Hello, I'm wondering what the best approach would be for the playback
of 25 fps video on 4 fullscreen 1024x768 resolution vga screens,
using one of the new g5s with pci-express bus architecture. The video
(s) displayed will be different on each screen, but should run in sync.
One approach would be to render a strip of 4x1024 wide and strech a
jit.window horizontally over the four screens.
Another approach would be to render a block of 2x1024 and 2x768 and
strech one jit.window horizontally and vertically over the four screens.
Third approach would be 4 seperate clips to four seperate
jit.windows. Or a combination of the options above ;)
I will try this all out over the weekend, and report back. My main
concern is the disk speed / data rates required to make it work.
I'm never quite sure how to calculate datarate <> bus speed <> drive
I'll be using the standard 7200 sata hd that comes with the g5. I
will start by preparing 3 different formats of photo-jpeg quicktimes :
- 4 seperate 1024x768 quicktimes
- 1 4096x768 quicktime clip
- 1 2048x1536 quicktime clip
Will the drivespeed be sufficient for 25fps playback of these clips ?
