Hello. The 5D3 manual says I should only be getting 44 mins of 1920/24 All-I on a 32GB card....but I just recorded 2 hours of video with more space remaining, according to the timecode. Camera stopped at each 30minute point as expected. I checked and re-checked the settings...it's set to 1920/24p ALL-I. I have no idea what's going on. I just updated to 1.2.3 today.

You can use mediainfo to read the files to see what their bitrate is and compare that to what it is supposed to be?

Were you filming a white wall?
