Want to add movies to the archive? Create an npub that you will use to post them, so as to not spam your regular follows.
I usually upload to either archive.org or nostr.build. Archive is more likely to be taken down, but it's free. Nostr.build costs money, but your movies will not be taken down.
Make sure your movies are in an MP4 container, with h264 video and AAC audio for best compatability. Keeping the size under 2gb will be optimal. Other formats will not work well on iOS.
Then you simply make a note with the title, a link to a cover image, the link to the movie you've uploaded, and genre hashtags. Add the #kinostr hashtag for maximum visibility.
Let me know if you want to join in, or have any questions.
