Settings for and management of video projectors 255
Output device: Use this option to specify which sound card plays the wave audio
objects. This is especially important if you have multiple sound cards installed on your
computer, e.g. "onboard sound" as well as an additional sound card.
Audio buffer: In order to allow smooth playback of a complex project, MAGIX Video
Pro X6 creates a RAM data buffer into which the current data is loaded. This allows
for step-by-step preprocessing instead of preprocessing for the entire project.
• Number of buffers: Here you can specify how many buffers should be used. More
buffers increase reliability and improve playback performance, but they also
increase the memory requirements. When playback goes through DirectSound,
only one buffer is used automatically.
Note: As a rule, if response and loading times are too slow, reduce the number and
size of the buffers. Otherwise, increase the buffer size if you are still having problems
with playback performance. Since error-free playback is usually more important than
fast reaction times, the buffer size should be raised to 16384 or 32768 to avoid
drop-outs. The possible number of used buffer updates is between 2 and 10.
• Multitrack size/Preview size: Specify the buffer size used to play the entire
project or for previewing waves in the file manager.
Video playback
Overload prevention for realtime playback: Here you can activate or deactivate
overload prevention during realtime playback of the project. This feature is
particularly suitable for lower performance PCs.
Instant cache refresh in Multicam Mode: Activate this mode to empty the cache in
short intervals which will make the preview for multicam editing immediately visible
in the preview monitor. This may result in juddering during playback.
Number of tracks for parallel track optimization: It makes sense to limit the number
of tracks when the program is running low on disk space and the project has multiple
videos in parallel.
Project window
Autoscroll during playback: If autoscroll is activated, the screen view automatically
shifts when the playback marker reaches the right edge of the screen, which is useful
for longer arrangements. You can select the size of the scrolling steps from either
"Fast" (whole pages) or "Slow" (half pages).
Attention: Scrolling requires constant recalculation of the screen view which may
lead to interrupted playback if system RAM is too low. If this happens, simply
deactivate the autoscroll feature.
