Question / Help Looking for Quality/Size Spreadsheet

I was searching threads looking for good 1080p/60fps recording settings and found a thread that someone had compiled a spreadsheet comparing all the Encoders/Settings/File Sizes etc and now I cant find it.

It was very handy because I am trying to find a good compromise between quality and size. I have been playing around with my settings all week and I have some 20 minute videos around 3 or 4 gb and some 30 minute videos around 30gb. The 30gb does look better but I don't think it looks 7-10x better, plus its quicker to encode + upload smaller files obviously.

The other reason (and sort of a side question) is that I would like to record at 1440p since thats what I play at and it looks much better, but then an 11 minute video comes out to 27gb (much much too big). Would be nice to min/max my settings for a good balance.

To find out what YouTube recommends, go here: https://support.google.com/youtube/answer/1722171 and expand "Bitrate".

When I made this video, I recorded over 1000 hours of 1080p60 video at 20Mb/s using NVEnc. IMO the source video was alright but it definitely looked better at 30Mb/s, but because I knew I was going to need to record an insane amount of video, I compromised on quality a bit. You really should judge for yourself instead of following someone's chart. Find out what looks "good enough" experimentally by recording sample video at various bitrates and then watching it.

Also, 2560x1440 resolution video has 16/9 more pixels per frame than 1920x1080 resolution video. You can expect it to require 1.777 (repeating of course) more bitrate to look the same quality.

@Boildown The recommendations are trash though :/

Its the same like the assumption 60fps needs twice the bitrate compared to 30. Which is completely wrong.

You cant take it so simple here either.

I agree that 60fps doesn't need twice the bitrate as 30fps. The video complexity is spread out over twice the frames, so the even though you have twice as many frames to encode with the same amount of bits, the codec will be extra effective at compressing them.

Meh, this is splitting far more hairs than 60fps vs 30fps. There's something to what you say, due to better macroblocking and probably other stuff, but this isn't like 1080p vs 480p. Especially with H.264, going from 1080p to 1440p isn't going to net some great extra efficiencies. 1.778 times the bitrate will be a harmless slight overestimation of how much is required for precisely the same quality.

About the YouTube recommendations, keeping in mind the OP's stipulations of a good compromise between quality and size, how would you change them? I suspect you'd increase the bitrate but I'm not sure.
