There was a post over on the NewTek forums where someone was looking for a way to create basic layered sets, so I wanted to put a quick tutorial together here that explained how to leverage the power of TriCaster's M/E's to do exactly this.
NewTek's entire TriCaster line offers very powerful LiveSet functionality, allowing you to place chroma keyed talent into a variety of virtual environments. It mixes powerful video UV mapped video layers with z-layered still images to create a compelling live composite.
I've put together two basic sets that demonstrate this capability. The first set is a simple 'White Infinity' set designed to place talent in front of a white gradient background.
The second set I've put together is almost identical to the first set, but allows an image to be substituted on a background layer instead of having the fixed white background.
You can download a zip file of the two sets here:
How To Do This Without Custom Sets:
While these LiveSets are useful, they really aren't necessary for this type of composition. The Mix-Effect busses in today's Tricaster lineup have the ability to create this exact layout directly without the need for any custom LiveSet work.
To recreate this composition:
1- Load a keyable image in DDR 1 and a background image in GFX 1:
At this point, go to the keyable video you loaded in DDR 1 click on the gear control under it's video thumbnail (in the upper left side of the TriCaster UI), and use LiveMatte to key out the chroma background.
2- Select the M/E you want to use and set DDR 1 as the top layer 'A' source and GFX 1 as the background layer 'B' source:
3- Click on the Load Effect button for the M/E you will be using:
4- Select the Default tab under Livesets, select the 2 Layer set, and click OK:
Thats it! You will now see the 'A' Layer of the M/E keyed over the 'B' Layer, allowing you to set up any number of simple sets using any background image you want:
M/E's are an incredibly powerful tool for creating composites. When combined with the TriCaster's DSK's, you have an incredible range of layering tools at your disposal.
Hope this helps to jumpstart your use of M/E's!
