Step 1: setup an automated setup for playing video and detecting if the output was detected via the watermarking system.
Step 2: Run the whole thing through an optimizer seeking to minimize error while not being detected.
Step 3: Wait a few hours.

Obviously I can come up with anything and you would be able to present a strategy how to beat it. But that's not the point.

Even after analyzing spectrogram and generally watching the media multiple times, trying to find anything weird.
Well, obviously when you grab infinite number of watermarked copies, you might be able see where the irregularities are. But that's not how leaks happen.
