SnapMotion does its job

Overcomes the problem that Quicktime7 exports .pct, which can’t be opened by Photoshop any more. Does take a little time to load source videos, but is simple to use, and the batch processing works great. You can select a bunch of pictures from a bunch of different videos and grab them all at once. Capturing can be automatic (every so many seconds/frames) or manually. Files are numbered by time - either seconds or HH:MM:SS:MS. You can set output file as .jpeg or .png and they come out in the video’s native resolution. Nice extras are that you can add a watermark and save settings for re-use later. Big problem solver.
