I will be creating super slow-mo effect from footage shot at 60fps on a canon 5D.
It will be of a BMX rider.
First I will conform it in cinema tools to 24p.
However following this there seems to be 5 possible ways of further slowing the footage:
1. MOTION: Motion blur blending
2. MOTION: Optical flow
3. After Effects: Timewarp
4. After Effects: Time Remapping
5. After Effects: Twixtor
I will do tests when I received the footage but as the deadline is tight I am trying to do as much prep before hand as possible. What are the general thoughts on the best method to use? Ideally I would avoid twixtor due to cost.
Motion's Optical Flow, AE's Timewarp [link] (based on The Foundry's KRONOS), AE's Time Remapping [link] (with Pixel Motion on), and RE:Vision FX's Twixtor all use similar motion estimation techniques for retiming footage. I think they'd all yield comparable results with their default settings.
Between Timewarp and Time Remapping, Timewarp offers a lot more control over the motion estimation parameters, and it allows you to separately track the foreground from the background if you can pull a key or rotoscope to create a matte. Twixtor Pro offers some features that Twixtor doesn't, like separate tracking of the foreground and background via a matte, and manual point and spline guidance.
