KONA 3 Installation and Operation Manual — Understanding Typical Workﬂows

Following are summaries of the most common workﬂows, listing data rates and

relative quality levels. Some workﬂows require a RAID array and some will work

using the host Apple computer's internal system drive—it's noted where this is

supported in the following discussions.

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 an excellent compressed media choice for near 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 the quality using a slider. To be

able to effectively encode to PhotoJPEG when capturing HD, the quality slider

should not be set past 35% for HD. The quality slider can be set higher for SD

formats. KONA 3 allows for PhotoJPEG monitoring and/or output in both SD

and HD. KONA 3 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

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 3 to convert DV50 projects to uncompressed—in real time—for

monitoring and/or output. KONA 3 can capture from its SDI input, directly to

DV50 compression.
