Write AVI crashes

[Paul_Reynolds]

I need to write image data acquired using a IMAQ PCI-1408 board to an AVI file. However, the example that I downloaded from NI (attached) crashes every time a call is made to the "AVI Write" sub-VI and, more precisely, to the AVI_write function in NI_ReadWriteAVI.DLL. This appears to occur on two separate Windows 2000 PCs with LabVIEW installed so I don't think it is anything to do with a misconfiguration of the PC.

Also, I have tried to look at the company website http://www.imagemill-tech.com/ that is referred to on the NI site. Apparently they produce AVI utilities for LabVIEW. However, the web site has disappeared. Does anyone know if this company is still in business and, if not, if another company has continued supplying their utilities.

Dear Paul,

the AVI library for LabVIEW is now available at the following link:

Paul -

I've attached another LabVIEW example of how to convert your images to an AVI file. The downside of these VIs is that we don't have the option to compress the file. Therefore the AVI files become very large, very quickly (30 frames is approximately 10 Mb).
Also, here are some links to other companies that provide more advanced AVI functions, such as compression:
