DVCPRO HD Data rate: 6 to 14 MB/second high definition—supported by internal system
drive
Quality: Excellent
KONA 3 has hardware support that allows capture from HD-SDI to the
DVCPRO HD codec. KONA 3's hardware also takes a portion of the DVCPRO
HD codec processing load off the CPU, allowing more computer processor time
for Dynamic RT effects in Final Cut Pro.
HDV Data rate: 2+ MB/second high definition—supported by internal system drive
Quality: Very Good to Excellent
While the structure of HDV (Long GOP MPEG2) makes it nearly impossible to
ingest in realtime, you can use KONA 3 to convert HDV projects to
uncompressed-in real time on playback-for monitoring and/or output.
Uncompressed
8-bit 4:2:2 (SD or
HD)
Data rate: 21 MB/sec for standard definition or 100 to 125 MB/sec for high
definition—external storage recommended
Quality: Excellent, broadcast quality
Capturing in uncompressed results in clearly defined video, at full raster size and
4:2:2 chroma sampling. Using uncompressed maintains high quality from capture
all the way through effects rendering. Final Cut Pro supports RT with
uncompressed media using RT Extreme. KONA 3 supports capture of
uncompressed through its SDI input. Uncompressed media can output via all of
the KONA 3 outputs simultaneously.
Uncompressed
10-bit 4:2:2
Data rate: 28 MB/second standard definition, or 133-166 MB/second high
definition
Quality: Excellent, broadcast quality
Offering all the benefits noted previously for 8-bit uncompressed, 10-bit
additionally offers higher color specificity for compositing and color correction.
With Uncompressed 10-bit 4:2:2 media, video quality is second to none-at any
price point - for non-linear post production. For more information on this
subject, please see the topic at the end of Chapter 4: Installation and
Configuration, titled “Using 8-bit Versus 10-bit Video.”

Codecs
Data rate: 200 to 300+ MB/sec - high definition and 2K
Quality: Excellent, highest quality available
Offering all the benefits noted previously for 10-bit uncompressed 4:2:2, Dual
Link 4:4:4 video uses 2 HD-SDI channels to provide full color resolution as well
as luminance. The term “4:4:4” refers to the ratio of sampling frequencies used to
define the RGB components of a video signal. In this ratio, the red, green and
blue components receive equal specificity, providing increased quality over 4:2:2
where chroma sub-sampling occurs. 4:4:4 is particularly useful for film related
digital intermediate work as well as the highest level compositing and color
correction.
