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 uncompressed produces clearly defined video, at full-raster size and 4:2:2 chroma
sampling. Using uncompressed maintains high quality from capture through effects
rendering. Final Cut Pro 7 supports RT with uncompressed media using RT Extreme. KONA 3G
supports capture of uncompressed media through its SDI input. Uncompressed media can be
output from 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 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.

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, and
• 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.
