That is easy with vMix.

There are at least three ways (read more in help on Input settings/Multiview):

1. If you always want the Input (say a camera) with an overlay, click the input's setting (cog wheel) and then the tab "Multiview", and select your overlay Input as "1" (of the five available).

2. Another way is to click the Input's setting, and in the "General" tab click "Create virtua input". Next, for the new Virtual input do as above. Now you have the regular Input and that Input virtual with the overlay.


3. A third method is to add a new Colour Input (set to Transparent), and in its Multiview select your main Input (say a camera) as overlay Input 1, and your overlayy Input as "2". Now you have the regular Input and that Input with the overlay.

Good luck!

another way is to add a trigger from properties panel. Add a trigger to camera input or any input you wish. Set the trigger to act on transition in to overlay selected graphic and you can even set a delay so the overlay fades in a set time after transition

Using the right click previewing method, when transitioning from Preview to Output both the Preview and the Overlay layer will run their individual transitions, correct? By that I mean if the overlay effect was set to fade in across 500 ms, but the transition that was selected was a 750 ms wipe, both the fade and the wipe would execute when the transition button is clicked. This looks disjointed when the two images were supposed to come onscreen together. Richard's multiview/virtual input suggestions certainly work when you always want the overlay on with the camera, but with those approaches you wouldn't be able to transition the overlay off without transitioning the virtual input to the original camera input. I am going to make a thread in the Feature Request section about this, but I was wondering if there is a way to add a checkbox in the Overlay settings to use the preview layer transition and speed rather than the Effect's when the overlay is previewed.

@ Bardos

If still in Preview, just right click the overlay button again to turn it off.
If on Output or Program, the overlay is live and needs to be 'left' clicked to turn off.
If you only want that overlay for that input, I would suggest using the Multiview feature as suggested by Richard (I do this all the time for overlays such as a scoreboard).
Alternatively, you can set up triggers or shortcut keys to turn off the overlay when you change inputs, it all just depends on how much prep you are willing to do or if you just fly by the seat of your pants during a live broadcast.

Invariably, a downstream key (or overlay) is going to potentially be more troublesome in terms of showing up where you don't want it than an upstream key (overlay) that is pre-determined in your set-up.
I find it good practice to set-up an "emergency button" shortcut key that turns off all overlays (downstream) if I am dealing with too many inputs and am unable to navigate to the overlay input fast enough, it doesn't prevent the mistake, but it gets it off the screen faster.

(Note to Martin: not sure if it is a bug or by design, but when using the "fader" bar to transition in this scenario, the overlay does not transition with the Preview input)
