I don't know if I understood Your problem (1): this path is appropriate?

	original-frames-*.miff
		-> images-*.jpg
			-> clip-*.yuv (0.2s = 5 f/s)
				-> movie.*** (mpeg1, mpeg2, quicktime)

sorry if this is not what You want :-)

(1) in italiano, ahime', sarebbe per me piu' facile capire e spiegare
