It won't be out until September but the nanoFlash ($3500 U.S. list) portable HD Recorder/Player from Convergent Design sure looks interesting.
It records video, audio and time code from an HD-SDI stream onto memory cards using 4:2:2 (MPEG-2) compression. The unit measures 4.2x3.7x1.4 inches and, powered by the camera battery, consumes less than 10W.
HD Studio did an article on it.
Detailed info is on the
Convergent site.
