Rivendell uses a system of cue points within audio cuts, referred to as markers. Markers can be used to specify a number of parameters for a piece of audio. Consult Table 3.1, “Rivendell Marker Types” to see what markers are available, their purpose and their corresponding color.
Markers are set in the Edit Markers Dialog.
To access the Dialog, open an audio cart, select the cut to open
on the cut list and then touch the
Edit
button.
The Dialog is divided into three areas: the waveform area in the
upper half, consisting of the waveform display and
Amplitude
and
Time
buttons; the transport
controls area in the center, consisting
of Start
,
Pause
,
Stop
and
Loop
buttons along with an
audio meter;
and the marker button area in the lower third of the window,
consisting of controls for selecting and positioning markers.
The Edit Marker Dialog
It's possible to 'zoom-in' on the waveform in various ways by
clicking the Amplitude
and Time
buttons.
By default, the waveform
is displayed fully 'zoomed-out', thus showing the entire length of
the audio cut. The GoTo
buttons
can be used to jump directly to
the current play out cursor position, start or end of the waveform.
Audio can be played one of two ways: either by clicking on the
waveform to indicate where play out should start and then clicking
the left-hand Play
button,
causing play out to start from the
selected position, or by clicking the right-hand
Play
button, which
will cause play out to start from the Start Marker (just as it
would in RDAirPlay). Clicking the
Pause
button while playing will
cause audio to stop and the play out cursor (a thin vertical black
line in the waveform area) to freeze at its current position, while
pressing the Stop
button will stop
the audio while resetting the
play out cursor to the position it was in when
Play
was started.
Clicking the Loop
button will
cause the audio to play out
continuously, looping from end back to start, until either the
Stop
,
Pause
,
Save
or
Cancel
buttons are clicked.
To set a marker, click on the corresponding marker button and then
left-click on the waveform area to indicate where on the audio
the marker should be placed. (NOTE: With the exception of the
FadeUp and FadeDown markers, all markers in Rivendell are assigned
in pairs. For example, placing a TalkStart marker will also cause
a TalkEnd marker to be placed.) Markers that have already been
placed can be moved by selecting the appropriate marker button and
then dragging the marker to the desired location. It's also possible
to specify the position of a marker in the form of hh:mm:ss.s
(relative to time after the Start marker) by entering the desired
value next to a selected marker button. It is also possible to
remove a set of markers that have already been placed, either by
accessing the marker menu by doing a right-click on the waveform
display, or by touching the
Remove Marker
button and then touch
the marker button corresponding to the marker to be removed.
(NOTE: the exceptions to this are the Start / End markers, which
are always present and hence cannot be removed.)
Table 3.1. Rivendell Marker Types
Marker Type | Function | Color |
---|---|---|
Start / Stop | Indicates start and end points of audio. | RED |
TalkStart / Talk Stop | Indicates point to start and stop the Talk Counter in RDAirPlay. | BLUE |
SegueStart / SegueEnd | Indicates the start and end of the audio overlap during Segue transitions in RDAirPlay. | CYAN |
HookStart / HookEnd | Indicates "highlighted" audio, used by button panels and RDCartSlots when placed in Hook Mode. | VIOLET |
FadeUp | Indicates the point at which audio should be faded up to full level after starting in RDAirPlay. | YELLOW |
FadeDown | Indicates the point at which audio should start fading down to off before ending in RDAirPlay. | YELLOW |
As an aid for accurately setting the Start and End markers, it's
possible to use the Trim Start
and Trim End
buttons to automatically
set the markers to the first and last instances of the level
specified by the Threshold
field,
respectively.
It's possible to make copies of existing an audio cut on the system
by opening up the cut's parent cart in the Edit Cart Dialog,
selecting it on the cut list and clicking the
Copy
button. To
paste the copied audio, simply select the desired destination
cut (within the same cart or a different one) and press
Paste
.
