Watermark a DVD

Post by NFAtoys »

HELP! Unless I'm totally mistaken, DLP supported a technique that could create a DVD with a watermark in the video letting you quickly create TEST or DEMO DVDs that could be handed out for evaluation, without giving away a useful DVD that could be resold. And with a simple setting change, remove the watermark.

I've searched all over the help file for information on this, but I can't find it anywhere. So DLP must not be using the term Watermark for this feature. Any help is greatly appreciated. Thanks.

I'm not sure. As I understand it, a watermark doesn't prevent copying, and you really can't stop someone from selling or giving away the DVD once it's in their possession. It's just a hidden identification. So, if you watermark each (burned) copy with a different serial number you'd know who leaked the copy or transferred the original.

I think you could watermark the MPEG file before authoring/burning the DVD, but I'm not up to speed on what watermarking software is available..

I assume re-encoding the MPEG (i.e. DVDshrink) would remove the watermark.

With DLP, you can turn-on "flags" for CSS (digital copy protection) and Macrovision (analog copy protection). But, the actual copy protection has to be done by someone with the license and software (the replication/duplication house). And of course, these copy protections are easily bypassed.

No, I wasn't talking about copy protection. I'm sure I read somewhere in the DLP help, or tips, or the old forum board, that you could easily watermark a video without specifically recoding the asset This would leave a visible indicator in the on-screen image that the DVD was a demo. Yes, the DVD could be easily copied, but each copy would contain the visible watermark.

It's been quit a while since I remember reading this somewhere, maybe 3 or 4 years ago, but I'm sure it was in something related to DLP.

I seem to recall something about watermarks too.
I'll dig deeply into my archives & see what I can find here....it would be VERY useful for test discs

The only thing I can think of to use as a watermark is to add a BOV to the video.
