Video Frame Interpolation Tool

If you are into video, one of the problems with traditional 24 fps footage is how jerky it is when horizontal panning and action shots often look like crap. A reasonably recent technique addresses that problem, between any two video frames is a gap that can be interpolated from the two frames to give an intermediate frame (or two) that changes the frame rate to much higher.

I have tested this among many other tests on good 4k@30 fps by setting the frame rate to 120 fps then slowing it down by 4 time (back to 30 fps) but the gain is super smooth slow motion with no quality loss.

Now it comes at a price, it is processor intensive and while it does not particularly overload your CPU, it is very slow as it is doing a lot of work on what appears to only be one thread so a 10 second clip gives you enough time to go and make a cup of coffee, have a cigarette or two, catch up on you sleep or whatever else you can do to idle away some time.

Speed is a lot better on 1080 footage so fixing older footage that was shot properly is viable.

To use this tool you must have a reasonably recent version of "ffmpeg" installed in the path of your computer.    :biggrin:  :skrewy:
