[Bf-committers] Proposal: Using optical flow to smooth Speed Control for VSE

[James Deery]

Hi,

This look interesting, I would definitely like to see it in blender. I wouldn't mind doing some work on it. If you find a good resource for an algorithm and need some help, let me know. I'd have to brush up on my vector calculus but I'm ready for a challenge.

Regards,

James
