Abstract
Systems and techniques are described herein for processing video data. In some examples, a process is described that can include obtaining at least one block of video data and predicting one or more video samples for the at least one block. The process can include obtaining a dynamic range adjustment (DRA) syntax element from the video data. In some cases, the DRA syntax element includes an indication associated with a plurality of DRA modes for the video data. The process can include processing the one or more video samples for the at least one block using a DRA mode based on the indication of the DRA syntax element.
