HILLSONG CHURCH TRIPLE SCREEN

[tnyturner]

Running three screens is pretty easy in the analog world. When you move into the digital world and want higher resolutions, it starts to get complicated. We ran ProPresenter with an Edirol V4 switcher. The other source was a video camera. We would keep the ProPresenter image on the center screen and fade the two outside screens between the Propresenter image and video camera depending on which part of the service we were doing. We could also switch the center image if needed. ProPresenter also allows you to run a separate stage display. We did this straight from the Mac using VGA. Pretty high tech on a low budget. We moved to a bigger facility and switched to digital for better resolution. We have had all sorts of problems with HDMI and will have to spend some money to duplicate what we were doing in the analog world. Also, ProPresenter's website has solutions to stretch the image across all three screens using a Matrox card. Hope this helps.

Thanks for the explaination; To do something like this, I'm thinking your going to need two computers, plus a matrix switcher, and a video switcher for your live video.

The layout is something like this. One computer with pro video play feeds into a Triplehead2go, which give you your ultra wide, across all screens playback.

Second computer, with dual head to go; one feed with lyrics and black background feeds into live switcher (or decklink card and alpha key module) then the second output is graphics, which feeds the middle screen via the matrix switcher.

Obviously live switcher is for switching your cameras, and overlaying your lyrics onto the outer screens. All inputs go to matrix switcher.

There could be an easier way to this; thatwas just my quick intial thought.

Hi, this photo caught my attention, Im just wondering what kind of screen did they used in this concert? a rear screen projector or a LCD ?

Those would be a very large direct view LCD displays, did you actually mean LED? I am pretty sure that is three rear projected images and it does not appear to be edge blended, just three separate images.

I think the general discussion has reflected three typical general scenarios:

1. A single image spanned across multiple screens.
2. Multiple screens with the ability to route sources to each individual screen.
3. A combination of the above.

Each of these may represent different potential solutions. Variables such as it being multiple distinct images versus one 'seamless' image, the ability to key graphics or text over the images, the types and resolutions of the input sources, etc. can also affect the potential solutions. That is why it is so important to identify fairly specifically what one is trying to achieve.

Yes, you can see that they used three bordered screens with the image stretched across them.

That is very simple to do.

You can also do edge blending if you have one projection surface. But it often isn't necessary if you line things up just right.

It becomes a little more complicated when you want different content possible in different parts of the screen.
