You could try to find out what the frame rate of the camera was, then download the video and look at it frame by frame to do better. In theory, it could be spinning very fast and the camera frame rate could be almost the same so the images get slowed down (as the difference of frequencies) but that is unlikely. | |

| Sep 14, 2014 at 3:28 | comment | added | Ross Millikan | What is the purpose of the estimate? That determines how good an estimate you need. If you can't see it spin, it must be at least high tens of RPM. Unless it is carefully designed it doesn't spin a few thousand RPM, probably much less. Is that range good enough for your purposes? | |
