So:
MP4 1280×960, 29.97, 1.0
MOV 1920×1080, 20.97, 1.0
MTS 1920×1080, 29.97, 1.0
MTS 1440×1080, 29.97, 1.3333
I assume it’s a typo and you meant 29.97 for the Canon footage? The camera can’t do a frame rate like 20.97, but I want to eliminate the possibility that you did some kind of bad pre-conversion.
I think your best bet is a 720p 29.97 sequence(1280×720). All the 1080 footage can be scaled down nicely.
GoPro’s 1280×960 is a non-standard format. There could be a few reasons for using it, but it mostly comes down to using it as standard 720p with the ability to recompose the shot vertically if needed. In other words, you’ll need to crop some off the top and bottom for it to be a standard 16:9 viewing size.
In regard to the 1440×1080, this is a recording and not a viewing format. Premiere Pro should automatically de-squeeze the footage; you’ll be left with what is, effectively, a 1920×1080 frame.
From the 720p file you can easily upload it as-is to video sites or convert it out to a widescreen dvd format without issue.
All the footage is h.264 or a subset (AVCHD for instance) so you shouldn’t have huge playback issues at 1/2 or 1/4 resolution. If it’s a large project I would consider using an intermediate codec just because they scrub more smoothly; it could be an overall time saver.
