[QUOTE="ziphnor, post: 75113, member: 14215"] I had hoped that subtitles would be very distinct in that they had very few brightness levels(ie VERY bright and VERY dark) but thats not the case, some subtitle lines have just as many distinct Y levels as image lines. I have managed to produce tests that always catch subtitles but need some auxiliary sanity tests to avoid messing with the image itself. It is definetly doable, but i think most software development theory says to develop incrementally, ie build something that works with some simple functionality first, *then* improve it :) To keep the subtitles from bouncing up and down, it is best to maintain a constant(ish) box for them. When copying the subtiles i only copy pixels with a brightness over a certain threshold, so any black/gray background for the subtitles is discarded. This also means that its okay to keep a larger bounding box for subtitles than is actually used, since a frame without any actual subtitles will not copy anything. [/QUOTE]
