Problems solved by technology

Using manual operation, it is necessary to repeatedly perform operations such as slow motion and single-frame playback to find the optimal editing time point, which consumes a lot of time and energy
And often due to the tedious and repetitive work, the time point selected by manual operation is sometimes not the optimal time point

Embodiment Construction

[0089] In order to make the above objects, features and advantages of the present application more obvious and comprehensible, the present application will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0090] The inventor of this patent has found through statistical analysis many times that the time points that need to be selected during the video editing process have the following common features:

[0091] 1. Within a period of time before the time point to be selected, the audio tends to be silent;

[0092] 2. During a period of time before the time point to be selected, the background of the video is fixed;

[0093] 3. During a period of time before the time point to be selected, the foreground motion of the video is not large;

[0094] 4. Match as much as possible with the first frame of the connecting video;

[0095] 5. The time point to be selected is as close as possible to the end of the curr...

Abstract

The invention provides a method and a device for clipping a video. The method comprises the following steps of: in a video segment in an appointed time range, computing a characteristic value of a video frame according to the preset characteristic; extracting a target video frame, wherein the target video frame is the video frame of which the characteristic value is in accordance with preset conditions; and splicing the video at a time point which corresponds to the target video frame. By the invention, the video can be clipped at an optimum time point which is automatically selected, complicated manual operation is avoided, and the effectiveness of the selected time point is ensured.

Description

technical field [0001] The present application relates to the technical field of video processing, in particular to a video editing method and a video editing device. Background technique [0002] Video editing involves the processing of cutting and splicing videos at different time points, because in the process of video editing, the selection of a suitable time point is very important, but the selection of this time point can only be done manually at present. [0003] For example, if an error occurs during the recording of an excellent course, it is necessary to find a suitable time point in the video for editing. Using manual operation, it is necessary to repeatedly perform operations such as slow motion and single-frame playback to find the optimal editing time point, which consumes a lot of time and energy. And often due to the tedious and repetitive work, the time point selected by manual operation is sometimes not the optimal time point. [0004] Therefore, a techni...
