I just upgraded from a Canon 60D to a 5D3. We actually got decent video with the 60D but I wanted a full frame and it was time to get a 5D. We flew it today for the first time and when the recording reached the 4 Gig limit it split the clip at that point, (6 minutes) and kept recording. My settings were 1080p 30fps, on ALL-1. This makes a huge file size so you reach the 4 Gig limit quickly. I have read that ALL-1 is better for motion than IPB, and is also better quality so I used it. Now I am wondering if anyone has tested both ALL-1 and IPB and noticed any differences in their aerial video as well as in editing each one. I searched but didn't really see to much on this subject. When I used the 60D I shot on 1080p/30 and could easily edit in FCPX, or hand the files over to the client right off the card. Now I'm thinking that ALL-1 maybe is too big of a file to deal with, but IPB is inferior. Any thoughts?
