Convergent Design's Nano Flash SD/HD Recorder.
This SD/HD recorder will set you back a couple grand but if you have the cash to spare, this little gem could be worth every penny. The Nano Flash records directly from the HDMI output, giving you uncompressed 4:2:2 images. It will also let you record in multiple formats such as Native QuickTime for FCP, and MPEG HD with real time rendering of Blu-Ray Discs. The nanoFlash can also increase record times in HD DSLRâ€™s with two hot swappable CF card slots.
The nanoFlash will also record 24-Bit/48K uncompressed audio, with two channel level meters and a headphone out to satisfy the sound geeks out there.
