In what quality should I render after effects for uploading to YouTube?

I downloaded a project in which I put my own music, text and pictures and got a good slideshow. Of course, with animations from AE. The video lasts 1 min 10 sec. I put the best quality and 1920 x 1080 in the render. The render took 10 minutes, as a result, my video for 1.1 minutes weighs 21gb)). Yes, of course the quality is very cool) the detail is just pleasing, but even on my i7 I started to include a percentage of 100% and hung up, and once crashed because 8gb is not enough:).

How right it is necessary to save that would load the video on YouTube or Vimeo (video presentation) I will be glad if you tell me exactly what settings. adobe after effects cc 2018
