My editor just encoded some video (windows media, coded 9) for the web at 640 x360.
He says he encoded it at 1300 kb/sec
but when I save it from quicktime (on my mac) and then play it from QT and do command i, for info inspector is says it's at 2276 kb/sec.
But when I save it as source (it a .wmv file) and play it in window media it says right at the bottom of screen 1064 kb/sec

that's three different kb/sec!

Variable bit rate?

That and audio bit-rate is configured in there at some point too...

Wild guess:

1. Maximum video bit rate
2. Video + audio bit rate
3. Average video bit rate

Sorry, talking about kilobyte per seconds.
