Chapter 4 Recording clips
About recording clips
The Recorder (HD-00 and SDA-00 K2 Media Client) or Player/Recorder (SD-00 K2
Media Client) application requires a record or 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 VITC or LTC timecode - If VITC or LTC is the selected
timecode source and the signal is missing, i.e. VITC or LTC not connected, 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 VITC or
LTC is detected, but the signal is intermittent, the last valid timecode is displayed
anytime 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 or
missing, 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 Player application.
Using the video input noise reduction filter – The video input noise reduction filter
provides pre-filtering to enhance the picture quality.
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, 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 to previously recorded clips is supported through AMP Serial
Control Protocol. Contact Thomson 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, K2 Media Client 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 a 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 from the continuous record length.
The subclips can be inserted in a Playlist application as play events.
Note: a program, such as a playlist, cannot be saved in AVI format.
