It should be noted that, the second preset area of the video browsing interface may include a video thumbnail displayed on the first preset area of the video recording interface.
According to the method and the device for acquiring the video images, the acquired video images of each frame and the identification information of the camera used for acquiring the video images of each frame are stored in an associated mode in the video image acquisition process, so that the identification information associated with the video images of each frame can be guaranteed to accurately reflect the camera used for acquiring the video images, and the identification information associated with the video images of each frame can be acquired conveniently.
Optionally, the identification information includes watermarks, each of the N cameras is associated with a watermark, and watermarks associated with different cameras are different;
the step of storing the identification information of each frame of video image and the camera used for collecting each frame of video image in an associated mode comprises the following steps:
and storing the watermark associated with each frame of video image and the camera used for acquiring each frame of video image.
In this embodiment, at least one watermark may be set for each of N cameras in advance, where different cameras are associated with different watermarks, for example, as shown in fig. 3, the N cameras include a WIDE-angle camera, a main camera, and a tele camera, where three watermarks, that is, WIDE1, WIDE2, and WIDE3, are set for the WIDE-angle camera, three watermarks, that is, MASTER1, MASTER2, and MASTER3, and three watermarks, that is, ULTRA1, ULTRA2, and ULTRA3, are set for the tele camera. In this way, the video image shot by the camera and the watermark associated with the camera can be stored in a correlated manner in the process of shooting by one of the N cameras.
According to the video processing method and device, watermarks are associated with each of the N cameras in advance, different cameras are associated with different watermarks, in the process of collecting video images through the N cameras, each frame of video image is associated with the watermark associated with the camera used for collecting each frame of video image, and therefore video clips shot by the cameras can be intuitively and rapidly distinguished based on the watermarks associated with the video images of each frame of video in the video.
Optionally, the video recording interface includes a first control;
in the process of acquiring video images through the N cameras, the method further comprises the following steps:
displaying a first watermark on a first video image displayed on the video recording interface, wherein the first video image is acquired by a first camera, and the first watermark is a watermark associated with the first camera;
in case of receiving a second input of a first indication identifier on the first control by a user, responding to the second input, moving the first indication identifier to a target position, updating the first video image into a second video image, and displaying a second watermark on the second video image;
The second video image is a video image collected by a second camera, the second watermark is a watermark associated with the second camera, and the second camera is a camera associated with a target zoom multiple indicated by the target position.
In an embodiment of the present application, the first control may include, but is not limited to, a zoom bar. The first indication marks are in one-to-one correspondence with the zoom multiples on the zoom bar. The second input may include, but is not limited to, a drag input, a slide input, and the like. The above-described target zoom factor may also be referred to as a target focal length.
The following description is made by taking an example in which N cameras include a wide-angle camera, a main camera, and a telephoto camera: before capturing video, a video watermarking switch of the camera may be turned on to turn on the video watermarking function. Smooth switching between different cameras can be achieved by sliding the zoom bar during video acquisition, for example, as shown in fig. 4a to 4c, dragging the zoom bar 30 to the left to a magnification of less than 1×, opening the wide angle, dragging the zoom bar to the right to a magnification of greater than 5×, and opening the tele.
The watermark matching method comprises the steps that after a sliding zoom bar is switched to different cameras in the video acquisition process, the watermark of the corresponding camera is automatically matched. For example, in the case of capturing a video image by a main camera, displaying the video image captured by the main camera on a video interface, and displaying the watermark associated with the main camera on the video image captured by the main camera, as shown in fig. 4a, displaying the watermark 41 associated with the main camera, that is, the Master watermark, on the video image captured by the main camera displayed on the video interface; under the condition that video images are acquired through the wide-angle camera, displaying the video images acquired by the wide-angle camera on a video recording interface, displaying watermarks related to the wide-angle camera on the video images acquired by the wide-angle camera, and displaying watermarks 42 related to the wide-angle camera, namely a wide watermark, on the video images acquired by the wide-angle camera displayed on the video recording interface as shown in fig. 4 b; in the case of capturing a video image by a tele camera, displaying the video image captured by the tele camera on a video recording interface, and displaying the watermark associated with the tele camera on the video image captured by the tele camera, as shown in fig. 4c, displaying the watermark 43 associated with the tele camera, that is, the ultra watermark on the video image captured by the tele camera displayed on the video recording interface.
It should be noted that, the video image displayed on the video interface may be an acquired video image or a video image for video encoding; the small-size image corresponding to the collected video image may be an image with a size smaller than that of the collected video image, for example, an image obtained by reducing the collected video image by a preset multiple. In the case that the video image displayed on the video recording interface is a small-size image corresponding to the collected video image, the embodiment of the application can store each collected frame of video image, the small-size image corresponding to each frame of video image and the watermark associated with the camera used for collecting each frame of video image in an associated manner.
In the process of acquiring video images through the N cameras, the zoom multiple can be adjusted to switch different cameras for video image acquisition, the watermarks of the cameras after switching can be adaptively matched and displayed on the acquired video images, the operation is convenient, and a user can intuitively check the cameras used for acquiring the video images.
Optionally, different cameras in the N cameras correspond to different zoom multiple ranges, and each camera in the N cameras acquires a video image in the corresponding zoom multiple range;
The step of storing the identification information of each frame of video image and the camera used for collecting each frame of video image in an associated mode comprises the following steps:
and storing each frame of video image and the zoom multiple identifications corresponding to the zoom multiple used by each frame of video image in an associated mode.
In this embodiment of the present application, different cameras among the N cameras correspond to different zoom multiple ranges, for example, the N cameras include a wide-angle camera, a main camera, and a tele camera, where the zoom multiple range corresponding to the wide-angle camera is less than 1 time, that is, less than 1×, the zoom multiple range corresponding to the main camera is 1 time to 5 times, that is, 1×to5×, and the zoom multiple range corresponding to the tele camera is greater than 5 times, that is, more than 5×. Alternatively, in the process of capturing video by the N cameras, different cameras may be switched by sliding the zoom bar to perform video image capturing, for example, as shown in fig. 4a to 4 c.
And the zoom multiple identifiers corresponding to the zoom multiple are used for identifying the zoom multiple. In practical application, under the condition that each frame of video image and the zoom multiple identification corresponding to the zoom multiple used by each frame of video image are stored in an associated mode, based on the zoom multiple identification associated with each frame of video image, the zoom multiple used by each frame of video image can be determined, and the camera used by each frame of video image can be determined based on the zoom multiple range to which the zoom multiple used by each frame of video image belongs.
In this embodiment of the present application, different cameras among the N cameras correspond different zoom multiple ranges, and each camera among the N cameras gathers video images in the corresponding zoom multiple range, and in the process of gathering video images through the N cameras, each frame of video image that gathers and the zoom multiple sign that corresponds that the zoom multiple that gathers each frame of video image used are associated and stored, so based on the zoom multiple sign that each frame of video image is associated in the video, not only can be quick distinguish the video clip that each camera took, but also can handle from the video clip that the different zoom multiple corresponds of zoom multiple dimension screening.

For example, as shown in fig. 5a, the second control is a watermark selection control 51, and the watermark associated with each frame of video image that is played is displayed on the watermark selection control 51. It should be noted that, during the process of playing the target video, playing the target video may be paused to view the watermark associated with the video image of the current frame displayed on the watermark selection control 51.
In another embodiment, if the identification information associated with the video image is a zoom multiple identification, the zoom multiple identification associated with each frame of video image that is played may be displayed on the second control in real time during the process of playing the target video. For example, as shown in fig. 5b, the second control is a playing progress bar 52, and the zoom multiple identifier 62 associated with each frame of video image played is displayed on the playing progress bar 52.
In another embodiment, if the identification information associated with the video image includes a zoom multiple identification and a camera identification, the zoom multiple identification and the camera identification associated with each frame of video image that is played may be displayed on the second control in real time during the process of playing the target video.
