He told them that even if the CCTV log went back to the earth's formation, they would only need to take about 57 stills to pinpoint the second the bike was stolen (apparently they were not persuaded).
I can't find this post from a physicist, but they had their bicycle stolen and the police had given up searching the CCTV log because it was taking them too long, despite the fact that it was pointed at the bicycle.

2^57 seconds is about 4.5 × 10^9 years, which is the age of the universe. They would only need that many stills because it would be possible to do a binary search on the footage, as each frame either has the bike in it or does not.
'bifurcate the problem space' sounds so Silicon Valley.
A brute force (non-targetted) binary search may always be an option if you have a problem where you don't even know where to look.
