Continuos acquisition video and record video in AVI format

Question

Hello,
I want to make a continuos acquisition of video with a webcam and record video in AVI format with a number of frames per second equal to 60, and with a possibility to choose the period of acquisition in the window '' front panal '' but the problem is that when I selected an acquisition time of 1 minute supervision
video takes a time of 1 minute but I get an AVI video recorded with a duration of 15 seconds !!

I'm sorry, you didn't understand what I wanted you to do.  You might have "done the right thing", but I can't be sure.  Your original program (as I understood it) recorded images from the camera for a fixed period of time that you set (so you knew the recording time) -- what I wanted to know for the original camera was (a) what was the recording time and (b) how many frames were taken.
The second program that you just attached does the opposite -- it records a fixed number of frames (a better way to do this is to use a FOR loop and just wire 900 to N in the upper left hand corner).  If you are going to record a fixed number of frames, then I want to know how much time it takes to record.  You can do this by doing something like what is shown below (with the FOR loop example).
I realize that this is in the "wrong" version of LabVIEW, but it just involves adding two Tick Count functions to your Camera loop.  If it does say that Delta-t = 15000 (15 seconds), then the main question, "Is the camera recording at 60 FPS", is answered as "Yes".  In any case, we should have enough data to make your code work as you want it to.
