I paid for personal storage on @nostr.build so I can upload videos myself.

nostr.build media uploader

Image, video and media uploader for Nostr, Damus, Primal, YakiHonne, noStrudel, snort.social, Iris.to, astral.ninja, and most all nostr clients. Up...

is good site for uploading videos and you can buy more space for your uploads if you need that sort of thing

Direct upload can be easily done from clients like #Damus or #Amethyst and generally they use nostr.build as source to upload the video and give you a link to put on the note.

Definitely checkout Nostr.build. That’s what you’re looking for to post videos directly!
