What is it?

A Panasonic MX50 Vision Mixer

What does it do?

A vision mixer or switcher merely allows you to switch between multiple cameras/VCRs at its basic level. The MX50 allows you to add extra effects when switching by add ing dissolves (cross fades) or spectacular wipes. You can also shrink pictures and 'fly' them around the screen or add SFX such as mosaic, negative or strobe effects. There is also a chroma-key function to superimpose a picture over a colour (usually blue or green) background, for example having your actors walking on the moon.

How do you use it?

Select your source from the source select buttons on the left, then use the T-bar to mix between bus A or B, (we have 2 cameras, a VCR and the G3 Mac).

The sliders on the far right select the audio source. We run the studio sound from the main sound desk into the MX50 via the AUX1 source.

The top half of the mixer contains the wipes and SFX functions.

Misc.

The MX50 is an £2,500 industrial vision mixer as it has XLR audio inputs for hooking up industrial VCR's. Panasonic also produce domestic mixers for around £800 which will work with domestic VCR's.

Broadcast vision mixers are huge, about twice the length of our sound desk! They can have around 10 or more source selects (we only have 4), some can have 30 !! They are incredibly expensive and produce much better pictures and FX than the industrial range.

NLE also has a 'virtual switcher' in its editing programs. Adobe Premiere has aroud 100 wipes and dissolves, and you can buy lots more as add-on packs. This is why NLE is so effective in the editing enviroment, however in a studio or live OB show it is not so good unless you record all the cameras seperately then edit them on a NLE suite.
