In practical applications, the above steps may be implemented by one electronic device, or may be implemented by a plurality of electronic devices in cooperation. Such as mobile devices like cell phones, cameras, etc. Taking a mobile phone as an example, the method can be realized by calling a special application program carried in the mobile phone, can also be realized by calling a small program set in an instant messaging application or other types of applications, and can also be realized by calling a cloud server through mobile phone application.
Taking a golf ball as an example, specifically, the electronic device shooting device may be a mobile terminal, for example, a mobile phone, or a wearable device, such as smart glasses, or a professional shooting device, such as a camera, and applications and hardware modules for implementing various functions in a shooting end may be loaded in the camera. The camera may be held by a professional camera or by a caddie, coach or other player of the same group.
To facilitate capturing the performance of the game for each player, more game-related video may be further captured. Optionally, the terminal devices entering the preset spatial range can access the service platform through registration, so that the registered terminal devices can be used as shooting terminals to upload various shot videos to the service platform.
For example, after a player participating in a competition, a related staff (a caddie, a coach, a court staff, etc.), a live audience, etc. enters a competition field or a nearby range, the player can register the player in the service platform through the terminal device carried by the player, so that the registered terminal device is used as a shooting end, and various shot videos are uploaded to the service platform. Such as live conditions, auditorium conditions, player live interactions, player interviews.
The following describes each step in the video generation method with reference to a specific embodiment.
First, in 101, a video generation interface including a photographic subject is displayed.
Wherein the subject may be determined by the type of activity. Such as players, spectators, referees at sporting events, actors, presenters, spectators at entertainment shows. Of course, the present application can set scene elements of various activities as photographic subjects in addition to the active human operators of the above examples. Scene elements of various activities are, for example, a tee, a ball bar, a net, a playing field in a sports event, and further, for example, a performance field panorama, set elements, smoke, fireworks in a entertainment performance.
It should be noted that there are various ways to select the photographic subject. The shooting objects to be displayed on the video generation interface can be selected in the following modes:
in an optional embodiment, the shot object in the video generation interface can be manually selected, and then the shot object is selected from a plurality of objects to be selected. For example, one or more objects to be selected in the video generation interface are identified, the objects to be selected in the video generation interface are selected by using a box frame, and a box corresponding to the shooting object to be selected is clicked. Optionally, the visual characteristics of the object to be selected in the video generation interface can be pre-entered. For example, the visual characteristics of each player are entered before the game begins. Such as taking an image of the face of each athlete, or an image of the apparel of the athlete.
In another optional embodiment, the shooting device can be moved to move the object to be selected in the video generation interface to a specified position, so that the shooting object is identified. For example, the focus mode is selected as the center focus, and in this case, the subject to be selected in the center of the video generation interface is set as the subject to be photographed.
Optionally, a director conversation control, a volume adjustment control, a lens conversion control, and a live broadcast state switching control may also be loaded in the video generation interface. The method is used for adjusting the display state of the shooting object in the video generation interface.
After the shooting object is selected in the above mode, the target video can be generated through the subtitle editing area loaded in the video generation interface.
In the embodiment of the application, a subtitle editing area is superimposed on a video generation interface. The subtitle editing region is mainly used for editing subtitle content. For example, the user may configure the specific content in the subtitle by selecting the subtitle configuration parameter in the subtitle editing region. The specific subtitle content includes, for example, preset subtitle content and a preset blank content field for carrying lead-in information. According to actual requirements, the setting of the specific content of the subtitle can further comprise: font color, font size, font type, etc.
Optionally, a subtitle editing control is also loaded in the video generation interface. The subtitle editing area can be called by a subtitle editing control of the video generation interface. For example, triggering a subtitle edit control may call out a subtitle edit region in a video generation interface.
Optionally, before 102, the step of loading the subtitle configuration parameter corresponding to the photographic subject in the subtitle editing region specifically includes: and identifying the shooting object currently displayed in the video generation interface, and loading the subtitle configuration parameters corresponding to the shooting object currently displayed in the subtitle editing area.
In another embodiment, before 102, if a plurality of object identifiers are loaded in the subtitle editing area, in response to a selection instruction for the object identifiers, subtitle configuration parameters corresponding to the selected object identifiers are loaded in the subtitle editing area.
In the application, the subtitle editing area can be suspended above the video generation interface, or can be arranged in a setting area of the video generation interface. The layout of the subtitle editing region can be set according to the video generation interface, for example, the subtitle editing region shown in fig. 2 is laid out on the right side or the left side of the interface according to the user use habit (such as dominant hand), so that the subtitle can be edited by one-hand operation. The subtitle editing area shown in fig. 3 may be divided into two parts, which are respectively disposed on the left and right sides of the interface, so that the subtitle is edited by two-hand operation. Alternatively, different portions of the subtitle editing area are presented in multiple occasions. For example, in fig. 3, the subtitle editing area 1 is displayed first, and the subtitle editing area 2 is displayed after the player or team is selected.
It is to be understood that the layout form of the subtitle editing area in the video generation interface is not limited to the above example. The subtitle editing area can be arranged according to the interface forms of different terminal devices or the operation habits of different users. For example, assuming that the subtitle editing region does not set a fixed range, in this case, the controls loaded in the subtitle editing region may be dynamically distributed in the video generation interface. Specifically, it is assumed that the control loaded in the subtitle editing region is firstly laid out at an initial setting position, and then the control loaded in the subtitle editing region is dynamically adjusted to other positions by the user through dragging or other forms of operation so as to adapt to the use habits or preferences of the user.
In the present application, the control loaded in the subtitle editing area may be determined by the activity type. For example, the shooting object is a player in a sports event, and the controls loaded in the subtitle editing area are set according to rules of the sports event. Such as event rules, scoring rules, score setting rules. For another example, the shooting object is a related person or a scene in a commercial activity, and the control loaded in the subtitle editing area is set according to factors such as an activity process, a site machine position setting, a shooting angle and the like. Optionally, a subtitle generating control and a subtitle configuration parameter corresponding to the shooting object are loaded in the subtitle editing area.
In the subtitle editing area shown in fig. 2, a subtitle generation control, an undo control, and a subtitle arrangement parameter corresponding to a photographic subject are loaded, taking a golf game as an example. Based on the interface, in 102, in response to a selection instruction of the subtitle configuration parameters, a target subtitle to be generated and a video generation duration matched with the target subtitle are determined. And aiming at different activity types, the subtitle configuration parameters associated with the current activity type can be displayed, so that the display content of the subtitle editing area can be flexibly adjusted.
Optionally, the subtitle configuration parameter may be associated with a video generation duration. Thus, in 102, the target subtitle content to be generated and the associated video generation duration are determined based on the selected subtitle configuration parameters.
In the caption editing area shown in fig. 2, a caption generating control, a cancel control, and caption configuration parameters corresponding to the shooting target are loaded, taking a golf game as an example. Specifically, the subtitle configuration parameters corresponding to the photographic subject are the group, the players (i.e., the photographic subject) in the group, the current number of sticks, and the selection drop point. The number of players in the group can be set according to actual conditions.
In fig. 2, a plurality of controls constructed based on the type of the drop point are recorded in the selection drop point area, including but not limited to: lane, green, hole, lost ball, water fall, out of bounds, lane bunker, green bunker, grass growth, barrier, penalty, no-drop. Alternatively, the controls shown in the drop point region may be set according to the state of the player, for example, based on the state of the last rod of the player 1, to hide part of the controls, such as green, obstacles, etc. The cancel control is used for canceling the currently selected subtitle configuration parameter.
Based on the subtitle editing area, in 102, the currently locked shooting object can be determined by selecting the group in which the athlete is located and the group. And then, selecting the drop point type to configure the specific content of the target caption. In practical application, the specific format, language content and the matched video generation duration of the target caption can be preset.
For example, based on the interface shown in fig. 2, selecting a control such as player 1, green, etc. can determine the format and content of the target subtitle to be generated, such as "player is green". Based on this, the video generation duration matched with the green is further determined to be 10s, so that the video generation duration matched with the target caption is determined.
In the application, the display state of the control can be optionally updated according to the subtitle configuration parameters. For example, if the hole-in control shown in FIG. 2 is selected, the current pole count control will be followed by a "hole-in" script to prompt the user for the current player status, and the corresponding drop point control will be updated to the selected status.
And 103, responding to a selection instruction of the subtitle generation control, and generating a target video based on the target subtitle and the matched video generation duration. The selection instruction can be generated by triggering a subtitle generating control by a user or automatically generated by the equipment. For example, a selection instruction issued by a user is received. For example, after a shooting object which is input in advance is recognized to appear in the video generation interface, a selection instruction of the subtitle generation control is automatically generated.
Optionally, the target video to be stored is marked based on the selected subtitle configuration parameter. For example, the target video is named based on the subtitle configuration parameters. Specifically, taking a golf game as an example, the naming rules of the target video are, for example, event identification, player, number of strokes, and location. For example, in the 8599 game, zhang Sanqiu member 18 th hole third stick hole video may be named Zhangthree _ H18_ S3Holed _01_8599.
In the above or below embodiments of the present application, there are a plurality of devices that display a video generation interface including a photographic subject, and the plurality of devices include a master device and a slave device. For example, a plurality of accounts are bound in advance, the primary account is set as a primary device, and the secondary account is set as a secondary device. Based on this, in the embodiment of the application, a selection instruction of a subtitle generation control in the slave device is also responded, and the target video is generated based on the target subtitle and the video generation duration in the master device is triggered. For example, the primary account number is responsible for taking a picture (or subtitles as well), and the secondary device is responsible for taking subtitles. The caption operation interface of the slave equipment is the same as the primary account interface, and when a caption is clicked, a corresponding instruction is automatically sent to the primary account, the primary account is controlled to automatically overlap a corresponding target caption, and a target video is recorded.
In the caption editing area shown in fig. 2, the caption generating control includes, but is not limited to: the system comprises a track map control for triggering generation of track map subtitles, a performance composition subtitle control for triggering generation of group performance subtitles, a name subtitle control for triggering generation of name subtitles and a batting subtitle control for triggering generation of batting subtitles. Specifically, the track map control is used to generate a drop point caption for a player playing a ball.
Specifically, in an alternative embodiment, it is assumed that the image including the photographic subject shown in the video generation interface is a live video. In short, the live broadcast picture is displayed in real time in the video generation interface, so that the target video can be directly intercepted from the live broadcast picture in the subsequent steps.
Based on this, in 103, in response to a selection instruction of a subtitle generation control, a target video is generated based on the target subtitle and the video generation duration, which specifically includes:
generating a target caption based on the selected caption configuration parameter; overlaying a target subtitle in a live video; and intercepting a video clip which is superimposed with a target subtitle and has the duration as the video generation duration from the live video to serve as the target video.
Specifically, a selection instruction of a batting subtitle control is received, a target subtitle is generated based on the selected subtitle configuration parameters, and the target subtitle is superposed to a live video displayed on a current interface. And simultaneously, triggering the recording operation of the live video displayed on the current interface based on the selection instruction, wherein the recording duration is the video generation duration matched with the target caption, so as to obtain the target video matched with the target caption. The target subtitles are superimposed in the target video, and the time length of the target video is the video generation time length matched with the target subtitles.
In practical application, the video generation durations corresponding to different subtitle configuration parameters are different. Taking golf as an example, the duration corresponding to a tee caption is 20s, the duration corresponding to a normal tee caption (e.g., a tee caption control) is 15s, the duration corresponding to a putting green putter is 12s, the duration corresponding to a today's achievement caption (e.g., a composition achievement caption control) is 8s, the duration corresponding to a hole-by-hole achievement caption is 15s, and the duration corresponding to a track caption is 25s.
Or the video generation duration corresponding to different subtitle generation controls is different. For example, the video generation duration corresponding to the track map control is 10s, the video generation duration corresponding to the composition performance subtitle control is 8s, and the video generation duration corresponding to the name subtitle control is 5s. Further, the video generation duration corresponding to the caption hitting control is determined according to different caption configuration parameters. For example, the time length corresponding to the hole entry control is 6s, the time length corresponding to the lane control is 7s, and the time length corresponding to the green control is 6.5s.
Optionally, it is assumed that a generation delay control is further loaded in the video generation interface. Based on the above, after the selection instruction of the subtitle generation control is triggered, the generation delay control can be displayed in the current interface. And further responding to a selection instruction of the generation delay control, and increasing the video generation time of the target video. And the increased video generation duration is the sum of the video generation duration matched with the target caption and the increment duration corresponding to the generation delay control. For example, the recording time is extended by 5s after each selection of the generation delay control. Further, the number of times that each type of target video can be extended can also be set.
In order to save the space occupied by the subtitle editing area in the video generation interface, in the embodiment of the present application, optionally, after the subtitle generation control is to be triggered, optionally, the currently displayed video generation interface may be switched to another video display interface, and the subtitle editing area is hidden in the video display interface. In practical application, optionally, the generation delay control may be loaded in the video display interface.
In the video generation method shown in fig. 1, the target subtitle is configured by selecting the subtitle configuration parameter in the subtitle editing region, and the target video is generated based on the target subtitle and the matched video generation duration, so that a brand-new video generation mode is realized, a video segment matched with the target subtitle is synchronously generated when the target subtitle is added, the editing process of the video segment is greatly simplified, and the video editing efficiency is improved.
In the foregoing or following embodiments, optionally, the present application may further determine whether the target subtitle is associated with a shooting object currently displayed in the video generation interface; and if the target subtitle is associated with the currently displayed shooting object, increasing the video generation duration of the target video. And the increased video generation duration is the sum of the video generation duration matched with the target caption and the increment duration corresponding to the type of the target caption.
For example, assuming that the target caption is a hole caption, based on this, if the photographic subject in the target video being recorded is a corresponding player, the video generation duration of the target video is automatically added to the incremental duration corresponding to the type to which the hole caption belongs. Optionally, the different types of hole-entering subtitles have different corresponding increment durations. For example, the increment duration corresponding to the caption of the hole-by-hole achievement is 8s per hole, or the increment duration corresponding to the caption of a certain athlete for putting a ball in a certain hole is 5s.
Furthermore, if the target subtitle is not associated with the currently displayed shooting object, the method and the device can also query the video segment associated with the target subtitle and merge the target video and the video segment associated with the target subtitle.
For example, continuously assuming that the target caption is a hole-entering caption, based on this, a video segment corresponding to the shooting object is automatically queried, and the target video is merged with the corresponding multiple video segments. Taking golf as an example, the goal video of Zhang III is merged with the corresponding goal video segment.
