>1600x900 and is a .avi file
That size description makes me think this is a screen capture, not a camera file... if it is a screen capture, what codec/software did you use?

What CODEC is INSIDE that file? http://forums.adobe.com/thread/440037
Report back with the codec details of your file, use the programs below... a screen shot works well to SHOW people what you are doing
Ok, so how do those two links help me? I want the footage to be rendered in 1280x720...
Neither of these tell my why my renders fail.
I understand you are helping me but that doesn't excuse the rudeness of just shoving two links into a reply, nothing personal.
