afaik if you want to retain as much quality as possible while saving space you do want to do it on the CPU (so not hw accelerated - slow)

Has anyone tried this? OP, have you? Is it fast? I have a tv show that I’ve ripped from blue-ray. It is 600GB and I wanted to save some space, but whenever I try to convert, it’s awfully slow. I have a pretty beefy setup, Ryzen 7 5800xt CPU and a 9070xt GPU.

Could you please expand on that? What do you mean?

Haha yes, I use it regularly! And yes, it’ll be plenty fast on your system. I have very deliberately gone over the code base looking for inefficiencies six times now, so it runs nice and lean - I do an efficiency/hygiene pass every couple of releases to make sure bloat doesn’t creep in.
As ark3@lemmy.dbzer0.com said, CPU encoding is slow but it preserves the most quality. No kidding, it really is night and day compared to GPU encoding - for this, just tick “Precision mode” in HISTV. It’s about 1x speed on most videos, so a 45 minute file will take about 45 minutes.
GPU does go a lot faster, my 7900 XTX rips through 1080p at about 28x speed so a 45 minute file takes about 2 minutes. This is good enough for most content; set the multiplier to 2x or 3x with a bitrate of 4 if you want better GPU quality in HISTV. The multiplier says how high the peak bitrate can go, so you keep more data for fast-moving scenes, without forcing the encoder to keep useless data for slow scenes.

Thank you so much. It’s literally the TV show Friends. I bought the Blu-rays for the whole 10 seasons years ago and I remember using MakeMKV app. It’s high quality because I ripped them to the highest the app allowed I remember but they take so much space that moving them around from that slow hdd I have them on takes literal hours. So, knowing what kind of show it is, what settings do you suggest?

Ah, then the real slowness is going to come from having them on a spinning disk HDD. For friends, 4Mbps target bitrate should be plenty, with the 2x multiplier should be enough to preserve detail. No need to touch anything else, you don’t need precision mode for it. Try that on just one episode and see how you go!
