Hoping I can pick the brains of the group…

A marketing agency has approached us with a concept for a display of 4K TVs.  Stripping away the creative it's basically a video wall made up of 4K TVs.  The problem is that they want each TV to be displaying a full 4K stream, so the pixels add up very quickly.

4K is 3840 x 2160.

If this hypothetical video wall was 5 TVs across by 4 TVs down, the overall canvas would be 19,200 x 8640.  I think the actual design was for even more, I think it was 8 across (30,720 pixels).

I really don't think it's feasible to work at such a high resolution in any software package.  I've had one After Effects project that was about 10K x 1080, and probably the biggest I've done was about 7K x 3K, and I really wouldn't want to go much bigger in After Effects.  However I don't think any compositing package - or even software package - would be much fun working with projects in then 10's of thousands of pixels.

Apart from the playback issues (don't know how they plan on playing back to 20 - 30 4K TVs, perhaps Watchout can do it?) I'm not sure how to approach the project without doing it at a lower res and scaling up.  And that's what we would normally do - and often do when the delivery resolution gets too high - but the whole point of this marketing exercise is to have each TV playing back a full res 4K stream…

So I am wondering what are the largest resolutions that people here work with successfully?  If we had access to a few gigapixel photographs would it be possible to do a simple slideshow type thing at 20 or 30K?
