Video compositing method and device

Abstract

The embodiment of the invention discloses a video compositing method and device. The video compositing method comprises the steps of receiving a video compositing request of a user; according to the video compositing request, determining media materials required by video compositing, display periods, corresponding to the media materials, in an expected compositing result, render effects corresponding to the media materials, and render periods corresponding to the render effects; according to determining results, generating time domain distribution information used for video compositing, wherein time domain distribution situations of the media materials in the expected compositing result, and time domain distribution situations of the render effects corresponding to the media materials in the expected compositing result are recorded in the distribution information; respectively decoding the media materials, and conducting compositing on decoding results of the medial materials according to the time domain distribution information. Thus, in a video, image and audio compositing process, corresponding effects can be added at the same time, time for video compositing is shortened, and user experience is promoted.

Description

technical field [0001] The present invention relates to the technical field of video processing, in particular to a video synthesis method and device. Background technique [0002] In this era of micro-shooting, people often use mobile terminals such as mobile phones and tablet computers to take videos, pictures or record audio to record the details of work and life. People can also install software with media material editing functions in the mobile terminal to synthesize the captured video, pictures and recorded audio into a dynamic video with sound, and can also add various special effects to the synthesized video. [0003] However, in the media material editing software in the prior art, when synthesizing video, pictures and audio and adding special effects, it needs to be carried out separately, that is, first video, picture and audio are synthesized, and then the corresponding video is added to the synthesized video. or add corresponding special effects to the video, ...

Problems solved by technology

[0003] However, in the media material editing software in the prior art, when synthesizing video, pictures and audio and adding special effects, it needs to be carried out separately, that is, first video, picture and audio are synthesized, and then the corresponding video is added to the synthesized video. special effects, or add corresponding special effects to the video, picture and audio respectively, and then synthesize the video, picture and audio after adding the special effects. The editing process is cumbersome, takes a long time, and the user experience is poor.
