Film School - Filmmaking

After messing around with various ways to make super slow motion, I think I figured out the best way to make it happen.

1) Shoot 60i with a shutter speed of 1/100 or higher (1/2000 used here)

2) Convert 60i clip to 60P in TMPGENC using the filter settings "Deinterlace Always Double Framerate" (Which will make your clip 59.94fps) and "Interpolation - adjusted". This will drop some resolution, but make your clip progressive at 59.94 frames per second.

3) Create a new 23.976 Comp in After Effects. Change your preview window to 23.976. Drop the newly created 60P clip onto your After Effects timeline.

4) Apply Twixtor 4.5 to your clip. Use the following Twixtor settings: (Leave everything default except listed below)

a) Input Frame: 59.94
b) Speed: Whatever you prefer (I like 10-50%)
c) Frame Interpolation: Blend

5) Render to 24P (23.976fps) file of your choice.


You should now have a 60P clip that is interpolated to 24P with Twixtor. The slow motion should now be as smooth as it possibly can without having a camera that shoots 60P natively like the Sony EX1. You will still get some artifacting, but it wont be as bad as a clip recorded at 24 or 30fps.
