AVoption & AVoption XL Guide38
To record video:
1 Use your cursor to mark the point from where
you want to start recording, or to select a range
of time for the recording. You can make this se-
lection on a Timebase Ruler or on a track. If you
make this selection on a track, make sure that
Edit and Timeline selections are linked.
2 Record enable the track by clicking the Record
Enable button.
3 Click the Record button in the Transport win-
dow to enable recording.
4 Start playing the video source.
5 Click Play in the Transport window to begin
recording.
6 Click Stop in the Transport window to stop re-
cording.
MachineControl
You can use Digidesign’s MachineControl soft-
ware to remotely control your external video
deck in sync with your Pro Tools capture. Ma-
chineControl is optional software. Contact your
dealer for more information.
Blocks mode is recommended when recording
to the Movie track with MachineControl.
Timebase Correction
Most professional video decks have built-in
timebase correction. To find out whether or not
your video deck has built-in timebase correc-
tion, refer to the manufacturer’s documenta-
tion.
AVoption XL requires that all sources be time-
base corrected.
AVoption allows you to capture
video from sources that are not timebase cor-
rected. However, it is recommended that you
use timebase corrected sources whenever possi-
ble.
If you are manually capturing video in AVop-
tion that is not timebase corrected, start play-
back of the video deck first to stabilize the sig-
nal. If your configuration does not feature time-
base correction, make sure that your sync
generator is connected to the external sync or
reference video input on your video deck, and
that the deck’s sync selector is set to “external
sync” or “reference video.”
Capturing with Stationary
Playhead
If you want to capture video with Scrolling Op-
tions set to “Continuous Scrolling with Play-
head,” AVoption should always be set to Blocks
mode (as opposed to Frames mode) to avoid per-
formance errors.
Capturing and Approximate Time
Left
The approximate record time left in the I/O
View of the Movie track is an estimate. AVop-
tion and AVoption XL use variable compression
technologies, and record time varies based on
the density of the material you are recording.
Note that if there are already clips on the
Movie track, and you record over them, the
overwritten material will be removed from
the Movie track (although it will still re-
main intact in its original storage location).
You can Undo Capture Clip and restore the
original clips.
Refer to “Undo/Redo for
Video Editing Commands” on page 42 for
more information.
Command+period (.) will abort a clip cap-
ture in progress and restore the Movie track
to the original clips.
