Yes, it's only the MVC decoder (FRIMSource or DGMVCSource) that can use the hardware acceleration. The rest of the avisynth script, and the x264 encoding are not accelerated. Usually, it's x264 that is the most CPU demanding, and therefore, indeed, enabling the hardware acceleration gives probably only a small improvement on the overall duration of the process.
Anyway, thanks for testing also FRIMSource with hw enabled. I'm curious to know if it works fine, like with Creature from the Black Lagoon.
