I'd like to see a video showing the experiment with some of the more complex interferometer setups so that it's easier to understand the coherent effect.

I've seen series like this before:

But they never seem to explain cases where the expected outputs are all destructive.

I can dig down the reddit hole with lots of interesting ideas and explanations:

But what I really want to see is a good experiment on video that show the effect.

Yes, I linked that video because I'd like something like that, but attempting to make all paths cancel completely and showing why it can't be done.
