Abstract
Techniques for coding video data are described that maintain high precision coding for low motion video content. Such techniques include determining whether a source video sequence to be coded has low motion content. When the source video sequence contains low motion content, the video sequence may be coded as a plurality of coded frames using a chain of temporal prediction references among the coded frames. Thus, a single frame in the source video sequence is coded as a plurality of frames. Because the coded frames each represent identical content, the quality of coding should improve across the plurality of frames. Optionally, the disclosed techniques may increase the resolution at which video is coded to improve precision and coding quality.
