You should have used the propper event-kind to begin with. You posted your videos on what is effectively nostr's version of a post-it note; instead of what would be analogous to a film roll or however you want to put it.

This means it will always be messy, no structure, nothing, and it will by burried under all the other post it notes you will end up posting. And any dedicated video app would know to find your stuff (because it looks for filmrolls, not post-it notes)

Also if you are taking this serious (by the looks of it you are), did you take any consideration as to what blossom server you are using?
