nanoFlash FAQs

So what does full-raster (1920), full-color (4:2:2), high-bit rate (100+ Mbps), compression
produce? Well, in independent tests, the results are clear: images that are visually
indistinguishable from the uncompressed HD-SDI / HDMI images directly out of your
camera! So, nanoFlash can vastly improve on the weakest link in the quality chain: your
camera’s built-in recorder.
Video/Audio I/O
5. What video input and output connections are supported on nanoFlash?
nanoFlash includes both HD/SD-SDI In and Out as well as HDMI In and out connections.
The HD/SD-SDI connections are made via a standard BNC connector, while the HDMI I/O
uses the new type C mini-HDMI connector (to save space).
6. Which video input formats are supported?
1080i59.94/50, 1080psf29.97/25/24/23.98, 720p59.94/50/29.97/25/23.98, 486i/576i
7. What is the difference between HDMI and HD-SDI?
HDMI is, in many respects, the consumer version of HD-SDI. Both HDMI and HD-SDI
transport uncompressed high-definition video and audio. HD-SDI utilizes low-cost coax
cable and is found throughout the professional video and broadcast industry. HDMI (High
Definition Multimedia Interface) utilizes a more costly 19-conductor cable, but is the
defacto interface standard for all HDTVs, consumer camcorders and now DSLRs. HD-SDI
supports cable lengths to 150 meters, while HDMI is generally limited to 10 meters
(without utilizing repeaters).
8. Is there a quality difference between HD-SDI and HDMI?
No, both HD-SDI and HDMI offer the same, high-quality, uncompressed signal from your
camera. One is not superior to the other in terms of image quality. HDMI does not
support timecode while HD-SDI does. The HD-SDI connector is also more durable and
locking, as compared to HDMI.
9. Will the nanoFlash record the HDMI output from my DSLR?
Yes, the nanoFlash could be used to record the HDMI video out of your DSLR, providing
that your DSLR outputs a standard HDMI signal. However, as of April 2010, none of the
DSLR currently available has a live HDMI output of sufficient quality for recording with the
nanoFlash. We do expect this situation to change in the not too distant future.
10. Can I connect the HDMI output from the nanoFlash to my LCD/Plasma TV?
Yes, virtually every HDTV display has one (or more) HDMI inputs, which are compatible
with nanoFlash.
11. Can the nanoFlash be connected to a DVI monitor?
Yes. You need a simple HDMI to DVI adapter to connect to a DVI monitor. Note that DVI
does not provide audio support, but you can connect the analog audio out of the
nanoFlash to speakers or headphones, as desired.
