Active Silicon - frame grapper - LFG4-MM-PE1

[Claes]

I have a G5 with an Active Silicon Frame capture card (LFG4-MM-PE1) build in
I grap 3 chanals composite video and show them with the Catalyst and a Matrox Triblehead analog in realtime 2400x600p.
The problem I have, is that the signal is not running smoothly.
Then a turn off the preview on screen one, they are running more smoothly, but not good.
It looks like the G5 has much more kraft to run it, Catalyst is only use 17% proc. kraft

Can some one help me with the problem. I think it must be a setup thing in the Catalyst

Best Regards
Claes

which g5?
what refresh rates you run your screens?

---

triple heads on older g5 not recommended at all.
totally overwhelms older graphics cards. pre pci-express.

also different refresh rates with older graphics cards - and triple head- never resolved by graphics drivers.
works ok in intel macs.

Hi Richard
We have a new Mac 3G 8Core Intel MacPro with a 5GRAM and ATI X1900XT and V4 Catalyst.
The refresh rates are 60
We are working with a Matrox Triple Head2GO - Digital Edition. Sorry

I got a new driver from Active Silicon, then I will try.

the driver you mention - isnt new - same as before.

[Claes]

I really don't now the operating system, I will tjek it later today.
The system are build by Simon Pugsley, and he change it before we made the setup. Simon is on holiday right now.

I stay in Denmark, and help Kristian Dreier from Litecom A/S with a broadcast projekt "Power of 10".

I grateful for you help

if you are in denmark - then arent you running at 25/50Hz?

You need to set your screens to the same refresh rate.
Check with simon

[Claes]

I got mail from Simon. I will try to work with it tomorrow.
All the signals are running 60Hz incl. the projectors, but I think the capture card are runing 50Hz (Pal).
I will inform you tomorrow.

yes pal is 50/25FPS. it is one of the critical things when doing video input to use the right refresh rate.

what exact resolutions are your screens?
including 2nd output.

The Operating system on the G5 Mac OS X vers. 10.4.11
2x3G Quad
7GB 667 MHz DDR2 FB-DIMM
ATA, RadeonX1900
Triplehead 2GO, digital

Display 1 - Cinema: 1680x1050p
Display 2 - Display: 2400x600p @60Hz

[samsc]

Display 1 - Cinema: 1680x1050p
Display 2 - Display: 2400x600p @60Hz

what frequency for the cinema display?

when doing this stuff - its really important that the monitors all play nicely together- sometimes they just dont.
especially with triple heads.

please do a screen capture showing the exact refresh rate here:
in the stats HUD.
