Remote Control - AJA Ki PRO rack Operation Manual

35.2 REMOTE CONTROL

IMPORTANT:
Ki Pro Rack v4.2
Enables or disables Ki Pro remote control by an external device. With the RS422 selection,
an external RS422 controller or an NLE may be used to control the Ki Pro. These are the
available options:
Local Only (default)
RS422 Only
The CONFIG menu parameter 8.0 TC IN is set automatically to correspond to the RS422
Only. When the 8.0 TC IN is set to RS422, it allows Ki Pro Rack to accept an RS422 in-point
timecode value as the beginning timecode value for the recording. Example: the value
01:00:00:00 is received as the in-point; this becomes the first frame of the Ki Pro
recording.
NOTE: Ki Pro Rack can be used as a player or a recorder under RS422 operation, but when used as a
recorder, Ki Pro Rack can only perform assemble edits, not insert edits. This means that Ki Pro
Rack creates a new file for each assemble edit performed; Ki Pro cannot insert into an existing
file.
Ki Pro Rack can operate on a solitary clip under remote control or all of the clips on the
Storage Module. Whether one clip or all clips are active under RS422 is determined by the
MEDIA menu parameter 15.1 Play Media.
Ki Pro Rack may react erratically if invalid clips or media are present and 15.1 Play Media "All"
is selected.
NOTE: Ki Pro Rack RS422 device control under a single clip is designed so that the clip may be
obtained in its entirety via non-linear capture. This is made possible because Ki Pro Rack
produces video black/silence prior to the first frame of video for the single clip and after the
last frame of video for the single clip. This means that unlike videotape where you might not
have sufficient pre-roll to ingest a take into a non-linear editor, Ki Pro Rack allows you to
obtain the whole clip by marking the in-point for ingest as the very first frame of video
recorded.
If MEDIA parameter 15.1 is set to "All", Ki Pro Rack allows the playback of all clips on the
Storage Module in the order they were created, but does not allow for video black/
silence prior to the first clip or after the last clip recorded. In this way, Ki Pro Rack behaves
like a tape recording and a traditional VTR. Like a tape recording, Ki Pro Rack will display
continuous timecode for clips that were recorded one after another, but Ki Pro Rack will
also display timecode for clips that might have been recorded with differing or non-
continuous timecode values. In such cases, the user must be aware of the timecode
changes and log and capture material accordingly, just as would be the case if using a
videotape with discontinuous timecode.
There are other important considerations when working with Ki Pro under remote
control. When media is mounted in Ki Pro Rack, the most recently recorded clip is
displayed. If using the MEDIA parameter 15.1 Play Media in the "All" selection, this is akin
to having a videotape inserted into a VTR "tail out" and not rewound. Also note that if
using the 15.1 Play Media parameter set to "One", the clips would need to be stepped
through manually via the Ki Pro Rack front panel Select up/down arrows or via the web UI
via the Transport page with the same Select up/down arrows to move between clips that
are to be controlled.
