Like what features?

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

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