Abstract

The invention discloses a video preview method and device. The method comprises the steps of storing video data and special effect data to a cache in a video editing process; in response to a video preview request, reading video data and special effect data corresponding to a target time point from the cache; and performing picture rendering according to the read video data and the special effectdata. According to the technical scheme, the situation that the data of the picture at the target time point is obtained again for rendering again is avoided, consumption of resource reading and rendering is reduced, the preview speed is increased, expenditure is saved, and the efficiency is higher.

Description

technical field [0001] The invention relates to the technical field of video processing, in particular to a video preview method and device. Background technique [0002] When the video is playing, it is driven by data frames, and during the video editing process, the video is in a paused state. Therefore, if the user drags the progress bar or edits the current screen, the screen needs to be re-rendered. At present, due to the lack of data frame drivers, when it is necessary to render a picture at a time point, it is necessary to obtain the video data and special effect data corresponding to the time point, and process them all once, which takes a long time, is inefficient, and consumes a lot of resources. Contents of the invention [0003] In view of the above problems, the present invention is proposed to provide a video preview method and device that overcome the above problems or at least partially solve the above problems. [0004] According to one aspect of the pres...
