Preparing a Video Project

For example, when the project frame rate is switched from 30 fps to 29.97 fps, the
start time is changed so that all the events currently in the project remain at the
same positions in relation to realtime. If you want the project start time to remain the
same, you must manually change it back after clicking the “Get From Video” button.
In this case, it is important that the video event is snapped to the timeline to ensure
proper positioning and synchronization within the project.
NOTE
• Cubase can only detect the supported frame rates (these are the frame rates
listed in the Frame Rate pop-up menu in the Project Setup dialog). Video files
with non-supported frame rates can be played back, but the time displays are
not correct in this case and proper positioning is not guaranteed.
Furthermore, audio and video may not be in sync. Therefore, we recommend
that you use an external application to convert the video file to a frame rate
supported by Cubase.
• If you have more than one video file in a project, it is advisable that all video
files have the same frame rate consistent with the project frame rate.
Nevertheless, you can work with multiple video files of differing frame rates,
but in this case you should always change the project frame rate to the frame
rate of the video file that you are editing at the moment. This is done in the
Project Setup dialog by selecting the correct frame rate from the Frame Rate
pop-up menu.
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
