A quick tutorial on converting your 60p files from the Canon 7D to 24p slow motion. This is referred to as "overcranking". The method is very simple: slowing the footage down to 40% of its original speed. This creates a TRUE slowdown with no frame blending, motion estimation, or "creation" of frames.

UPDATE: Re-uploaded better quality video.
UPDATE AGAIN: Added 30p to 24p conversion method below (otherwise referred to as the 'dreamy' slo-mo effect). Also added some example links.

To calculate the speed at which your footage should be at, just divide the OUTPUT frame rate by the ORIGINAL FOOTAGE frame rate. For example:

OUTPUT frame rate / ORIGINAL FOOTAGE = percentage of slowdown. In this tutorial example,

23.976
divided by
59.94
equals
0.40

The quotient (0.40) is your percentage (40%).

NTSC Scenarios:

Project: 24p (23.976 fps)
Unedited footage: 60p (59.94 fps)
Desired output: 24p overcranked (slowmo)
Method: The method in the tutorial explains this scenario. (23.976 timeline, drop 60p footage in, set speed to 40%, export as 23.976 [24p])

Project: 24p (23.976 fps)
Unedited footage: 30p (29.97 fps)
Desired output: 24p overcranked ('Dreamy' slowmo)
Method: 23.976 timeline, drop 30p footage in, set speed to 80%, export as 23.976 (24p)
EXAMPLE(s):

Project: 30p (29.97 fps)
Unedited footage: 60p (59.94 fps)
Desired output: 30p overcranked (slowmo)
Method: 29.97 timeline, drop 60p footage in, set speed to 50%, export as 29.97 (30p)

PAL Scenarios:

Project: 25p (25.00 fps)
Unedited footage: 50p (50.00 fps)
Desired output: 25p overcranked (slowmo)
Method: 25.00 timeline, drop 50p footage in, set speed to 50%, export as 25.00 (25p)

Project: 25p (25.00 fps)
Unedited footage: 60p (59.94 fps)
Desired output: 25p overcranked (slowmo)
Method: 25.00 timeline, drop 60p footage in, set speed to 41.7%, export as 25.00 (25p)
