Based on the above technical problem, embodiments of the present application provide a video playing method, when a video including at least one moving object is being played, since a user can trigger playing of a merged video in which the video and another video including each moving object are synthesized through an input to the video, a motion parameter of a certain moving object in the at least one moving object changes according to the input parameter of the input, that is, a user can freely change a motion parameter (for example, a motion speed and/or a motion trajectory) of a moving object in a played video according to his/her own will. Therefore, the flexibility of the video playing mode is greatly improved, and the video playing mode is more humanized.

The following describes in detail a video playing method, a video playing device, and an electronic device provided in the embodiments of the present application with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

As shown in fig. 1, an embodiment of the present application provides a video playing method, which includes the following steps S101 and S102.

S101, the video playing device receives a first input of a first video.

The first video comprises N target moving objects.

Optionally, in this embodiment of the application, the first video is a currently played video.

Optionally, the first video may be a touch input, a voice input, or a gesture input of the user on the currently played first video. For example, the touch input is a sliding input on a video screen of a currently playing first video. Of course, the first input may also be other possible inputs, which is not limited in this embodiment of the application.

Optionally, the target moving object may be a living body or a non-living body. For example, the target moving object is a flying wild goose; as another example, the target moving object is a soccer ball that is kicked away.

Further, the N target moving objects may be moving objects of the same type or moving objects of different types, which is not limited in this application.

It can be understood that when the above S101 is executed, the video playing apparatus is playing the first video, so that before the above S101, the video playing method provided in the embodiment of the present application may further include: the video playing device receives input of a user on a first thumbnail; in response to the input, a first video is played. Wherein the first thumbnail is used to indicate the first video.

S102, the video playing device responds to the first input and plays the second video.

The second video is a video obtained by synthesizing a first video and N third videos, each third video includes one of N target moving objects, the motion parameters of P target moving objects in the N target moving objects included in the second video are determined according to the first input parameter, N and P are positive integers, and P is less than or equal to N.

Optionally, in this embodiment of the present application, the motion parameter may include at least one of: motion trail and motion speed. Wherein the motion trajectory also determines the direction of motion.

Optionally, in this embodiment of the application, the first video and the N third videos may be videos of a local storage space that are recorded and stored by an electronic device (i.e., a local computer); or, the video downloaded online for the electronic device; or video from other devices received (locally) for the electronic device. The method can be determined according to actual use conditions, and is not limited in the embodiment of the application.

Illustratively, the video playing device is a mobile phone, and N is 1. The handset plays the first video and, as shown in fig. 2 (a), the handset displays one video frame of the first video. Wherein the first video comprises a target moving object. As shown in (b) of fig. 2, are a plurality of video frames in the third video of the one target moving object. Therefore, the target moving object in the first video played by the mobile phone walks to the right in a straight line.

Optionally, in this embodiment of the present application, when P is equal to N, the motion parameter of each of the N target moving objects is determined according to the input parameter of the first input; when P < N, the motion parameters of only P moving objects out of the N target moving objects are determined according to the input parameters of the first input. Thus, different second videos are obtained for these two possible cases. The specific implementation mode is as follows:

first possible implementation

Optionally, P ═ N; after S101 and before S102, the video playing method provided in the embodiment of the present application may further include S103 and S104.

S103, the video playing device responds to the first input, and synthesizes a first target video frame of the first video and a second target video frame in each third video according to the input parameters to obtain M first fusion video frames.

The first target video frame and the second target video frame are video frames recorded at the same time.

Optionally, the first target video frame is any one video frame in the first video, and the second target video frame is any one video frame in each of the N third videos. Specifically, a video frame recorded at the same time in the first video and each third video is obtained, the two video frames are synthesized to obtain a first fused video frame, and so on, to obtain M first fused video frames.

Further, assume that the first video may include S video frames and each third video includes M video frames. Wherein S and M are positive integers. Since the number of frames of the M first fused video frames is determined by the number of frames of each third video frame, two possible cases may be included as follows:

the first possible scenario:

when S > M, the number of frames of video frames included in the first video is greater than the number of frames of video frames included in each third video, at this time, M video frames recorded at the same time as the M video frames included in each third video may be determined from the S video frames, and then the first target video frame in the M video frames and the second target video frame in the M video frames included in each third video are synthesized to obtain M first fusion video frames.

The second possible scenario:

when S is equal to M, the number of frames of the video frames included in the first video is equal to the number of frames of the video frames included in each third video, that is, the first target video frame is one video frame of the S video frames, and the second target video frame is one video frame of the M video frames included in each third video.

Alternatively, in the case that the input parameter includes an input trajectory, the above S103 may be specifically implemented by the following S103A and S103B.

S103A, the video playing device responds to the first input, and determines a first fusion position of the second target video frame in the first target video frame in each third video according to the input track.

Optionally, the input track may include a track direction and a track shape.

It should be noted that, when the first target video frame is a first video frame recorded at a first time in the first video, the first fusion position is a composition position of P target moving objects in the first target video frame, that is, the first fusion position at this time is a starting position of the P target moving objects. And then sequentially distributing first blending positions of the second target video frame in other video frames except the first video frame in the first video according to the track direction and the track shape of the input track.

S103B, the video playing apparatus synthesizes the first target video frame and the second target video frame in each third video according to the first fusion position, and obtains M first fusion video frames.

It is understood that the blend positions in adjacent ones of the M first blended video frames are connected to form a blend track that is consistent with the input track of the first input. In this way, the motion trajectory of each target moving object in the second video coincides with the input trajectory of the first input.

Illustratively, in conjunction with the description of fig. 2 above, the handset displays a first target video frame, as shown in fig. 3 (a). Wherein the first target video frame comprises a moving object: a human. Since the track direction of the finger sliding track is upward and the track shape is a longitudinal line, according to the sliding track, the first fusion of 5 second target video frames shown in (b) in fig. 3 is determined as a position, so that according to the first fusion position, the 5 second target video frames are respectively synthesized with one first target video frame recorded at the same time in sequence to obtain 5 first fusion video frames. In this way, the fusion trajectory formed by the fusion positions of the M first fusion video frames is as shown in (b) of fig. 3, so that the 5 first fusion video frames are synthesized, and the moving object in the obtained second video moves straight upward according to the sliding trajectory.

Illustratively, in conjunction with the description of fig. 2 above, the handset displays a first target video frame, as shown in fig. 4 (a). Wherein the first target video frame comprises a moving object: a human. Since the track direction of the finger sliding track is rightward and the track shape is an arc, according to the sliding track, the first fusion positions of 5 second target video frames shown in (b) in fig. 4 are determined, so that according to the first fusion positions, the 5 second target video frames are respectively synthesized with one first target video frame recorded at the same time in sequence, and 5 first fusion video frames are obtained. In this way, the fusion trajectory formed by the M first fused video frames is as shown in (b) in fig. 4, so that the 5 first fused video frames are synthesized, and the moving object in the obtained second video moves in an arc to the right according to the sliding trajectory.

S104, the video playing device synthesizes the M first fusion video frames according to the input parameters to obtain a second video.

Optionally, in the case that the input parameter includes an input strength, the step S104 may be specifically implemented by the following steps S104A and S104B.

S104A, the video playing device determines a first time interval between two adjacent first fusion video frames in the M first fusion video frames according to the input force.

Optionally, when the first input is a sliding input, the electronic device may determine an input strength according to a touch strength of a user on a screen of the electronic device; or determining the input force according to the line thickness of the input track.

Further, when the input force is determined according to the line thickness of the input track, the thicker the line of the input track is, the larger the input force is; conversely, the thinner the line of the input track, the smaller the input force.

It should be noted that, in the embodiment of the present application, when the input strength is larger, the first time interval is larger; the first time interval is smaller when the input force is smaller.

S104B, the video playing apparatus synthesizes the M first fused video frames according to the first time interval, to obtain a second video.

It should be noted that, in the embodiment of the present application, when the first time interval is smaller, the number of frames of the first fusion video frame required for video synthesis in unit time is greater, and then the motion speed of each target moving object in the obtained second video is smaller, that is, an effect of slowing down motion occurs in each target moving object in the second video; when the first time interval is larger, the number of frames of the first fusion video frame required for video synthesis in unit time is smaller, and the motion speed of each target motion object in the obtained second video is faster, that is, each target motion object in the second video has an effect of acceleration action. Therefore, the user can trigger and adjust the movement speed of the target moving object in the video according to actual requirements.

Illustratively, as shown in fig. 5 (a), in conjunction with the above-mentioned description of fig. 4, since the trajectory line of the finger sliding trajectory shown in fig. 5 (a) is thicker than the trajectory line of the finger sliding trajectory shown in fig. 4 (a), the input force of the first input is larger, and thus the number of frames of the second target video frames that need to be synthesized in a unit time is reduced from 5 second target video frames shown in fig. 4 (b) to 3 second target video frames shown in fig. 5 (b), and the 3 second target video frames are sequentially synthesized with one first target video frame recorded at the same time, respectively, to obtain 3 first fused video frames. In this way, the fusion track formed by the 3 first fusion video frames is as shown in (b) in fig. 5, so that the 3 first fusion video frames are synthesized, and the motion speed of the motion object in the obtained second video is faster than that of the target motion object in fig. 3.

Second possible implementation

Optionally, P < N; after S101 and before S102, the video playing method provided in the embodiment of the present application may further include S105 to S107.

S105, the video playing device responds to the first input, and synthesizes a third target video frame of the first video and a fourth target video frame of each third video in the P third videos according to the input parameters to obtain M second fusion video frames.

And the third target video frame and the fourth target video frame are video frames recorded at the same time. The P third videos are videos corresponding to the P target moving objects.

Optionally, the input parameters may include at least one of: inputting track and inputting force.

Optionally, the third target video frame is any one video frame in the first video, and the fourth target video frame is any one video frame in each of P third videos.

Optionally, for the above description of obtaining the M second fusion video frames, reference may be made to the detailed description related to the M first fusion video frames in the above embodiment, and details of this description are not repeated in this embodiment.

Optionally, in the case that P < N, before the above S101, the video playing method provided in this embodiment of the present application may further include: the video playing device receives user input of P target moving objects in N target moving objects included in the first video; in response to the input, the P target moving objects are selected. In this way, when the user is triggered by the first input, the input parameters of the first input may only trigger the adjustment of the motion parameters of the P target moving objects.

S106, the video playing device synthesizes each second fusion video frame and (N-P) fifth target video frames respectively to obtain M third fusion video frames.

Each fifth target video frame is a video frame of one of (N-P) third videos, and each fifth target video frame and the third target video frame are video frames recorded at the same time.

Alternatively, S106 may be specifically implemented by S106A and S106B described below.

S106, 106A, the video playing device determines second fusion positions of the (N-P) fifth target video frames in each second fusion video frame according to the composition positions of the (N-P) target moving objects in the third target video frames.

Specifically, the (N-P) composition positions of the (N-P) target moving objects in the third target video frame are obtained, and each composition position is used as the second fusion position of one fifth target video frame in the (N-P) fifth target video frames in each second fusion video frame.

S106B, the video playing apparatus synthesizes the (N-P) fifth target video frames and each second fused video frame according to the second fused position, to obtain M third fused video frames.

It should be noted that, since the second fusion positions of the (N-P) fifth target video frames in each second fusion video frame are determined by the composition positions of the (N-P) target moving objects in the third target video frames, the second fusion positions in each third fusion video frame of the M third fusion video frames are connected to form a fusion track, and the fusion track is consistent with the motion tracks (e.g., track shape and track direction) of the (N-P) target moving objects in the first video. Namely, the motion tracks of the (N-P) target moving objects are not changed.

And S107, the video playing device synthesizes the M third fusion video frames to obtain a second video.

Alternatively, S107 may be specifically implemented by S107A described below.

S107A, the video playing device synthesizes M third fusion video frames according to the second time interval to obtain a second video.

Wherein the second time interval is a time interval of any two video frames in the first video.

It should be noted that, since the time interval of any two video frames in the first video is determined, when the second video is obtained by synthesizing M third fused video frames according to the second time interval, the motion speed of (N-P) target moving objects in the second video is not changed, that is, the motion speed of (N-P) target moving objects in the second video is consistent with the motion speed of (N-P) target moving objects in the first video. Namely, the movement speeds of the (N-P) target moving objects are not changed.

It can be understood that when N is greater than 1, the input trajectory of the first input indicates that it is desired to adjust the motion trajectories of the P target moving objects to be consistent with the input trajectory. The electronic equipment obtains the fusion position where the video frames recorded at the same time in the first video and the N third videos are synthesized and the motion speed of the P target motion objects in the fusion video by obtaining the input track and the input force of the first input, so that the motion objects with different original motion tracks and motion speeds keep the same motion track and motion speed under the motion track appointed by the fingers of the user, and the moving objects with the same original motion track can also move along different motion tracks under the triggering of the user, thereby greatly increasing the interest of video playing.

The embodiment of the present application provides a video playing method, when a video including at least one moving object is being played, since the video is used to trigger playing of a fused video composed of the video and another video including each moving object through an input to the video, a motion parameter of a certain moving object in the at least one moving object changes according to the input parameter of the input, that is, a user can freely change a motion parameter (for example, a motion speed and/or a motion track) of a moving object in a played video according to his/her own will. Therefore, the flexibility of the video playing mode is greatly improved, and the video playing mode is more humanized.

Optionally, in the case that the first video and the N third videos are videos recorded by the electronic device, before the step S101, the video playing method provided in the embodiment of the present application may further include the following steps S108 and S109.

And S108, the video playing device receives a third input.

Optionally, the third input may be touch input, gesture input, voice input, or the like. For example, the touch input is a click input of a target control by a user, and the target control is used for triggering recording of a video. Of course, the third input may also be other possible inputs, which is not limited in this embodiment of the application.

Optionally, before the user triggers the camera of the electronic device to record the video, the user needs to trigger the electronic device to run the camera application program. Thus, before the step S108, the video playing method provided in the embodiment of the present application may further include: the video playing device receives input of a user to a camera application icon; and responding to the input, running the camera application program indicated by the camera application icon, and starting the first camera and the N second cameras of the electronic equipment. In this way, the images of the target moving object can be acquired by the first camera and the N second cameras.

And S109, the video playing device responds to the third input, controls the first camera of the electronic equipment to record the first video, and controls each second camera of the N second cameras of the electronic equipment to record a third video respectively.

And a third video is a video recorded in the process of tracking the motion of a target moving object by a second camera in the process of recording the first video.

For example, the first camera may be a main camera and the second camera may be a large-angle periscope or a rotatable camera.

It should be noted that when N is greater than 1, the N second cameras may be the same type of camera or different types of cameras. The method is determined according to actual use conditions, and the method is not limited in the embodiment of the application.

As an example, the video playing device is a mobile phone, and N is 1. As shown in fig. 6 (a), the cell phone displays a preview interface. If the user wants to trigger the electronic device to record a video, the user can click on control 01 in the preview interface. After the cell phone receives the click input, the cell phone may control the main camera to record the first video and control the periscope to record a third video in response to the click input, as shown in (b) of fig. 6.

It should be noted that, since a third video is a video recorded during the process of recording the first video and tracking the motion of a target moving object by using a second camera, the motion details of a target moving object included in each video frame of a third video are clearer.

Further, since the field angle range of the first camera is large, each video frame of the first video includes a large-area background image in addition to the images of the N target moving objects, so that the moving states of the N target moving objects are not clear enough. Therefore, the first video and the N third videos are synthesized to obtain a second video, and the dynamic process image of the moving object in the second video is clearer.

According to the video playing method provided by the embodiment of the application, the user can trigger the first camera of the electronic equipment to record the first video through input and control each second camera of the N second cameras of the electronic equipment to record the third video respectively, so that the electronic equipment can store a plurality of videos recorded by different cameras, and therefore when the user wants to view the videos, the user can view the videos recorded by each single camera according to actual needs or trigger the plurality of videos to be synthesized to obtain a fused video (namely, the second video).

It should be noted that, in the video playing method provided in the embodiment of the present application, the execution main body may be a video playing device (the video playing device is an electronic device or an external device on the electronic device), or a control module in the video playing device for executing the video playing method.
