Hi, Im reading in an existing video file and then analysing each frame for when an led comes on. This will be done using histograms or intensity methods. The problem i have is that it does this in real time. As in when i run the program it will pull each frame and analyse at the frame rate of the video. Ideally I would like to do this as fast a possible instead of waiting the 10 or so seconds it takes for the LED to come on. In short I would like to know how to read the frames faster than the frame rate, and analyse these so that I can find the frame of interest? Thanks for any suggestions.

I just tried to implement it but using histogram instead of light intensity and it made no difference. not sure why. I may have done it wrong

for use of example that I send to you
use number 2 or 3 for frame multiply number in that vi
also using RGB histogram for this one is not good method and it could consume time
