How to write an .avi from .tif's stored on harddisk

[Rogier Nap]

I have looked at the avi readwrite example but this example is set up to be used with IMAQ hardware. I don't understand the structure of the nireadwrite.dll and how to use it properly.

Does somebody have a better example for me?

Hello Rogier,

The VI that you are using is acquiring images from an IMAQ HW device, and then converting those images into a 2D array. You just need to exchange the IMAQ Acquire with an IMAQ read file from disk VI, and then feed that image to the "IMAQ ImageToArray".

Hope this helps,

I have tried this approach with no success. Everything appears to work fine as I create the AVI file (i.e. the images look okay in the IMAQ window and the file does get created). However when I use the AVI Testread example to view the file I get a window of zero size. When I try to view it using Windows media player I get the following error: "No combination of filters could be found to render the stream"
One thing I have wondered about: The example TestWrite AVI program I downloaded from this site opens with a bad wire between the property node and IMAQ Create.vi. Is this issue due to my using Labview 6.1?, and is my problem with AVI files related?
I would appreciate any suggestions you can offer.
