Is watermarking on movie Blu-rays a thing? (lemmy.world)

Is that (still) a thing? How safe is it to rip Blu-rays for seeding?

Edit: clarification. I mean the invisible kind of watermark used as a unique identifier of the disc and associated file.

I've never seen any watermarks on my BR rips.

You don't that's the thing. I should have clarified my post.

You can add invisible watermarks to a bitstream to track the file back to the disc. Basically like an unique identifier. If you were to share that ripped Blu-ray illegally, the law enforcement could proof that you (as the buyer of the disc) ripped it.

Maybe for screeners where the volume is low. Commercial Blu-ray, it’s a lost cause with millions of discs.
