DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] In order to make the above objectives, features and advantages of the present disclosure more clearly understood, the technical solutions of the present disclosure are further described below. It should be explained that, unless contradictory, the embodiments and features in the embodiments of the present disclosure can be combined with each other.

[0015] In order to fully understand the present disclosure, numerous details are specifically set forth in the following description; however, the present disclosure may be embodied in forms different from those described herein, and it is to be understood that the embodiments in the specification are merely some embodiments of the present disclosure, and not all embodiments.

[0016] The inventors of the present disclosure have found that in the prior art, the method by which a producer creates a material packet is cumbersome; for example, to obtain a material packet, a producer must first create an effects video and then cut out materials from the effects video.

[0017] In light of this, the present disclosure provides a material packet generation method to simplify the material packet creation process.

[0018] FIG. 1 is a schematic flow chart of a method for generating a content packet according to an embodiment of the present disclosure. This method may be applied to a first client realized by, for example, a mobile phone or a computer. The embodiment of the present disclosure does not limit the implementation form of the first client. A creating user (e.g., a creator of a content packet) may generate a content packet using the first client. As shown in FIG. 1, this method mainly includes the following steps S102 to S106.

[0019] Step S102: obtain an edit record file of a target video. The target video is a video obtained by synthesizing a specified material with an initial video through an editing operation.

[0020] In some embodiments, in response to receiving a content packet generation command initiated by a user, an edit record file of the target video may be obtained. Here, the target video is a video obtained by synthesizing a specified material with an initial video through an editing operation. In other words, the target video may be a video obtained by editing an initial video by adopting a specified material of a content packet to be created by a user (a creator of the content packet). The target video may be called an example video of the content packet.

[0021] In some embodiments of the present disclosure, the editing record file includes editing record information for recording editing operations, and the initial video and designated materials. For example, in the video editing software of the embodiments of the present disclosure, the editing process in which a user creates a video may be completely recorded to form an editing record file by obtaining a clip operation sequence for the initial video, materials used in each clip operation in the clip operation sequence, and a specific usage method of the materials in the initial video. For example, the editing record file is a protocol used by the video editing software to record the video editing state, which may store all information in the process in which a user edits a video, such as elements added by the user during video editing, parameters adjusted, and user operations. When a user opens a video again, the previous editing state can be restored by automatically reading the editing record file corresponding to this video.

[0022] In the embodiment of the present disclosure, the creator of the material packet does not need to cut out the material from the video, but can directly obtain the editing record file of the video and generate the material packet according to the editing record file.

[0023] Step S104: obtain a target material and application information of the target material according to the edit record file, where the application information includes edit record information of the target material in the target video.

[0024] Here, the target material belongs to the specified material. In some implementation examples, all materials in the specified material may be the target material. Since the creator of the material packet may not want to pack and share all the materials, only some materials selected by the creator of the material packet from the specified material may be the target material. The target material may be determined according to the needs of the user, and is not limited here. The application information of the target material can be directly extracted from the edit record file, which is known. The application information includes edit record information in the target video of the target material. The edit record information may include, for example, one or more of position information, rotation information, zoom information, and track information. In addition, the application information may further include an acquisition path of the target material. This acquisition path is used to indicate the manner of acquiring the material. For example, when the material is uploaded from a local area, the acquisition path of the material may be a file acquisition path, and when the material is downloaded from a network, the acquisition path of the material may be a network acquisition path.

[0025] In addition, the material in the embodiment of the present disclosure includes, but is not limited to, one or more of video, image, sticker, text, music, special effects, and filters. The editing record information may include, for example, one or more of position information, zoom information, and track information in the video of the material, and may be determined specifically based on the type of material. For example, when the material is a video, image, sticker, or text, the corresponding application information may include position information, zoom information, and track information; and when the material is an image, sticker, and text, it may further include rotation information; and when the material is music or special effects, the corresponding application information may include track information. The above is merely an example and should not be considered as a limitation.

[0026] Step S106: Generate a content packet for video editing based on the target material and its application information. After the target material and its application information are known, the first client may automatically pack the target material and its application information to generate a content packet for video editing. The generated content packet may then be sent to a server, which may distribute the content packet on a designated platform. The content packet may be shared through the designated platform, and other users may download and use the content packet from the designated platform.

[0027] In summary, an embodiment of the present disclosure provides a method for generating a material packet applied to a first client, the method including: acquiring an editing record file of a target video, the target video being a video obtained by synthesizing a designated material with an initial video through an editing operation, the editing record file including editing record information for recording the editing operation, the initial video, and the designated material; acquiring a target material and application information of the target material based on the editing record file, the application information including editing record information of the target material in the target video, and the target material belonging to the designated material; and generating a material packet for video editing based on the target material and its application information. It is no longer necessary for a creator of a material packet to cut out materials one by one from a video to create a material packet, and the material packet can be generated directly based on the target material and application information in the video editing record file, simplifying the process of creating the material packet.

[0028] In some embodiments, the step of obtaining the target material and application information of the target material based on the edit record file may include the following two main steps (1) and (2).

[0029] Step (1): all of the designated materials are selected as target materials, or the materials with a distribution permission identifier in the target materials are selected as target materials. That is, in practical applications, the following two examples may be referred to for implementation.

[0030] In the first embodiment, all materials in the specified materials are set as target materials. If no specification is made, all specified materials may be set as target materials by default.

[0031] In the second embodiment, the target material is a material with a distribution permission identifier. In practical application, a material checkbox may be provided to the creator. The creator may check the designated material used to create the target video, and the distribution permission identifier may be assigned to the checked designated material. In this manner, the creator's needs are fully considered, and only the material permitted by the creator is distributed, and some private materials that the creator does not want to use widely may not be distributed.

[0032] According to the actual situation, the above embodiment 1 and / or embodiment 2 may be flexibly selected and realized. The user may be provided with an option to "distribute all materials" or "distribute only some materials". When the user selects "distribute all materials", the above embodiment 1 may be adopted and when the user selects the option to "distribute only some materials", the above embodiment 2 may be adopted and realized. In particular, when the target materials include the creator's local materials, the user (the creator of the material packet) can assign a distribution permission identifier to the specified materials that he / she wants to distribute by checking the material checkbox, and only the materials that the user wants to upload can be packed while fully respecting the user's intention. Here, the local materials are materials that the user uploads through the first client, such as images that the creator uploads from a local album, or materials such as stickers and videos that the creator uploads from a local folder. In other words, the local materials are materials that are not publicly downloadable on the network, but are stored locally in the terminal. The creator can specify the materials that can be packed in the material packet according to demand, which is more flexible.

[0033] Step (2): the editing record information of the target video of the target material recorded in the editing record file is the application information of the target material, where the editing record information includes one or more of position information, rotation information, zoom information, and track information. In practical application, the editing record information corresponding to different types of materials may be different, and each type of material may correspond to one or more types of editing record information, which is not limited here.

[0034] In order to fully and effectively save the memory of the material packet, the application information of the target material further includes the acquisition path of the target material. In addition, the target material may not be directly packed into the material packet, but the identifier and application information of the target material (including the acquisition path and editing record information of the target material) may be stored in the material packet, so that the user of the material packet can clearly know how to acquire the target material and how to use the target material.

[0035] In the process of creating a material packet, the creator of the material packet often uses personal original local materials, such as original images, stickers, music, short videos, etc., to provide other users with fresh materials. Therefore, the target material generally includes at least one type of local material. And in many cases, the creator of the material packet not only uses local materials, but also uses remote materials, that is, the created material packet not only includes the creator's local materials, but also includes remote materials (original remote materials) downloaded by the creator via a network, where the remote materials are stored in a server and publicly downloadable. The embodiment of the present disclosure can directly identify the type of material (local / remote) in the target material and perform corresponding processing. For example, in order to save the memory of the material packet, the local material may not be stored in the material packet, but may first be distributed in the server to make the local material into a new remote material, and then the material packet only needs to store the identifiers of the original remote material and the new remote material (local material) and application information including the material acquisition path and editing record information. Such a processing method requires a small capacity of the material packet, and is very easy to download and disseminate.

[0036] Based on the above, an embodiment of the present disclosure provides a specific embodiment for generating a material packet for video editing based on a target material and its application information, and specifically, may be realized by referring to the following steps A to C.

[0037] Step A, upload local material in the target material to a server, and convert the local material into new remote material at the server, where the remote material is material stored on the server and publicly available for download.

[0038] In practical application, the local material in the target material can be automatically uploaded to a designated server, and then the server can distribute the local material on a designated platform, and the distributed local material becomes a new remote material. The storage and distribution of the material can be performed by the same server or different servers. For example, the local material is uploaded to a storage server, and the storage server stores the local material, and then the local material is sent to a material server, and the material server distributes the local material on a designated platform.

[0039] Step B: Receive a remote material identifier corresponding to the new remote material returned from the server, replace the acquisition path recorded in the application information of the local material with the remote material identifier of the new remote material, and make the replaced application information the application information corresponding to the new remote material.

[0040] When the server distributes the local material as a remote material, it newly assigns a corresponding material identifier to the remote material, and this material identifier may be a remote material identifier or a resource ID. The remote material identifier is an ID identifier of the remote material, and the remote material identifier corresponding to different remote materials is also different. As can be understood, for the producer of the material packet, the file acquisition path for the local material is recorded in the editing record file in order to produce the material packet using the material stored locally, but when distributing the local material to the public as a new remote material, when other users download the material packet, they only need to know the remote material identifier of the remote material in the material packet, and can download the corresponding remote material from the server by the remote material identifier. The above method allows other users to easily use the local material of the producer of the material packet.

[0041] It should also be noted that the editing record information in the application information is still kept intact, that is, for a local material in a target material, its corresponding application information includes the editing record information in the target video of the local material (abbreviated as material editing record information) and the file acquisition path of the local material, and when the local material is converted into a remote material by the server, the application information corresponding to the remote material includes the above-mentioned material editing record information and a remote material identifier corresponding to the remote material. In the embodiment of the present disclosure, the remote material identifier and the file acquisition path can both be used to indicate the specific acquisition method of the material, and both belong to the expression form of the acquisition path of the target material contained in the application information.

[0042] Step C: generating a content packet for video editing based on the new remote content and its application information and the original remote content and its application information in the target content, where the original remote content is content downloaded from the server by the first client in the process of generating the target video.

[0043] Since the local material of the creator is converted into remote material usable by others, a material packet for video editing can be directly generated based on the new remote material and its application information and the original remote material and its application information. As can be understood, the materials in the material packet obtained by the above method are all remote materials, some of which are new remote materials created by the creator distributing the local material through a server, and some of which are the original remote materials downloaded by the creator via a network.

[0044] In the above method, the local material and application information are directly obtained based on the editing record file, and the local material is distributed as a new remote material, the acquisition path in the application information of the local material is replaced with the remote material identifier, other contents of the application information may be kept as they are, and finally a material packet is generated based on the new remote material and its application information. For the creator of the material packet, it is no longer necessary to cut out the material from the video one by one to create the material packet, the process of creating the material packet is simplified, and there is no need to store the material in the material packet, only the acquisition path of the material and the editing record information need to be stored, so the required memory is small and it is easy to download and distribute.

[0045] In view of the above, the embodiment of the present disclosure may be considered as redefining a protocol of a material packet that clearly indicates the application method of the material. In other words, the material packet protocol may be understood as an aggregate content of the above-mentioned material application information, and the material packet according to the embodiment of the present disclosure includes a material set and a material packet protocol (i.e., material application information). Referring to the schematic diagram of the material packet protocol shown in FIG. 2, the application information corresponding to a plurality of types of materials that may be included in the material packet is shown in a schematic manner. FIG. 2 shows briefly the material types such as video, image, sticker, text, music, special effects, etc., and the application information corresponding to various material types. Here, the file path is the above-mentioned local material acquisition path, the resource ID is the above-mentioned remote material identifier, and both the file path / resource ID indicate the material acquisition method. It should be noted that FIG. 2 is merely a simple example and should not be considered as a limitation, and in actual applications, the material may further include, for example, filters, sound effects, etc., without being limited thereto. And the elements listed in FIG. 2 are all selective and combinable, and are not necessarily provided at the same time, and may be specifically customized according to actual needs and specific video editing software. In short, the material packet needs to record all the information of the material so that the effect of each material can be fully restored in subsequent applications. In addition, the material packet listed in FIG. 2 is the producer's first material packet, which has not yet been distributed, and the file path of the local material has not yet been replaced, so some materials may correspond to file paths (i.e., local materials). Once the local material is distributed, its corresponding file path is replaced with the remote material identifier of the corresponding remote material, and all the materials included in the finally formed material packet correspond to resource IDs, not file paths. In practical application, compared with the conventional material packet being only a material set, the material packet according to the embodiment of the present disclosure includes the material set and further includes the above material packet protocol, i.e., includes materials and corresponding application information.The application information indicates how the material is used and the method of obtaining the material, so that a user who downloads a material packet can clearly know how each material is applied in the video and can fully restore the effect of the producer of the material packet using the material in the video.

[0046] In some embodiments, in order to further improve the efficiency of generating the material packet and the convenience of using it, the original editing record file may be kept unchanged and a copy may be made of the editing record file. Then, the copy may be directly processed to obtain the material packet, that is, the editing record file may be modified into the material packet, so that the user who downloads the material packet can directly apply this material packet (modified editing record file). Specifically, the user who downloads the material packet does not need to add each material in the material packet to the video one by one, and after downloading this material packet, the user can directly use the material packet as an editing record file in the video that needs to be edited, and the specific manner in which the producer uses the material in the video (e.g., position, rotation, zoom, track, etc.) can be completely restored. Based on this, the above steps of replacing the acquisition path recorded in the application information of the local material with the remote material identifier of the new remote material and making the replaced application information the application information corresponding to the new remote material may be performed with reference to the following steps a to b.

[0047] Step a, duplicating the editing record file to obtain a copy of the editing record file.

[0048] Step b: process the copy so as to delete the local material contained in the copy, and replace the acquisition path recorded in the application information of the local material with the remote material identifier of the new remote material, and make the replaced application information the application information corresponding to the new remote material recorded in the copy. In some specific embodiments, the local material and related information may be deleted, and the acquisition path corresponding to the local material may be replaced with the remote material identifier according to the mapping relationship, or the other may be retained. With this simple and clever method, the existing editing record file can be directly converted into an applicable material packet without rewriting the application logic.

[0049] In the above, the step of generating a content packet for video editing based on the new remote material and its application information includes generating a content packet for video editing based on the processed copy, where the processed copy includes a remote material identifier of the new remote material and corresponding application information. Exemplarily, this may be realized by referring to the following steps (1) to (3).

[0050] Step (1): obtain a cover image of a specified material packet, and upload the cover image of the material packet to a server. The cover image of the material packet may be specified by the creator, and if not specified, a default cover image of the material packet may be selected and used.

[0051] Step (2): obtaining preset optional information of a material packet, where the optional information of the material packet includes one or more of the following: a target video, material version information, and material compatibility information. The target video is an exemplary video obtained by editing a plurality of materials, and whether to include the target video in the material packet may be determined according to actual needs. In some embodiments, the target video may be included in the material packet. In other embodiments, the target video may not be included in the material packet, and the target video may be a material independent of the material packet and associated with the material packet, thereby making the capacity of the material packet as small as possible. Other users may download only the material packet, and when they need to view the use example of the material packet, they download the target video associated therewith or view it online. The above material version information and material compatibility information may both be regarded as belonging to the extra.json extension file, and are used to record some special logic for processing the material packet, such as the specific application manner of the material packet in different terminals. For example, the size of a material that can be used normally on iOS® is 200*200, while the size that can be used normally on Android® is 300*300.

[0052] Step (3): The cover image of the content packet, the processed copy, and the option information of the obtained content packet are packed and compressed to obtain a compressed packet, which is used as a content packet for video editing. For example, the cover image of the content packet, the processed copy, and the option information of the obtained content packet may be packed to generate a Zip packet, which is then distributed to a background server, thereby realizing distribution and delivery of the content packet.

[0053] Further, the embodiments of the present disclosure provide a technical implementation of replacing the acquisition path recorded in the application information of the local material with the remote material identifier of the new remote material, including deleting the acquisition path recorded in the application information of the local material, and changing the local material identifier field in the application information of the local material to the remote material identifier of the new remote material. In some embodiments of the present disclosure, in order to identify the download origin of each remote material, the remote material in the target material is provided with a material source identifier for indicating the material storage location of the remote material. The material source identifier may be used to distinguish the platform that downloads the remote material. After the local material in the target material is converted into the new remote material by the server, the remote material identifier of the new remote material may be obtained by the server. In practical application, the target platform that downloads this remote material may be determined based on the material source identifier, and the corresponding remote material is downloaded from the target platform based on the remote material identifier. That is, an additional field for identifying the download origin may be added to each remote material in the material packet. For example, the material source identifier field is set as source_plaform, and the value of source_plaform may be, for example, 0, 1, 2, 3, 4, etc., and different values ​​represent different download platforms. In practical applications, there may be multiple platforms (or servers) used for downloading materials, and this value may be the identifier of the material download platform. For ease of understanding, the following provides an example description of changing the identifier field of the target local material to the remote material identifier (remote_id) and the newly added material source identifier (source_platform).

[0054] 1) video material: use remote_id to replace the material_id in the original materials.videos and add source_platform=1.

[0055] 2) audio materials: use remote_id to replace the music_id in the original materials.audios and add source_platform=2.

[0056] 3) image materials: use remote_id to replace the image_id in the original materials.image and add source_platform=1.

[0057] 4) sticker material: use remote_id to replace sticker_id in the original materials.image and add source_platform=1.

[0058] 5) text material: First, delete the text segment, then add a new character template segment with source_platform=1.

[0059] The above is merely an illustrative description and should not be considered as a limitation. In the application process of the material packet, the material acquisition platform can be determined according to the source_platform, and the corresponding remote material can be downloaded from the platform for acquiring the material according to the remote_id, so as to obtain all the materials in the material packet, and the material packet can be directly applied according to the material packet protocol.

[0060] As mentioned above, the embodiment of the present disclosure provides an example of converting an edit record file that a producer already has into a new material packet for distribution. Referring to the flow chart of material packet generation shown in FIG. 3, a specific manner of converting an edit record file into a material packet is outlined, and the execution body of each part is clearly indicated. As shown in this figure, the terminal can obtain the local material, the original remote material, and the material packet video, cover image, etc. adopted by the producer in the video editing based on the analysis of the edit record file, the local material is distributed by the server as a remote material, and the draft protocol is modified (made into an edit record file) after obtaining the remote material identifier fed back from the server, and the specific modification manner is as described above, modifying the acquisition path of the local material to the remote material identifier corresponding to the remote material obtained by distribution, uploading the material packet video, cover image, etc. to the server, and then packing it with the original remote material and the modified draft protocol to obtain a new material packet, and finally distributing the new material packet by the server. It should be noted that the main point of FIG. 3 is that different types of materials (local materials, remote materials, material packet videos or cover images) are processed differently in the process of generating material packets. For example, the local materials need to be distributed as remote materials by the server, and the protocol for the local materials needs to be modified (the acquisition path of the local materials in the editing record file is modified to the remote material identifier), the original remote materials can directly participate in packing without any other processing, and the material packet videos and cover images are uploaded and stored in the server before participating in packing. In actual applications, the above three types of materials are not necessarily all included. For example, some producers only use local materials (such as local videos, local music, local stickers, text, etc.) to edit videos, so the material packets do not have the original remote materials (such as stickers, special effects, filters, text templates, music, sound effects, etc.).Some producers may decide not to pack content packets into content packets, so there may be no content packets video, etc. In any case, however, to the creation of the content packets by the producer, the content packets are associated with local content.

[0061] Further, in accordance with the above, an embodiment of the present disclosure provides a schematic flow chart of local material processing shown in FIG. 4, which shows a schematic flow of distributing local material as new remote material. As shown in FIG. 4, the editing record file includes local material (local images, local audio) and original remote material (remote stickers, special effects, etc.). The local material may be uploaded to a storage server and distributed to the material server so that it can be used by the general public. For example, after uploading the local material to the storage server, the corresponding URL and KEY may be determined, and the local material may be distributed to the material server based on the URL and KEY to form the remote material. Once distributed by the server, the server's remote material identifier (remote_id) can be obtained, and the remote material is used to replace the local material, so that the generated material packet contains whatever is remote material. Specifically, the original local image is replaced with the remote image, and the local audio is replaced with the remote music. FIG. 4 also shows that a material origin identifier (source_platform) for identifying the source of the material can be newly added to the new remote material.

[0062] In some embodiments, the method further includes, in response to receiving the content packet title information and the content packet summary information, associating the content packet title information and the content packet summary information with the content packet.

[0063] In practical application, a content packet title box and a content packet summary box may be provided in the interface of a user terminal, so that the creator of the content packet can input the title of the content packet he / she created in the content packet title box, and input the theme description of the content packet in the content packet summary box, etc., so that other users who download the content packet can know the theme style of the content packet more clearly, and can quickly determine whether or not they need to download this content packet according to their needs.

[0064] In summary, the method for generating content packets according to the embodiment of the present disclosure eliminates the need for a content packet creator to cut out content from a video one by one to generate content packets, simplifying the content packet generation process and improving the efficiency of generating content packets. For a user of the content packets, the content packets are easier to use because they include application information for the material.

[0065] When a producer adopts materials to create an effect video (the aforementioned target video), the required target local materials can be determined according to demand, and the distribution of material packets can be realized by one key, which is very convenient and fast. The material packet not only records a material set, but also may include a material packet protocol. Specifically, the location information, zoom information, track information, and other usage record information of each material and the specific acquisition method of the material (for example, a remote material identifier) ​​are recorded. When other users apply with one key, they can automatically acquire the material based on the identifier, and directly restore the display effect in the video of each material based on the usage record information. And the material packet is directly obtained based on the editing record file, and other users can directly apply the material packet as a whole. Compared with the prior art, where the material packet only includes a material set, and the user of the material packet does not know how to specifically apply each material even after obtaining the material packet, and needs to repeatedly adjust it, the above method according to the embodiment of the present disclosure improves the usability of the material packet.

[0066] The inventors of the present disclosure further discovered that in conventional technology, the material packet created was merely a collection of individual materials, and even if other users obtained the material packet, they did not know how specifically to apply the materials contained therein, making the material packet extremely difficult to use.

[0067] In view of this, the embodiment of the present disclosure further provides a video editing method for improving the usability of material packets.

[0068] Based on the above-mentioned method for generating material packets, an embodiment of the present disclosure provides a video editing method. This method is applied to a second client. The second client may be realized by, for example, a mobile phone or a computer, and the embodiment of the present disclosure does not limit the realization form of the second client. A consumer user (e.g., a user of the material packets) can obtain the material packets using the second client and perform video editing using the material packets. As shown in FIG. 5, this method mainly includes the following steps S502 to S506.

[0069] Step S502, obtain a video to be edited. The video to be edited may be an original video to be edited uploaded by a user.

[0070] In step S504, in response to receiving the content packet application command, a specified content packet corresponding to the content packet application command is acquired. The specified content packet is generated by any one of the content packet generation methods described above in the embodiments of the present disclosure, and the description thereof will be omitted here.

[0071] In some specific implementation examples, in response to detecting a trigger operation of the material packet function, a plurality of target videos each corresponding to a material packet may be presented in the interface of the second client, and in response to detecting a selection operation of the target videos, it may be determined that a material packet application command has been received, and the material packet corresponding to the selected target video may be made a specified material packet corresponding to the material packet application command.

[0072] In practical application, the video editing software can provide a video editing function to a user, and present identifiers of multiple video editing functions in the interface of the second client. The video editing function includes a material packet function. When detecting that a user (a user of the material packet) clicks on an identifier or button of the material packet function, it may be deemed to detect a trigger operation of the material packet function, and further present multiple target videos in the interface of the second client. The target videos are videos generated and distributed by the producer of the material packet. The target videos are videos obtained by synthesizing the target materials with the initial video through an editing operation. Each target video corresponds to one material packet. As can be understood, the producer of one material packet can generate and distribute multiple material packets, and the various target videos that the video editing software presents in the interface of the second client may be generated and distributed by different producers of the material packet, and are not limited here. By presenting multiple target videos in the interface, the user of the material packet can intuitively feel the effect of applying the material packet to the video, and thereby select the required material packet. In the embodiment of the present disclosure, when it is detected that a user has clicked on a target video, it is deemed that the user requires a material packet corresponding to the target video, and therefore the material packet corresponding to the target video can be directly made into a specified material packet corresponding to a material packet application command, which is very convenient, quick and easy to implement.

[0073] In some embodiments, obtaining the specific content packet corresponding to the content packet application command includes sending an identifier of the specific content packet to a server, and downloading the specific content packet corresponding to the content packet application command by the server. In practical application, the actual content of the content packet may be stored on the server side, and when the specific content packet required by the user is determined, the second client may directly download the content of the specific content packet from the server, and the content packet may directly include the content and application information.

[0074] In step S506, editing is performed on the video to be edited based on the designated material packet.

[0075] In some embodiments, performing editing on the video to be edited based on the specified content packet includes compositing the material in the specified content packet into the video to be edited based on the application information of the material in the specified content packet. In practical application, the second client can automatically combine the material in the content packet into the video to be edited according to the application information based on the content contained in the specified content packet, so that the user of the content packet does not need to edit the video by adopting the material in the content packet point by point, and improves the usability of the content packet.

[0076] In summary, the embodiment of the present disclosure provides a video editing method applied to a second client, which includes: acquiring a video to be edited; acquiring a designated content packet corresponding to a content packet application command in response to receiving a content packet application command, the designated content packet being generated by the above-mentioned content packet generation method; and editing the video to be edited based on the designated content packet. According to the above video editing method, since the content packet has material application information attached thereto, users of the content packet can directly perform video editing based on the content packet. This makes it easier to use the content packet.

[0077] For ease of understanding, after obtaining the specified material packet, the embodiment of the present disclosure further provides a flow chart diagram of the material packet application shown in FIG. 6, which shows a specific application process after other users download the specified material packet. In addition to FIG. 4, FIG. 6 shows that the restoration of the edit record file can be realized by making a request to the material server based on the image remote_id and music remote_id to download and obtain the remote image and remote music. It should be noted that FIG. 6 is only an exemplary explanation, and the main point is to show the restoration flow of the local image / local audio delivered as a new remote material in the material packet use process, so the application process of the original remote material (e.g. remote sticker, special effect) and other materials is not shown. In actual situations, the original remote material of the material packet also needs to be requested to the material server by the corresponding remote_id to download the specific remote material. In addition, the editing record file in Figure 6 records "local images" and "local audio," which mainly indicates that these are essentially local images / audio provided by the producer, but for a user downloading a material packet, all of the materials in the resulting material packet (which is essentially an editing record file) are remote materials.

[0078] As shown in Figure 6, the material packet obtained by the user who downloads the material packet is essentially an edit record file, and as shown in Figures 3 and 4, the local material is replaced with the remote material and the identifier field of the edit record file is replaced with the remote material identifier, and the format of the edit record file is not changed essentially, so the format of the edit record file restored from the material packet is the same as that of the original edit record file, and can be applied with one key to directly restore the effect of each material in the target video in the video that the user who downloads the material packet wants to edit. In this way, it is easier for users to use the material packet to edit videos.

[0079] Corresponding to the above-mentioned content packet generating method, the embodiment of the present disclosure provides a content packet generating device applicable to a first client. Referring to the structural schematic diagram of the content packet generating device shown in Figure 7, the device mainly includes a file acquisition module 702, an information acquisition module 704, and a content packet generating module 706.

[0090] In some embodiments, the material packet generation module 706 is specifically used to delete the acquisition path recorded in the application information of the local material, and to change the local material identifier field in the application information of the local material to the remote material identifier of the new remote material.
