Decomb filter is set and will increase the effort needed. Unless the video is noticeably interlaced (line artifacts, not likely for most blurays) and you’re trying to fix that there’s no reason to run it. (Note however this is the least time intensive thing you’re doing, I just mention it for completeness, to be honest handbrake may have detection so it only runs while needed but I’ve always set it manually and only as needed)
Besides that though you’re using software encoding which while better will take much longer. Try setting the encoding tune under video settings to something faster.
Alternatively set your encoder to use NVENC version of the scheme you want (264) With NVENC encoding 30 minutes without anything else should take 7 minutes or so.
One last thing. You seem to have it set to burn subtitles in. This generates a lot of extra work and is not advisable unless your hardware or software does not support soft-subs as a separate stream in for instance an mkv file. Most modern streaming devices will handle plain text and PGS image subtitles in my experience. Try instead to set the default and forced flags if you want subtitles to be on by default.
The instance you’re on censors slurs. Mainly the b-word (misogynist term for women), but also the n-word (racial slur), various other lesser used racial slurs.
It does not censor general profanity like fuck, ass, shit.
Your only option is to open an account on another instance that doesn’t have as strict of a filter. Lemmy world for instance.
All content even from other instances is subject to this filter because it goes through your instance to get to you via federation.
