Abstract
A method of video decoding includes reconstructing a coded picture including at least a first sample. The coded picture is associated with a Supplemental Enhancement Information (SEI) message for a film grain synthesis process to be applied to the reconstructed picture. The SEI message for the film grain synthesis process includes a syntax element indicating that alpha channel information is used in the film grain synthesis process. The method of video decoding includes applying the film grain synthesis process to the first sample based at least on the alpha channel information.
