Didn't you just ask this yesterday HERE? The answer is still no, not without re-encoding you videos.

You should be able to bring the Quicktime file into Final Cut (and probably other programs as well), add the watermark as an overlay, and then output the composite to a new Quicktime file. Just be aware that if you're bringing in a degraded Quicktime file (meaning a compressed one for Web use, rather than a full-resolution one,) you will probably have a little bit of further degradation by rendering it out again.

If you have it, your best bet would be to use the original project file from which the edited video was output, and just add the watermark as an overlay to the edited project and output that as a new Quicktime file.

There actually are several ways to add a watermark to video within Quicktime Pro without re-encoding anything. What I describe below is not the only way to do it, but it is the simplest way of doing it with a minimum of effort involved. Quicktime Pro and any graphics editing program such as Photoshop or even MS Paint are all the software that you'll need.

First, create a blank document that is the same size as the video you intend to watermark. In that document type whatever text you would like to use as your watermark so that you end up with black text on a white background. Keep in mind that the text on the video will be the same size and in the same position as whatever you type here. Save that file as a .png file.

Now, open the video in question using Quicktime Pro and access the Video Properties window. (I'm on a Mac, so that's Command-J. For PC, I'm not sure how to get to it, sorry.) The upper portion of the Video Properties window should list each of the various tracks that make up the Quicktime file. Click on the Video Track to select it and then click on the Visual Settings button/tab below the track list. On the lower left of the window you should see a smaller window labeled "Mask". Below that smaller window, click the Choose button and select the file you had previously created. Now, click the Invert button so that you end up with white text on a black background. Next, select Straight Alpha Blend from the Transparency pull-down menu and turn the Transparency Level all the way down to 0%. You should now have pale gray text superimposed over the video. Save the QT file and you are done.

There are better ways to go about it, but like I said before, this is the simplest approach with the least amount of effort that doesn't require editing or compositing software and that allows you to avoid having to re-encode the video. Based on the question it seemed like simple and quick was what you were looking for. I would be happy to answer any questions you might have, so feel free to ask.
