Abstract
Disclosed are apparatuses, systems, and techniques for efficient real-time codec encoding of video files. In one embodiment, the techniques include generating a block of predicted pixels that approximates a block of source pixels of an image frame and representing a difference between the block of source pixels and the block of predicted pixels via a plurality of transformation coefficients (TCs). The techniques further include evaluating TCs using statistical data for neighborhoods of the TCs to select an action for a respective TC, including adjusting the respective TC or maintaining the respective TC.
