I would like to record a video, and then view and compare 8 still frames side by side. I would like each frame or picture to be 2 seconds apart. I don't know if I am doing this right or the easiest way, but I am using jit.qt.grab at a frame rate of 25 ms to record the video. I then want each second to be divided into four (250ms) pictures or still frames and would like to view side by side every 8th frame. I do not know how to view or capture the still frames. any advice would help!
