Controlling the fps of avi when we saved the AVI video?!

[hcpark]

Hi all!

Now I am working with the webcam (logitech C920) and I am adding the AVI code in the labview example (Grab and Basic Attributes.vi) to save the video as attached file. The webcam runs well at 30 fps before starting video recording. But the fps drops sharply when I start the video recording and changes depending on the resolution of video (ex. 1920x1080: 12 fps, 1600 x 896: 15 fps, 1280 x 720: 20~30 fps). I want to record the video at constant fps (ex. 10 fps, 15 fps, ...). If you have an idea about this problem, please let me know. Thanks for all your help!

You know, this seems to be a phenomenon caused by the increased data capacity due to resolution.

The RAM memory that LabVIEW uses is limited, and I think it's a problem that happens when you try to read and record data in large amounts.

I recommend reducing video resolution or artificially increasing the virtual memory of LabVIEW.

Please note that I attached a link to use LabVIEW memory.
