Video Wall Hardware/Diagnostics

Ian C's icon

There's a video wall in the lobby of our studio's office and playback stutters, stops and looks lame.

Specs:

8x 1900x1200 VGA computer monitors in 4x2 Grid

Powered by... AMD x4 3.4Ghz, 8GB RAM, 4x Nvidia GeForce 9500 GT video cards

I created a max patch (with the help of forums responses) that loads random videos from a folder and plays them full screen. A folder of 20 videos (20mb file size generally) where the patch picks a random video and plays it full screen on one of the monitors... 8 different videos, picked randomly, playing at once, across the array of monitors.

Given my hardware setup, is there a way that I can get the videos to play smoothly from Max?

A couple quick thoughts :

What are the dimensions of your videos? If they aren;t 640 480, you should make the qt.movie attributes match.

Look into OpenGL playback, like using a videoplane (see vade's oft-referred to post here : http://abstrakt.vade.info/?p=147 )

Swap out the metro with qmetro.

Is there anything else running on the computer?
