1080 output in component, HDMI and HD-SDI,
except the HD Express, which does not supply
HD-SDI.
All interfaces provide at least sixteen channels of
simultaneous audio output. MOTU video
interfaces serve as capable video and audio I/O
hardware solutions for film scoring and post
production workflows.
Third-party video hardware
Under OS X 10.7 or later, video interfaces from AJA
Video Systems and Blackmagic Designs are also
supported.
Enabling external video hardware output
Install your video interface as instructed in the user
guide. Be sure to check www.motu.com or the
third-party manufacturer’s web site for the latest
up-to-date video driver installer. Run the MOTU
Video Setup software (or third-party video setup
utility) to ensure that the software can successfully
communicate with the hardware. Consult the video
interface’s user guide for any troubleshooting tips,
if necessary.
Once you’re video interface is running successfully,
open a movie in Digital Performer. Then, display
the movie track in the Sequence Editor (see “The
Track Selector” on page 360). In the movie track
mini-menu (Figure 32-3 on page 300), you should
now see your MOTU video interface listed by
name.
Choosing a video format
Choose the desired output format from the MOTU
video interface sub-menu as shown in Figure 32-3
on page 300.
☛ The only requirement for choosing a format is
that the frame rate of the movie must match the
frame rate of the chosen output format. If you get
an error message regarding frame rate, make sure
the video hardware is set to the same frame rate as
the format you are choosing.
If you choose Auto-Detect Video Mode, Digital
Performer automatically chooses the video format
that best matches the frame rate and format of the
current movie.
Once a format is chosen, Digital Performer
conforms the movie to the chosen output format,
adding letter box or pillar box formatting as
required to best reconcile the movie’s aspect ratio
with the chosen output format.
Turning off external video output
To disable external video output, choose No
External Video Output from the mini-menu.
External video playback offset
Some video monitors introduce a small delay
during playback, from the time they receive a video
frame to the time it actually appears on screen. The
specific amount of delay depends on the monitor,
with most devices in the range of a few frames.
Digital Performer can automatically compensate
for this offset, so that external video playback
remains frame-accurate with audio, both when the
transport is stopped and during playback. This
offset feature supports video hardware output and
FireWire video output.
To set the external video playback offset, choose
Video Output Playback Offset> Other from the
Movie window mini-menu (Figure 32-5):
