There are many reasons for video-recording.
Probably at least $50k, I'd have to think about it more.
(It would take a fair bit of work to gather the money, but it'd probably be worth it is what I'm saying.)
Would be very valuable to rewatch formative situations, show different parts to advisors and people I trust to give me good advice, and build a better self-model. Generally watching myself from the outside and building a better model of me in the third person seems valuable, I rarely get to use the intuitions I apply to everyone else on myself, especially in naturalistic situations where I don't realise I'm being recorded.
Edit: Oh, this is for cryonics? No, I probably wouldn't pay for that, but that's correlated with me not having signed up for cryonics.
Zero. Or am I misunderstanding the question? Unless I had a major mystery about my life, what would I learn from a video of some past year of it?
