About recording clips
The Player/Recorder application records clips in AppCenter. You can play the clip while it is still
recording, or you can finish the recording, and then play the clip or add it to a playlist. In addition
to recording clips, you can add cue points to clips and create new sub 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 to create subclips. The media referenced
by the subclips that you create is saved outside the continuous record program and does not subtract
