CompactFlash HD/SD SDI and HDMI Recorder/Player
nanoFlash is the world’s smallest, lightest, lowest-power,
professional HD/SD recorder/player
Easily mounted to your camera, nanoFlash is designed to record
higher quality images than the camera itself, by capturing
never-compressed video/audio from the HD-SDI or HDMI output.
nanoFlash utilizes the very high-quality Sony XDCAM 422 CODEC,
recording the video/audio onto affordable Compact Flash Media, at
visually lossless rates up to 160Mbps (Long-GOP) or 220 Mbps
(I-Frame). The footage can be stored in either Quicktime (MOV), MXF,
or MPG file formats, providing near-universal NLE support as well as
DVD / Blu-Ray authoring formats.

Will nanoFlash
improve the image quality of my existing camera?
Three major components largely determine the ultimate video quality
from your camera: the lens, the CCD/CMOS sensor, and the built-in
recorder. Some cameras do offer interchangeable lenses, so you may
have the option to upgrade over the standard issue. The CCD/CMOS
sensor is fixed on all cameras and cannot be modified. However, all
HD-SDI and HDMI cameras allow users to upgrade the recording
subsystem, which can yield significant improvement at reasonable
costs. It’s really quite simple, but let’s first discuss the problem
with your built-in recorder.
Your camera’s recording subsystem has two major components: the
CODEC and the storage device. The CODEC compresses the video from
about 1,200 Mbps (uncompressed HD) to a more manageable 20 to 220
Mbps. The storage device is typically a tape, optical disk, or
possibly a memory card. Compressed video, along with audio and
timecode, is stored on these media for playback or transfer to a NLE.
The CODEC and storage medium are both significant in determining
your video quality. In general, the higher the compressed bit-rate,
the better the video quality. However, most storage media severely
restrict the possible data-rates. Mini-DV tape (used in HDV
cameras), for example, has a fixed read/write bandwidth about 25
Mbps; SDHC memory cards are limited to about 45 Mbps. So, the
ultimate data-rate from the CODEC must be restricted to match the
performance of the storage medium.
The level of sophistication and implementation of the CODEC play a
major role as well. I-Frame only CODECs, in general, require two to
three times the bit-rate to equal the quality of the more
sophisticated Long-GOP CODECs. (100 Mbps I-Frame is roughly
equivalent to 35 Mbps Long-GOP in overall quality). Most CODECs, (HDV,
DVCPro HD, XDCAM EX, and even HDCAM) also reduce the potential
quality through color-sample decimation (4:2:2 → 4:2:0 or 3:1:1)
and/or by horizontally sub-sampling (1920 → 1440 or 1920 → 1280).
The Solution: nanoFlash - High-Bit Rate, Full-Raster,
4:2:2
The nanoFlash overcomes these quality-robbing restrictions in your
camera. You connect to the HD/SD-SDI or HDMI camera output (in live
mode) to send “never-compressed” video directly from the CCD/CMOS
sensor to the high-quality CODEC and then to the high-speed digital
storage (CompactFlash cards) in the nanoFlash.
Since nanoFlash records on CompactFlash solid-state memory, (as
opposed to tape, optical disk or SDHC cards) the bit-rate can be
substantially increased over your built-in recorder.
nanoFlash features a sophisticated high-quality Sony XDCAM 4:2:2
(MPEG2) CODEC with data-rates up to 160 Mbps in Long-GOP mode (I,P,B
Frames), and up to 220 Mbps in I-Frame-only mode. The CODEC
compresses the video without reducing the color sampling (full
4:2:2) and without sub-sampling the horizontal data (full 1920).
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.

| Why Nano Flash Recorder? |
|
1.Enable a camera with Tape recording mechanism to record in a Tapeless format
2.Record in 4:2:2 from HDMI or HDSDI output of camcorder
Camera Codec
Reference: MPEG-2 Color Sampling
Color sampling refers to selectively extracting information by skipping the color difference signal of some pixels. Applying the principle that the human eye is more sensitive to brightness than hue or saturation, sampling compresses signals by eliminating some pixels from the color difference signals to be read.
The color sampling scheme indicates how many pixels out of a four-pixel area (two pixels vertically by two horizontally) are used as brightness and color difference signal information.
In
4:2:0 color sampling, B-Y (Pb) is read in odd rows of pixels and R-Y (Pr) in even rows. Only information of one pixel out of the four-pixel area is read for B-Y (Pb) and R-Y (Pr), but this scheme is identified as 4:2:0 to distinguish it from 4:1:1 sampling.
3.Allow external audio inputs
4.Reliable recorder in a high vibration application ( Race Cars, Airplanes, helicopters etc)
5.Cost saving in the long run...
6 x 32G CF cards is under USD1500 + 1 Convergent Design Nano Flash (USD2995) = USD4495
6 x 32G P2 cards is USD3600
6 x 32G SxS Cards is USD4800
(more expensive as compared to 1xNanoFlash + 6 x 32G CF cards)

NanoFlash Immediate Benefits |
|
|
Building on the success of the award winning Flash
XDR, Convergent Design now offers the highly
anticipated nanoFlash.
The nanoFlash offers most of the capabilities of the
Flash XDR, plus some new features of its own, all in
a compact size.
For most cameras with HD-SDI or HDMI outputs,when recording in-camera, you are losing quality.This is true of the EX1/EX3 series, XL H1 series,XH G1, and most other tape or disk based cameras.And this is true for many pro cameras also.
Your internal recording may be 4:2:0 while the HDSDI
or HDMI outputs are 4:2:2, which is dramatically
better. The nanoFlash can improve your images by
recording the high-quality 4:2:2 signals.
All of the image quality of the Flash XDR plus HDMI
inputs and outputs are included in the nanoFlash.
The HDMI output allows for on-set monitoring and
playback using a quality HDTV, and playback off-set
is now practical wherever an HDTV with HDMI is found.
The nanoFlash records from HDMI equipped
cameras, as well as cameras with HD-SDI.Regardless of the input signal type, both HD-SDI and
HDMI outputs are available for use simultaneously.
The nanoFlash also functions as a standalone HDMI<>HD-SDI converter.An advanced Sony Codec is used in the nanoFlash to produce the same stunning
images as the award-winning Flash XDR.
The images are recorded, Full-Raster, 4:2:2, at 50 or 100 Mbps Long-GOP,
which has
been proven to provide outstanding quality, while maintaining a manageable
file size.I-Frame only formats, at both 100 and 160 Mbps, are available as a menu
option.
You can record in native Quicktime or native MXF and a program is provided
to convert formats
.The nanoFlash records to low-cost, highly reusable, CompactFlash cards from
many manufacturers;Transcend, SanDisk, Lexar and others. Quality 32 GB CompactFlash cards Low
cost, high performance,
card readers are widely available.
With the nanoFlash, you can instantly achieve the benefits of a tapeless
workflow. Tape dropouts and
real-time (1x) captures are a thing of the past. Instant, on-set review of
your footage is now possible,allowing you to ensure that your shot is perfect.
For longer recording times, for use with the original Canon XL H1 and POV
cameras, for externalprofessional XLR audio I/O, and for uncompressed support, the Flash XDR is
your best choice.If compact size is your first priority, choose the very capable nanoFlash. |
