I need help get each single pixel's intensity in a video clip (grayscale). For example, in a video clip containing 150x250 pixels and 1000 frames, I need to obtain the intensity one by one, either row-wise or column-wise.

If you have, say, a million pixels in your video frame, you can't do a million line plots. But you can plot the average color or brightness of one, or a few, regions over time. This is what my Answer below does. Did you even see it (scroll down) or try it? If not, why not?

See my attached demo where I find the mean R, G, and B mean of every frame in a video and plot them. Adapt the region to what you need, like a single row or column instead of the whole frame.

I strongly suggest that you use all three indexes when referencing a 3-D array.
