The MX-4 DV 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.

UALITY
Images appearing on the MX-4 DV Preview screen do not represent the MX-4 DV’s true
quality because they serve only as a representation of the images. 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 fol-
lowing 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
anytime using the
DISPLAY button. Refer to “Display” beginning on page 69 to learn about
all of the display options.
