I did some initial tests blowing up a suitable 60 fps sample (person
running) to 240 fps.

- mode linear gave the same results as with the framerate filter (expected)
- mode gmc gave me a green screen throughout the video (I got no warning or
error, though)
- mode obmc looked very promising with very smooth motion in most of the
image except some strong artifacts in areas with small moving parts (no
idea if this can be improved)

The sample I used I cannot share publicly but I can make it available to
you if you like.
