The IMAQ AVI2 Create V
I creates a new or rewrites an AVI file. Leaving the Codec
input to the IMAQ AVI2 Create VI unwired will save the file without using a codec and therefore save an uncompressed file. If the image acquired from the camera is RGB, the file saved will be an uncompressed RGB file.
The best way to see this is to modify the LabVIEW IMAQ shipping example (LabVIEW\examples\Vision\Files\AVI Codec Comparison.vi)
by removing the Codec
input on the IMAQ AVI2 Create VI.
