Actually YFRC is not just a front end for MVTools2. YFRC uses masks to reduce artifacts in areas where interpolation failed. It works reasonably well in scenes with lots of motion. The results are not perfect but definitely better than artifacts. This method was later incorporated into the SVP modified MVTools2 (MSmoothFps). If I'm not mistaken I believe SVPflow also uses the masking technique, take a look at the mask:{} parameters. Speaking of SVP, InterFrame is truly a front end for SVPflow (a dumbed-down one at that).


@ingoldie
YFRC is only useful for doubling the frame rate. Only use it if you actually want 36fps. Other than that use MVTools2 or SVPflow to achieve the desired frame rate.

While I'm at it, let me post the latest YFRC with a tiny modification to make it compatible with the current MVTools2 variants. It requires MaskTools2 so make sure you have the latest recommended version.
