A colleague asked me if this was possible the other day, to take photo stills from say a film  (in his case of diving) and have them to put on say Facebook. I couldn’t find what I used last time I did it, but did find this and have been reliably informed that it works, it produced an image of about 1MB (I didn’t check the resolution) – I’ve got a few that I’d like to extract so will give it a go when I get a chance!
