Squeeze 5.1's H.264 Encoding Quality Dramatically Improved

In addition to the deinterlacing issue discussed here, Squeeze 5.0 also suffered two H.264 encoding problems. One related to very ugly key frames like those shown in Figure 1. On the left, you see the poor quality frames incident to Squeeze 5.0. Specifically, this is the first frame after a scene change, and you can see that Squeeze didn’t handle it well. Not only was this frame of poor quality, those immediately subsequent in the file were also pretty ugly as well. It took the better part of a year, but as you can see on the right, Sorenson got it fixed in version 5.1, available for downloading now at www.sorensonmedia.com/downloads.
