COMMON USES FOR MX-4
Multiple-Source Video Production — In a video production setup, you can connect one or more
video sources (VCRs, camcorders, video disc players, cameras, title generators, computer graphics
systems, and so forth) to MX-4’s four input channels. The Program output can then be sent to a
VCR or directly to a monitor.
You can determine what is sent to the output. While the original inputs play, you can switch
between any of the MX-4’s channels. Use dissolves or other transitions to go from one channel
to another. Add special effects to any channel, and use advanced features such as compose and
chromakey to enhance the production.
Single-Source Use — MX-4 supports A/A roll, a method for creating interesting transitions with a
single source. Its digital effects (such as picture freeze, posterization, and mosaic) give added life
to productions. You can use MX-4 with a titler to mix and superimpose titles. Time base correction
improves the picture (especially when making multiple-generation copies) by removing the jitter
common to most VCRs.
Live Video — In live production setups, MX-4 processes events as they occur. Good coverage
requires seeing the events from different vantage points—which means you need multiple input
sources. MX-4 gives you the ability to connect up to four sources simultaneously. For example, at
a sporting event, camera one might focus on the playing field, camera two on the team benches,
camera three on the announcer, and camera four on the scoreboard. Using MX-4 you can easily
switch between the sources whenever necessary.
NOTE
MX-4 is not an edit controller — that is, it does not control VCRs, camcorders, and similar devices.
You can control the sources manually, or use external edit controllers such as those manufactured
by FOCUS Enhancements.
