check out the function jump() of the video library in the reference. it allows you to jump to a specific portion of the video. after going to a specific frame you can read its pixels[] and manipulate it to be displayed the way you want. for this it would probably be good to create another array to which you transfer the movie.pixels[] and from that newly created array you can manipulate each frame and finally print to the screen either using the pixels[] or creating a PImage and outputting it with the image() function.

furthermore:
you could export a jpg sequence of the video you want to use and read frames individually by accessing the images, for example.

you could even use processing, for example to export each frame as an image and, after doing so, you could retrieve each frame separately.
