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?
I was thinking Gem does not support all codecs.
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
with "faster" do you mean less cpu consuming? I thought the fastest/less cpu consuming is a frame by frame codec like photo-jpeg because the gfx card can just take the jpegs and texture them onto a geo???
uyvy would be the fastest colormode,2vuy is just as efficient and better supported which is why GEM uses it on OSX.
maybe I was thinking of the isight, which uses uyvy, and a conversion slows the process down.
Apple Intermediate is more efficient than Photo-JPEG. It is fully supported by GEM.
since you are probably the only one who knows that, can you explain how gem deals with the codecs? only if you have time... I do not understand why the apple intermediate should be faster for example when using the movie as a texture for a rectangle than the frame by frame jpeg compression?
