AVC/H.264 Importing

Folks,

I'm playing around with the Vegas v6 HD features and noticed that an AVC/H.264 encoded video file I created from HDV content from within Vegas can be dropped directly into the timeline.

If I try the same thing with a sampe AVC/H.264 content downloaded from www.quicktime.com (yes I know it is copyrighted, but I'm just playing) Vegas recognizes the audio stream of the .mov file but not the (AVC/H.264) video stream (hence if I drag and drop the media only the audio stream appears on the timeline).

Any ideas on the differences from the AVC/H.264 (Main Concept) encoded video file create in Vegas and the QuickTime H.264 content that would account for this Vegas behavior?

Thanks!

AVC is a subset of H.264. Most likely the problem file is a different flavor of H.264. What does QT player show for file properties?

The "Movie Info" provided by the QuickTime 7.0 Player for the QuickTime formatted media in question is:

Format: AAC, Stereo (LR), 44.100 kHZ, H.264, 1264x720, Millions
Movie FPS: 24.57

In Explorer tab within Vegas it correctly indicates the audio tack properties, but the Video states "stream attibutes could not be determined".

Here's a URL to the file. Click on the 720p button to download the clip, should you care to look at this directly.

Again, I know the material is copyrighted. I'm just trying to understand the "in-s and out-s" of working with HD media (in this case QuickTime file formats) in Vegas v6.

Thanks!
