thanx.
figured out the rescaling. i forgot to nest.
one more question. my media comes from ntsc dv and some stills. graphics are imported into fcp uncompressed. i copy the media into a 720×480 timeline with 8 bit uncompressed 4:2:2 compression, best motion filtering. render and export timeline with current settings. import it into FCP, put into 8 bit uncompressed 4:2:2 PAL timeline and apply the G Converter.
am i doing the best possible quality conversion?
