Which VideoBlocks motion background format to download?

[Peru]

I just joined VideoBlocks. I want to download some motion backgrounds to use in Premiere Pro CS5.5, but don't know how to decide which format to download:

HD 1920x1080 @ 29.97fps
MP4 H.264 (.mp4)
21.42 MB

or

High Definition 1920x1080, 29.97fps, Photo-JPEG QuickTime file.
294.46 MB

are options for one file.


HD 1920x1080 @ 29.97fps
MP4 H.264 (.mp4)
124.93 MB

or

Format: HD 1920x1080p, 30fps, H.264 QuickTime format
124.92 MB

are options for another file.

How do I decide which to use?

MP4 and Quicktime (MOV) are container formats and are fairly similar. What matters more are the codecs used for the contents. MP4 typically uses MPEG-4 AVC / H.264 for video and AAC for audio. Quicktime is typically much looser. For example, in the two examples you listed, one is using Photo-JPEG and the other is using H.264. If the MP4 and Quicktime files are both using H.264, they will be almost identical assuming they were compressed with the same profile and bitrate. You can generally use either file type, but try to stick to H.264 rather than Photo-JPEG unless you have a reason to do so. Quicktime is generally more associated with Mac and MP4 is more PC / Unix.
