Issue Details

I have a LabVIEW project where I snap/grab an image/video, display it, and then save it using NI-IMAQ. However, whenever my LabVIEW program is at the "save image/video" step, I get the following error:

Error -1074395992 occurred at IMAQ WriteImageAndVisionInfo
Possible reason(s):

File access denied.

 

Solution

The error -1074395992 is mainly related to the file path configuration. When dealing with this error there are a couple of things to double-check:
  1. Check that you have permission to write to the directory specified in the file path of the IMAQ Write Image and Vision Info.vi or IMAQ AVI2 Write Frame.
  2. Make sure you're including the file path as a file extension you're saving (.JPG, .TIFF, .PNG, .AVI). You can look at the examples Snap and Save to File.vi or Grab and Save to AVI.vi on NI Example finder (Hardware Input and Output > Vision Acquisition > NI-IMAQ > File Input and Output)
