Skip Frame Interpolation Test (a.k.a. How to Only Render Half As Many Frames In Cycles)

Hey guys - just tried an experiment with a dry scene in Blender Cycles. I wanted to know if it was possible to save time by rendering at 12 frames per second, and then "create" the in-between frames later using After Effects.

Turns out, it works pretty well! Here's a quick video demonstrating the method. I know as the scene gets more complex, it probably won't work as well. But for fairly simple scenes with a slow to medium speed camera, it looks pretty solid and has a minimal amount of "streaking" (that trail-like effect you see on older consumer video cameras).

The only trick is, when you're in After Effects, make sure to use the TIMEWARP effect plugin and set the "Error Threshold" to "0" so there's no weird chunky blocks. I set it to 50% speed which then equals 24 frames per second.
