when using the presets and then using 'quick settings' or directly using 'custom' settings, why is there no option of "quality" when selecting codecs other than h264? only h264 has this quality option. other codecs or containers like mpeg or divx or xvid all have ONLY quantizer or bitrate option. i see that "quality" is much much better result video (small size and good quality) than using bitrate or quantizer. u need to do trial-and-error when using bitrate or even quantizer. sometimes quantizer of 2.5 gives correct result BUT sometimes for other codec 2.5 gives HUGE size of file and u need to reduce quantizer to 5 or 6, then u get small size with same quality video. this trial and error is very cumbersome. please can u give some sort of quality preset that other video converters have, like 'low' 'medium' 'high' . converting to h264 is no problem with the 'quality' preset, BUT ANY OTHER codec is a pain.
