being ready to start recording, this corresponds to the Triggered or Timecode
mode. A 'red dot' indicates a recording in progress.
7.4.1 Mode
The triggering modes define how the recorder is initiated. There are three
different modes.
The most simple mode is Manual. In this mode the user has to manu-
ally press the 'Record' button to start and press the 'Stop' button to end
the recording. Although simple to operate, this mode does not give accu-
rate control over the timing of the begin and end of the recording. Both
human interaction and operation through a web-based user-interface will
introduce some degree of lag.
An automated way of starting and stopping the recording process is done
in the Triggered mode. One of the data channels is allocated to control
the start/stop. The channel address is denoted by the 'Trigger Channel'
field. It is advised to include this channel in the show programming done
on the external source; a typical lighting console allows accurate timing
of DMX channels which gives fine control over when the recording starts
and ends in relationship to the show content. When using the Triggered
mode pressing the 'Record' button will prepare the track for recording;
it will be erased when necessary and then stay idle in anticipation of the
trigger channel going high to indicate 'start'. The recording is ended by
setting the trigger channel to 0%.
The Timecode mode allows for the recording process to be synchronised
by incoming timecode. Pressing the 'Record' button will prepare the track
for recording; it will be erased when necessary and then stay idle in antici-
pation of the timecode to start running, it stops when the timecode resets
back to 00:00:00.00. Always record from frame 00:00:00.00. If the content
is supposed to run at a different frame then use the playback's 'TC Offset'
property to achieve that.
A typical challenge with recording dynamic DMX data is to create a seamless
loop. Often the manual mode will most likely not be sufficiently accurate to
achieve a seamless loop. The triggered mode offers a way to remote control
and make the recording seamless. Alternatively, the lighting content can be de-
signed in CueluxPro instead of recording from an external source, as CueluxPro
automatically takes care of making its content seamless.
