Magic DaVE occupies 2 units in the rack which houses all the image processing, and has the inputs and output BNC sockets.  It also has four 'REF' (Black & Burst) BNC sockets, of which one is used for the 8x4 Video Switcher, and another is sent to Main Mux as a video input.

**''this is where the Magic happens)
* Compact Control panel (no direct access to keyers & Key bus) Software Version 3.0.


There is also a 'front end' on the director's desk which is used by the vision mixer during a show or OB.  This is the interface and is used to control the 2 unit device previously mentioned.


As you'll see from the Vision Path page, the four inputs to Magic DaVE are from DaVE P169 (whence 'DaVE' P169 gets its name).
==Connection==
* 4 inputs,  all analogue, each with the following options per input:
** Composite on BNC
** YPbPr on 3xBNC
** Y/C on Svid


The 'Program' row of buttons dictates what is its output.  The 'Preview' row is the input or picture which will be faded to next. 
* Key video input
** Composite on BNC
** For inputting a Matte


Fading is done by means of the T-bar.  The 'Program' out can be switched instantaneously (IE cutting to, without fading between inputs) by pressing one of the four input buttons, or Matte, Pattern, or Black.  Crucially there are a couple of buttons near the T-bar which dictate whether the T-bar fades, wipes, or cuts between 'Preview' and 'Program'.
* Preview output
** YPbPr / RGB on shared BNC's (3xBNC total)
** Settable via service menu


Usually Matte or Pattern should never be broadcasted.  Black will be used occasionally; EG at the end of a show, or during severe technical difficulties when a ticker bar should be overlaid from Graphics PC to explain the lack of transmission (grapics PC could alternatively give a slide to explain that there's a problem, this probably looks more professional).
* Program outputs
** YPbPr on BNC (2 of) (3xBNC per set)
** Composite on BNC (2 of)
** Y/C on Svid (2 of)


Magic DaVE has a lot of options and features.  It can do creative transitions between video inputs (some of which are a bit corny to say the least, but others such as 'wipe' which are good for variety). It can also apply visual effects to the output, such as solarise and probably a lot of others. Each of these features has a wealth of options to control the finer nuances, such as controlling the thickness and colour of the 'wipe' line between sources, or the threshold level of solarising.

DaVE is a Program/Preset mixer: this means, whatever is on the Program bus is ALWAYS what's going out. The Preset bus is what will go out if you fade across to it using the T-Bar. If you put one thing (call it 'A') on the program bus, and 'B' on the preset bus, and fade between them, at the end of the fade, DaVE will swap them over to make them the right way round again ('B' on the program, and 'A' on the preset). So, watch out! the T-Bar does not indicate which bus is live!
 
You can switch between items instantly, by just pressing a different source on the Program bus. DaVE can also do the transitions for you, use the 'take' button.

Using DaVE

DaVE is a Program/Preset mixer: this means, whatever is on the Program bus is ALWAYS what's going out. The Preset bus is what will go out if you fade across to it using the T-Bar. If you put one thing (call it 'A') on the program bus, and 'B' on the preset bus, and fade between them, at the end of the fade, DaVE will swap them over to make them the right way round again ('B' on the program, and 'A' on the preset). So, watch out! the T-Bar does not indicate which bus is live!

You can switch between items instantly, by just pressing a different source on the Program bus. DaVE can also do the transitions for you, use the 'take' button.

DaVE's panel allows you to change the transition type, (wipes, dissolves, pixelation, PiP...), the colour of the transition, it's size, position, angle, axis... DaVE also has a Huge pile of effects it can apply to the output - the list is almost endless, and again, you can change almost every aspect of them. Warning Attempting to master all of DaVE's quirks and abilities is impossible, don't try it! Also, most of the effects are incredibly cheesey.
