Abstract
Approaches for digital video encoding based, at least in part, on adaptive pre-filtering of the digital video. A user may select values for a plurality of video quality preference categories. An adaptive video preprocessor determines adaptive preprocessor information for the digital video, based, at least in part, on the current video complexity of the digital video and an output bit rate. The encoder encodes the digital video to produce encoded digital video using the adaptive preprocessor information. In this way, for example, the encoder may dynamically adjust how the digital video is encoded based on a selection, made by the user, regarding a stress bias video quality preference.
