AJA Ki Pro - Manual (Page 64)

Ki Pro v3.2 www.aja.com 64
NOTE: Ki Pro 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 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 video tape where you might not have sufficient pre-roll
to ingest a take into a non-linear editor, Ki Pro 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 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 behaves like a tape recording
and a traditional VTR. Like a tape recording, Ki Pro will display continuous timecode for
clips that were recorded one after another, but Ki Pro 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, 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 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.
Since Ki Pro has a default state of E-to-E when stopped, if both the input and output of a
non-linear editor are simultaneously connected to Ki Pro, you may then need to begin
playback on Ki Pro to produce a clean picture. After this initial playback happens under
remote control, subsequent playback and stop/pause will appear as expected as Ki Pro
will not re-enter the E-to-E state.
Due to the fact that Ki Pro is file based, when shuttling across clips at high speed, a "hop"
may be visually perceptible as files close and open; this does not compromise the
operation of Ki Pro under RS422, but may seem different from how a tape-based VTR
would respond under similar conditions.
AJA recommends the following for use with Apple's Final Cut Pro 7>Edit to Tape and
Avid's Media Composer>Digital Cut:
• Only connect the output signal of the NLE to the Ki Pro to avoid the possibility of an EE
feedback loop; if the input and output of both the NLE and the Ki Pro are connected
and EE is entered, a feedback loop may occur.
• To avoid potential cueing errors during pre-roll for an edit, it is recommended that
prior to attempting the layback, the Edit to Tape or Digital Cut windows show
"00:00:00:00" for the timecode value; this means that the Ki Pro is in a "full stop," which
is indicated by a solidly backlit STOP button on the front of the unit as opposed to
"pause" indicated by a flashing backlit STOP button.
