Hello there,

I'm working on a theatre project which needs a 18,5 meter panoramic projection. There are quite a few approaches to tackling this challenge. Indeed, most of them highly speculative ...

The plan at the moment is to have 4 projectors, driven by two new 2,66 Intel macs and catalyst v4. Each mac 2 GB (4x512mb) ram and an ati x1900 grphx card.

The resolution on the media files should preferably be 1024x768, but could also be 768x576. Codec would be photo-jpeg at 60 or 70 %.

Setup for each output would be pretty standard, 2 layers of video and possibly a masking (grphcs) layer. Hoping to use the new seamless panorama features in v.4.

• First question : Would a 10k sata disk be fast enough to drive those ± 4 layers of video + 2 masking layers for each machine ?

• Second question : Would it be possible to do the 4 outputs from one computer with the ati card and two dualhead2go's ? It would mean ± 8 layers of 768x576 photojpeg 60% video to four outputs via one machine.

• Third question : In case the dualhead2go solution has a chance of working, would it be possible to use one large (3072x576) quicktime for the four outputs ?

• Last question : Not having to render masks into the quicktime(s) would save us _a lot_ of time. This would mean moving one or multiple masks over the four screens in real-time. Would this be possible in the dualhead2go option ?

That's it for now, am sure there are more issues to it though

Thanks !
