DVCPRO HD

Data rate:

6 to 14 MB/second high definition—supported by internal system drive

Quality:

Excellent

KONA 3G has hardware support that allows capture from HD-SDI to the DVCPRO HD codec.
KONA 3G'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 3G 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/second 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 3G supports capture of uncompressed through its SDI input. Uncompressed
media can output via all of the KONA 3G 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.”

Log RGB and RGB
Codecs

Data rate:

200 to 300+ MB/second high definition and 2K; 4K 200 to 850MB/second

Quality:

Excellent, highest quality available

Offering all the benefits noted previously for 10-bit uncompressed 4:2:2, Dual Link 4:4:4
video using 2 HD-SDI channels and 3G 4:4:4 using one SDI channel provide full-color
resolution and 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.
