cloud draft in the cloud storage.

[0157] If the server cloud draft version number is equal to the client cloud draft version number, or if the cloud storage request does not carry the client cloud draft version number, generate a cloud draft of the target clip draft and store the cloud draft in the cloud storage.

[0158] S710, generate an exception prompt message.

[0159] If the server cloud draft version number is less than the client cloud draft version number, it indicates that there is an exception currently, and thus generate a corresponding exception prompt message for the exception handling end to perform exception handling.

[0160] It can be seen that in the clip draft processing method provided by the embodiments of the present application, the client splits the target clip draft to be cloud-stored into clip operation data and media resources, and converts the media resources into a combination of original resources and resource processing links, which facilitates subsequent streamlining of cloud drafts and saves cloud storage resources. Moreover, when the server determines that the original resources are already stored in the cloud storage end according to the resource characteristics of the original resources, it generates cloud storage data only based on the storage identifiers of the original resources of the media resources and the resource processing links, and then obtains the cloud draft of the target clip draft according to the cloud storage data of each media resource combined with the clip operation data, and then stores the cloud draft in the cloud storage end. The cloud draft has a significantly reduced data volume compared to the target clip draft, thus saving cloud storage resources. And, the target clip draft can be accurately restored according to the cloud draft, ensuring the storage accuracy of the clip draft.

[0161] Embodiment III

[0162] Figure 8 The flowchart of a clip draft processing method provided by Embodiment III of the present application is shown. As Figure 8 shown, the method specifically includes the following steps:

[0163] Step S801, the client detects a cloud storage operation for the target clip draft, extracts clip operation data and at least one media resource from the target clip draft; for the media resource, determines the original resource and the resource processing link of the media resource according to the clip operation data.

[0164] After detecting a cloud storage operation for the target clip draft, the client splits the target clip draft into clip operation data and media resources. And converts the media resources into their dependent original resources and corresponding resource processing links.

[0165] Step S802, the client determines whether the original resource is a material; if so, executes step S803; if not, executes step S804.

[0166] Step S803, the client generates cloud storage data for the media resource according to the material identifier of the original resource and the resource processing link of the media resource, and provides the cloud storage data of the media resource to the server.

[0167] For the case where the original resource is a material in the preset material library, the client generates cloud storage data for the media resource according to the material identifier of the original resource in the preset material library and the resource processing link of the media resource, and synchronizes the cloud storage data to the server.

[0168] Step S804, the client provides the resource processing link of the media resource and the resource characteristics of the original resource to the server.

[0169] In the case where the original resource of the client is not the material in the preset material library, the resource processing link of the media resource and the resource characteristics of the original resource are provided to the server.

[0170] Step S805: The server determines whether the original resource is stored in the cloud storage according to the resource characteristics; if so, step S806 is executed; if not, step S807 is executed.

[0171] Step S806: The server generates the cloud storage data of the media resource according to the storage identifier of the original resource in the cloud storage and the resource processing link of the media resource.

[0172] If the server determines that the original resource is stored in the cloud storage, it generates the cloud storage data of the media resource according to the storage identifier of the original resource in the cloud storage and the resource processing link of the media resource.

[0173] Step S807: The server obtains the original resource and generates the cloud storage data of the media resource according to the original resource and the resource processing link of the media resource.

[0174] If the server determines that the original resource is not stored in the cloud storage, it obtains the original resource from the client and generates the cloud storage data of the media resource according to the original resource and the resource processing link of the media resource.

[0175] Step S808: The server generates the cloud draft of the target clip draft according to the clip operation data and the cloud storage data of each media resource.

[0176] Step S809: The server stores the cloud draft in the cloud storage.

[0177] It can be seen that in the clip draft processing method provided by the embodiment of the present application, the client splits the target clip draft to be cloud-stored into clip operation data and media resources, and converts the media resources into the combination of the original resources and the resource processing link, which is convenient for subsequent cloud draft simplification and saves cloud storage resources; moreover, in the case where the original resource is the material in the preset material library, the client generates the cloud storage data of the media resource according to the material identifier and the resource processing link; in the case where the original resource is not the material but has been stored in the cloud storage, the server generates the cloud storage data of the media resource according to the storage identifier of the original resource and the resource processing link; in the case where the original resource is not the material and has not been stored in the cloud storage, the server generates the cloud storage data of the media resource according to the original resource and the resource processing link; and then obtains the cloud draft of the target clip draft according to the cloud storage data of each media resource combined with the clip operation data, and then stores the cloud draft in the cloud storage. The cloud draft has a significantly reduced data volume compared with the target clip draft, thus saving cloud storage resources. And, the target clip draft can be accurately restored according to the cloud draft, ensuring the storage accuracy of the clip draft.

[0185] In an optional implementation manner, the sending module 930 is configured to: upon receiving feedback information sent by the server that the cloud storage end does not store the original resource, provide the original resource to the server for the server to generate cloud storage data of the media resource according to the original resource and the resource processing link of the media resource.

[0186] In an alternative embodiment, the device further includes: a download module (not shown in the figure), configured to send a download request for a target cloud draft to a server, and obtain the target cloud draft; and restore a corresponding clip draft according to the target cloud draft.

[0187] It can be seen that for the clip draft processing device provided in the embodiments of the present application, the client splits the target clip draft to be cloud stored into clip operation data and media resources, and converts the media resources into a combination of original resources and a resource processing link, which facilitates subsequent streamlining of the cloud draft and saves cloud storage resources; moreover, when the server determines that the original resources are already stored in the cloud storage end according to the resource characteristics of the original resources, it generates cloud storage data only based on the storage identifier of the original resources of the media resources and the resource processing link, and then obtains the cloud draft of the target clip draft according to the cloud storage data of each media resource in combination with the clip operation data, and then stores the cloud draft in the cloud storage end. The cloud draft has a significantly reduced data volume compared to the target clip draft, thus saving cloud storage resources. And, the target clip draft can be accurately restored according to the cloud draft, ensuring the storage accuracy of the clip draft.

As Figure 10 shown, the device 1000 includes: a receiving module 1010, a first generating module 1020, a second generating module 1030, and a storage module 1040.

[0190] The receiving module 1010 is configured to receive a cloud storage request for a target clip draft sent by a client, and extract the resource processing link of the media resources of the target clip draft, the resource characteristics of the original resources, and the clip operation data of the target clip draft from the cloud storage request;

[0191] The first generating module 1020 is configured to, for any media resource, if it is determined according to the resource characteristics of the original resources of the media resource that the original resource is stored in the cloud storage end, generate cloud storage data for the media resource according to the storage identifier of the original resource in the cloud storage end and the resource processing link of the media resource;

[0214] In summary, according to the system, computing device, computer storage medium, and computer program product provided in this embodiment, it can be seen that for the clip draft processing method provided in the embodiments of the present application, the client splits the target clip draft to be cloud-stored into clip operation data and media resources, and converts the media resources into a combination of original resources and resource processing links, which facilitates subsequent streamlining of cloud drafts and saves cloud storage resources; moreover, when the server determines that the original resources have been stored in the cloud storage end according to the resource characteristics of the original resources, it generates cloud storage data only based on the storage identifier of the original resources of the media resources and the resource processing links, and then obtains the cloud draft of the target clip draft according to the cloud storage data of each media resource combined with the clip operation data, and then stores the cloud draft in the cloud storage end. The cloud draft has a significantly reduced data volume compared to the target clip draft, thus saving cloud storage resources. And, the target clip draft can be accurately restored according to the cloud draft, ensuring the storage accuracy of the clip draft.
