I have a PBG4 1.67 and a Tibook 867MHz, an Isight, and a Canopus advc

I am doing a live video performance, and I was wondering what some

suggested configurations of these would be, to get the best quality

output. What I am currently planning on is...

PBG4 1.67 running my main OpenGL patch, with the ADVC device attached

as an input device. Then on my tibook, I have the isight going in,

and then routing the composite video out and into the advc on the

Any suggestions? I also plan on having a few devices attached for control...

like a PS2 controller, and probably an Xsession, for virtual mixing.

I am open for any ideas, as I want to make this setup as efficient as possible.

If you want to remove latency, you might look at a DFG 1394, which 

brings in uncompressed video via firewire, and removes the ~ 7 frame 

latency that most ADC~ DV capture devices impose (as well as the CPU 

overhead of decompressing the DV Stream). Just a thought :)

A bit to rich for my blood, to resolve only a 7ms lag.

I wouldnt get it for audio, so I wont get it for video.

7 frames is a lot more than 7 milliseconds.

1 frame is typically 1 30th of a second, or 33.333 milliseconds. 7 

frames is 233.33 milliseconds, which is .. enough to loose 

syncopation imo. It also resolves decompression issues, it frees up 

your CPU from decoding the incoming stream.

ah, I read your message wrong. yes, 7 frames is a lot, but for the

application Im using it for, its not a problem.

But thanks for clarifying. now that device seems like a worthwhile piece.
