550D framerate information
Created originally on Bitbucket by Anonymous
First of all; one thing I have noticed is 24p (in fullHD mode), does not record at 24fps, it records at 23.976fps, which is normal for NTSC (because you can convert it to "30"fps with a 3:2 pulldown). But the problem is that the PAL 24p mode is also 23.976fps, which is absolutely useless for PAL uses, 24p in PAL should be 24fps.
So I wrote to Canon about this problem and the response I got was as follows: I have passed this onto our next level support. However, the reply we have got back is that it is a camera specification. There is no firmware update or anything that will change the cameras specifications.
I noticed that somebody had working 20fps in one of the mode, but I'm not sure if they realised that it was still 30fps being played back at 20fps because the audio only went for 2/3 of the video and the video was slow.
I know there have been requests for other frame rates, particularly higher frame rates which have been dismissed, but I do wonder if magic lantern could actually alter the 24p mode to an actual 24fps without just changing the flag which speeds up the end recorded video.
