The Steam trailer video player was old and not especially great, but now perhaps it might actually work a lot better with a big upgrade.
It brings an upgraded interface with a UI that adapts to different devices, preview images when seeking through a video, faster seeking / scrubbing and transitioning to full screen, smarter bandwith use and improved handling of different aspect ratios. You can see Valve's example video below of it in action for PEAK:
As part of the upgrade, Valve said they had to go back through and re-encode every trailer that could be shown, which they said ended up "being around 400,000 video files". Whew, that's a lot huh? Some videos might be quite a low resolution though, due to being uploaded years ago where Valve don't have the original.
Valve suggest developers that uploaded trailer prior to Summer 2020 may want to re-upload, so it can be sorted into the correct format and give Steam users a better quality version.
At the same time Valve are reminding developers that they may want to hide old trailers, and ensure they actually show gameplay — get to the gameplay as quickly as possible.

For the codec, I inspected it, and it looks like they're using vp9, which is good. It's open and royalty free unlike h265 hevc. I wish they would be using av1 instead of vp9, but hey, at least it's something.
I am very surprised they are using akamai/fastly for their cdn. I would think a company like valve which must do INSANE amounts of bandwidth per year would just roll their own. Could probably save a ton of money that way, but maybe they just don't want the overhead.

I don't know anything about the topic, but I'm sure they get very special discounts?
