Live Edit Decision Lists
Edit Decision Lists are files used by non-linear editing
(NLE) suites to aid in post-production. Your switcher
can capture EDL data in a file that you load into your
NLE suite.
LiveEDL Setup
You can configure your switcher to trigger multiple
GPI outputs at the start, end, or both, of an EDL data
capture to trigger video servers that are recording the
feeds coming into the switcher. The EDL data from
the switcher can then be paired with the feeds from
the video servers, using the timecode data, in the NLE
suite to edit or re-cut the show.
You can also set a pre-delay for each GPI output. EDL
data capture does not begin until the highest pre-delay
has passed. This is useful when the switcher needs
to wait for external equipment to become ready. The
example below shows the effects of various triggering
and pre-delay settings.
To Set the LiveEDL Behavior
1. Press MENU > System > NEXT > NEXT >
NEXT > LivEDL Config .
2.
Use the GPO knob to select the GPI output that is
connected to your video server.
The GPI must be configured as a GPI output
before it can be selected.
3. Use the Triggr knob to select when the GPI
output is triggered.
•
Off — GPI is not triggered
• Start
— GPI output is triggered at the
beginning of the EDL capture
• Stop — GPI output is triggered at the end of
the EDL capture
• Both — GPI output is triggered at the
beginning and end of the EDL capture
If Start or Both is selected, you must set the pre-
delay for the GPI.
4. Use the PreDly knob to select the pre-delay
interval (in frames) that the switcher waits after
the GPI output is triggered before starting to
capture EDL data.
Timecode Setup
The switcher uses timecode data to mark the EDL
file so that it can be used in the non-linear editing
suite along with the feeds from the video servers. The
timecode data can be either from an external timecode
generator, or internally generated. An offset can be
applied to both timecode sources.
For an external timecode, an LTC generator must be
connected to the LTC port on the back of the frame.
To Confirm External LTC Signal
If you have an external linear timecode generator
connected the
LTC
port on the back of the frame, you
can confirm that the switcher is receiving timecode
data from the switcher.
1. Press MENU > Status > NEXT .
2. Confirm that the timecode information shown
on the display matches the timecode from the
timecode generator.
If required, an offset can be applied to the incoming
timecode data.
To Set the LTC Timecode Source
If you are using an external timecode generator, an
offset, or delay, is applied to the incoming timecode
signal before it is stored in the LiveEDL data file. If
you are using an internal timecode, the offset is the
starting time that the switcher uses for the timecode
that is stored in the LiveEDL file.
Note: If a valid timecode signal is detected on the LTC port
on the frame, the external timecode will be used even if an
internal timecode is set.
1. Press MENU > System > NEXT > NEXT >
NEXT > LivEDL Config > NEXT .
2.
Use the Offset knob to select the source of the
timecode data you want to use.
•
Ext. — the timecode data received on the LTC
port is used
• Int. — an internal timecode is generated
3. Set the timecode offset for an External timecode as
follows:
a)
Use the
LTCOff
knob to select the offset, in
frames, that you want to delay the incoming
timecode signal by.
4. Set the starting time for an Internal timecode as
follows:
a) Use the Field knob to select the hours,
minutes, or seconds that you want to adjust.
The timecode is shown in the
[HH:MM:SS]
format.
b)
Use the
Value
knob to set the starting time in
the selected field.
