Exemplary Video Processing Method

FIG. 1 is a flowchart illustrating an exemplary video processing method according to an embodiment. The method can be implemented in hardware and/or software, and can be configured in an electronic device.

The method of this embodiment starts at step 101, wherein at least one time mark may be set on the source video.

Here, for ease of understanding, some concepts involved in the embodiments are first explained.

The "source video" described herein is relative to the "sub-video" and is not intended to impose any limitations on the video itself, but is intended to mean that the sub-video is one or more parts of the source video, or that the sub-video is derived from The source video is generated directly or after processing.

In an embodiment, the source video is, for example, a video shot for sports events, e-sports competitions, film and television works, programs, etc. (hereinafter referred to as "processes"), which may be live videos or rebroadcast or transcribed videos. An "event" described herein is a sub-process of a process, such as a sub-process that is generally of interest to a user, such as a key event in a sporting event (such as a shot, a goal), a highlight in a movie or program, and the like.

The source video may be obtained by any means, such as filming (recording), wired transmission, wireless transmission, and the like. The method of shooting the source video is not limited to the common recording method, that is, the recording method of recording the video at a normal speed. In some embodiments, the source video may be recorded in a slow-motion recording method, or other methods may be used. In some embodiments, the source video may also be obtained from an external device, such as another device, client, server, or the like.

The time stamp is used to mark a certain time point in the source video, so that a specific frame in the source video can be located through the time stamp. The time stamp may represent relative time, ie, time relative to the source video itself. Time stamps may also represent absolute time, such as Greenwich Mean Time, time zone time, and the like. In some embodiments, the source video itself may have temporal information representing when it was taken. In this case, the time indicated by the time stamp can be matched with the time information carried by the source video itself. In this way, when the same source video is acquired by different devices, the correct frame located by the time stamp can be identified in combination with the time information carried by it, and the wrong frame will not be located due to different time zones or different system times of the devices. In particular, for different source videos shot by different devices for the same process (sports events, film and television works, programs, etc.), the video length, start time and end time may be different. At this time, if it is desired that the same set of time stamps can be applied to these source videos, a time stamp representing absolute time can be used. Of course, relative times can also be used, for example in cases where time stamps do not need to be applied to other source videos.

In an embodiment, one or more time stamps may be set. For example, a time stamp can be set for an event in the process. At this time, frames within a period of time forward and/or a period of time backward of the time mark may be determined to belong to the event, which is referred to herein as a "marker shift mode". In another embodiment, for example, two time markers may be set for an event in the process, and at this time, the frame(s) between the two time markers may be determined to belong to the event, which is referred to herein as "marker" Defining Patterns". Therefore, for the same set of time stamps, different rules can obtain different one or more sub-videos. Such rules can be defined as needed and can be changed at any time.

The setting of the time stamp can be achieved, for example, by triggering. FIG. 2 illustrates an exemplary interface for setting a time stamp through button triggering during a capture, according to an embodiment. As shown in Figure 2, it is assumed that the user is recording a basketball game and has recorded 5 minutes and 13 seconds. At this time, the user may, for example, determine that player A is likely to shoot a ball through the action of player A and wants to mark this shooting event. At this time, the user can touch the "Set Flag" button on the interface to set the time flag.

In the mark transition mode, the user can preset, for example, the sub-video (frame set) in the time period of 2 seconds before and 3 seconds after the time mark as the final generated sub-video. The amount of forward or backward shift can be arbitrarily set as required or according to the user's habit. In some embodiments, only one of the forward shift amount and the backward shift amount may be set. In some embodiments, these time periods may be adjusted prior to generating the sub-video.

In the flag-defining mode, the user can touch the "Set Flag" button when he thinks Player A is about to shoot to set the time flag as the start of the sub-video, and touch the "Set Flag" button again after, for example, the shot is completed to set the time flag as the start of the sub-video. Time stamp for the termination of the sub-video. In some embodiments, after the "Set Flag" button is touched to set the time flag as the start of the sub-video, a certain indication may be presented on the interface to enable the user to know that the start time flag has currently been set , which prevents user confusion. This indication can be achieved in a number of ways. In some embodiments, the display state of the "Set Flag" button itself may be changed (such as highlighted, blinking, etc.). In another embodiment, corresponding prompt information may be displayed on the interface, including but not limited to text, symbols, animations, pictures, and/or sounds.

The setting of each element on the interface shown in FIG. 2 is just an example, and various designs may be adopted or a part of them may be omitted as required.

The trigger for setting the flag may be at least one of a touch action, a key operation, a gesture, a voice input, a semantic input, and a remote command. Triggering can be implemented by software or hardware. In this case, existing hardware components of the device can be used, or dedicated hardware components can be set. In some embodiments, the trigger may be sent by remote command from a remote control communicatively coupled to the device capturing the source video and having a trigger mechanism for sending the device an command to set a time stamp.

It should be noted that the process of setting a time mark for one event is described above, but it should be understood that multiple time marks can also be set in the same manner by triggering multiple times, and one event may correspond to multiple time marks.

Furthermore, the above describes the process of setting time stamps for events, but it should be understood that other elements in the process, such as objects, may also be time stamped. FIG. 3 illustrates an exemplary interface for setting a time stamp on an object during shooting, according to an embodiment. Here, it is assumed that the user is recording a basketball game and has recorded 5 minutes and 13 seconds. However, the user may only pay attention to the performance of a certain player. In this case, the event flag may be set according to whether the player is active or not, and a corresponding label may be set instead of a certain event. The details of the label will be described below.

Returning to FIG. 1 , in step 102 , optionally, a label may be set for the time mark set in step 101 .

The tags described herein may, for example, be used to identify sub-videos generated according to their corresponding time stamps, including but not limited to the content of events (such as shots, shots, steals), objects (such as people, scenes), or the time of the event. The description can also be graphics (such as "◎" in Figure 5) and so on.

One label can be set for one time stamp, or multiple labels can be set for one time stamp. In this way, the sub-video generated from the time stamp is also associated with the tag set for the time stamp. These tags can then be used to quickly retrieve the sub-videos corresponding to them. Of course, the present application does not require to set labels on all the time markers, and only some of the time markers can be labeled, or according to the user's needs, no labels are set on the time markers.

In some embodiments, the setting of the label may be immediately after the setting of the time stamp. In this case, the setting of time stamps and labels can be done while shooting (recording) the source video. 4 illustrates an exemplary interface for setting tags when capturing video, according to an embodiment. Here, assume that the user is recording a basketball game and presses the "set flag" button when 5 minutes and 13 seconds have been recorded. In this way, the system records that a time stamp is set for the video at 5 minutes and 13 seconds. Then, as shown in FIG. 4 , for example, an interface for inputting a tag may be presented to the user in the next second, ie, 5 minutes and 14 seconds. The user can complete the setting of the label after entering the desired content and saving it. The actual interval time is not limited to the next second and can be set as required. In some embodiments, the capture of the video may continue while the tag is being entered.

In some embodiments, labels may be entered manually (such as characters, graphics). In another embodiment, one or more tags can be preset, so that the desired tag can be directly selected when inputting. FIG. 5 illustrates another exemplary interface for setting tags when capturing video, according to an embodiment. As shown in FIG. 5 , a plurality of preset label options 42 are presented in the label input interface 41 . The content of the tab option 42 can be preset. In this way, after the user has set the time stamp, the user can quickly input the label by selecting the label option 42, and at the same time, it is possible to avoid the device shaking due to manual input and thus affecting the shooting quality. In another embodiment, the corresponding label can be directly selected by touch sliding while pressing the "touch input" button. In yet another embodiment, the tag may be entered by voice. It should be understood that the label input interface 41 and the label option 42 can be set in any manner as required, and are not limited to the situations shown in FIGS. 4 and 5 .

In some embodiments, the label may be associated with the elapsed time in the flag elapsed mode. For example, when the label is set to "shooting", the sub-video in the time period 2 seconds backward from the time mark can be automatically selected to be generated. For example, when the label is set to "extraordinary", the sub-video in the time period from the time mark forward 2 seconds to the backward 3 seconds can be automatically selected to be generated. In this way, after the user selects a certain tag, the sub-video can be generated in a manner corresponding to the tag.

Returning to FIG. 1, in step 103, after the video shooting is completed, a sub-video is generated in a pre-defined manner (mark shift mode, mark definition mode, etc.) according to the set time stamp(s), and the time stamp is set The tags (if any) are automatically associated to the corresponding sub-videos. Sub-videos can be generated either at normal speed or in slow motion. The generated sub-video is then saved. It should be understood that step 103 can be executed automatically, or can be executed according to an instruction. In addition, it is also possible to include steps to change, adjust or delete the set time stamp after the video is shot.

Through steps 101 to 103, a time stamp and a label can be set during the process of shooting a video, and a corresponding sub-video can be generated after the shooting of the video is completed.

Afterwards, optionally, in step 104, one or more sub-videos may be selected from the generated sub-video(s) at any moment for synthesis to be used for generating a video highlight.

Optionally, in step 105, the generated time stamp and the information representing the corresponding relationship between the time stamp and the process for which the source video is directed can be uploaded to the external device at any time, and the corresponding relationship enables the time stamp to be correct. matched to other source videos shot for the same process. This information may include, for example, the absolute time of the time stamp. In another embodiment, the information may further include identification information of the procedure for which the source video is directed, in order to identify which procedure the time stamp is directed to. The uploaded time stamp and the above-mentioned information representing the corresponding relationship can be used by other users to generate sub-videos by applying them to another source video for the same process, for example.

Here, step 102, step 104 and step 105 are represented by dotted boxes because these steps can be omitted.

FIG. 6 shows a flowchart of an exemplary video processing method according to another embodiment. The difference between this method and the method shown in FIG. 1 is that the label is not set when shooting the video, instead, the label is set for the generated sub-video and its corresponding time stamp after the shooting ends. There is no restriction on how the label is set.

Step 601 corresponds to step 101 in FIG. 1 , and step 602 corresponds to step 103 in FIG. 1 . In step 603, a label can be set for at least one time stamp and its corresponding sub-video at any moment after the video is shot. Therefore, even if the user does not set the label during the shooting process, the required label can be supplemented in the future.

It should be understood that the method shown in FIG. 6 may be combined with the method shown in FIG. 1 , that is, a label may be set during the shooting process, and a label may be added after the shooting ends. Of course, the added tags can also be modified or deleted after the shooting.

FIG. 7 shows a flowchart of a method of merging sub-videos according to another embodiment. This process can be initiated at any time. This embodiment differs from the embodiment of FIG. 1 in that the video highlights are generated by selecting time stamps and/or tags instead of sub-videos.

The process may be followed by step 103 or step 603 in FIG. 1 , or may start at step 701, because there may be situations in which a video collection needs to be generated afterwards.

In step 701, a source video for which a video highlight is to be generated is first selected. The selection here can be the source video itself, or the title, thumbnail, etc. used to identify the time stamp(s) and/or tag(s) related to the source video, as long as the source video can be retrieved Relevant time stamp(s) and/or label(s) will suffice.

Thereafter, in step 702, the desired tag(s) are selected from the presented tag(s) associated with the source video, and then in step 703 the selected tag(s) are associated Combined sub-videos to generate video highlights. In other embodiments, sub-videos may also be merged by selecting a time stamp. In this case, the sub-video generation mode can be reset, such as a logo shift mode, a logo delineation mode, a slow motion mode, and the like. With the selection of tags, video highlights that meet specific needs can be easily generated from multiple source videos.

8 illustrates a flowchart of an exemplary method of merging sub-videos according to another embodiment. This method differs from the method shown in Figure 7 in that video highlights are quickly generated from multiple source videos by selecting tags. This embodiment assumes a situation where a user shoots multiple source videos containing a certain object (eg, a certain player) at different times and wishes to make a video highlight for the object. Of course, this embodiment does not require the object to appear in every frame of each source video, even if there are no frames related to the object in some source videos (in other words, no label is set for the object), it will not affect the implementation of this implementation. example effect.

In step 801, multiple source videos to be used for generating a video collection may be selected. In an embodiment, it is assumed that time stamps have been set for each source video by the method shown in FIG. 1 or FIG. 5 , and tags are set at least for objects of interest (eg, players), respectively.

Next, in step 802, the user may select at least one tag, eg, "Player A," from the presented group of tags associated with each source video. Then in step 803, the sub-videos corresponding to the selected tag ("player A") are merged to generate a video highlight of the player A. In this way, desired video highlights can be easily generated from multiple source videos.

In an alternative embodiment, the source video and the time stamp (which in some embodiments may further include a tag) set to it may be obtained externally. For example, for the same process (such as an event), there may be multiple devices filming from different angles. In this case, data packets including source video and time stamps (which may further include tags in some embodiments) may be received from these devices or servers. Video highlights can then be generated by the method shown in FIG. 8 .

In other embodiments, such as for the same process (eg, an event), there may be multiple devices filming from different angles. The user may just shoot the source video without setting timestamps and labels. At this point, the user may download the time stamp(s) associated with the process from another device or server. At this time, as described above, the received data may contain information on the correspondence between the time stamps and the targeted process, so that these time stamps can be correctly matched with the source video shot by the user himself.
