Have you seen this:

Never mind, it's the other way around.
This might help though:

Hello,
is it possible to generate AVI (video) from images without paid modules. This means using LabVIEW Base + Free modules only?
I found this article...

But I'm not sure if IMAQ driver is for free or I need to buy at least Vision Acquisition Software

OpenCV can both capture video's and create AVI files. It's free, but not that easy to get working. My library isn't good enough to share, but I've used OpenCVSharp's OpenCV dll (the normal dll that .NET uses). There are OpenCV libraries for LV dangling around. I hope dlls\.net are supported in LV Base...
IIRC, IMAQ requires a runtime license, but comes with NI Vision. Maybe you can legally use IMAQ for free, but the Run-time license is just as expensive as NI Vision, that doesn't require a run-time license. Something weird like that was going on. Please check the details yourself.
