Unable to encode due to lack of "Frame Rate info node"

Okay,..
Problem is:
a. the .sup files seem to use multiple bitmaps for a single descriptor which SupTile doesn't support.
b. SupTiles development was abandoned, since the author lost the source code (and it was closed source)
c. there is no alternative Avisynth filter for SupTile

Solution:
Using Vapoursynth, the subtitles can be embedded without a problem.

-> Since there are no alternatives for the Avisynth SupTile filter, embedding your subtitles with Avisynth directly isn't possible.
