My basic idea is that most videos can start out kind 21, and go onto your pin-wall/gallery, and you can then transform some to kind 22, and then they show up in the reels.

The video only needs to exist once, so this is sort of like pinning a video to the reels feed. You can remove the video from that feed, by deleting that kind 22 event.

And the "normal" kind 1 clients just display the kind 21, when you first create it, in their chronologic feed. The kind 21 event is the one that goes into your albums and stuff.

We can have alternate paths, where you tag a kind 21 with #reels (so that we treat it as if it were kind 22), or you upload a video directly to kind 22.

Another thing is that you can do this to other people's kind 21 events. Or create a kind 21 or 22 event for someone else's video. You can pin their video to your wall or send it to the reels feed.
