Do you know of any museums which watermark their online images?

COBRA! — Wed, 29 Apr 2009 12:58:19 -0800

I need a list of museums which watermark (or otherwise alter for the purpose of control) the images they make available online. Actually, I'm arguing that it's rarely done, and I don't find a lot of examples. But I worry about being wrong and missing a bunch.

video watermarking?

Whenever I watch .mov files now (like these: 1, 2, 3), I get small, vertical colored bars that randomly pop into the video, then fade after a few seconds. I also get this on old .mov files on my computer that didn't have it before I installed the newest version of quicktime. What's up with that?

Tracking Images across the webz

I am interested in using Digimarc watermarks to track images across the web. Does anyone have an opinion on their MarcSpider tracking engine? Are there alternative techniques/technology? For those who don't know. Digimarc sells digital watermarks for images. Most people purchase these to protect their copyright. At the highest subsription level (and through their ImageBridge commercial solution), Digimarc tracks the occurence of your images via a search engine/spider. This could be another tool to track where on the web my clients work is being discussed. Google will catch the text, sure.. but this is more targeted. Because watermarks require a reading process to detect the embedded data (=cpu time), and other factors, I have a feeling their search scope is severely limited.
Does anyone else offer a similar service?

OS X tools for overlaying a copyright notice over a film

mrbill — Wed, 24 Nov 2004 10:07:34 -0800

I'm involved with a "currently in post-production" motion picture. I've got a MPEG of the film (although I can convert to any needed format), and need to overlay a text copyright notice over the entire film so that its visible at the top or bottom of the screen. Can anyone suggest tools for doing this under OS X? Free/shareware/donationware tools would be preferred, as we don't have the budget for Apple's pro-level video software. I've been doing a lot of work with iMovie and ffmpegX. :)
