Problem creating an AVI file of an intensity graph using only "Vision Aquisition Software 8.2.3"

[xunjian]

Hello,

My LV application obtains an intensity graph from an IR camera. I want to create a simple uncompressed(if you know how to compress it, please help as well) AVI file of the intensity graph. I downloaded the free Vision Aquisition Software 8.2.3 which seems to be able to do the job from its documentations. However, when I play the AVI file that I obtained with Windows Media Player, it only shows a black background with few white dots appearing randomly near the top edge of the movie.

I have attached the LV file that I have been using below.

From my research so far, I found out that most likely the error is caused by the lack of "IMAQ ArrayToImage.VI" which is supposed to be wired at the place indicated by the arrow in the picture below. I understand that this .vi file does not come with Vision Aquisition Software. Therefore I have 2 questions. Is there anywhere I can obtain that one "IMAQ ArrayToImage.VI" file without having to purchase the entire Vision Development module package? Alternately, is it possible to capture an AVI movie of the intensity graph using only elements from the Vision Acquisition Software? If so, I will greatly appreciate it if you can show me how.
