Hi everyone.
In response to another thread in this forum asking about still image sizes for Vegas, I put together a test Veg demonstrating a couple of scenarios. Kelly Chien has been kind enough to post the introduction and the zipped project here:

The text file will display better if you download it first. There doesn't seem to be any word wrap if viewed in Internet Exploiter.
There are actually two tests in the veg file. The first compares a 720x480x0.9091 image, a 720x528x1.0 image, and a 655x480x1.0 image placed on the timeline. The test demonstrates what happens when an image is scaled to 720x480. You can draw whatever conclusion you like from it, I don't think it really favors one image size over another. It does, however, show that Vegas handles a 720x528 image very cleanly.
The second part of the test takes screen shots of the 720x480 image saved as 655x480 PNG files and runs them through five generations of grabs and reimports. This test actually has a clear implication-that using such images for freeze frames introduces some image degradation. My conclusion is that you'd be better off using the clipboard tool and then saving a 720x480 frame grab with a photo editor. This would be a "best practice" for creating freeze frames.
