For those interested. This was asked for in the forums, so I thought I'd take a stab at sharing what I have done, but from scratch using mattes from google images.

I used these 3 sources...




I put these images in a folder, and imported this to vMix as a photos folder input and configured to loop and pushed play.

This gave me a test animated luma mask.

Next, I created an input for my background. In this case another photos folder with random birthday images.
Again, I looped this input and pressed play. This gives me an animated background.

Both of the previous inputs could be video sources if desired.

Finally, I created an input of my foreground video content.

In the settings of this input, I select the Color key tab, and then at the bottom, change the "Key/Fill Input" to the Luma Mask input.

The white from the luma mask allows the content to show, while the Black blocks the input.

Now, I can overlay this masked input over my background input, or select it as a multiview input for my background input.

Here is the result...


@sinc747, Tom, You should do this on Streaming Idiots!

I was playing with animated mattes to make custom wipe patterns and masks, it worked but was a bit of a setup.

Having them integrated as transition presets using user made animated masks as a source would make it a lot easier. Similar to a stinger in implementation.
A powerful feature the key / fill input in colour key.
