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 511.
3. From the pop-up menu in the Format column, select
an output format.
For the Onscreen Window output, only a “fixed” format is available. For
the other output devices, you can select different output formats for play
-
back depending on the device.
4. Adjust the Offset setting to compensate for process-
ing delays.
Due to delays while processing video, the video image may not match
with the audio in Cubase. By using the Offset parameter, you can com
-
pensate for this effect. The Offset value indicates how many milliseconds
the video will be delivered earlier in order to compensate for the process
-
ing time of the video material. Each hardware setup can have different
processing delays, so you must try out different values to determine
which value is appropriate.
Ö The Offset value can be set individually for each out-
put device. It is saved globally for each output device and
is independent of the project.
Ö The offset is only used during playback. It is defeated
in stop and scrub mode so that you always see the correct
video frame.
• If the quality of the video image is not a critical factor or
if you are experiencing performance problems, try lower
-
ing the value on the Video Quality pop-up menu.
Although higher quality settings make the video display sharper and
smoother, they also lead to an increased processor load.
Playing back video on the computer screen
The Video Player window is used for playing back video
on your computer screen.
• To open the Video Player window, pull down the De-
vices menu and select the “Video Player” option.
!
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.
