Settings for and management of video projectors 261

Preview size: You can determine the size of the buffer to be used to play the
entire arrangement or for previewing wave files in file managers.
Video playback
Overload optimization for realtme playback: Here, you can set whether
overload optimization should turn on during realtime playback. This function is
especially recommended for less powerful PCs.
Instant cache refresh in multicam mode: Activate this setting so that your
cache will be emptied in short increments, immediately visualizing preview of
multicam editing in the video monitor. This can result in jerks during playback.
Track count for parallel track optimization: Limiting the number of tracks
makes sense when the program has limited memory and the project contains
many videos.
Arranger
Autoscroll during playback: If autoscroll is activated, the screen view
automatically shifts when the playback cursor 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).
Warning: Due to recalculation, scrolling increases monitor visualization load,
which can interfere with playback depending on your system performance. If
this happens, simply deactivate the autoscroll feature.
Display (update in background): Object display updates following move and
zoom operations in the arranger take place in background to ensure smooth
work.
Spacebar properties: Here you can set whether after playback is stopped by
pressing the spacebar the cursor should go back to the original position or
remain at its current location.
Image material playback
Resizing high-quality image material: Use this feature to improve the quality
during resizing, particularly when downsizing to less than half of the original
size (e.g. for picture-in-picture effects). This, on the other hand, requires more
processing power.
Load image material in background: Images will be loaded in the background
to reduce CPU load.
