See attached demos. One breaks apart a video into separate 2-D still image frames. Then the second one writes the image out to a text file with one line per pixel in the form (x,y,R,G,B).

Adapt as needed.

I don't want to select file but I want to run long time in folder .How I do it

[Image Analyst]

The code is designed to use a file. You have to specify it somehow.

If you want it to run a long time, put some calls to pause() in the code.
