I was using Vegas Pro 8. When exporting I would using specific settings for vimeo. The results gave me a nice 1280 by 720 video.

I decided to upgrade to Windows 7 and CS4. Getting used to using CS4 and have an issue getting a proper 1280 by 720 clip. It always exports with letter boxing. I don't see anywhere during the encoding portion that allows me to change this.

Here is a link to a video edited with Vegas
Nessun Dorma // Kawasaki Kun on Vimeo

Here is one edited in CS4
Ayuri's Merry Christmas on Vimeo

While I export at 1280 by 720 in CS4 the video file shows up at the bottom download as 1280 by 980...I don't know why. Can someone help?
