The embodiment of the application can be applied to the scene that a user can execute input in the process of shooting the video through the electronic equipment so that the electronic equipment generates the video with rich display effect. Under the scene that the user records the video, because the electronic equipment adopts the default camera (corresponding to the fixed zoom magnification) to shoot, namely, the electronic equipment processes each acquired frame of image by adopting the zoom magnification and the recording frame rate corresponding to the default camera, the requirements of the user can not be met under certain shooting scenes (such as the scene of shooting fireworks).

Optionally, in an embodiment of the present application, the target processing parameter may include only the second zoom magnification, only the second recording frame rate, or both the second zoom magnification and the second recording frame rate. It will be appreciated that the user may perform a first input on the target object to cause the electronic device to determine a second zoom magnification, or to determine a second recording frame rate, or to determine a second zoom magnification and a second recording frame rate.

It can be understood that the target video is a video with continuously changing zoom magnification and recording frame rate, that is, the display effect of the target video presented to the user by the electronic device is not single, but the display effect meeting the user requirement is presented to the user.

In the embodiment of the application, a user can execute the first input on the magnification mark indicating the zoom magnification according to the preference requirement of the user so as to set the second zoom magnification for the video stream obtained by adopting the first zoom magnification and the first recording frame rate, so that the electronic equipment adopts the set zoom magnification to carry out video processing on the first video stream, and a video with variable zoom magnification is generated, thus, the display effect of the video is enriched, and the problem that the display effect is single due to the fact that the traditional mode only adopts the default zoom magnification and the default frame rate to carry out the whole video processing is solved, and the flexibility of recording the video by the electronic equipment is improved.

Optionally, in a second implementation, the target object includes an image stream, and the target processing parameter includes a second recording frame rate. Before the step 201, the video processing method provided in the embodiment of the present application further includes the following step 401.

Optionally, in the embodiment of the present application, after the electronic device records the first video stream, the electronic device may directly display at least two image streams in the shooting preview interface; or the electronic device may update the shooting preview interface to a second interface, where the second interface includes at least two image streams; alternatively, the electronic device may display at least two image streams after the user performs the first input on the target magnification identification. The method can be specifically determined according to actual use requirements, and the embodiment of the application is not limited.

For example, as shown in fig. 4, the electronic device may update the shooting preview interface to the second interface, and the second interface includes three image streams with different recording frame rates, namely, a first image stream 41 (recording frame rate of 30 fps), a second image stream 42 (recording frame rate of 60 fps), and a third image stream 43 (recording frame rate of 120 fps).

Step 201b, the electronic device receives a first input from a user of a target image stream of the at least two image streams.

Alternatively, in the embodiment of the present application, the target image stream may be any one of at least two image streams.

Illustratively, in connection with fig. 4, the user may enter a second image stream 42 (i.e., a target image stream) and then enter a "select frame rate complete" control 44 below the second interface to cause the electronic device to determine a recording frame rate corresponding to the second image stream 42 as a second recording frame rate.

Step 402, the electronic device determines a recording frame rate of the camera for recording the target image stream as a second recording frame rate.

Optionally, in the embodiment of the present application, each frame of video image in the target video corresponds to the same second recording frame rate.

In the embodiment of the application, a user can execute the first input on a certain image stream displayed by the electronic equipment according to the self preference requirement to set the second recording frame rate for the video stream obtained by adopting the first zooming rate and the first recording frame rate processing, so that the electronic equipment adopts the set recording frame rate to carry out video processing on the first video stream, thereby generating the video with the changed recording frame rate, thus enriching the display effect of the video, avoiding the problem that the display effect is single because the traditional mode only adopts the default zooming rate and the default frame rate to process the whole video, and further improving the flexibility of video recording of the electronic equipment.

Optionally, in the embodiment of the present application, for the first implementation manner and the second implementation manner, before step 201, the video processing method provided in the embodiment of the present application further includes the following step a and step B.

And step A, the electronic equipment receives a second input of the user.

Optionally, in the embodiment of the present application, the user may input an application icon of the camera application program, or any other identifier for indicating an entry of the camera application program, so as to trigger the electronic device to display a shooting preview interface, where in the shooting preview interface, the user may input an identifier corresponding to a certain shooting mode, so as to trigger the electronic device to record video in the mode.

Optionally, in the embodiment of the present application, a user may input a video recording mode to trigger the electronic device to control each camera in the electronic device to record video simultaneously; alternatively, the electronic device may set a mode separately, such as an image streaming mode, and the user may enter an image streaming mode to trigger the electronic device to control each camera in the electronic device to record video simultaneously. The specific determination may be determined according to actual use requirements, which is not limited in the embodiment of the present application.

For example, as shown in fig. 5, the user may input an identifier 51 corresponding to the "image stream" mode to trigger the electronic device to take a photograph in the image stream mode.

And B, the electronic equipment responds to a second input, and controls at least two cameras to record by adopting target frame rates respectively, so as to obtain at least two video streams.

Each video stream corresponds to one camera, the at least two video streams comprise first video streams, and each target frame rate is the highest recording frame rate in at least one recording frame rate corresponding to one camera.

Optionally, in the embodiment of the present application, after the user performs the second input, the electronic device may control each camera to record at least one highest recording frame rate of the at least one recording frame rates corresponding to the camera, and display, in the shooting preview interface, a video stream recorded by any one camera (for example, a default camera of the electronic device), and simultaneously cache, in a queue of a background of the electronic device, image data of the video stream recorded by each camera.

Optionally, in the embodiment of the present application, each camera corresponds to one sensor, and the electronic device may set a queue for each sensor, where each queue is used to store image data of a highest recording frame rate of one sensor, and each sensor continuously outputs image frames along the time axis at a frame interval of the highest recording frame rate (for example, 240fps is 4.16 ms). In a period, the electronic equipment grabs the image data of a certain sensor and sends the image data to a screen of the electronic equipment in real time for displaying, and meanwhile, the image data of all the sensors are respectively sent to corresponding queues for caching and used after recording is completed. In the process, the sensors with different zoom magnifications are multiplexed in a time-sharing way, namely video image frames of the sensors with different magnifications are cached in real time through a queue, so that selection interaction logic with different zoom magnifications and frame rates is provided for a user when the user shoots, and a mode of custom processing video streams is provided for the user.

As shown in fig. 6, it is assumed that the electronic device includes three cameras, namely, a camera 1, a camera 2 and a camera 3, and the camera 1 corresponds to the sensor 1, the camera 2 corresponds to the sensor 2, the camera 3 corresponds to the sensor 3, and the electronic device may capture image data of the sensor 1 and send the image data to the screen of the electronic device for display in real time, and send the image data of the sensor 1 to the queue 1 for buffering, and send the image data of the sensor 2 to the queue 2 for buffering, and send the image data of the sensor 3 to the queue 3 for buffering.

In the embodiment of the application, in the process of shooting video, different queues in the electronic equipment buffer the image data of different sensors, after the electronic equipment records at least two video streams, a user can set proper zoom magnification and recording frame rate for a first video stream in the at least two video streams so as to ensure the definition of a shot video picture and the smoothness of the change of a view angle, thereby generating the video with the zoom magnification and frame rate changed.

The above step 201 may be specifically implemented by the following step 201 c. Furthermore, before the step 202, the video processing method provided in the embodiment of the present application further includes the following step 501.

It will be appreciated that the zoom magnification curve described above is made up of a plurality of magnification nodes, each indicating a zoom magnification of the first video stream at one point in time, the zoom magnification indicated by a different magnification node being the same or different.

Optionally, in the embodiment of the present application, after the user performs the first input on the target object, the electronic device may directly display the zoom magnification curve in the shooting preview interface; alternatively, the electronic device may update the photographing preview interface to a third interface, and the third interface includes a zoom magnification curve therein.

Optionally, in an embodiment of the present application, an abscissa of the zoom magnification curve represents each time point of the first video stream, and an ordinate of the zoom magnification curve represents a zoom magnification of the first video stream.

Optionally, in the embodiment of the present application, the target multiplying power node may be one multiplying power node, and may also include multiple multiplying power nodes. It can be appreciated that the user may perform a first input on one magnification node or multiple magnification nodes in the zoom magnification curve to adjust a display position of the one magnification node or multiple magnification nodes, thereby setting a zoom magnification of a video image corresponding to the one magnification node or multiple magnification nodes.

Optionally, in the embodiment of the present application, in the case that the target magnification node includes a plurality of magnification nodes, the user may sequentially input each of the plurality of magnification nodes, so as to set zoom magnifications of video images corresponding to the plurality of magnification nodes respectively.

For example, as shown in fig. 7, after displaying the zoom magnification curve 7c, the user may input a certain magnification node 7a on the zoom magnification curve 7c to set the zoom magnification corresponding to the magnification node to 3 times, and then, the user may input a "select magnification complete" control 7b to cause the electronic device to complete setting of the zoom magnification.

Step 501, the electronic device determines a second zoom magnification according to the display position of the target magnification node.

Optionally, in the embodiment of the present application, the electronic device may determine the second zoom magnification according to the adjusted display position of the target magnification node. That is, the electronic device may determine the zoom magnification corresponding to the adjusted display position of the target magnification node as the second zoom magnification.

In the above case, in the case where the zoom magnification and the recording frame rate are set by the magnification identification and the image stream, the set second zoom magnification corresponding to each frame of video image is the same, and the second recording frame rate corresponding to each frame of video image is also the same. Compared with the situation that the zoom magnification and the recording frame rate are set through the magnification identification and the image stream, the zoom magnification and the recording frame rate are set through the zoom magnification curve and the recording frame rate curve, different second zoom magnifications and second recording frame rates can be set for each frame of video image, namely, the second zoom magnifications corresponding to each frame of video image can be the same or different, and the second recording frame rates corresponding to each frame of video image can be the same or different, so that the zoom magnification and the recording frame rate of each frame of video image can be set more flexibly.

In this way, the zoom magnification curve and the recording frame rate curve of the target multimedia file are displayed in a visual mode, so that a user can conveniently input the zoom magnification curve and the recording frame rate curve, and the second zoom magnification and the second recording frame rate are set on the basis of the target multimedia file, and the purpose of flexibly setting the zoom magnification and the recording frame rate is achieved.
