Encoding Discussion Megathread (ffmpeg, Handbrake, AV1, etc...)

I have an issue with my ffmpeg command.
When using preset 5, I am unable to seek through the movie in jellyfin. It only shows 5 seconds in length, which extends while playing.

But when using preset 6 or higher, the movie plays perfectly fine.
Here is the command:

Code:

ffmpeg -i in.mkv -map 0 -c:s copy -c:v libsvtav1 -pix_fmt yuv420p10le -svtav1-params tune=0:irefresh-type=2:enable-overlays=1:scd=1 -g 240 -movflags +faststart -preset 5  -ac 6 -c:a libopus -b:a 256k -crf 30 out.mkv

I tried both jellyfin-ffmpeg and the latest build from github.
Does anyone have suggestions? I would be very thankful.
