UALITY

The MX-4 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.

 Q

UALITY

Images appearing on the MX-4 Preview screen do not represent the MX-4’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 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 
anytime using the 

DISPLAY

 

button. Refer to “Display” beginning on page 69 to learn about 

all of the display options.
