View Full Version : Split Screen - 4 Boxes - Help.

01-17-2012, 08:28 AM
Hi Everyone,

We have a Tricaster 450, running rev4 of the OS, and we want to split the screen into four independent wide-screen boxes (with no background layer). Each box would need to be selectable between a camera input or DDR. You would essentially be seeing a security camera type setup on screen.

Does anyone know if this is possible, and how to do it? Any help would be greatly appreciated!

Use the A over B preset (A, B and Overlay) in a virtual input plus one DSK for the fourth source.

Yep - or, depending on preference/need, two main DSK overlays + an 'A over B' LiveSet, or even a split screen using two VI's.

I use A/B with Overlay on Virtual Input and then add a DSK.
Here is a starting point for a four corner box effect using V1 @ A/B with DSK2;
Top Left Box: V1 Overlay = X -88.4, Y -50 and scale 49.5
Top Right Box: V1 A = X 88.4, Y -50 and scale 49.5
Bottom Left Box: V1 B = X -88.4, Y 50 and scale 49.5
Bottom Right Box: DSK2 = X 88.4, Y 50 and scale 49.5
This is for all 16:9 Session's with a small black cross in the middle.

This layout follows the 850CS so that it's easy to switch corners of the four box live (top of CS has Virtual Overlay, then A and then B. Utility is under that and left on DSK2). So this is how I get my box layout to be one, two, three and four counting top left to right and then bottom left to right.

Take care,

Thanks for the help everyone. Jose walked us through his method and we were up and running in no time at all. Works like a charm!

I have a Tricaster 860 and am trying to do a simple split screen. Just a two-camera split screen. It used to be the easiest thing in the world to do with old switchers, but I am going out of my mind trying to get the Tricaster to do it.

I looked at the "help" video from the John Lennon Tour Bus or whatever it is, and I tried to set my M/E bank up like his, but when I hit reset and crop, the positioner joystick has no effect on anything.

Can someone please help me?

Well, there are lots of ways to do this, but here's an easy one. Open an M/E, and assign the Transitions>Edge>Edge LtoR(H) effect to it. Select the desired two sources on the A and B, and pull the (M/E) T-Bar to taste. Voila....

I build all my box effects/split screens using VSE. it eliminates the errors or inconsistencies. then I build macros to load the box effect into each M/E.

Sure, and of course there are default double-box LiveSets.
