Yes I got it running yesterday and now I can have it the way I want it.
in potplayer I have ffdshow raw on default profile and avisynth with a hdr profile had to disable the built-in video transform filter to get it working
The audio was going out of sync @ 48 frame so I switched to screen refresh and the audio stayed in sync.
Is there a way to get svp 4 to use more cpu power? im using an AMD R3900X and 2070 SC
