COMPRESSION CODECS On2 V6 – Flash VC-1 – Windows Media 9 H.264 – Quicktime/MPEG4
COMPRESSION COMPRESSION ARTIFACTS
COMPRESSION QP is a measure of how encoded each frame is, with higher values more highly compressed. In VC-1, the range is 0-31. A good rule of thumb is that QP of much below 8 looks pretty good, and QP of 8 or above...won't. Now, a live SD encode at 600 Kbps is pretty darn aggressive, so there's plenty of spots where both encodes certainly show artifacts. And quality varies a lot throughout the file as the complexity of the video goes up and down, as this is a Constant Bitrate (CBR) encode. Note the relatively low QPs near the end of the file, where the easy credits scroll comes in. But still, the modern VC-1 implementation (in red) with all of the above is dramatically better. While the old encoder (in blue) spikes all the way up to the maximum QP of 31, the new one is typically several QP lower, and maxes out at a QP of 20 instead.
