Issue Details

I'm writing data to an AVI file in LabVIEW and I eventually receive error -1074395965The following reason is given:
 
IMAQ Vision:  (Hex 0xBFF604C3) The AVI file has reached its maximum size of 2 Gigabytes.

Why is this occurring and what are possible workarounds?

Solution

The IMAQ AVI2 VIs in LabVIEW have an inherent 2 GB limitation that cannot be altered. Both LabVIEW 32-bit and LabVIEW 64-bit have the same capability in regards to AVI files.

If you are running into this limit, monitor the amount of data you are writing to the file using the Get File Size Function and programmatically create a new file before hitting the 2 GB limit.
