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 re-
drawing 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 automati-
cally 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.
Manually generating thumbnail cache files
If no thumbnail cache file could be generated during im-
port or if you have to “refresh” a thumbnail cache file of a
certain video file, because the file has been edited with an
external video editing application, you have the possibility
to generate the thumbnail cache file manually.
To create a thumbnail cache file manually, you have the
following possibilities:
• In the Pool, right-click on the video file that you want to
create a thumbnail cache file for and select the “Generate
Thumbnail Cache” option from the context menu.
A thumbnail cache file is created, or, in case there already existed a
thumbnail cache file for the video file, it is “refreshed”.
• In the Project window, open the context menu for the
video event, and select “Generate Thumbnail Cache” from
the Media submenu.
• Pull down the Media Menu and select “Generate Thumb-
nail Cache”.
Ö “Refreshing” an already existing thumbnail cache file
can be done only from within the Pool.
Ö The thumbnail cache file is generated in the back-
ground so that you can continue working with Cubase.
Playing back video
To check if your video equipment is capable of playing
back a video from within Cubase, open the Video Player
page in the Device Setup dialog. If your system does not
meet the minimum video requirements, a corresponding
message will be displayed.
Video is played back together with all other audio and
MIDI material, using the Transport controls.
Video settings in the Device Setup dialog
In the Device Setup dialog you determine which device is
used for playing back video files. You can switch between
different output devices during playback.
The Video Player page in the Device Setup dialog
To set up a video output device, proceed as follows:
1. Pull down the Devices Menu and select “Device
Setup…” to open the Device Setup dialog, and select the
Video Player page.
2. In the Active column, activate the checkbox for the de-
vice that you want to use for playing back video.
All devices in your system that are capable of playing back video are
listed. The Onscreen Window device serves for playing back the video
file on your computer monitor. For further information on output devices,
see the section
“Video output devices” on page 317.
!
For playing back video files, you must have QuickTime
7.1 or higher installed on your computer. There is a
freeware version and a “pro” version, which offers ad
-
ditional video conversion options. The player engine is
the same in both versions, so for mere playback in Cu
-
base there is no need to purchase the “pro” version.
!
You need a video card that supports OpenGL (ver-
sion 2.0 recommended) for proper video playback. A
card with OpenGL
1.2 can also be used, but might
put restrictions on the video functionality.
