here is my story so far:
I have experienced that using a wrong codec or color mode can strongly
affect the cpu. even if you are on a mac, gem does not support all the
driver features of other mac native programs (as far as I know).

Like what features?

the
fastest codec for me was fotojpeg.

There are many more efficient codecs but most are specific to a standard. DVCPro-HD at 1080 or 720 is far faster than P-JPEG

uyvy would be the fastest colormode,

2vuy is just as efficient and better supported which is why GEM uses it on OSX.

but I think that is not supported on gem too, and not at all on
non-macs. the apple intermediate codec seems to be almost fotojpeg, but
if not supported by gem still a codec that has to be reencoded to be
playable within gem.
otoh that will increase your filesize even more...

Apple Intermediate is more efficient than Photo-JPEG. It is fully supported by GEM.

marius.
