What is it? I just downloaded the Sonic Unleashed E3 2008 trailer in mov, and it had H264 video and IN24 audio.

A quick google brought results relating to 24bit.. e.g. "In 24 bit..."... how do I decode this?

oh, what o_o It didn't look right to me... everything I tested it with said the bitrate is 384Kbps, but doesn't the bitrate grow exponentially with the bit depth? e.g. bitrate = bit depth * 96... for example, 16bit is 1536kbps, so shouldn't this say 2304kbps?

If you click on the link I provided and then click on the "QT" live link, you'll find plenty of technical information...
