PS, a similar issus is happening on a co-workers machine. They are both Macs, we haven't tested PCs yet. The resolution is currently 940x529.
Sorry to bump but doesn anyone have any suggestions? It's happen on PCs and Macs and seems to be a issue when dealing with screen captured video no matter what the codec or wrapper is.

Yeah, but you won't like it: don't use AE to render H.264 files.
My reason for saying this comes from a standard response I make on the Creative Cow:
Dave's Stock Answer #3:
Don't use AE to compress files for final delivery. The various compressors are there only to make quick 'n dirty files showing a project's progress to producers, clients, the kids, etc. AE is incapable of doing multipass encoding, a crucial feature that greatly improves the image quality of H.264 and MPEG-type files in particular.
Render a high-quality file from AE, and use a different application to do the compression. Popular ones are Adobe Media Encoder, Sorenson Squeeze and Apple's Compressor, which comes bundled with Final Cut Suite. Even compressing in Quicktime Pro is better than compressing in AE.

Switch to VBR, set the target bit rate to the same .45 that you want for the CBR encoding, then reset to CBR.
It could be a manifestation of the same bug that currently haunts Pr and the AME.
You can also fire-up Adobe Media encoder and import your comp to be rendered directly in it; Plus, you'll get 2 pass vbr encoding
This was the most helpful bit of info I have been able to find. The bitrate does change when doing this on a windows machine. Haven't been able to get it to work on OSX. The problem is the quality is crappy, I'll keep messing around. On doing more test I found that f4v doesn't work as VBR but will when doing CBR.
Thanks for the comment
