Abstract
An apparatus to facilitate encoding video data is disclosed. The apparatus includes rendering logic to render graphics video data as frame data, fade extractor logic to extract fade effects data to be applied to the frame data to generate frame auxiliary metadata comprising the fade effects data, weighted prediction logic to receive the frame data and the auxiliary metadata and compute one or more weighted predictions on the frame data at one or more frame sequences indicated in the fade effects data and encoding logic to encode the frame data based on the one or more weighted predictions.
