Chapter 6 Recording Clips
Before using Recorder
Select record channel video/timecode inputs – Before you start recording, you may 
need to check that you have the right record channel signal sources selected. 
“Selecting the video input type” on page 107
to select the record channel video
source.
“Changing the timecode source” on page 152
to select the record channel
timecode source.
Missing or intermittent timecode - If the selected timecode source is missing, i.e. 
LTC not connected, or VITC is not detected, the current timecode display shows 
XX:XX:XX:XX. Also, clips recorded without timecode will show no mark-in/
mark-out timecode after recording. When LTC is detected, but the signal is 
intermittent, the last valid timecode is displayed anytime the LTC signal disappears. 
Clips with missing or intermittent timecode will show this behavior during playback 
in a play channel. If external timecode is intermittent or missing, try one of the 
following solutions:
• Use the internal timecode generator as the timecode source for recording.
“Changing the timecode source” on page 152
.
• Stripe the timecode after the clip is recorded using the Player application.
“Striping timecode (replacing the timecode track)” on page 177
Re-recording and appending clips is not supported through the user interface – 
You cannot record over a previously recorded clip. To replace the unwanted clip, 
delete it and record a new one. Also, appending previously recorded clips is not 
supported, that is, 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 previously recorded clips is supported through serial control 
protocol using either AMP or VDCP Protocol Recorder applications. Contact 
Thomson Grass Valley for more information on control devices available.
