That certainly could be done. The only difficulty in this would be that Avisynth would have to simulate the upscaling of the playback device (or is it upscaled with Avisynth during the playback?).

I haven't looked at Vapoursynth so I can't tell for sure. But basically what's needed for the optimizer to work is:
1) a way to run a script programmatically from the optimizer
2) a way to specify which values the optimizer is changing in the script
3) the script has to calculate a result: quality / runtime / any other interesting value
4) the script has to write the result into a specific file

I'm very much interested in making this happen but hopefully someone who knows Vapoursynth can help me figure out the steps above.
