Peertube has been a fantastic way to mirror videos from Youtube and have embedded versions that are ad- and cookie-free. It's got support for mirroring channels from the other video providers which makes it a breeze to run. I've deployed it for various communities:

- https://watch.ocaml.org (for all the OCaml language talks over the past 20 years)

- https://watch.eeg.cl.cam.ac.uk (for our research group on environmental science)

- https://crank.recoil.org (for my personal talks and videos)

The fediverse integration is a minor plus, but the permanent nature of the video hosting. My only wish is that there was a way to bidirectionally mirror view counts, so that the Peertube mirrors don't look like a ghost town.
