PLAYBACK AND MONITORING

To play back your Premiere Pro project and view it
on any monitor or other device connected to the
HDX-SDI's video outputs:
1 Choose Edit menu > Preferences > Player
Settings.
2 Choose the MOTU HDX-SDI as the Default
Player (Figure 7-10).
This allows you to view the Source window on any
monitor connected to the HDX-SDI's video
outputs.
3 Start playback.

Native versus non-native clips
Clips that match the native video format of your
Premiere Pro project and don't require any further
rendering will play back. Clips that don't match the
native video format of your Premiere Pro project
will appear in the time line with the red render bar.
For example, if you place an HDV clip in the time
line, it will appear with a red render bar. In this
case, it will likely not play smoothly, unless your
computer is fast enough to transcode it in real time
during playback (see "Mercury playback engine"
below). For smooth playback, render the clip to
convert it to the native video format for your
project.

Mercury playback engine
The HDX-SDI take full advantage of Premiere Pro's
Mercury playback engine. If your system is
equipped with a Mercury-enabled video card, you
will enjoy industry-leading rendering speeds.
Consult your Premiere Pro documentation for full
details.
The HDX-SDI does not require any additional
configuration or settings to support the Mercury
engine. If you enable Mercury as explained in the
Premiere Pro documentation, the HDX-SDI will
take full advantage of the engine.

AUDIO HARDWARE SETTINGS

Choose MOTU PCI Video ASIO as a Default Audio
Device (Edit > Preferences > Audio Hardware) to
ensure that audio and video stay in sync during
playback (Figure 7-11).

Two 8-channel banks of audio
The HDX-SDI provides two 8-channel banks of
simultaneous audio input and output: Bank A
(channels 1-8) and Bank B (channels 9-16). Use
the settings in the Audio tab (Figure 6-11 on
page 43) to assign the desired audio formats to
each input and output bank.
