60p to 24p super slow motion in After Effects CS3. This tutorial is so easy it's ridiculous.

Please bestow a ♥ like or leave a ✉ comment if you have questions!

Transform your 60p footage from your 7D, HVX200, Panasonic GH-1 (or what have you), and create a 120FPS effect! This is accomplished using Frame Blending and Motion Blur inside of After Effects. Keep in mind this will likely cause aliasing and artifacts in your footage since AE will be 'guessing' every other frame.

To calculate the "Stretch Factor" for After Effects (as in this tutorial), just multiply the ORIGINAL footage times 2, divided by your OUTPUT frame rate. For example:

ORIGINAL frame rate * 2 / OUTPUT * 100 = percentage of stretch. In this tutorial example,

divided by

The quotient (5) is your stretch factor multiplied by 100 (two decimal places): 500% stretch factor.

Play around with different stretch factors such as 250%, 400%, or maybe even 600%, depending on your footage. It is best to use whole numbers as mentioned. This way, After Effects can guess every other frame - not every 3 1/2 frames. The output tends to look better.

NTSC Scenario:
Project: 24p (23.976 fps)
Unedited footage: 60p (59.94 fps)
Desired output: 24p overcranked SUPER SLOW MOTION
Method: The method in the tutorial explains this scenario. (23.976 timeline, drop 60p footage in, set time stretch to 500%, export as 23.976 [24p])

Note: When I say 'forward slash for good quality' in the tutorial, I actually mean it will change the Frame Blending mode to Pixel Motion. Sorry for the confusion there.
