How do I go about this? I have access to both Mac and PC. As some background: on a PC, I used ShareX to take a small segment of a video both in terms of size and length. I had, let's say, a 1024x768 video that was 12 seconds long, and I took a 150x150 area of the video and recorded it for only 2 seconds. Then, with ImageJ, I converted the .mp4 video to a series of .tif images. Now I want to superimpose them all. I'm trying to show the movement of a cell over the course of a few seconds and I think this is the best visual representation that's not a video.
