Capture, Preview, and Playback—Differences and Similarities
The services that KONA provides differs based on the plug-ins. Some applications, like Adobe
Premiere when used with its KONA plug-in, offer full support for media capture, previewing from
RAM, and playback to monitors and to an attached VTR with full machine control. Other
applications and their KONA plug-ins offer different levels of support. This section describes the
support provided by each KONA plug-in and the Machina standalone application and discusses
what each of these capabilities mean.
Capture Overview Capture records the source signal to your storage system from the chosen input connector(s),
digitizing and encoding the media (audio and video) to disk as you’ve directed in your KONA
configuration settings. Media may be recorded directly as configured as the Primary Format
(framebuffer) or with some type of conversion performed—a Secondary Format at the input (set
up in KONA configuration) is converted to the Primary Format (as allowed by the KONA model you
have).
For those applications that do not directly support capture via KONA, you can always use Machina
to perform the capture and then load the media into the desired application as a QuickTime, AVI,
or still image file.
Preview Overview Preview is the viewing of captured media from RAM memory in the computer. It is not necessarily
realtime since it’s affected by CPU performance and other real world factors such as other
activities that might be occuring on the host computer. RAM preview occurs on the computer
monitor. The purpose of preview operations is to review the captured material and perform
editing/trimming operations.
Playback Overview Playback differs from Preview in that the media is read directly from disk storage and output, as
configured, to KONA outputs. Playback also outputs machine control signals to the RS422
connector directing VTR operations. Playback is frame-accurate and suitable for broadcast and
print-to-tape.
