KONA LS/LSe Installation and Operation Manual — Understanding Typical
PhotoJPEG Data rate: approximately 1-3 MB/second—supported by internal system drive
Quality: Very Good
The Apple PhotoJPEG codec offers an excellent compressed media choice for
on-line quality at low data rates. PhotoJPEG can use the full-raster at 4:2:2
sampling. Final Cut Pro allows you to adjust quality using a PhotoJPEG control
panel. KONA LS allows for PhotoJPEG monitoring and/or output in SD.
KONA LS can capture from almost any input, directly to PhotoJPEG media.
DV (DV25) Data rate: 3.13 MB/second (megabyte/second)—supported by internal system
drive
Quality: Good
In this workflow, DV is usually input to a Power Mac running Final Cut Pro
through its FireWire port. DV offers good quality, but it has lower Chroma
resolution when compared to DV50, JPEG, or uncompressed. You can use
KONA LS to playback DV projects to uncompressed—in real time—for
monitoring and/or output. Alternatively, KONA LS can capture uncompressed
from any input, directly to DV clips.
DV50 Data rate: 6.26 MB/second—supported by internal system drive
Quality: Very Good
Like DV25, Final Cut Pro also supports the Panasonic DV50 standard
definition codec. DV50 is a 4:2:2 compressed format and therefore has higher
chroma resolution when compared to DV25. Also like DV25, you can use
KONA LS to playback DV50 projects to uncompressed—in real time—for
monitoring and/or output. KONA LS can capture uncompressed from any
input, directly to DV50 clips.
Uncompressed
8-bit
Data rate: 21 MB/second (see later “Storage Capacity” chart in Chapter 1 for
transfer rates)—requires SCSI, Fibre Channel, or ATA drive array
Quality: Excellent
Uncompressed media is KONA LS’s native storage format, offering the highest
quality available. Capturing in uncompressed results in no compression
artifacts, and video is sampled over the full raster at a 4:2:2 rate. Using
uncompressed maintains a higher quality in your project from capture all the
way through effects rendering. Final Cut Pro supports realtime effects with
uncompressed media using RT Extreme. KONA LS supports capture of
uncompressed through any of its inputs, and projects are output to all of its
outputs simultaneously.
