hi roger,
thanks for your explanations. sorry that i didn't include my encoding
options. that sample i provided was encoded with following options:
basic:
dual-pass
dual pass goal: best quality
advanced:
half pixel motion: checked
four vector motion: checked
mpeg quantizer (asp): not checked
adaptive quantization: not checked
pure mp4 video: not checked
vopn coding: not checked
so you're right and that sample was no advanced simple profile content.
in any case the simple profile content that is created by 3ivx delivers
probably the best quality for the quicktime player without any
additional codecs installed.
can't wait for your results of the comparison with the squeeze encoder.
do you think that diva delivers better quality than quicktime pro or is
it just easier?
