  • Frankly, for anything other than real-time encoding, I don’t actually consider encoding time to be a huge deal. None of my encodes were slower than 3fps on my 5800x3d, which is plenty for running on my media server as overnight job. For real-time encoding, I would just grab a Intel Arc card, and redo the whole thing since the bitrates will be different anyways.

    Encoding speed heavily depends on your preset. Veryslow will give you better compression than medium or fast, but at a heavy expense of encoding speed. You’re not gonna re-encode a movie overnight on slow preset. GPU encoding will also give you worse result than CPU encode so that’s something one would have to take into consideration. It’s not a big deal when you’re streaming, but if it’s for video files, I’d much prefer using the CPU.

    I consider the ‘good enough’ level to be, if I didn’t pixel peep, I couldn’t tell the difference. The visually lossless levels were the first crf levels where I couldn’t tell a quality difference even when pixel peeping with imgsli. I also included VAMF results, which say that the quality loss levels are all the same at a pixel level.

    I was mostly talking about how you organised your table by using CRF values as the rows. It implies that one should compare the results in each row, however that wouldn’t be a comparison that makes much sense. E.g. looking at row “24” one might think that av1 is less effective than h264/5 due to greater file size, but the video quality is vastly different. A more “informative” way to present the data might have been to organise each row by their vmaf score.

    Hopefully I don’t come across as too cross or argumentative, just want to give some feedback on how to present the data in clearer way for people who aren’t familiar with how encoding works.








  • How often do you interact with tankies…?

    Outside of dealing with the odd report on our instance, I don’t. I’m not sure what people get out of seeking communities they dislike/don’t care for.

    I’ve muted hexbear and blocked some political leaning “world news” communities, programming.dev also hides political communities unless you specifically subscribe to them so that doesn’t show up for our users in all either.

    Granted, I don’t see every report made on our instance, but from all the reports I’ve seen since Hamas’ terror attack, the worst one was someone wanting Israelis to leave the land and for the colonisers that are actively taking more land to repay the people they took the homes from with forced labour. Other than that one, even simple things like “Free Palestine” has been reported as hate speech. So you really can’t tell what a single person mean when they talk about hate speech or “supporting Hamas” without them elaborating on where they draw the line.

    Of course there are places where people will defend Hamas’ terror attacks. You can also find people who claims Ukraine is ruled by nazis, that 9/11 was justified, covid is a hoax, Holocaust never happened, etc… The question is if you see those opinions popping up on “normal” communities and supported by upvotes.
