We've been wanting to be able to save images on the screen to VHS tape, and have found several hardware options. One we're looking at is a converter box that will take in RGB signals and output S-Video and Composite. We'd prefer this one over a genlock card since the same box can be used on other equipment in the lab. My question is this: I've been unable to find complete specs for the RGB video on the Iris. I know that it is 75 ohm with sync on green, but can't find the peak to peak voltage. Here is what the converter box will handle: RGB Input: Option to sync on green Connector: BNC input with BNC loop-through Impedance: 75 ohm or High Z Input Level: 0.714 Vp-p The converter is called VIDI/O Box from Truevision. The Vidi/o box will work with standard RGB signals. Does anyone know if the SGI outputs standard RGB. If you know if this is ok, or have heard rumor of someone using this without blowing up their computer, please tell me. Tom Benedict benedict@chaos.utexas.edu

SGI sells the VideoCreator which performs scan conversion of the hi-res screen down to either NTSC or PAL resolution. The VideoCreator is compatible with the SGI RGB output. In addition, the VideoCreator provides Video Local Area Network (VLAN) support. Baron Roberts ASD Video Software
