You should plan on making the money in shooting and editing your video.
Watermark the video, photographs all have a studio logo.

Do you notice the network logo while watching TV? Most only see it when
changing channels.

I don't know about the watermark. Are you clients going to be happy spending $$$ and then have to see your mark on every frame? I think the networks do it partly to get back five seconds each half-hour by not having to do a separate station ID check (required by the FCC).

Copy protection doesn't work. It can be defeated instantly with DVD Decrypter and many other tools, all of which are free and take one minute to download. Adding copy protection costs a lot of money in licensing fees to Macrovision, a cost you must pass on to your clients, making you less competitive.

I ran a software company back in the 1980s when many companies copy-protected their floppy disks. We didn't. What we DID do -- and what I suggest you do -- is add value in other ways that will be difficult to duplicate. These include:

1. Use top-quality packaging. This includes the case (no cheap slim-jewel boxes). It also includes the box the case comes in. If you are doing weddings. create a holding box that perhaps contains stills or other elements from the wedding. Create cover art for the packaging. Packaging increases value. Make it clear that all copies will have this same treatment.

2. Create good looking labels for the DVDs and use an inkjet (or better) printer to apply them. No paper labels and no Sharpies. Again, make it clear in your cover letter that all copies will be of this same quality. Do you think the bride really wants to give her mother a copy of the video with a Sharpie handwritten label, when only a few dollars ($20-30) would give her a professional package?

3. Emphasize the quality of the material you use for duplication. (You DO use top-quality blanks, right?). I'll admit that this is a little FUD, but a surprising number of people who do their own copies use inferior blanks, and then have problems. Find the best blanks possible, and look for a manufacturer (like Maxell) that makes longevity claims in their literature. It took me a very long time and a LOT of research, but I was able to find industrial grade CDs (not DVDs unfortunately) made by Mitsui that have been rigorously tested for longevity using accelerated aging. They cost $1.50 each, instead of $0.10 for most blanks. I can make the claim to clients that if properly stored, this CD should last for almost 200 years.

4. Emphasize convenience. Offer to drop-ship to everyone on a list (you can charge a little extra). Offer to put a personalized note in each package (like Shutterfly does for photo prints that are drop shipped).

5. Finally, put a very positive, very polite, but very firm disclaimer in your cover letter that reminds them that this is copyrighted material. This should be integrated with the marketing piece that explains all the benefits outlined above. You can also extend the FUD by saying that the best copies are made from the original source material, using industrial grade duplication equipment, and this reduces errors and increases compatibility and reliability, etc., etc., …

Great feedback.

I didn't know the replication house I use offered this feature until this forum. You see I have other events that I capture for example a Belly dance performance I capture with three cams. looks great. the client would like to impede duplication of this event.

thanks this forum i now know my replication company does it.

Are you talking about duplicating or replicating? You mention 'replication' house, but later state your client wants to duplicate the project. They are completely separate processes. Duplication means your project is copied over to multiple recordable discs. There are a lot of places that do this, and it is no different from the burners one uses at home, just that it's automated (and there typically are a number of burners). For that reason, copy protection can't be applied to a 'duplicated' disc.

If you mean replication, then the house you bring it too has sophisticated equipment to make a glass master of your dvd recordable (or DLT) and then press the image into the disc copies. You can add CSS or Macrovision to these types of discs, but it requires you to have an authoring app that will add the copy protection to your project before bringing it to be replicated. Since you can't use a recordable disc in this fashion, it can't be used as the reference disc for glass mastering--you need a DLT.
