Funny

Sounds romantically intended with some really fucked up and distorted ideas mixed in. I'll take as given that she doesn't actually hold any of the racism she expressed as sincere beliefs. Part of you twigged that though she seemed to be trying to be nice in a really weird way, something seemed off and it is a bit off. If you imagine she mailed you a knife and a key to her house and said now you have the power to attack me and I'm vulnerable you'd probably see much more clearly and obviously how unromantic and off-putting and psychotic that is despite following a very similar logic.

In both these scenarios she's putting her life in your hands to demonstrate trust, but there's an implicit suggestion there that you would or could ever do something like that and only don't because of your undying devotion. There's a kind of twisted view of humanity there that that ruining someone's life on purpose with kompromat is something people generally do to one another but for the power love to zovercome it. It's sort of a red flag that she might think that way but really you know her better than any of us and also whether you think she's good for you. That she decided this would be a good idea and a nice birthday gift is disturbing enough that it's probably worth bringing up though. I think if it was me I'd probably express appreciation for the sentiment but also delete the video and tell them I had done so. Unfortunately you could never prove that you have deleted it so her messed up little game will always work in the manner that she intended but the extent to which this is something to worry about long term is something you can evaluate from her reaction to this news and your explanation of why it didn't feel right. Sometimes people do dumb shit, especially when they think they've spotted an opportunity for comedy and can't see their actions in a different light until after they've done the stupid thing. There's a chance here for this stupid thing to be a memory between just the two of you that neither of you has to worry about again so long as you point out that it wasn't as romantic as she thought it was and also delete whatever email or communication was used to send the video plus the video itself. If she's able to feel a bit embarrassed and move on you're probably fine, if she digs in and gets offended and tries to play similar fucked up games, then you might want to consider getting out before things escalate.
