X264 Image Quality Analysis: SLOW is NOT worth it (GN Follow-Up)

Apex Legends

Award

Title

Description

I sat out to finally prove something that I've been saying for a long time: X264 Slow is not as magical as people say it is, and it's definitely not worth the performance trade-off for 99% of streamers. Oh, and AMD's streaming benchmark at E3 2019 was a really terrible showing. I think I did a good job here and after many more hours than I'd prefer to admit, I'm ready to show you why.
CLARIFICATION: The Elgato CAM LINK and CAM LINK 4K support 4:2:2 YUY2. I forgot about those when I was scripting. I don't see those as gaming devices. The HD60S/Pro's YUY2 modes are probably usable, but I've been unable to confirm actual 4:2:2 color space. The point was, don't use their XRGB modes. Use YUY2 or NV12 from Elgato.

This is a follow-up to GamersNexus's video: Explaining AMD's Misleading Marketing: X264 Stream Quality & Benchmarks -- https://www.youtube.com/watch?v=jzaXvEPyKd0

What I hope to clear up here is that the problem is not "Slow is too intense so no one uses it, thus it's a bad benchmark" but rather that "Slow literally should not be used for this purpose."

Also working against AMD is they oddly chose 10mbps for their bitrate - at which point, my testing proves that even VeryFast is of similar quality to Slow, so using slow was still a very poor benchmark choice.

There's a lot that went into this particular project that was too much to cram into this video (crazy to think, given its length) so I have ALL the nerdy details in my write-up here: https://eposvox.com/2019/06/x264-iq-analysis-slow/
