Abstract

Certain aspects of a method and system for adaptive preprocessing for an encoder may comprise filtering received video data using one or more spatial and/or temporal filtering parameters. The spatial and/or temporal filtering parameters may be adaptively updated to achieve a targeted bitrate based on statistical analysis of received video data and encoder feedback. The statistical analysis of received video data may comprise analysis of statistical inputs such as an encoding standard of the received video data, an average quantization factor, an input noise level, an average picture luma level, a motion vectors histogram, and a content type detection of the received video data. The spatial filtering parameters may be adaptively updated during an I frame of the received video data and the temporal filtering parameters may be adaptively updated per frame of the received video data.
