Can I write to two avi's at the same time?

[cjs]

I am trying to implement the IMAQ AVI Read Write Example posted in the NI Development Library. I must admit that I don't completely understand what it is doing, but it does appear to work just fine. What I need to do is write to two different avi files at the same time. What I am doing is capturing an image every set interval, doing some processing on it and writing it to an avi to be played back as a movie later. The examples I found in the Development Library work well for this (modified). Now, I would also like to write the original images (pre-processing) to a separate avi so that I have a movie of the actual images and a movie of the processed images. But I can't seem to do this using the given examples. Maybe it has
something to do with not being able to have two avi files open at the same time. I noticed that the AVI Write sub vi doesn't actually do anything with the ref num so it may not know which to write to if you try to open more than one for writing. Not sure. I would appreciate any suggestions on how I can accomplish this.

Thanks

Hello,
I believe this is possible, but it depends on the computer. ImageMill Technology makes a LabVIEW toolkit called AVI Library for LabVIEW / IMAQ Vision.
