I recorded the latest video in WQHD resolution, so I guess I'll find out how my PeerTube installation at https://video.typica.us/ deals with that (should be fine). It handles 4K just fine. Still need to upgrade that server. It's running out of storage space and another core would be nice to speed up the transcoding jobs.
To be notified when that and future videos are available, you can follow @neal@video.typica.us from your favorite fediverse account.
