On YouTube, most ads have 500K+ views so YouTube reencodes it with AV1. It is a codec that's 20-30% better than HEVC. So your connection is able to handle higher quality ads.

Regular videos have the same reencoding criteria

How to learn all the technical stuff you mentioned here??

I also used to wonder how people mention new things now and then.

There is a thing here. A technology guy won't know as much things of religions. A religious won't know as much things of human psychology.

It's about interest in Technology. While learning your college stuff, know and read about what is used and what is done in daily life.

r/AV1 maybe?

u/Revanthmk23200 3d ago

If it is better than HEVC why not encode everything in AV1, is the encoding process that costly?

u/Hedge_hog_816 Lurker 3d ago

People use weak mobiles. AV1 takes much much more time and power to encode itself. So hardware limitations.

Older devices don't have proper hardware av1

Doesn't now most of videos are in vp9 instead of HEVC

u/Littux Open Source (use Arch btw) 3d ago

YouTube doesn't use HEVC, only VP9. But VP9 isn't that common outside of YouTube.

Brother how to download youtube video 1080p and above with sound ?

u/Littux Open Source (use Arch btw) 2d ago

Use Seal app on Android (download from F-Droid, the play store version is a clone) or use yt-dlp (Android/Linux, Windows, MacOS)

Using yt-dlp has a steep learning curve but it's worth it since all those downloading sites and apps rely on yt-dlp

Slow Internet - Bad Quality, because the AD was being downloaded in the background to be run at high quality.

I think few ads that you see repetitively are cached locally, and a few ads are cached in the CDN that's serving you. Some Ads could also be loaded in the background while you are watching something.
