Super Large Format Playback

[goblynn93]

I have to project a waterfall image onto a surface that will have a pixel space of 2816x704 ... I’ve created a render of a video 2536x724 to give me 20 pixels of space to play with. I’ve used Quicktime h.264 to render with from After Effects.

Problem I have is nothing will play this file smooth. Well nothing that can feed me as much resolution as I need... Our planned playback device is a PC with Matrox 3 head vga card... File won’t even start to play on that machine.

File plays just fine on my laptop with an external monitor, half video on my laptopscreen and half on my external monitor. Looks great, runs almost full frame rate.

Quicktime reports this video as:
Source: ...
Format: H.264, 2836x724, Millions
Movie FPS: 29.97
Playback FPS: 24.x(average when on laptop)
Data Size: 190.88mb
Data Rate: 18.81 mbits/s
Current Time: ...
Duration: 00.01:25.01
Normal Size: 2836x724 pixels
Current Size: 2836x724 pixels

What do I need to do to make this thing playable without loosing much more reslolution? (the clip is created from a SD clip that’s been tiled left and right and then made to fit top to bottom... shooting onto a scrim surface so a little res loss is ok... much more then what I have already is bad)

Thanks for anything anyone can suggest!

Next thing would be to try one of the NVIDIA machines with TwinHead technology.

Worse case scenario: two machines with aligned projectors.
