> A secure watermark embedded into every frame of the video which cannot be seen and cannot be removed.
Welcome to 1999. Apply a slight blur to the frame and ba-dah-boom, watermark gone. Or, train a neural network to identify this watermark and replace it with colour/intensity from nearby pixels. Maybe even opencv can process each frame.
So... sign up to a website using two different usernames. Download the same video, do a diff on these two videos and find what they are then reverse engineer the differences. It may even be possible to compare two frames of just one video and look for differences with a diff.
Level 1 would be applying this watermark in the same 'hidden' place on the frame, e.g. 10px from left, 10px from top whatever, level 2 would be randomising the position, level 3 would be admitting to client who asked for this that it isn't viable.
Very Best case scenario: you find your pirate. Yeah. Do you sue? They won't have any money, blood from a stone etc, so you probably just remove their account instead. So they sign up with a different IP and different payment details and round you go.
As each download for each user will have to be watermarked dynamically, you're going to need big servers and explain to your users why they can't download the video immediately. That's gonna piss off more genuine users who want the wank immediately imo.
There are almost an infinite amount of ways to bypass such "DNA" finger-printing security, but that's assuming your content isn't already available for free elsewhere.
"Obscene or indecent" coming from xvid is risible.

Oh, what if one of your user's account's is hacked?...Running a brute force password attack on your sites then using the video downloads would be trivial.
