Embodiment Construction

[0085] In view of the technical problem in the prior art that the special effect preview image freezes to the user during the recording process of the special effect video, the embodiment of the present invention provides a video special effect processing method and device, and the general idea is as follows:

[0086] By performing special effect preview processing on the video frames collected during the video recording process during the video recording process, a special effect preview image for real-time presentation during the video recording process is generated; and recording special effect processing is also performed on the video frames collected during the video recording process to generate Special effect video files, so that the special effect preview image in the special recording process is separated from the special effect processing in the final saved special effect video file, and the precision of recording special effect processing is greater than that of speci...

Abstract

The invention discloses a video effect processing method and device, and is applied to the technical field of video processing. The method comprises the steps of: starting video recording; in a videorecording process, performing effect preview processing on a currently acquired video frame, and generating an effect preview image when recording; in the video recording process, displaying the effect preview image when recording in real time; performing recording effect processing on the video frame acquired in the video recording process, and generating an effect video frame, wherein the recording effect processing precision is greater than the effect preview processing precision; and, after the video recording process is ended, obtaining an effect video file composed of the effect video frame. By means of the video effect processing method and device disclosed by the invention, the effect preview image can be smoothly displayed to users in the effect video recording process; and the recorded effect video file also has good effect.

Description

technical field [0001] The present invention relates to the technical field of video processing, in particular to a video special effect processing method and device. Background technique [0002] Keying technology, simply put, is a technology that selects a certain part of an image and then synthesizes it with other image content. Specifically, image keying technology is divided into image keying and video keying, and video keying can realize the synthesis of original video and special effects, so as to form a new video with special effects. [0003] Keying technology can be applied to video recording to record special effects video. The process of recording special effects video includes two aspects: special effect video file generation and real-time special effect preview. Special effect video files are finally saved for playback and sharing. files, in order to obtain higher-quality special effects video files, it is necessary to use high-precision special effects proces...
