TLDR
A new video encoder proposal, H.26L, is compared against H.263 and H.264 and the trade-off possibilities between the complexity and compression performance within H.262 are presented.Abstract:
A new video encoder proposal, H.26L, is compared against H.263 and H.263+. In the comparison, both computational complexity and compression performance are analyzed. Moreover, the trade-off possibilities between the complexity and compression performance within H.26L are presented. Experimental comparisons with H.263 and H.263+ show that H.26L reduces the output bit rate about 30% with the same quality. The computation time increases about three times compared to H.263 and leads into the encoding speed of 3-6 fps for QCIF sequences on a 400 MHz Pentium III processor. Realtime operation can be achieved by applying additional, algorithmic and platform-specific optimizations.read more

Dynamic selection of motion estimation search ranges and extended motion vector ranges
TL;DR: In this article, a video encoder performs motion estimation constrained by a first search range, which results in multiple motion vectors and computes motion vector distribution information for the motion vectors.

Motion estimation/compensation for screen capture video
TL;DR: In this paper, the authors proposed a method for motion estimation and compensation for screen capture video using a distortion measure based on the count of equal/unequal pixels in two regions, sub-samples the distortion measure to speed up motion estimation, and/or uses a search pattern that prioritizes types of motion common in screen capture videos.
