About Thumbnail Cache files
ÖTo display video thumbnails in the Project window, the 
option “Show Video Thumbnails” has to be activated in 
the Preferences dialog (Event Display–Video page).
When working with video in Nuendo, video files are dis-
played as events/clips on the video track with thumbnails 
representing the frames in the film. These are calculated in 
real time, i. e. they have to be redrawn during scrolling or 
moving. As this consumes quite a lot of processor power, 
reaction...

After the file is created, the window will be closed and the 
thumbnail cache file is used when necessary, i.e. under 
high load.
Adopting the Video Frame rate
When using video files within Nuendo, it is important to set 
the project’s frame rate to that of the imported video. This 
ensures that the time displayed in the SMPTE readout of 
Nuendo corresponds to the actual frames in the video.
1.Pull down the Project menu and select “Project Set-
up…” (or press [Shift]+S) to open the Project...

To view the video on the computer screen (as opposed to 
on an external monitor, see below), proceed as follows:
Under Mac OS, first make sure that “Onscreen Window” 
is selected in the Video Output section in the Device Setup 
dialog (Video Player page).
Pull down the Devices menu and select Video (or use a 
key command – by default [F8]).
A video window appears. In Stop mode, this displays the video frame at 
the project cursor position.
Playback of the video is performed together with all...

Playing back a video file using graphics cards (Windows 
only)
Multi-head graphics cards which support overlay function-
ality can be used to display the video picture on an exter-
nal TV or computer monitor in full screen mode. As of this 
writing, the manufacturers nVIDIA and Matrox have work-
ing solutions available. Check the card’s documentation 
for information on how it handles video output and how to 
set it up for multi-monitor display.

Adjusting the position of the audio event
1.If required, set the snap point in the audio event so that 
it identifies a significant point in the audio recording.
This would be the position in the audio that you want to match to a cer-
tain position in the video. If you don’t set the snap point, the start of the 
audio event will be used instead.
2.Activate Edit Mode on the Transport menu.
3.Select the audio event.
The project cursor position is automatically moved to the position of the 
snap...

Working with film transfers
Frame rates
Since Nuendo has been created from the ground up as a 
total media production system, it must be capable of work-
ing with all different types of video and film frame rates.
Standard frame rates
There are several frame rate standards in use today. They 
are as follows:
 23.98 frames per second (23.98 fps) used for cinema film to 
NTSC transfer.
 24 frames per second (24 fps) used for cinema film cameras.
 25 frames per second (25 fps) used for PAL/SECAM...

Film frames vs. video fields
One of the first things that needs to be understood is how 
video signals are formatted in general. Each frame or sin-
gle image of a video signal is composed of two video 
“fields”, each containing half of the image. The first field 
contains all the odd horizontal lines of resolution and the 
second field contains the even horizontal lines of the im-
age. This is called “interlacing” and is needed to minimize 
the flicker effect that would result if the image was...

4.The third film frame is transferred to the second field of 
video frame three and the first field of video frame four.
This is a block diagram of the 2-3 pull-down process. Notice that 4 
frames of film are transferred to 5 frames of video using the 2-3 field 
technique.
5.The remaining film frames are transferred in this man-
ner, alternating between 2 and 3 fields of video, until the 
end of the transfer.
After four frames of film have been transferred this way, an even five 
video frames...

Audio pull-down -0.1% (NTSC)
When working on a film project that has been transferred 
to NTSC video, most audio engineers prefer to use the 
original source tapes from the film shoot in order to retain 
the highest quality and fidelity. Audio that has been trans-
ferred to the videotape during the film transfer has suf-
fered a generation loss and speed change.
Since the video is running -0.1% slower than the original 
film, the audio must also be slowed down by the same 
amount as the film in...

Other pull-up/pull-down options
There may be other scenarios where non-standard pull-ups and pull-
downs can be used to correct mistakes. Nuendo provides further pull-
up/pull-down options for such situations in the Project Setup dialog and 
the respective section in the Project Synchronization dialog (see below).
Timeline adjustments when using pull-ups or pull-downs
When the audio clock of your audio card is being slowed 
down or sped up from an external clock source, Nuendo 
has no idea that...
