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.

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

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.

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