Video files in the Project window
Video files are displayed as events/clips on a video track, with thumbnails
representing the frames in the film.
In the track list and in the Inspector, the following buttons are available:
Ö Some of these buttons may not be visible in the track list. In the Track Controls
Settings dialog you can determine which buttons are displayed in the track list, see
the section
“Customizing track controls” on page 702.
About thumbnails
The individual thumbnail images are positioned exactly at the beginning of the
corresponding frame. When you zoom in and there is enough space between the
frames, the thumbnail is repeated as many times as there is free space available. Thus,
you can always see a thumbnail regardless of how much you zoom in.
Thumbnail Memory Cache Size
In the Preferences dialog on the Video page, you can enter a value for the “Thumbnail
Memory Cache Size”. This determines how much memory is available for displaying
“real” thumbnails. The currently shown image is buffered in the thumbnail memory
cache. Whenever you move to another image and there is no memory capacity left,
the “oldest” picture in the cache is replaced by the current one. If you have long video
clips and/or work with a large zoom factor, you may have to raise the “Thumbnail
Memory Cache Size” value.
About thumbnail cache files
When importing video, Cubase automatically creates a thumbnail cache file. The
cache file is used in situations where the processor load is very high and the correct
redrawing or realtime calculation of thumbnails might use system resources necessary
for editing or processing. When you zoom in on the thumbnails, you see that they are
in a lower resolution, i.
e. the pictures are not as clear as when they are calculated.
When the processes that rely heavily on the computer CPU are finished, the frames
are automatically recalculated, i.
e. the program automatically switches between
realtime calculation of the pictures and using the cache file.
Ö There are situations where no thumbnail cache file can be generated, e. g. if you
import a video file from a folder that is write-protected. If you have access to the host
folder at a later stage, you can generate a thumbnail cache file manually.
