Part plea, part complaint, part feature request.
Most of my work is with greyscale video from a black/white unibrain camera. (In softVNS I can could capture greyscale and record and that was much faster.)
With jit.qt.grab I must capture 4-planes. And with jit.qt.record I must record 4-planes. And (I think) with jit.qt.movie I can only playback 4-planes. (Not sure about this without movies to test)
I would get a huge performance-boost, especially related to hard-drive if this could all just work with a greyscale setting.
I'm about to build a recorder with jit.matrixset to see if that will do me better.
been dreaming about jitter2.0. Figure that is next on your list after this live release.
