KONA 3 Installation and Operation Guide — Understanding Typical
PhotoJPEG
Data rate: approximately 1-3 MB+/second standard definition or high definition—supported by
internal system drive
Quality: Very Good
The PhotoJPEG codec offers excellent compressed media for near on-line quality at low data
rates. PhotoJPEG can use full-raster 4:2:2 sampling. KONA 3 allows PhotoJPEG monitoring and
output in both SD and HD and can capture from almost any HD or SD input, directly to
PhotoJPEG media.
DV (DV25)
Data rate: 3+ MB/second (megabyte/second) standard definition only—supported by internal
system drive
Quality: Good
DV is commonly input to an Apple computer via FireWire. KONA 3 can capture directly to DV
compressed media from an uncompressed SDI source. For devices that may not have FireWire
(IEEE1394 or i.Link) connections, this allows the user to capture to this low data rate, yet good
quality codec. While DV does offer good quality, it has lower chroma resolution when compared
to DV50, JPEG, or uncompressed. The KONA 3 can be used to convert DV projects to
uncompressed-in real time-for monitoring and/or output even if you haven't captured the
footage using the KONA 3.
DV50
Data rate: 6+ MB/second standard definition only—supported by internal system drive
Quality: Very Good
Panasonic DV50 standard definition codec. DV50 is a 4:2:2 compressed format and has higher
chroma resolution than DV25. As with DV25, KONA 3 can convert DV50 projects to
uncompressed, in real time, for monitoring and output. KONA 3 can capture from its SDI input,
directly to DV50 compression.
