I'm wanting to download royalty free hd motion backgrounds from a website.

I have 2 formats to choose from:
1.) MP4 H.264 (.mp4)
2.) PhotoJPEG Quicktime (.mov)

I am currently using Vegas Pro 8 and Movie Studio 11. Would any of these formats do or will one be better than the other concerning the software that I am using.

Any help is greatly appreciated.

I bought a set that came in the .mov jpeg codec. They work fine.
If I had a choice though I would get the mp4 since they decode natively in Windows and dont need the Quicktime plugin .

Thanks Gerald. That's a great help. I noticed that the equivalent mp4 files are also quite a bit smaller in size.
