I have a feeling you just don't understand how a binary search functions even with AI you wouldn't be using a binary search at that point

If you have camera footage from 4pm to 8pm with event lasting 1 minute but no changes occur to the background/foreground how exactly are you using recursion to determine which part of the footage even occurred without going through the entire film. Are you picking at random?

The way you're describing AI is not binary search and so it can't be used in this example. Also most public cameras are not 8K cameras they don't contain a lot of detail, so the argument that they could catch something subtle kinda gets blown out of the water. You can't just use AI as a cop out for not understanding how function behaves or works
