....., output movie looks promising but is garbage (some residual similarity to the original, though). No problem with encoding from YUV4MPEG. 5. (suggestion) Upgrade the frame picking algo in both FFMPEG2THEORA and PNG2THEORA: "blah(4,0).png" would mean "blah0000.png" to "blah9999.png" (as long as frame available) "frame(3,77).png" would run from 077 to 999 at most. Counter syntax: (digits, start) Using percent "%" in commandline is bad since some OS'es do use it for enviro var expansion: "SET PATH=C:\XIPH\;%PATH%"
