@TheRealStudio13 Your issue is related with obs in a tangential manner ; it's rather an issue with ffmpeg and its dll.
It would be helpful for you to check with ffmpeg.exe binary directly if prores_aw works fine. Once a working version is found , this will set a target for updating avcodec.dll . Check the command line output of ffmpeg to know the libraries versions and report back here or on mantis.
