For some months i've been messing about with the DAIN-APP. This program uses a trained artificial intelligence neural network that takes two real frames, and 'renders' in-between frames with its neural network.

A lot of early NASA film footage was shot at 6 or 12Fps, and interpolating this to 24 or even higher does wonders to the footage. It becomes much smoother, easier to watch, and you even notice smaller details that were hidden by the previous jittering appearance.

Here are some comparisons of original framerate VS interpolated framerate:

This was interpolated from 6fps to 24:

More coming soon!
