I don’t know anything about Staxrip, but this might work:
Staxrip-Framerate AssumeFps
Like Frankb said. Just run:
AssumeFPS(24000,1001,true)
That will slow your video down. You need to make a call to sync_audio to also shift the audio. I didn’t do this because I decided to just use NTSC audio. The “True” command tells the filter to synchronize and slow the audio by 4%.
If you make a clip available to me, I’ll verify your audio is properly slowed. Emissary or Sacrifice of Angels preferred, because I have those ripped already and I know you have Emissary finished.
Also, Frank: You are absolutely correct re: the precise amount of slowdown, but AssumeFPS handles the calculation after the decimal correctly, as far as I know. Animaxx shouldn’t need to set anything beyond “24000,1001,true”
