Official Sony Pictures Blu-ray launch list updated {Engadget HD}
Jun 16th 2006 2:02PM Those HD broadcast grabs will probably look quite different from the material played off a Blu-Ray disc. The specs for ATSC HDTV have a much smaller peak bitrate, and the compression process (multi-pass interactive) used in authoring discs is quite different from the approach taken for broadcast. Time will tell!
Definition of HDTV: here we go again {Engadget HD}
Mar 13th 2006 6:23AM Don't forget about temporal resolution. Remember 35mm film is 4k x 4k pixels (or more) but it still flickers due to the 24fps frame rate.
Rumors of MPEG-2's death greatly exaggerated? Digigami does HD on a regular DVD {Engadget HD}
Dec 26th 2005 9:02AM MPEG-2 VBR at SD DVD bitrates has been verified by Sagittaire at Doom9.org. He re-encoded an HD trailer from the Apple HD site down to MPEG-2 VBR 3.8 mbits/s avg (SD DVD is between 3 and 8 mbits/s), and everyone agrees it looks great. The stream is very nearly constant Q (around 6.5), and Superbit DVDs, which IMHO, are the best encoded MPEG-2 around, are semi-constant Q between 2-6. Most macroblock artifacting occurs in 10 and up.

At the same time, the H.264 pros over there showed me some very low bitrate samples that looked excellent. However, the only encoder to support all professional coding features, including interlacing, is Ateme, at $9000K or "unobtanium" depending on who you ask. So I am looking forward to comparing as Nero did at CES, which is high-bitrate, HD.
At this point, I am a believer in both codecs for different reasons.
