There are, that I see, 4 programs: 1. yuvframestofields doubles the frame rate by making frames out of each field 2. yuvfieldstoframes halves the frame rate by making fields out of each frame 3. yuvntscframetopalfield takes an ntsc-rate stream (at 29.97fps) and makes it a pal-field-rate stream (at 50fps). 4. yuvflip takes an yuv4mpeg stream and flips it horizontally or vertically #4 appears interesting - not sure how much use it will see. But then mjpegtools has many niche or infrequently used programs ;) #2 though would seem to be a duplicate of 'y4minterlace' which takes a field from two frames into 1 frame and halves the rate. IF #2 is aimed at converting ~60 frame/sec progressive (720p HDTV for example) down to 720i then y4minterlace will be the tool to use. How many folks need/want #1 and #3?
