3. From the drop-down list, select the RT buffer frame size (stated as a
number of Megabytes). Choices are: 128 (default), 256, 384, 512.
Note EDIUS renders ahead using the Real-Time playback buffer from which frames
are then taken for playback. Memory reserved for the RT buffer is not avail-
able to other programs. If the RT buffer is too large, the system may run out
of physical memory which will degrade real-time playback performance.
Adjust the RT buffers with caution.
Note After changing the size of RT buffers, EDIUS must be restarted for the change
to take effect.
4. From the Sync Signal drop-down list, select the desired Sync Signal
type. The choices are "REF input sync", "Input sync" and "OFF(free
run)."
Note If the selected reference method does not supply the correct sync signal, it
will be automatically adjusted to a suitable method. For example, during play-
back, if there is no sync signal, the settings will change to "OFF(free run)."
During capture, it will be set to "Input Sync" automatically.
