Edge Blending in ProPresenter 7
In ProPresenter 7, it’s easier than ever to set up and control Edge Blended projectors. To get started, go to Screens > Configure Screens. Here, you’ll see that our main output currently is set to a single screen, but let’s change this to Edge Blend. Now Edge Blending requires two or more projectors to make one large seamless projection image. Now you can change the number of devices that you want to Edge Blend here. And we can go up to five different screens to create one ultra wide projection image.
Now to select what projector you’re going to use, you need to select a screen and then choose which output device you want to use. You’ll see all of your currently connected system devices here, or you could choose from an NDI source, Syphon sources, or set up Placeholders if you’re working on this in advance, before you hook up to those projectors. I’m going to choose this screen as our first projector. Then I’m going to select this other screen and I’m going to choose this output as our second projector.
Now that we have our two outputs selected, we can start adjusting the blend area. So not only can you select your two screens, but you can select the center blend region. And this will show you our blend width, which we can increase or decrease. And you’ll notice that as we increase or decrease this, it changes the final output of our screen. So if you have a specified size, you want to hit, you can change your blend to be perfectly the size that you’re looking for.
And then you can go in and say, what mode is this blend area? Is it a linear fade between? Is it quadratic or cubic? And then you can change the radius and intensity to adjust what’s happening there. Also, you can go in and change color adjustments for the left and right screen when you have your center blend area selected.
Now let’s look at how to do this if you are using a DualHead2Go or TripleHead2Go device. Now to demonstrate this, let’s use a Placeholder and I’m going to make this 5760 by 1080 or a triple wide, 1080p screen. So now if we wanted to turn this into an Edge Blended screen, what we would need to do is go down to Edge Blend. And instead of using these full screens, what we’re going to is, we’re going to use different output targets of each one.
So instead of using the full output target here, I’m going to use a three to one grid. And then I’m going to change my devices to three. So now I have three different screens here. This is using the left third of that triple wide screen. I’m going to select my center one. Again, I’m going to choose my triple wide screen. I’m going to use a three by one grid. I’m going to say center. Then I’m going to select my last one. Again, triple wide output target three by one in the right side.
And now again, we can go in, we can adjust our blend area and we can make this a little smaller, maybe like all the other ones. And we can adjust the blend of this second area so we can make sure they match up and do any color adjustments that we want. But that’s how you would use a device like a DualHead2Go, or a TripleHead2Go to create an Edge Blended screen.
