MX-4 contains features found on most video mixers. In addition, it contains the special features
described in this section.
Superb Video Quality — To ensure the highest video quality, the MX-4 uses 10-bit (4:2:2) video
technology for Y/C applications, and 8-bit 4:2:2 for composite applications.
Four Input Synchronized Switcher — MX-4 provides four input channels that mix analog
sources. This makes MX-4 useful in live production settings where up to four cameras or other
sources might be in use. MX-4 synchronizes the inputs, so picture disruptions do not occur when
switching between sources.
Picture-in-Picture (PIPs) — PIP allows mul-
tiple pictures to share the screen in various
configurations. For example, one source might
take the entire background while another
image appears inside a separate, smaller win-
dow, both sharing the screen at the same time.
You can use up to 4 images in a PIP configura-
tion.
Effects Generator — Use a variety of effects to enhance a source or transition between sources.
Select from over 700 effects, including natural shapes (diamonds, three leaf clover, and so forth),
fancy edges, and borders. You can also build your own custom menu for quick access to those
effects you use most often. Take advantage of FOCUS Enhancements downloadable subscription
site which provides additional new transitions and natural shapes to better serve your production
needs.
Time Base Corrector (TBC) — MX-4 automatically corrects the output’s time base. MX-4 stabi-
lizes the output signal even when the input sources are not stable.
Chromakey — Keying replaces
parts of one picture with another,
based on their color. Here the solid
background behind Kong is replaced
by the picture of the bridge. The
chromakey version shows Kong con-
templating the bridge.
Frame Synchronizer and Digital Video Mixer — Mix any two input sources together using a
variety of transitions — wipes, dissolves, flips, and so forth. With the frame synchronizer you can
mix independent video signals.
Compose — MX-4 provides a video painting
system you can use to combine video stills,
color shapes, and moving video on one screen.
You can create a screen that contains a video
still of a football coach (with a surrounding
red border), combined with a moving video of
the players in action on the field.
Audio Mixer — MX-4 provides sophisticated audio control. You can change the sound along with
the video, or play a constant sound while the video plays. Audio can come from a video source or
from external audio devices.
