Chapter 4 Recording clips
About recording clips
The Player/Recorder application requires a player/recorder channel. The application
has two views— Control view and Cue view. The Control view allows you to record
clips. The Cue view is used to add, remove, or rename cue points within a clip and
create new subclips.
Select record channel signal inputs – Before you start recording, you might need to
select video, audio, and timecode inputs.
Missing or intermittent timecode
• If VITC, LTC or ANC is the selected timecode source and the signal is missing,
the current timecode display shows XX:XX:XX:XX while the clip is being
recorded. After the recording has finished, the clip is automatically re-striped
starting from 0. Also, clips recorded without timecode will show no mark-in/
mark-out timecode after recording.
• When VITC or LTC is detected, but the signal is intermittent, the display shows
XX:XX:XX:XX any time the signal disappears. Clips with missing or intermittent
timecode will show this behavior during playback in a play channel.
• If VITC or LTC is intermittent, try one of the following solutions:
• Use the internal timecode generator as the timecode source for recording.
• Stripe the timecode after the clip is recorded using the Recorder/Player
application.
Re-recording and appending clips is not supported through the AppCenter –
You cannot record over a previously recorded clip. To replace the unwanted clip,
delete it and record a new one. Also, appending to previously recorded clips is not
supported; once the recording is stopped, you cannot start the recording again using
the same clip. If a clip is currently loaded when record is selected, the clip is ejected,
and a new clip is created before recording begins.
NOTE: Appending to previously recorded clips is supported through AMP Serial
Control Protocol. Contact Grass Valley for more information on control devices
available.
No pre-roll time — Recording begins as soon as record is selected.
About continuous record mode
Continuous record allows you to specify a fixed-length recording that records
continuously. When the fixed length you specify is reached, AppCenter begins to
erase the oldest media in 3 minute segments to make room for new media. In this way,
new media is continuously recorded while the recording is kept to a fixed length. (For
very long continuous records, the segment size groups up to 15 minutes.)
The continuous recording is stored as a program . The program thumbnail is displayed
in the Clips pane immediately after the recording starts. While recording, you can load
the continuous record program in another Recorder/Player application for playout or
