Oh that's a great tip, I set it to "indistinguishable" and it 3x-ed the (almost) same gameplay clip, but it does look the best so far. But if what you are saying is true, with the encoding the previous encoder's artifacts, doesn't that mean I should record in lossless?

I did try a video of my desktop doing almost nothing, and AV1 rf23 compressed it 17x. That's nice. I'll now try re-coding this "indistinguishable" h264 preset video and to record a lossless one and to re-code that as well.

I've gotten that far, but no farther

I was and am searching there I just can't find it in the dropdown. I might be blind, but I checked multiple times.

Haha, yeah. I plan on editing them down as well when I'll have the time.

it became 504 MiB, the original was 306.

while it was doing that I tried compressing a 50Mbps clip. And I think you're gut feeling will be right, I managed to compress it with AV1 rf47 it got reduced to a 4th of it's size and it looks almost the same as the 15Mbps one. However, sadly I saw how good the raw 50Mbps one looks, so I don't think I'll go that low. Finding the sweet spot will take forever! Also isn't 50Mbps too high, the video looks amazing, but isn't that abnormally high?

"15k hard" is the control h264 file rest doesn't matter I think

but in the meantime I did some encoding to h265, and I managed to get a smaller file size however the quality sucked, so I lowered the crf and it's larger again.

my AMD 6000 series GPU only supports decoding for AV1. And yeah I quietly decided that 60fps will be perfect.

I can't find it and a quick google told me that neither do others

I am doing that since I made that post, making educated guesses at AV1 configs. Every single one of my AV1 encoded files turned out larger than the original. I recorded the original with 15mbps, and that seems enough (as I did the cheating my self a teaser of lategame thing).

I set the OBS's recording to 60fps, hopefully that way I dodge the weird half frames, that you are talking about.

I set the quality RF to 30 in HandBreak, and as you can see it almost doubled the filesize. how?

I tried encoding to AV1 with OBS and it stopped working. I tried converting h264 to AV1 and the filesize became larger. I think I'll stick to h264 lol

I did a test recording of 2 minutes (1440p 60fps 15000kbps) it's 320MBs, encoded it with AV1 and the file became 392MBs, it also lost all but the first audio track.

Anyways, I estimate a 6.8TB for 1k hours. Seems doable.

well I checked. My GPU does support AV1, but only decode, and OBS doesn't support h265. So is my only (good) option is to use a SVT-AV1? How slow it that really?
