>Premiere Pro 5.0
Current is 5.0.3 for Windows, which includes several fixes and enhancesments... you need to update
All Adobe updates start here and select product, read to see if you need to install updates in number order, or if the updates are cumulative for the individual product http://www.adobe.com/downloads/updates/
Also, See 2nd post for picture of NEW ITEM process http://forums.adobe.com/thread/872666 to be sure your project sequence matches your video file
It's entirely possible the clip actually is 1440 x 1080, which gets displayed as 1920 x 1080 because it uses a Pixel Aspect Ratio of 1.33 rather than square. (1.33 x 1440 = 1920)
Thank you for taking the time to respond to this question? The Programs from AVS4YOU report the frame as 1920 x 1080. From the Wikipedia Article on H.264 it seems there is no 1440 x 1080 specification. Is the frame width reported in the file or calculated? How does Windows 7 know enough to report this data? Is the H.264 Codec for Premier 5.5 different then toe one for 5.0.3?
The codec is the same. I don't know what quote you're looking at, but to the best of my knowledge there aren't any resolution restrictions for H.264 encoding.
