I use bob video filter to deinterlace the video. On Jellyfin there is horrible stutter if I don't set the framerate. Since it is sometimes sending half a field as a frame anyway, I go ahead and double it for everything.

Note that passing –bwdif and –bwdif=bob will use different “modes”. HandBrake documentation doesn't explain what the difference is, but setting bob directly has worked on all my content, so I use it by default.

HandBrakeCLI -i /dev/sr0 --bwdif=bob -cfr -r 59.94 -o dvd_track.mkv

When using ffmpeg to rip and deinterlace DVDs, I prefer the bwdif filter. It's fast, and includes what yadif does. I've never had any problems with it.

Version 7.1 supports accessing DVDs directly using dvdvideo protocol.

ffmpeg -f 'dvdvideo' -i '/dev/sr0' -vf 'bwdif' 'dvd_track.mkv'
