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 artefacts .
• 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 bleed 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 .
