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 DV’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 MX-4 DV’s channels. Use dissolves or other transitions to go from one chan-
nel 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 DV 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 DV 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 DV processes events as they occur. Good coverage
requires seeing the events from different vantage points—which means you need multiple input
sources. MX-4 DV gives you the ability to connect up to four sources simultaneously. For exam-
ple, 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 DV you
can easily switch between the sources whenever necessary.
NOTE
MX-4 DV 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.
