High-resolution movie of Einstein@Home screen saver?

(moderation:
We have a large video screen in our lobby at the Perimeter Institute, and I would like to show a movie of the Einstein@Home screen saver there. This would require a high resolution so that it looks good (twice HD). The movies I found on Youtube are not good enough.
- Does such a movie already exist?
- Is there an Einstein@Home press office I could contact?
- Is there an alternative, similar movie that I could show instead?
Thanks,

I think I may be able to oblige you there. :-)
To be certain twice HD = 2048 x ? Plus how long would you like this movie to run for ?

Thanks!
The resolution we are looking for is 1920 x 1080. I also hear that the whole movie should be less than 300 MByte. We usually cycle through several items on the video wall, so anything between 30 seconds and 2 minutes should be fine. We can also show a few lines of explanatory text next to it (on a different section of the screen) -- if you have some suggestions there I'd appreciate them.

OK. That's do-able without much fuss. There are several solutions. Personally I'd mildly attack the source code and rebuild. FWIW here is a good/simple method :
- one can start the screensaver at a given resolution and force full screen display.
- a suitable card/monitor will grant said choice to the OpenGL instance.
- there are many free & good ( OpenGL ) realtime-screen-capture-to-codec programs/utilities out there. The main issue/feature for these is how easily they hook to process. I vaguely remember doing this before, a few years ago, so I'll check what's about.
Which codec/format would you prefer ?
Cheers, Mike.

The video will be displayed

The video will be displayed by a Mac Mini via Safari, so any codec that is supported by the configuration will work. I don't know what codecs and formats exactly are supported -- I can find out if necessary.
