The first thing you may want to do is enter a Base Name for captured files (this name increments numerically
when you start and stop recording).
ADD TO DDR
Figure 56
Enable the Add to DDR Playlist switch to automatically insert newly captured clips at the end of the DDR playlist.
These clips are available for immediate playback during your live production.
AUDIO HEADROOM
In digital audio systems, signal levels exceeding allowable values are clipped
(uniformly assigned the maximum value), inevitably entailing audible issues.
TriCaster's Record Configuration panel provides an Audio Headroom setting that
Figure 57
lets you choose an offset value (in decibels) between 0dB FS (the maximum allowable digital level) and the
benchmark 'alignment level'.
Hint: When playing files located in TriCaster's default 'capture folders', the DDR adjusts the audio level
automatically to produce an improved level match in playlists that include imported sounds or music.
SOURCE
A drop-down menu labeled Source permits you to choose which video stream to capture. TriCaster provides
two source options, PGM (Program output) and AUX (a particularly flexible option, since it can be set to a variety
of input sources and formats in Output Configuration). Note that direct input selections result in a recording that
respects the actual input format where possible, even if that differs from session format.
Hint: The FX Source option for Aux is particularly useful in connection with the use of a TimeWarp™ control
surface for instant replay applications.
ENCODING
The Encoding option menu allows you to choose between encoding formats for the recorded file. For many
purposes, the default Quicktime(R) 4:2:2 format is the best choice, and enjoys wide cross platform compatibility
with other software. Note that several options create a separate MP3 audio file in addition to the audio
embedded in the captured clip.
