AJA Ki Pro Rack - Manual (Page 32)

Ki Pro Rack v4.2 www.aja.com 32
NOTE: You cannot select HDMI audio unless you have an HDMI video source, nor can you select an
SDI audio source if you have not selected an SDI video source. If you attempt to mismatch
these settings, a warning will alert you to the mismatch on the front panel.
These are just a few menu parameters that you might wish to change before you make
your recordings. To learn all the ways to convert formats on input or output read the
CONFIG menu and MEDIA menu parameter topics later in this chapter.
Recording Notes • Ki Pro Rack may take a few seconds to close longer files (files over 20 minutes). For
these longer recordings, you may see a "Closing File" prompt on the display.
• Ki Pro Rack alerts you when the media is nearly full with a "Media Low" prompt at 15%
of the remaining capacity. At 10% of the total capacity of the media, the "Media Full"
prompt will appear. Any recordings that have been started will stop once 10% is
reached and no further recordings can be performed using this media until it is
formatted again or a MEDIA>Delete Clips>DELETE ALL has been performed. Deleting
clips to produce more than 10% free space will allow recording to resume.
• To change Apple ProRes 422 settings prior to recording: press MEDIA, and then
repeatedly press SELECT until you see 14.1 Encode Type. Next, press ADJUST up or
down to select "ProRes 422LT", "ProRes 422PX", "ProRes 422HQ" or "ProRes 422". Press
MEDIA or STOP to exit the menu. To change to Avid DNxHD, select 14.0 Encode Mode
in the MEDIA menu; use the ADJUST up button to select "DNxHD", and then ADJUST up
again, and hold ADJUST up for two seconds to reboot for DNxHD. Once the Ki Pro Rack
system is rebooted, navigate to 14.1 Encode Type and press the ADJUST up or down to
select "DNxHD 220x", "DNxHD 145" or "DNxHD 36" (if using 1080p).
Playing Back a Clip
To playback recorded media, you simply select the clip desired and press PLAY. If the clip
you wish to playback is not currently selected, use the SELECT up/down buttons until the
clip name appears on the display. Like recording, there is more than one way to initiate
playback (front panel, web browser). From the front panel these are the basic steps:
1. Press the STOP button to get to the TRANSPORT mode (if not already there). Find the
clip name in the display (it shows the current clip/reel).
2. Press the SELECT up or down arrow button repeatedly until you find the clip you are
looking for.
3. Press the PLAY button (>).
4. When playing back a clip (PLAY, FF, or REV) the first push of STOP acts as a “Pause”
mode: the playback is paused, the current point of the clip is displayed, and the STOP
button will flash. A second push of STOP will completely stop the playback and Ki Pro
Rack's outputs will go into an “E to E” mode (the currently selected inputs will be
bypassed to the outputs). When a playback reaches the end of a clip, it will
automatically pause on the last frame of the clip.
During playback you can use the FFWD, REV, SELECT, or ADJUST buttons as follows:
FFWD >>: Press button to begin fast playback of the current clip at 2x speed. Successive pushes
increase the speed to 4x, 8x, and 16x. (Pushing the button after 16x speed is reached has
no further effect.) When fast-forwarding, audio is muted.
REV <<: Pressing REV when not lit, begins playback of the current clip in reverse at 1x speed.
Successive pushes increase the speed to 2x, 4x, 8x, and 16x. (Pushing the button after 16x
speed is reached has no further effect.) When playing in reverse, audio is muted for all
speeds.
