[0030] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0031] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

[0032] The inventors discovered through research that existing online collaborative video creation methods are costly to produce. For example, if multiple users need to record their online interactions or different users' viewing of the same video, each user needs at least two devices (such as a mobile phone and a computer simultaneously) to record, project, and interact online simultaneously. Furthermore, multiple software tools need to be running concurrently, which is not only time-consuming and labor-intensive, but also only produces a screen recording, making further editing difficult. Additionally, directly recording each user's video and then integrating multiple videos requires each user to transmit their recording to a designated user for editing, which is also time-consuming, labor-intensive, and costly. To address at least one of these problems, this disclosure provides a video editing method, apparatus, device, and medium, which are described in detail below.

[0033] Figure 1 This is a flowchart illustrating a video editing method provided in an embodiment of the present disclosure. The method can be executed by a video editing device, which can be implemented using software and / or hardware, and is generally integrated into an electronic device. Figure 1 As shown, the method mainly includes the following steps S102 to S106:

[0034] Step S102: Acquire multiple target videos, which include first videos captured and recorded by different user devices for the same recording task.

[0035] User devices can be mobile phones, computers, wearable devices, etc., and are not limited herein. In practical applications, there can be multiple user devices, and each user can use only one user device. When multiple users perform the same recording task, they can use their respective devices to shoot and record, thereby obtaining a first video corresponding to each device. This disclosure does not limit the recording task. For example, the recording task can be to use the front-facing camera of the user device to shoot the user's behavior, for example, to shoot the user's behavior when interacting online; or the recording task can be to use the user device to shoot the scene in which the user is located, etc. The specific recording task can be flexibly set according to the needs, and this disclosure does not impose any restrictions.

[0036] It should be noted that in practical applications, the target video may include not only the first video. For example, the target video may also include a third video derived from the second video, where the second video is played on different user devices during the recording process for the recording task, and the third video is used to present the playback status of the second video during the recording process. That is, the target video may also include a third video derived from the second video played synchronously on different user devices during the recording process. This third video can present the playback status of the second video during the recording process, so that it can be used in video editing together with the first video in later stages.

[0037] For example, multiple users can simultaneously watch a second video, meaning each user's device plays the second video synchronously, while each user's viewing behavior is recorded using their front-facing camera. The second video can be determined by the initiator of the recording task (also known as the creator), for example, by obtaining a second video file or link uploaded by the creator, and then played synchronously on all user devices. During the playback of the second video, its playback status can be adjusted and controlled, such as speeding up playback, slowing down the video, or rewinding the video; there are no restrictions on this. The resulting third video can simply be the second video, and can be further associated with the playback control information of the second video so that the playback status of the second video can be restored based on the playback control information when the third video is played later; the third video can also be a recording of the second video, for example, recording the entire playback process of the second video. Specific settings can be flexibly configured according to needs, and there are no restrictions on this. Later, the third video obtained from the second video watched by multiple users can be combined with the first video obtained by recording each user's viewing behavior to generate a collaborative video of multiple people watching the same video content.

[0038] In practical applications, a target user device can be defined. Different user devices record a first video for the same recording task. Other user devices can send their recorded first videos to the target user device and obtain a third video through the target user device. Both the first and third videos are then integrated on the target user device for subsequent processing. Alternatively, each user device can upload both its recorded first video and the third video recorded by the target user device to a server for further processing; this is not a limitation. In some specific implementation examples, the different user devices include a first user device and a second user device. The first user device is the device that imports the second video for the recording task. Furthermore, the first user device can also be the device that initiates the recording task; that is, the first user device can both initiate the recording task and import the second video for that task. This can be flexibly configured according to requirements. When the recording task is not closed and the first user device has not exited the recording task, the target user device can be the first user device; when the recording task is not closed and the first user device has exited the recording task, the target user device can be the second user device. The second user device can be any device other than the first user device among multiple user devices performing the recording task. It can be manually designated, randomly determined, or determined according to a preset method, such as designating a user device invited by the first user device as the second user device. This approach effectively ensures the smooth execution of the recording task and video editing processing.

[0039] Step S104: Obtain editing templates corresponding to multiple target videos; the editing templates include the display position information and track information of the multiple target videos. The track information refers to the editing track information of the multiple target videos in the multi-track editor, such as the type of editing track (main track, picture-in-picture track), etc.

[0040] In practical applications, multiple editing templates can be pre-set, and users can then select the desired template from these preset options. The selected template can then be directly used as the editing template for multiple target videos. Alternatively, users (such as the initiator of a recording task) can further adjust and modify the selected template according to their needs, thereby obtaining editing templates for multiple target videos. In this embodiment, by obtaining the editing templates, the display position and corresponding editing track of each target video can be directly determined, enabling convenient and quick subsequent editing of multiple target videos.

[0041] For example, when the target video includes a third video, the video editing track corresponding to the third video is the main track, and the video editing track corresponding to the first video is the picture-in-picture track. The picture-in-picture track is the secondary track. When multiple target videos contain only the first video, the video editing track corresponding to the first video captured by a third user device in different user devices is the main track, and the video editing tracks corresponding to the first videos captured by other user devices (excluding the third user device) in the multiple target videos are the picture-in-picture tracks; the third user device is the device that initiates the recording task. In practical applications, the track correspondence for each target video can be flexibly set, such as allowing the user to specify the track for each video, etc., without limitation. In practical applications, the aforementioned third user device can not only initiate a recording task but also upload a second video. The third user device can also be the same user device as the first user device that imports the second video for the recording task, such as the creator's device; furthermore, the third user device can be different from the first user device, for example, the first user device and the third user device are devices of two different users, and the two users can upload different second videos according to their needs, without limitation.

[0042] Step S106: Based on multiple target videos and editing templates, display the video editing interface.

[0043] In some implementation examples, the video editing interface includes a preview playback area and an editing track area. The editing track area contains multiple video editing tracks, which may include a main track and one or more picture-in-picture tracks (sub-tracks). These tracks can be arranged from top to bottom, with the main track at the top or bottom, without restriction. Each target video is assigned a video track segment on one of the multiple video editing tracks based on the track information. The timeline positions of the video track segments from multiple target videos may partially or completely overlap. It is understood that the track information can indicate the track type, track position, or track identifier for each target video. Based on the track information of each target video, the corresponding video editing track can be directly determined, and the target video can be treated as a video track segment on the video editing track, facilitating editing of the video track segment composed of multiple target videos. The timeline positions of multiple target videos may partially or completely overlap. For example, if all users' recording start and end times are the same, then the timelines can be considered to completely overlap. However, if some users' recording start and end times are different from other users', such as ending recording early, then their target videos may partially overlap with the timeline positions of other users' target videos. The specific settings can be flexibly configured according to needs, and there are no restrictions here.

[0044] The images of multiple target videos are displayed in the preview playback area according to the display position information of each target video. Specifically, for each target video, its display area in the preview playback area is determined based on its display position information. In this way, the display areas of the images of multiple target videos in the preview playback area can be directly determined based on the display position information in the editing template, allowing users to clearly understand the presentation effect of each target video through the preview playback area.

[0045] In addition, the video editing interface may also include operation controls for editing tools, used to respond to user operations and trigger video editing processes. These operation controls may include text editing controls, texture editing controls, animation effects controls, and track editing controls, and are not limited thereto. This embodiment does not limit the arrangement of the above areas of the video editing interface; for example, the preview playback area can be placed above the editing track area, and the operation controls for the specified editing tools can be placed below the editing track area.

[0046] The above method allows for convenient and quick editing of videos recorded by multiple users for the same recording task, effectively reducing the cost of online collaborative video creation. The device executing this video editing method can be either a user device or a server, and it can interact with other devices during execution; no restrictions are imposed.

[0047] In some specific implementation examples, before the step of acquiring multiple recorded videos, the video editing method provided in this disclosure embodiment further includes the following steps (1) to (3):

[0048] (1) In response to receiving a video recording request from a target user device, a recording task is created, and the user interface corresponding to the recording task is displayed on the target user device; wherein, the user interface displays video addition controls and user invitation controls. For example, the recording task can be a task where multiple people watch a video together, simultaneously recording each user's viewing performance and the playback status of the video (the aforementioned second video) watched by multiple users simultaneously. This disclosure does not limit the specific implementation of creating the recording task; for example, an online chat room can be created for multiple users to enter the online chat room for online interaction and / or to watch the video played in the chat room, while simultaneously recording each user's online interaction performance and video playback status.

[0049] (2) In response to the detection that the video addition control has been triggered, the system obtains the video information uploaded by the target user device and obtains the second video based on the video information; wherein, the video information includes local video files and / or network video links. The second video is the video that multiple users watch together. In practical applications, if the target video contains the second video, the target user device can be a device that simultaneously initiates a recording task and imports the second video for the recording task. In some specific implementation examples, the target user device can be equivalent to the aforementioned first user device, which can both initiate a recording task and import the second video for the recording task.

[0050] In practical applications, various types of video adding controls can be provided to users, such as controls for uploading local video files and / or controls for entering web video links. Users can choose the desired video adding control according to their needs. Furthermore, the number of second videos can be one or more; for example, a user can simultaneously upload multiple second video files from their local machine and / or enter multiple web links for second videos. In practical applications, the uploaded video information can also be parsed. For example, when a user uploads a web video link, the link can be parsed to obtain the corresponding second video. If parsing fails, a prompt can be sent to the user to modify the web video link. Furthermore, to ensure information security, video information can be reviewed to prevent second videos from containing illegal content or from sources that do not meet preset source requirements.

[0051] (3) In response to the detection that the user invitation control is triggered, an invitation message for the recording task is generated so that the target user device can send an invitation message to the specified user device. The invitation message is used to prompt the specified user device to join the recording task.

[0052] Specifically, the user of the target user device (the user who initiates the recording task, which can be referred to as the creator) can invite a specified user by triggering a user invitation control. For example, when the creator triggers the user invitation control, an invitation password or chat room link can be displayed on the user interface so that the creator can forward the invitation information to other users. Other users can directly enter the chat room created by the creator to perform the recording task based on the invitation information.

[0053] For easier understanding, please refer to Figure 2The diagram illustrates a user interface where, after a creator initiates a duet request through a target user's device, the user interface corresponding to the recording task is displayed on the target user's device. This interface displays video addition controls and user invitation controls. Users can upload video files by triggering local controls, enter video links by triggering link controls, or directly upload video files by dragging and dropping. Furthermore, pre-set sample videos can be provided to users so they can directly use them as a second video for testing. In addition... Figure 2 The text also indicates the main creators ( Figure 2 The front-facing camera recording window of user A) can be used to display real-time recording footage including the creator's face. A user invitation control is located to the side of the creator's front-facing camera recording window. By triggering this control, the creator can obtain invitation information and invite specified users to join the chat room. At this time, the front-facing camera recording windows of the invited users will be displayed, and the position of the user invitation control will be adjusted to the outside of the front-facing camera recording windows of the most recently invited users. This continues until the number of users invited by the creator reaches a preset threshold, at which point the user invitation control will no longer be displayed. It should be noted that if the creator neither adds video nor invites users, the start recording control on the user interface will be in an untriggerable state, such as being grayed out and unable to respond to user triggering actions.

[0054] In practical applications, both the target user device and the user interfaces of other user devices performing the recording task display a first area and a second area. The first area displays images of the first video recorded by each user device, while the second area displays images of the second video. That is, each user participating in the recording task can simultaneously view the second video and also simultaneously view the user's performance recorded by the front-facing cameras of all users.

[0055] For example, see Figure 3 The diagram illustrates a user interface on a target user device, showing front-facing camera recording windows for multiple users (User A to User D) displayed on the user interface. These recording windows display the video images of each user's reactions (i.e., the first video). Figure 3 The user interface provided also displays a second video display window to show the images of the second video. During this time, the creator (let's assume it's user A) has playback control permissions for the second video and can adjust the playback status such as progress or speed of the second video at any time as needed. Figure 3The user interface is designed for the creator's video, and therefore also shows the creator the start recording control and the playback adjustment control for the second video. For participants such as users B through D, their user interface is basically the same as the creator's, allowing them to view the images of all users' reaction videos and the second video. The main difference is that the start recording control and the second video playback adjustment control are no longer displayed; that is, only the creator has control over the recording task. As can be seen from the above user interface, each user in the chat room can simultaneously watch the second video and each other's reactions, thus engaging in online interaction and further enabling multi-person collaborative video creation.

[0056] As mentioned earlier, the target user device's user interface displays a "Start Recording" control so that the user (creator) can trigger recording via this control. If neither the target user device's video addition control nor user invitation control is detected, the "Start Recording" control remains in an untriggerable state. In this untriggerable state, the "Start Recording" control cannot be used to record video. That is, if the creator has neither uploaded a video nor invited other users, the recording conditions are not met, and recording cannot begin. Therefore, the "Start Recording" control can be set to an untriggerable state, preventing users from initiating the recording process.

[0057] The "Start Recording" control becomes triggerable when the target user device triggers the video addition control and / or the user invitation control. This triggerable "Start Recording" control is used to begin video recording upon being triggered. In other words, when the creator meets the recording conditions, they can initiate the recording process by issuing a recording command through the "Start Recording" control. In practical applications, the "Start Recording" control can be displayed only on the user interface of the target user device, and not on the user interfaces of other user devices; that is, only the creator is given control over starting recording.

[0058] Based on the above, when acquiring multiple recorded videos, you can refer to steps a and b below:

[0059] Step a: In response to the detection that the start recording control in a triggerable state has been triggered, recording is performed based on the frame images captured by the front-facing camera of the user device performing the recording task to obtain the first video. Specifically, after the start recording control is triggered, each user device performing the recording task can start recording the performance video of its own user, such as capturing video frames containing the face of the user through the front-facing camera to obtain the first video corresponding to each user device.

[0060] Step b: Having obtained the second video through the target user device, the user device performing the recording task simultaneously plays the second video during the recording process and records the playback of the second video to obtain the third video. For example, each user device can simultaneously play the second video while recording the user's viewing behavior through the front-facing camera. The target user device or server can record the complete playback process of the second video, such as recording the content area of ​​the second video, including pauses, playback, progress bar dragging, audio tracks, etc., that occur during playback to obtain the third video.

[0061] In practical applications, different user devices, including the target user device, provide a user interface with triggerable video operation controls on the recording task. These video operation controls, also known as the second video operation controls, are used to adjust the playback status of the second video. Other user devices besides the target user device do not have triggerable video operation controls on their user interfaces for the recording task. When the video operation controls are triggerable, in response to detecting a user-triggered operation on the target user device, the playback status of the second video is adjusted according to the user's trigger operation. That is, the target user device initiating the recording task can be granted operation permissions for the second video. The user of the target user device has the right to adjust the playback status of the second video during playback. This playback status includes, but is not limited to, pause, rewind, fast forward, and slow motion. The user of the target user device can flexibly control the playback status of the second video as needed, such as slowing down the playback speed of important content or rewinding that important content multiple times.

[0062] In specific implementation, different user devices can include a first user device and a second user device. The first user device is the device that imports the second video for the recording task. If the recording task is not closed and the first user device has not exited the recording task, the target user device is the first user device; if the recording task is not closed and the first user device has exited the recording task, the target user device is the second user device. In practical applications, the creator also has the authority to end the recording. Based on this, the user interface of the first user device also includes an end-of-recording control. The method further includes: if the end-of-recording control of the first user device is not detected, but the first user device stops executing the recording task, it indicates that the creator may have unexpectedly lost connection or needs to go offline midway, specifically corresponding to the situation where the recording task is not closed and the first user device has not exited the recording task. In this case, a substitute user device (i.e., the second user device mentioned above) can be determined among the different user devices, and the user interface displayed on the substitute user device when executing the recording task will present video operation controls and an end-of-recording control that can be triggered by the user. For example, the recording control can be transferred to a participant designated by the creator, or it can be transferred to the first-priority participant. The specific settings can be flexibly configured according to needs and are not limited here. In other words, by using the above method, when the main creator goes offline in advance, a substitute user can be found to continue as the new main creator to perform subsequent video playback control and end recording operations, so as to fully ensure that the recording task can be executed normally.

[0063] Furthermore, in the case where multiple target videos are obtained through the aforementioned method, this embodiment of the disclosure also provides an implementation example for obtaining editing templates corresponding to the multiple target videos, which can be performed with reference to the following steps A and B:

[0064] Step A: In response to receiving an editing request from a fourth user device among different user devices, a template selection page is displayed. Exemplarily, the fourth user device can be the user device initiating the recording task, the device uploading the second video, or a specific user device; no limitation is imposed here. That is, the fourth user device can be the same as the aforementioned first user device and / or third user device. Furthermore, the fourth user device can also be other devices specified among multiple user devices; no limitation is imposed here. In other words, in this embodiment of the disclosure, the device initiating the recording task, importing the second video, and performing video editing can be the same device or different devices, and can be flexibly set according to requirements. The template selection page includes various video layout effect diagrams. Each video layout effect diagram includes multiple areas, and each area corresponds to a video display position and a video editing track. That is, the video layout effect diagram can display the window display area of ​​each target video, thereby presenting the relative positional relationship between the various target videos. The display position of the target video is different in different video layout effect diagrams. In this embodiment, the video editing track for each area can be preset. Users do not need to set the video track. By selecting the video layout effect diagram, the display position and video editing track corresponding to each target video can be automatically determined, which helps to further improve video editing efficiency.

[0065] Step B: In response to the detection of a selection operation for a target effect image among multiple video layout effect images, the editing template corresponding to the target effect image is determined for multiple target videos.

[0066] The video layout mockups visually present the display position of each video on the interface and the relative positions of different videos. Therefore, users can easily and quickly select the desired target mockup from multiple video layout mockups. Each video layout mockup corresponds to an editing template. After selecting a target mockup, the user can directly use the editing template corresponding to the target mockup as the editing template for multiple target videos. Users can also further personalize the editing template of the target mockup according to their needs and use the adjusted template as the editing template for multiple target videos.

[0067] In some implementation examples, steps B1 to B2 can be performed as follows:

[0068] Step B1: Based on the target image selected by the target user from various video layout renderings and multiple target videos, display layout preview images of multiple target videos.

[0069] For easier understanding, please refer to Figure 4The illustrations show various layout effects, specifically six simplified video layout effects. Each effect indicates the display area and relative position of different target videos. Users can select the desired target effect image and, based on the video display positions indicated by the target effect image and multiple target videos, easily and quickly generate layout preview images for multiple target videos. This clearly and intuitively presents the display effect of multiple target videos during post-editing. Furthermore, users can adjust the proportion of each video display area indicated by each layout effect while maintaining the relative position of each video display area. Alternatively, users can further adjust the relative position of each video display area based on a selected target effect image for personalized settings; there are no restrictions on this.

[0070] Step B2: Based on the target user's adjustment of the display position of the target video in the layout preview image, determine the editing templates corresponding to multiple target videos.

[0071] In practice, each video layout mockup corresponds to an initial editing template. First, based on the target mockup selected by the user, the corresponding initial editing template, and multiple target videos, layout preview images for multiple target videos are generated. The display position of each target video in the layout preview image is determined based on the display position information of each target video indicated by the initial editing template corresponding to the target mockup. Based on the user's adjustments to the display positions of the target videos in the layout preview images, the display position information of the initial editing template corresponding to the target mockup is adjusted to obtain the target editing template, which is the editing template corresponding to the aforementioned multiple target videos. The main difference between the target editing template and the initial editing template corresponding to the target mockup lies in the different display positions of the target videos adjusted by the user.

[0072] This disclosure also provides a method for users to adjust the display position of target videos. For example, users can adjust the display position of target videos by dragging their floating windows. Furthermore, horizontal and vertical layouts can be preset. If one or more floating windows of target videos are dragged to a first designated area, a horizontal layout is displayed to the user; for example, multiple first videos are arranged horizontally above a third video. If one or more floating windows are dragged to a second designated area, a vertical layout is displayed to the user; for example, multiple first videos are arranged vertically to the side of the third video. Through the above methods, the layout of multiple target videos can be conveniently and quickly adjusted, thereby quickly determining the corresponding editing template for multiple target videos.

[0073] After identifying the corresponding editing templates for multiple target videos (i.e., the target editing templates mentioned above), importing the target videos into the target editing templates generates a video editing draft. This video editing draft can be considered a project file, containing materials such as videos, as well as editing operation information for those materials. The video editing draft can then be imported into the multitrack editor. In other words, the editing draft displayed in the multitrack editor is based on the target videos imported from the target editing templates. This presents the user with a video editing interface, allowing them to directly edit multiple target videos, ultimately generating a pre-edited fourth video, also known as a collaborative video or co-created video.

[0074] The above method significantly reduces the editing costs of online collaborative video creation. Multiple users are not restricted by geographical location, and each only needs to use one device and open one software application capable of executing the video editing method provided in this disclosure embodiment to conveniently and quickly achieve the purpose of video collaborative creation. For ease of understanding, this disclosure embodiment also... Figure 5 The flowchart illustrates a video editing method, showing the operation flow of the creator (corresponding to the target user device that initiated the recording task) and participants (corresponding to the invited user devices) before, during, and after recording. Before recording, the creator can trigger the creation of a chat room through the duet function, import the video (the second video mentioned above) that all users need to watch together during the recording task into the chat room interface, and then invite participants by triggering user invitation controls. Participants can directly enter the chat room after receiving the invitation. During recording, the creator has permissions to start recording, play / pause the video everyone is watching, and confirm completion of recording. Participants simply need to watch the video with the creator and complete the recording accordingly. After recording, the creator can select a template and download the participants' reaction videos (i.e., the videos recorded by the participants' devices showing their reactions to the video). Participants only need to upload their reaction videos directly. The creator can download the videos from each participant in the background, import all the recorded videos into a multi-track editor for editing, and finally submit the final edited video. The above methods enable convenient and quick online video co-creation, greatly saving the cost of multi-person video co-creation and effectively improving the user experience.

[0075] Corresponding to the aforementioned video editing methods, Figure 6 This is a schematic diagram of a video editing device provided in an embodiment of the present disclosure.
