An interpolation method that might be useful.

This is an interesting thing I stumbled upon when working with SVP4 and DmitriRender.

When we force both FFDShow and DmitriRender in the MPC player, the video is interpolated first by SVP to the specified number of frames, and then by DmitriRender to the screen refresh rate. (FFDShow comes ahead of DmitriRender)

This can make some videos look better (and some look worse, but this will be a case by case)

Maybe there are other ways. Anyone want to share what you think?
