--ignore-errors -f "(mp4)[height>=720][height<=1080][fps>=30]+bestaudio[ext=m4a]" -f bestvideo+bestaudio --download-archive "C:\Users\user\OneDrive\Youtube-DL\DownloadArchives\FunhausArchive.txt" --reject-title "podcast" -o "c:/temp/Funhaus/%(upload_date)s - %(title)s - [%(id)s].%(ext)s" #-o "G:/youtube/%(uploader)s/%(upload_date)s - %(title)s - [%(id)s].%(ext)s" --recode-video mp4 --ffmpeg-location 'C:/Users/user/OneDrive/Youtube-DL/ffmpeg/bin/ffmpeg.exe' --console-title --add-metadata --mark-watched --verbose --postprocessor-args "-hwaccel qsv -c:v h264_qsv" --exec 'move {} g:/funhaus/'

The above doesnt seem to work, it works fine when i comment out --postprocessor-args. What's the correct syntax to use quicksync to speed up ffmpeg?
