I'm not really sure on how to pass ffmpeg parameters, like changing the audio, hardcoding subtitles etc.
So for example, if I want to add the following ffmpeg options to my transcodings
-vf "ass=subtitles.ass" -c:a aac -pix_fmt yuv420p
How should I add them?
Thanks in advance.
p.s.
Attachment with my current setup.
