Abstract

The invention discloses a video adjustment method and device, computer equipment and a storage medium, and belongs to the technical field of video processing. The method comprises the following steps:encoding first video data by adopting a first ROI QP value and then decoding to obtain second video data; according to the first video data and the second video data, obtaining a first quality parameter of the second video data and a second quality parameter of a target area in the second video data; wherein the second video data satisfies a first adjustment condition; if so, adjusting the firstROI QP value according to the first quality parameter and the second quality parameter. A ROI QP value is adaptively adjusted according to the quality of the video data, so that when the code rate inthe video data is determined according to the adjusted ROI QP value, the accuracy of the code rate distributed in the video data can be ensured, and the image quality of the video data is further improved.

Description

technical field [0001] The present application relates to the technical field of video processing, and in particular to a video adjustment method, device, computer equipment and storage medium. Background technique [0002] With the rapid development of video processing technology and people's increasing requirements for video playback effects, ROI (Region Of Interest) technology is usually used to distinguish the target area and non-target area in the video data, using different The code rate encodes the target area and the non-target area separately. [0003] In the related art, when using ROI technology to encode video data, set the initial code rate, obtain the target area and non-target area of ​​each video data in the video data, and set a fixed ROI QP (Quantization Parameter, quantization parameter) for the target area. parameter) value, to determine the code rate corresponding to the target area and the code rate corresponding to the non-target area according to the...
