Thanks for putting this comparison together! My main takeaway is that there is almost no difference in quality between veryfast and slow CPU encoding, except that slow puts vastly more strain on the CPU. Good to know, since my Streaming PC's i7-4790 is struggling to encode 60 fps 1080p @ 6000 kbps on medium. I think I will stick with fast and be happy with it until Twitch increases their maximum allowed bitrate. Very useful vid!
dude never go for 1080p/60, even twitch partner dont use 1080p/60, best sweet spot is 720p/60 at 6000kbps, if you are partner then 1664x936p/60 at 8500 kbps, REMEMBER: 8500 kbps bitrate is only allowed for TWITCH PARTNER!
also here is the link to the video for more explanation whitch made my life easier and stream quality mutch better than ever : ua-cam.com/video/gOirjHIRNMY/v-deo.html&ab_channel=AlphaTube
I believe with 12th gen, using X264 slow is a non-issue anymore. Might be able to squeeze slightly better image reproduction off of using 12th gen x264 slow than on any other platform. Though, take this with a grain of salt.
that is the unaffected quality of the game image, as if it was not being captured. basically like the raw footage without the encoding and compression added.

Personally I can see a discernible difference. Very fast is a lot more blocky especially at lower bitrates. Medium may be the sweet spot.

@@scar2k158 you can stream up to 10k even without being partnered btw ~ its not 2016 anymore

quick tip: never use CBR (constante bitrate), but CFR (constante quality perception). see ffmpeg h264 documentation for more info about this flag.
and how many value did you use to get same bitrate?
Its actually work, streaming look amazing with x264 CFR (18) and very fast pretty good option for quality and performance, ty!
o perceptible diff... but CPU stress is very notable
In mine new tests Skylake Quicksync H264 soo close to x264 Slow with 16000 kbps in Quality.
i need help...can you please explain what is SOURCE..? thanks

Nice
what is your prosesor bro
What CPU u used for this video?
Core i9 gen 14th what can run?
fast
Joke?
