Abstract

The invention relates to a video clipping method and device, a storage medium and electronic equipment, and aims to save the time overhead in the video cropping process and improve the video croppingefficiency. The video clipping method comprises the steps of obtaining a to-be-cropped original video and a target clipping size; determining an initial clipping frame according to the main body contents of a plurality of target video frames in the original video; determining whether each frame of picture of the original video is clipped through the same clipping frame or not according to the difference condition between the size of the clipping frame and the target clipping size and the change condition of the main body content in the plurality of target video frames; if it is determined thateach frame of picture of the original video is clipped through the same clipping frame, determining a target clipping frame capable of including the maximum main content in the original video from multiple candidate clipping frames, and the size of each candidate clipping frame being consistent with that of the initial clipping frame; and clipping the original video according to the target clipping frame.

Description

technical field [0001] The present disclosure relates to the technical field of video processing, and in particular, to a video cropping method, device, storage medium and electronic equipment. Background technique [0002] Video cropping is a technology required for scenarios where the video playback size is inconsistent with the original video. The video cropping algorithm in the related art uses the cropping frame of the target playback size to crop each video frame in the video according to the content information in the original video, and then reassembles the cropped video frames into a video. Specifically, it is necessary to plan a cropping position for each video frame through a dynamic programming optimization algorithm, perform interpolation and smoothing on the cropping position, and finally perform video coding on the cropped video frames and combine them into a new video. In the whole process, the time overhead is relatively large, which cannot satisfy the low-...
