[jitter] [OT] Convert videos to grayscale

generalizing, any codec that compress video NOT as rgb (or argb) will give
you better results. like yuv colorspace http://en.wikipedia.org/wiki/YUV
some codecs support both colorspaces. see the link for more info. but its
always better to just try. also quicktime is very picky about what codecs it
will prefer. beter test before.
the 1 plane\4 plane is a jitter convention
