Live Edit Decision Lists
Edit Decision Lists are les used by non-linear editing
(NLE) suites to aid in post-production. Your switcher
can capture EDL data in a le that you load into your
NLE suite.
LiveEDL Setup
You can congure 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 > Config LivEDL.
2.
Use the GPO knob to select the GPI output that
is connected to your video server.
The GPI must be congured as a GPI output
before it can be selected.
3.
Use the Trigger 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 le 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 conrm that the switcher is receiving timecode data
from the switcher.
1.
Press MENU > STATUS > NEXT.
2.
Conrm 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 le. 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 le.
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 > Config LivEDL > 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:
