So I have to organize a video presentation. There are different media. Photos, film, etc. The people on the screen may not see anything. Therefore, the question of a video mixer. But these are outrageously expensive, not for my wallet ... So I wanted to ask you whether it is not there a kind of fade. Say: mixer with only a one-and output, then the black will be blinded.

I had a similar thread. but something else: http://forum.slashcam.de/video-prasentationwieder-vt50044.html?highlight =

This is a simple request. Body on a screen and darkening the room, so that you no longer see; synonymous not on the canvas. * joke * ;-)

Yes, there is such a thing and if you have such a device can perform, it would be very convenient to have to be: So-called video processors. Since there is an image signal to black (or synonymous to a color) to hide. Many of these devices have built-synonymous Audio mixers and multiple video inputs (switchable image source).
At the analog days, I had a Vivanco VCR 3044 and later a VCR 4045th Both devices can, what you need, but it will be difficult, so one (working!) To obtain. Look at Google, what I mean. All images come from the same source: a collector from the Netherlands. In addition, these devices synonymous only video inputs, but do not have Y / C connections. : - /
On eBay there are currently several devices of this kind there, but computational times that a certain proportion of them simply do not work anymore.
What is still in question would be a genlock, which was originally used for an Amiga-picture into a video it. Even without the Amiga can be, for example, a 290 Hama Genlock to use a video screen and off. Here I would have perhaps even as a device.
Another approach would be electronic-design of the Neptune-or-Sirius Genlock. Even so you can video images and hide. Genlock advantage of that: In addition to video inputs are synonymous Y / C connections exist.

In most presentation programs, press the button "b" and it is a black picture on. Then you see nothing more.

s.einfachsten cheap and most is but a umschlter av-dzwischen to stop, then you can switch between different sources or black checkered stripes. übrigends costs only 10 ¬

Hello, there are several synonymous Beamer, a "Black" - have button. That would be synonymous simple Veriante.

ahh, thanks for the answers ... I will be the times with the Black-out button
