how to write 3 AVI files from 3 different cameras connected to 3 PCI 1411's?

I have a multiple camera acquisition vi and a AVI read/write vi, but I want to acquire from 3 cameras and write 3 AVI files simultaneously. The multiple camera vi uses buffers but the AVI read/write vi does not(I think). How can I accomplish my goal?

Your best bet is to use the new IMAQ Vision 7, which was released last Tuesday, I believe. It now has native support for writing compressed AVI movie files. These VIs are used the same way the Write BMP.vi and other file I/O VIs are used in IMAQ Vision 6.1.

Writing 3 files simulateously should be fairly straightforward. If you can get it to work with one camera (img0), then just copy and past the code two more times for img1 and img2. Also write to three different AVI files. That's all you should have to change! Bandwidth to the harddisk may be another matter all together...

Where can I find the new IMAQ Vision 7? I looked on the NI ftp site but did not find it.

It hasn't been officially announced, but the new Vision 7 can be purchased. I recommend going to the Upgrade Advisor (http://www.ni.com/advisor/). It will step you through the process.

Cheers!
