Video processing

An apparatus for processing video data, the apparatus comprising:

• at least one memory;
• and
• at least one processor coupled to the at least one memory and configured to:
• process video data using a video preprocessor to generate preprocessed video data, wherein the video preprocessor is trained by processing training video data using a video encoder-decoder to generate intermediate video data, processing the intermediate video data using the video preprocessor to generate output video data, determining a loss based on the output video data and the training video data, and adjusting parameters of the video preprocessor based on the loss;
• and
• process the preprocessed video data using a video encoder to generate encoded video data.

A method for training a video preprocessor, the method comprising:

• processing training video data using a video encoder-decoder to generate intermediate video data;
• processing the intermediate video data using the video preprocessor to generate output video data;
• determining a loss based on the output video data and the training video data;
• and
• adjusting parameters of the video preprocessor based on the loss, wherein the video preprocessor is configured to process video data to generate preprocessed video data and to provide the preprocessed video data to a video encoder.
