It really depends on the settings you are using for x264. If you wanna use less RAM, you can try to lower the lookahead and limit the ref.
Anyway, x264 does use a lot of RAM for such an high resolution, especially on some presets. |

I believe that x265 is more optimized for this kind of resolution, while x264 was fine-tuned for HD and later FULL HD.
Some of the useful tools available in x265 have been backported to x264, but still it's not as efficient as x265 for very high resolutions. |

Depending on what type of fiters you're using (Temporal denoising/QTGMC, etc), I have vspipe processes that exceed 11G memory. And that's just for 1080p material. I have only 32G, so I don't ever dare and try this on 4K stuff. But it stands to reason the vspipe process will go way over 40G in that case.

By the way, my first 8086 based computer (i.e. PC) had 1 MiB of RAM.

Yeah, I had one of those too with a staggering 2K and, as appropriate for real men, only HEX input "keyboard".
As for 8086/8088 I think the minimum was 512K (to be verified).

Apparently, Micro Professor (originally by what was to become Acer) is currently still manufactured(later version):- https://en.wikipedia.org/wiki/Micro-Professor_MPF-I [Above looks different to how I remember it] Hewlett Packard LabPack, was similar but much larger in a Samsonite brief case (with additional 8 bank toggle switches as well as hex keypad). EDIT: "8 bank toggle switches", why use hex, real real men use binary. IBM Personal Computer 5150, 8088, 16KB RAM (Max 640KB), PC-DOS 1.0:- http://oldcomputers.net/ibm5150.html EDIT: HP LabPack, actually looks like this one "HP 5036A MicroProcessor Lab" [although the one I remember had big toggle switches, not small DIP switches, and a lot more chips]:- http://www.hpmuseum.org/cgi-sys/cgiw...cgi?read=93495 EDIT: Took about an hour to key in a program to light up LED's in sequence and play a whooshing sound, like a rocket, time well spent, maybe.
