Thanks Alex. I had tried this earlier but still got a 23.976 file, whereas I'm trying for a 24.000 file. I did some undercranking at 22 fps and it seems that Magic Lantern conforms this to a 23.976 file? On one hand, this is great as I don't have to mess with the speeds in my NLE, but at the same time I'm trying to see if it's possible to get files with these framerates.
