As per topic. Thx!
depending on your resolution and framerate. because the main reason for the filesize are the raw-frames, other block-types are negligible for a rough calculation.
xres * yres * 14bit * framerate = bitrate/second
example:
1920 * 1080 * 14bit * 24 frames/second = 696729600 bits/s -> ~70MB/second (add 10% for other data, reserve, overhead, whatever)
answering your question:
32GB -> 32.000 Mbyte card / 77 = ~415 seconds or ~ 6 minutes 55 seconds

You're awesome chmee.
I have the Canon 7D and I get about 15 minutes of raw video for each of my 64GB cards shooting at 1728 x 972 (max continuous resolution at 23.976). Using Baldand's encoder, I can convert the raw to prores and I get about 1GB per minute of raw video after converting. MLRAWVIEWER: http://www.magiclantern.fm/forum/index.php?topic=9560.0
But chmee's answer is better.
