window with several functions to be displayed:
• You can now specify the desired project you
would like to add. Clicking on the button Select
project causes project selection (similar to
Project settings) to be displayed, in which you
can select the desired film or project.
You can see that the active project is the same
one you were last working on.
It is not necessary to enter Project settings in
order to change the project. This can be done
from the DVD menu.
Note: Only those projects marked with a white
point contain video material.
• You also see the information Project length,
which indicates the length of the inserted
project.
• You can specify the Image quality of the project
after conversion to the DVD standard by clicking
on the selection control.
There are Four levels available:
Reduced, Normal, High and Maximum.
The image quality is determined by the data
rate (level of compression)- the better the image
quality, the more memory is needed.
High or maximum quality will fill up the DVD
more quickly then normal or low quality.
Reduced image quality guarantees that you can
write more than two hours of video material to
the DVD. Of course, this results in somewhat
lesser image quality. The program will warn you
of this with an appropriate message.
Normal quality corresponds to the quality
usually to be found on commercial DVDs.
High image quality corresponds to the demands
made by the DVD standard on playback devices.
This video should be able to be played back just
as normal quality is.
The Maximum quality level makes full use of
the DVD standard. Not all DVD players support
this quality level. This may be the reason if your
video should flicker or cause error messages.
Clicking on Ok displays an appropriate warning
message.
• The button Audio mode is used to specify the
audio quality: uncompressed or compressed.
Compressed audio requires only a fraction of
the capacity, but at the cost of slightly reduced
quality. When creating a music video, it is
recommended that you use uncompressed
audio.
Note for the technically interested:
Uncompressed audio uses PCM audio with 16
bits and 48 kHz. Compressed audio uses MPEG
audio.
• You are also shown the Size approximation for
this project. The calculation takes account of the
quality level (discussed above) and the duration
of the project. The value displayed is only an
approximation; the actual amount of required
memory, once created, may be slightly more or
less than this amount.
If not enough memory is present, then you must
either reduce image/audio quality or remove
other projects.
A message appears before a film is added if this
would cause the project to become too large to
fit on the DVD. In some cases the project could
still fit on the DVD, because the calculated value
