Wait, are you saying this logs footage automatically?
Like it'll look through footage and tag it without supervision?
In the video world we generally call it logging instead of adding tags. If it's doing that and you're targeting video editors replace the word indexing on your site with logging.
If this is the case you need to reach out to video post production houses. They should be all over this.
Your software sounds super awesome and I don't think you realize what you have on your hands from a video editors perspective.
Granted I don't have tons of footage to look through for most projects but it'd probably save me a little time.
I'd imagine if you pitched this software to stock footage companies they'd be all over it. Instead of tagging/logging the footage you could eventually have ai do it.
I think there's a service out there now where you can upload footage someone will tag/log it for a fee then upload it to multiple stock sites.
Istock shutterstock pondfive getty are some big ones. They may be interested in this tech.
I'd also consider reaching out to adobe, blackmagic and avid to see if they would want to buy this from you....or try to partner up with this other new ai company that figures out what broll that you shot is usable. ..combining your software with theirs would be huge (I'll edited the name here once I find it again)
