Optical Flow/Rolling Shutter Nodes

[sollapse]

Is there a follow up on the addition of the Optical Flow/Rolling Shutter correction modules. These nodes would be extremely useful, especially the latter for proper tracking. The features have been officially listed yet tend to be put aside. I understand the practical challenges of developing and maintaining open source software, however it would be great to have an update on the progress of these features.

I am working on it on my spare time, so it may appear in any Natron version. Don't expect anything great, since there is no funding for these features, and we do not even have production-grade footage to test it on. There are third-party non-expensive commercial plugins for optical flow that work inside Natron and are thoroughly tested and validated and are probably a better option for commercial footage. For example those from RE:Vision, or the rollingshutter plugin by Foundry (which they don't seem to sell anymore for OpenFX, unfortunately). Perhaps slomovideo can be used for that purpose too, but that's out of Natron's scope.

I have found an opensource program called slomwoVideo, that seems to no longer be maintaned. Maybe it could be a useful resource for this stuff?

slowmovideo is still actively maintained (although their algorithm for interpolation is not the best one)

RollingShutter can not be purchased on any way anymore, neither OFX, AE or anywhere else. It's not part of NukeX, either. Yet if we had some MotionVectors to work with, making a RollingShutter-PyPlug wouldn't be a big of a hassle: http://unaimb.com/rollingshutter-never-left-us/
