MXProDV meets the highest video quality standards. However, video artifacts
can appear in video productions, especially when you use sophisticated effects
and transitions. This appendix describes some of the video artifacts that can
occur.
NOTE
The situations and artifacts discussed in this appendix normally apply to
advanced video concepts. They might, therefore, be of interest only to a
selected audience.

UALITY
Images appearing on the MXProDV Preview screen do not represent
MXProDV’s true quality because they serve only as a representation of the
images. Furthermore, the images do not show input effects or the results of
advanced setup options. Depending on the type of devices attached, you might
occasionally see lines along the sides of the preview images. This is especially
noticeable when using cue or review (search) with a VCR or camcorder attached
to an input jack, using poor quality video tapes, experiencing bad reception,
and so forth. In such cases, you might be able to improve video quality using
one or more of the following methods:
• Use only high-quality video sources.
• When using a camcorder or VCR with an Edit switch, turn the switch On to
disable playback processing circuits.
• Turn Off any sharpness controls and enhancement circuits.
Preview image quality does not affect video output quality.
You can switch to a full-size, full frame-rate version of the NEXT or CURRENT
source at any time using the
DISPLAY
button. See “Display” beginning on
page 87 to learn about all of the display options.
