[INFO] Feature, add/update rife frame interpolation

[Brutoloco]

The crash error doesn't always appear and it takes me a while to reproduce the problem, because the crash occurs at the end of a video, and it takes like more than an hour, I'm using the computer, with other tasks most of the time, as soon as I find for now, I'll try to reproduce the error and upload the log.

I'm sorry for the inconvenience.

The other error, aboyt sync issue, seems doing it always when I use fractional interpolation with many decimals on a 23.976, but I have to test others sources.
