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.
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. 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.”

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.

a 2K Workflow
Data rate:
For 2048x1556 2K:
• When seen as a QuickTime movie at 23.98fps with a raster of 2048x1556, the data rate is
300MB/second (approximately).
• When seen as a single frame DPX file with a 2048x1556 raster, the size is roughly 12+MB/
frame.
• 2K uncompressed media necessitates the use of high-performance SCSI
or Fibre Channel drive arrays.
Quality:
Excellent, with additional cost and labor savings over traditional 2K workflows.
