Chapter 5
that if you select a screen mode that cannot be displayed by
the monitor you connected, this monitor will probably indicate
it does not find any signals. In that case, you will not be able
to confirm the screen and the system will switch back to the
previous monitor setting after 30 seconds in order to restore
your display.
A few limitations apply when running the system with a VGA
monitor, but these are not relevant to the final results of the
film. In the following we would like to give you a few tips on
how to work with VGA mode.
•SincethescreenrefreshrateofaVGAmonitorisnotthe
same as a television’s refresh rate (50 Hz), the video footage
will appear jerky when played, even though this has of course
no effect on the video output via the DV interface.
If your VGA monitor supports a frequency of 75 Hz, we recom-
mend you use a VGA resolution with a frequency of 75 Hz for
PAL in order to minimize picture jerkiness during playback. For
NTSC, we recommend you use the 60 Hz modes.
•Comparedtovideomode,VGAmodehandlescompletepic-
tures (non-interlaced). This results in a comb effect appearing
on moving objects (e.g. camera sweeps or cars driving by) so
that the edges no longer look sharp (fringed). This limitation is
of course only of relevance when displaying footage on a VGA
monitor and is not part of the actual video itself. To change
this, go to the “System settings“, press the “Screen“ button
and select the “Field“ option. This way, play-back is exempt
from artifacts.
•Thecolorsaturationandcontrastpropertiesofthepicture
displayed on a VGA monitor are very weak but they are dis-
played correctly in “Video” mode (television). Therefore, please
avoid increasing the saturation or contrast since this could
lead to color bleeding or distortion that is not visible on the
VGA monitor. Picture sharpness is also displayed differently in
VGA mode than it appears in the final video.
After you finish editing the video, we recommend you check
the saturation, contrast and picture sharpness of the footage
on a television in video mode.
•Theentirevideopictureincludingtheoverscanareais
displayed when working with various menus in VGA mode
(e.g. when playing, trimming or splitting a video). This area
sometimes contains image distortions that are no longer visible
when the video is later exported or viewed on the television.
When you are positioning titles, we recommend you do not
place them too far into the area around the edges of the pic-
ture or else the letters will no longer be visible later on. In any
case, please make sure you carry out a final check by watch-
ing the video footage on a television.
