I'm trying to find a way to set the poster frame or thumbnail of a video (batch operation would be best) to one of the last frames for that video, say 2-3 seconds back from the end. I would prefer a default setting rather than doing it manually. Is there a way to do this on a mac or some program that is able to do this after the files are on my hard drive? I "NEED" a thumbnail of about the last 2-3 seconds of a given video. Something like, Thumb image = Total#frames - 75 frames. (for 30fps) The programming wouldn't be that hard if someone knows mac programming. I don't, bugger!!!
