[0020] The following will be combined with the accompanying drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of this application.

It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0022] The following is combined with Figures 1 to 8 , the video generation method, video generation device, electronic device and storage medium provided in the embodiments of the present application are described through specific embodiments and their application scenarios.

[0023] In some embodiments of the present application, a video generation method is provided. Figure 1 FIG. 1 shows a flow chart of a video generation method provided in an embodiment of the present application. Figure 1 As shown, the video generation method includes:

[0024] Step 102: During the video recording process, if the target object is included in the video recording interface, a video index is generated, where the video index is associated with the moment when the target object appears in the video.

[0025] The "entry point" is the moment in the video when the target object appears in the video preview interface during video recording. The video index is associated with the entry point, and during video playback, the video index can be used to locate the moment when the target object appears in the video playback screen.

[0026] Step 104: After recording is completed, a first video is obtained;

[0027] Step 106: Generate a target video based on the first video and the video index.

[0028] In an embodiment of the present application, the electronic device can, during the video recording process, generate a corresponding video index for the target object when it detects that the video recording interface includes a target object. The video index corresponds to the moment when the above-mentioned target object enters the frame, that is, the position of the video index can change with the change of the moment when the target object enters the frame. After the electronic device finishes the video recording, it can generate a target video with a video index based on the obtained first video and the video index.

[0029] While a user is recording a video using an electronic device, the electronic device continuously detects the displayed content in the video recording interface, which is related to the subject being recorded. Upon detecting that the video recording interface includes a target subject, the electronic device generates a video index, with the playback time corresponding to the video index being the moment the target subject enters the frame. After recording a first video, the electronic device can obtain the first video with the video index based on the generated video index and the first video. By clicking on the video index, the user can start playing the target video from the moment the target subject enters the frame.

[0030] The target object is the subject in the captured video, which can be a person, scenery, etc.

[0031] The video index may be an identifier that can represent the target object, and the video index corresponds to the moment when the target object appears in the frame. The user can click on the video index to jump to the moment when the target object appears in the frame for playback. It is understood that the user can adjust the playback progress of the target video by clicking on the video index. The first video is the video obtained by video recording.

[0032] The target video includes an automatically generated video index. The user can perform operations on the video index to start playing the target video from the playback time corresponding to the video index.

[0033] For example, when a user shoots a portrait video, when person A enters the frame, the electronic device can detect that person A is included in the video recording interface and automatically generate an index of person A, and the index corresponds to the moment when person A enters the frame. When the video recording is completed, the user can click the index to jump to the moment when person A enters the frame for playback.

[0034] In an embodiment of the present application, when an electronic device detects that a target object is included in a video recording interface during video recording, the electronic device automatically generates a video index, which corresponds to the moment when the target object appears in the target video. When a user watches the target video, the video index is used to quickly locate the moment when the target object appears in the target video, allowing the user to quickly locate the playback moment they want to watch without the user having to manually adjust the video progress multiple times, thereby saving the user's time.

[0035] In some embodiments of the present application, during a video recording process, when a target object is included in a video recording interface, a video index is generated, including: when a target object is included in the video recording interface, a first input is received; in response to the first input, a first target identifier is searched in a preset identifier list, the first target identifier being associated with an input feature of the first input; and a video index is generated based on the first target identifier.

[0036] In an embodiment of the present application, when the electronic device determines that the video recording interface includes a target object, that is, when the electronic device recognizes the target object, the electronic device can simultaneously find the first target identifier corresponding to the target object in the preset identifier list based on the user's first input and generate a video index.

[0037] The first input may be an input issued by the user when the target object appears, which enables the electronic device to recognize the target object. Specifically, the input method of the first input may be voice input, gesture input, keyboard input or other input that can be recognized by the electronic device; the input content of the first input may be the name of the target object or other information that can represent the characteristics of the target object.

[0038] The preset identifier list is a list stored in advance by the user. The preset identifier list includes multiple first target identifiers and the input features of the first input corresponding to the multiple first target identifiers. The input features are related to the input form of the first input. For example, when the first input is voice input, the input feature is the voice content. In the preset identifier list, the multiple voice contents correspond one-to-one to the multiple first target identifiers. When the first input is a sliding input, the input feature is the sliding trajectory. In the preset identifier list, the multiple sliding trajectories correspond one-to-one to the multiple first target identifiers.

[0039] It should be noted that before the video recording starts, a preset identification list is obtained. The preset identification list is a first target identification list of target objects entered in advance by the user in the electronic device. The first target identification can be entered in a variety of ways. Specifically, it can be entered in the form of voice, manual typing, or entering a picture with the first target identification information.

[0040] Specifically, when a user records a video, the electronic device can identify the target object that appears in the video. After the target object is identified, the electronic device can receive and respond to a first input from the user. Based on the first input, the electronic device can find the first target identifier corresponding to the above-mentioned target object in the preset identifier list, and use the first target identifier to generate a video index of the target object when recording the video.

[0041] Figure 2FIG. 1 shows one of the schematic diagrams of the shooting preview interface provided by the embodiment of the present application. Figure 2 As shown, when a user records a video of a person, after a target object 202 appears in the video screen 200, the user performs voice input 210 to the electronic device, for example, speaking the name of the target object 202. The electronic device can recognize the user's voice and find the first target identifier 204 of the target object pre-stored in the preset identifier list, wherein the first target identifier 204 can be the name information of the target object, and the first target identifier 204 is inserted as a video index 206 into the position 208 corresponding to the moment when the target object enters the video.

[0042] It should be noted that, during the video recording process, when a target object is identified to appear in the video, the electronic device displays a prompt message to prompt the user to perform a first input to set a corresponding video index for the target object in the first video.

[0043] If the electronic device does not receive the first input within a preset time period after the electronic device displays the prompt information, it is determined that the user gives up setting the video index for the target object.

[0044] In the embodiment of the present application, the electronic device can find a first target identifier corresponding to a target object in a preset identifier list based on a first input from a user, and generate a video index based on the first target identifier. During video recording, the user can control the timing of video index generation through the first input, so that the generated video index better meets the user's actual needs.

[0045] In some embodiments of the present application, generating a video index according to the first target identifier includes: generating a video index according to the entry moment of the target object and the first target identifier, and the entry moment of the target object is at least one.

[0046] In an embodiment of the present application, when a target object appears multiple times during video recording, the electronic device can generate a video index each time the target object appears in the frame, and the first target identifier corresponding to the same target object is the same.

[0047] Specifically, when a target object appears for the first time, the electronic device generates a video index at the moment the target object first appears in the frame based on the first target identifier found. After the video index is generated for the target object using the first target identifier for the first time, a corresponding relationship is established between the target object and the first target identifier. When the target object appears again, the electronic device can automatically generate a video index at the moment the target object first appears in the frame based on the first target identifier, without the user having to repeat the operation.

[0048] In the embodiment of the present application, when the target object appears for the first time, the electronic device can generate a video index based on its corresponding first target identifier, establish a correspondence between the target object and the video index, and generate the same video index for the same target object, thereby achieving the technical effect of generating the same video index for the same target object without the need for repeated user input, thereby simplifying user operations.

[0049] In some embodiments of the present application, there are multiple target objects, and the number of first target identifiers is the same as the number of target objects; based on the first target identifiers, a video index is generated, including: receiving a second input for multiple target objects; in response to the second input, establishing a mapping relationship between multiple target objects and multiple first target identifiers according to a first order, and the first order is associated with the input order of the second input for the multiple target objects; based on the entry moment of each target object and the corresponding first target identifier, a corresponding video index is generated, and there is at least one entry moment for each target object.

[0050] In an embodiment of the present application, when multiple target objects enter the frame at the same time, based on the user's first input, the same number of first target identifiers as the multiple target objects can be found. By performing a second input, the user can establish a mapping relationship between the multiple first target identifiers and the multiple target objects, wherein the second input includes the user's input performed on the multiple target objects, and the mapping relationship established between the first target identifiers and the target objects is associated with the input order of the second input on the target objects. Based on the mapping relationship, the electronic device generates corresponding video indexes for the multiple target objects according to the multiple first target identifiers.

[0051] Specifically, when a user takes a video of multiple target objects, the electronic device can first find multiple first target identifiers with the same number as the above-mentioned target objects based on the user's first input, and then establish a mapping relationship between the multiple target objects and the multiple first target identifiers based on the user's second input, and generate corresponding video indexes at the moments when the multiple target objects appear in the frame. When the above-mentioned multiple target objects appear again, the electronic device can generate a video index at the moment when the target object appears in the frame again based on the mapping relationship established previously.

[0052] The second input may be an operation initiated by the user when multiple target objects appear, enabling the electronic device to respectively establish corresponding first target identifiers for the multiple target objects. The electronic device can establish a mapping relationship between the multiple target objects and the multiple first target identifiers based on the second input.

[0053] For example, when a user captures a video of three people, the second input may be a voice input in which the user sequentially speaks the names of the three characters according to the order in which they appear, where the order of the three names in the voice input is the first order. The electronic device establishes a mapping relationship between the first target identifiers corresponding to the three names and the target objects corresponding to the three characters, based on the order of the three names in the voice input and the order in which the three characters appear in the video.

[0054] Figure 3 FIG2 shows a second schematic diagram of the shooting preview interface provided by the embodiment of the present application. Figure 3 As shown, when three target objects, namely the first object 302, the second object 304 and the third object 306, appear simultaneously on the video recording interface 300, and all of them appear for the first time, the user can click on the first object 302, the second object 304 and the third object 306 in turn, and perform voice input 318 to the electronic device, and say their corresponding names in turn. The electronic device can recognize the user's voice and find the corresponding three first target identifiers in the preset identifier list, which are three name information, namely the first name information 308, the second name information 310 and the third name information 312, and insert the first name information 308, the second name information 310 and the third name information 312 as the video index 314 into the time position 316 where the captured object appears in the video.

[0055] In the embodiment of the present application, the electronic device is able to establish an association relationship between multiple first target identifiers and multiple target objects through user input when there are multiple target objects to be recorded, thereby achieving the technical effect of enabling the electronic device to find the corresponding first target identifier based on the association relationship during the subsequent video shooting process, thereby setting a video index.

[0056] In some embodiments of the present application, during a video recording process, when a target object is included in a video recording interface, a video index is generated, including: when a target object is included in the video recording interface, determining a second target identifier based on the target object and a preset gallery; generating a video index based on the second target identifier and the moment when the target object enters the frame, wherein the moment when the target object enters the frame is at least one.

[0057] In an embodiment of the present application, after the electronic device determines that the target object is included in the video recording interface, that is, the electronic device recognizes that the recorded video includes the target object, the electronic device can find the second target identifier corresponding to the target object in the preset gallery, and generate a video index with the second target identifier for all moments when the target object appears in the frame.

[0058] Specifically, when a user is recording a video of a target object, the electronic device can identify the first image feature of the target object, and can find the second target identifier corresponding to the target object in a preset gallery based on the first image feature of the target object, so that the electronic device can use the second target identifier to generate a video index at all moments when the target object appears in the frame.

[0059] The preset gallery includes pictures of the target object and second target identifiers corresponding to the pictures of the target object. The electronic device can search the preset gallery for the second target identifier corresponding to the target object based on the identified first image feature of the target object.

[0060] It should be noted that before video recording begins, a preset gallery is retrieved. This is a gallery list of images of target objects and their second target identifiers, which are stored in the electronic device in advance by the user. Each target object in the preset gallery contains multiple images, thereby improving recognition accuracy when searching the preset gallery for the second target identifier corresponding to the target object.

[0061] The second target identifier can be an identifier in a preset gallery that represents characteristic information of the target object. The electronic device can generate a video index corresponding to the target object based on the second target identifier. For example, the second target identifier can be the target object's name, photo thumbnail, etc.

[0062] In an embodiment of the present application, during the process of video recording by an electronic device, a second target identifier corresponding to the target object can be found in a preset gallery through image recognition, thereby generating a video index of the target object, achieving the technical effect that when recording a video, the electronic device can automatically generate a video index through a preset gallery without the need for user operation.

[0063] In some embodiments of the present application, determining the second target identifier based on the target object and the preset gallery includes: searching for the target image in the preset gallery based on the first image feature of the target object; determining the second target identifier based on the target image, and the preset gallery stores the second target identifier corresponding to the target image.

[0064] In an embodiment of the present application, since the preset gallery stores the target image corresponding to the target object and the second target identifier corresponding to the target image, after the electronic device identifies the photographed target object, it can find the corresponding target image in the preset gallery based on the first image feature of the target object, and generate a video index based on the second target identifier corresponding to the target image.

[0065] Specifically, when a user is recording a video of a target object, after the electronic device identifies the target object, it can find a target image corresponding to the target object in a preset gallery based on the first image feature of the extracted target object, and generate a video index at the moment when the target object appears in the frame based on the second target identifier corresponding to the found target image.

[0066] Figure 4 The third schematic diagram of the shooting preview interface provided by the embodiment of the present application is shown. Figure 4 As shown, when the user records a video of a target object 402, a plurality of target images of the target object are pre-stored in the preset gallery. After the electronic device identifies the target object 402, it searches for the corresponding target image in the preset gallery. When the target image corresponding to the target object is found, the electronic device can generate a video index 406 with the second target identifier 404 at the moment when the target object 402 appears in the frame, based on the second target identifier 404 corresponding to the found target image, wherein the second target identifier is selected as name information.

[0067] The embodiment of the present application limits the electronic device to using image recognition means to find the second target identifier corresponding to the target object in the preset gallery, so as to generate the specific process of the video index of the target object. This achieves the technical effect that when recording a video, the electronic device can automatically generate a video index through the preset gallery without the need for additional user operation.

[0068] In some embodiments of the present application, after generating the target video based on the first video and the video index, it also includes: receiving a third input of the target index in the video index; in response to the third input, playing the target video from the target time point, and the target time point is associated with the entry moment of the target object corresponding to the target index.

[0069] In an embodiment of the present application, after the electronic device generates a target video with a target index, the user can jump the target video to a target time point through a third input.

[0070] Specifically, after the electronic device generates a target video based on the recorded first video and the video index, the user can select the target index in the video index according to his or her own needs to jump the target video to the target time point corresponding to the target index for playback.

[0071] The target index is the index of the moment of entry of the target object that the user wants to jump to in the video index generated by the electronic device. The user can jump the target video to the target time point corresponding to the target index through the target index.

[0072] The target time point is the moment when the target object corresponding to the target index appears in the frame. The user can clearly grasp the specific time when the target object appears through the target time point.

[0073] Figure 5 Schematic diagram of the video playback interface provided by the embodiment of the present application is shown. Figure 5 As shown, below the generated target video playback interface 500, a video index 502 is displayed, which contains a target index 506 corresponding to the target object 504. When the user clicks the target index 506, the target video can jump to the target time point 508 where the above-mentioned target object 504 appears for playback.

[0074] The embodiment of the present application enables users to jump to the target time point corresponding to the target index in the video index according to their own viewing needs, thereby achieving the technical effect of enabling users to quickly locate and play the target video.

[0075] In some embodiments of the present application, after generating a target video based on the first video and the video index, it also includes: extracting at least one second image feature and a third target identifier in the target video based on the video index, the second image feature and the third target identifier corresponding one-to-one, the second image feature is the image feature of the target object, and the third target identifier is the identifier corresponding to the target object; generating a target identifier list based on the second image feature and the corresponding third target identifier, the target identifier list is used to find the corresponding third target identifier based on the second image feature in the video during the video recording process.

[0076] In an embodiment of the present application, after the electronic device generates a target video with a video index, the electronic device can generate a target identifier list based on the second image feature in the target video and the third target identifier corresponding to the second image feature. When the electronic device records another video again, if the other video includes the second image feature stored in the target identifier list, the electronic device can find the corresponding third target identifier in the target identifier list and generate a corresponding video index in the video based on the third target identifier.

[0077] Specifically, the electronic device can identify a second image feature in the target video through image recognition technology. The number of second image features can be multiple, and each second image feature corresponds to a target object. The electronic device can find a third target identifier corresponding to the second image feature based on the video index in the target video. Then, a mapping relationship is established between the identified third target identifier and the corresponding second image feature, and the mapping relationship is stored in a target identifier list, so that the electronic device can generate a video index based on the target identifier list when subsequently recording other videos.

[0078] It should be noted that after generating the target identifier list, the electronic device can continuously update the target identifier list. The electronic device can determine the third target identifier and the corresponding second image feature in the subsequently captured video based on the video index in the subsequently captured video, and update the target identifier list accordingly.

[0079] In an embodiment of the present application, the electronic device can extract the second image feature and the third target identifier corresponding to the second image feature from a target video including a video index, and generate a target identifier list based on the corresponding second image feature and the third target identifier. When the electronic device subsequently records a video including the second image feature, the third target identifier in the target identifier list can be reused to generate a video index, thereby improving the efficiency of the electronic device in generating video indexes in subsequently recorded videos.

[0080] In some embodiments of the present application, after generating a target video based on the first video and the video index, it also includes: receiving a fourth input, the fourth input being associated with the target object; and sending a first video clip in the target video in response to the fourth input, the first video clip being a video clip extracted from the target video based on the video index corresponding to the target object.

[0081] In an embodiment of the present application, after an electronic device generates a target video with a video index, if the electronic device receives a fourth input associated with a target object in the target video, the electronic device can find a first video clip in the target video based on the target object and the video index, extract the first video clip, and send the first video clip separately. Exemplarily, the fourth input can be voice input, and the electronic device can find the corresponding target object and the corresponding video index based on the voice input. The fourth input can also be text input, and the electronic device can find the corresponding target object and the corresponding video index based on the text input.

[0082] Specifically, when a user needs to send a first video clip related to a target object in a target video through a social software, the user enters query information of the target object in an input box in the interface for selecting a target video. The electronic device can determine the target object in the target video based on the query information and determine a corresponding video index based on the target object. The target object can correspond to multiple video indexes. The electronic device extracts at least one first video clip based on the video index corresponding to the target object and sends the first video clip.

[0083] In the case where there are multiple first video segments, the electronic device splices the multiple first video segments according to the order in which the multiple first video segments appear in the target video and then sends the spliced ​​segments.

[0084] In an embodiment of the present application, when a user needs to send a first video clip including a target object in a target video, the user only needs to perform a fourth input related to the target object on the electronic device, and the electronic device can automatically search and extract the first video clip including the target object in the target video for sending, without the user having to manually crop the target video, thereby simplifying the user's operation.

[0085] The video generation method provided in the embodiment of the present application can be executed by a video generation device. In the embodiment of the present application, the video generation device provided in the embodiment of the present application is described by taking the video generation method executed by the video generation device as an example.

[0086] In some embodiments of the present application, a video generating device is provided. Figure 6 FIG. 1 shows a schematic diagram of the structure of a video generating device provided in an embodiment of the present application. Figure 6 As shown, the video generating device 600 includes:

[0087] A generating module 602 is configured to generate a video index when a target object is included in the video recording interface during the video recording process. The video index is associated with the moment when the target object appears in the video.

[0088] The recording module 604 is configured to obtain a first video after recording is completed;

[0089] The generating module 602 is further configured to generate a target video according to the first video and the video index.

[0090] In an embodiment of the present application, the electronic device can, during the video recording process, generate a corresponding video index for the target object when it detects that the video recording interface includes a target object. The video index corresponds to the moment when the above-mentioned target object enters the frame, that is, the position of the video index can change with the change of the moment when the target object enters the frame. After the electronic device finishes the video recording, it can generate a target video with a video index based on the obtained first video and the video index.

[0091] In an embodiment of the present application, when an electronic device detects that a target object is included in a video recording interface during video recording, the electronic device automatically generates a video index, which corresponds to the moment when the target object appears in the target video. When a user watches the target video, the video index is used to quickly locate the moment when the target object appears in the target video, allowing the user to quickly locate the playback moment they want to watch without the user having to manually adjust the video progress multiple times, thereby saving the user's time.

[0092] In some embodiments of the present application, the video generating apparatus 600 further includes:

[0093] A first receiving module, configured to receive a first input when the video recording interface includes a target object;

[0094] a search module, configured to search for a first target identifier in a preset identifier list in response to a first input, the first target identifier being associated with an input feature of the first input;
