Abstract
The various implementations described herein include methods and systems for coding video. In one aspect, a method includes receiving video data including a current image frame having a sample with a first color component and a second color component. The method further includes obtaining a first clipping range for pixel values of the first color component in the sample based on a syntax element value in the received video data and deriving a second clipping range for pixel values of the second color component in the sample based on the first clipping range. The method further includes in response to a pixel value of the second color component exceeding the second clipping range, restricting the pixel value to a minimum value or a maximum value corresponding to the second clipping range. The method further includes reconstructing the current non-monochrome image frame using the restricted pixel value for the sample.
