    Two camera fast acquisition saving

    Is it possible to acquire several minutes worth of 120 fps and 60 fps image data (from two cameras) using Labview? Currently I queue the images from each camera, but saving in real time (required or memory gets swamped) takes too long/too much processing power. The saving can't keep up and the queue gets large and crashes the 32-bit Labview program within 30 seconds.

    I am prioritizing the acquisition (image to queue) loops and saving the data in.dat binary files in batches (so saving is not called every image). Labview code is similar to this (

    Camera 1: DFK 23U618 USB 3.0 Color 480x960
    Camera 2:DMK 23UM021 USB 3.0 Mono 1290x960

    you could use AVI Capture instead of single image capture and process the AVI files later in LabVIEW. (I do not know, how to process AVI files in LabVIEW).

    The related methods for AVI capture are AVIStartCapture and AVIStopCapture.
