Fully upgradeable with optional DV Inputs, DV Output & SDI Output

The Datavideo SE-800 digital mixer allows you to switch between up to four analog or DV sources, and record the mixed output to a digital camera or recorder, or output a stable signal for live broadcast. The price and quality of construction of the SE-800 indicate that this product is targeted at corporations with video departments, educational institutions or public access stations who create live-switched programs on a regular basis. If you seek live-to-tape ( or air) switching of multi-camera studio applications such as news or a talk show, or live output to a big-screen TV at a nightclub or in an auditorium, the SE-800 will do the job.

The SE-800 can mix four separate audio and video channels, all synced by an internal TBC ( time base corrector) . Because you can connect almost any type of video, analog or digital, to any channel, the board gives you a huge range of flexibility in terms of sources.
We set up a simulated shoot in our studio with one camera trained on a host, and another on a talent against a green chromakey wall. Our third source came from a VHS deck, and our fourth from a DVD player.

The unit packs a number of transitions, including fades, wipes and zooms. You can use the T-bar fader, but in practice, the automatic Play button was more effective. The SE-800 has 30 user-programmable effects presets to store your transitions and execute them with a single button press.

The CHROMAKEY effect was easy enough to set. We trained one camera on our talent against a green chroma-wall and cued our deck to the sub-source. We pressed the Chromakey button and used the incremental level buttons to get a decent key, pushing the button to step through the various key settings ( there is also a color button for different colored keys) .
