Best rendering for mixed 24P and 720P projects?

First, the reason I want to do this is so I can shoot 24P for most stuff, but 720P for scenes with motion in them that require panning, e.g. wildlife. The target output device is a TV and/or projector via a TIVO HD. My camera can't do 1080P so that's not an option.

I've played a bit with this and panning after rendering to 1080i looks a bit less blurred on the TV than 30Pbut I'd be very interested to hear more about what the trade offs are for doing these conversions.

In Vegas you can certainly mix 24p and 30p (720p is a resolution, not a frame rate btw), but since you're not shooting a live action movie but an actual travel/wildlife video, it's best to shoot it all in 30p for consistency, edit, and export as such:

Sorry for the imprecision, I do realize 720 is a resolution. The camera (a Panasonic GH2) can shoot 24P at 1080 x 1920 which has a bit better actual resolution than the 60P 720 x 1280 which is the other progressive choice. For this camera, 1080i is actually lower actual resolution than 720P and motion looks better in the 720 60P mode anyway.

I prefer using the full 1080 resolution at 24P when possible as I don't normally do significant zooms or pans and like its better resolution and lower light capabilities. However, for wildlife 24P doesn't work as well as the 60P 720, there's too much blurring of things like wings which is bad enough at 60P. I don't mind loosing a bit of resolution in this situation, but really like the pop of the 24P particularly on a projection screen for normal slow moving scenes.

Sure, you can mix them, but it will be *jarring* to look at. If for example you setup the project as 24p and you mix 24p/60p and export as 24p, the 24p scenes will look right, and the 60p scenes will look terribly jittery, because they would have lost 36 frames in a single second.

And if you setup and export as 60p, it will be smooth at 60p, and less in 24p. This might be your best option though, since you said you won't shoot 24p for high motion scenes.

I can't get Vegas Platinum 10 to render at 1080 60P. Does that work? I always get an error "the reason for the error could not be determined".

Use MainConcept, not Sony AVC.
