Thanks, I am not the OP, parts of ffmpeg are bundled with the k-lite codec pack which I have for media player classic but mainly I use avidemux for simple video cuts and encoding. Probably should have mentioned that earlier but I went off on a unhelpful side-rant.
I hope you saw the ffmpeg answer by Toes below. Annoyingly it has fewer upvotes so is lower down (at least for however my viewer works).
