Barco Event Master- Background as Canvas 5 Screens


(jazz music) – [Instructor] Hi it’s Tim Kuschel from The Evolve Academy. And in today’s example
we have five projectors that are being used as
a left and right screen and a three projector blend in the center with these resolutions. We’re also going to take
into account a 10 foot gap in between the screens
as part of our set up. Background content is
coming off a media server that’s generating three
3840 by 1080 outputs that’ll be butt-edged together
as a single background. On top of that canvas we’ll
be laying the five outputs from the U2 that make up
the screen configuration. I’ve gone ahead and done
some pixel math for you and given you the starting each positions for each of those five outputs along with the pixels for the gap. Using the event master
tool set and the simulator I’ve already pre-configured some items. I’ve set up three SDIs as
sources to look at for later. I’ve also set up three display ports as the background configuration
for our media server. Now, they’re a single
continuous background. I’ve told the system that
they’re 3840 by 1080p just so the system knows what
resolution we’re dealing with, and don’t forget you have
to disable three HDMIs or other connectors to give those connector capacities to the display port connectors. Next we’re going to
create the destination. I’m going to click on
the first HDMI connector and say Add Screen Destination. Then I’m going to click
and drag each of the HDMIs that make up this five
output configuration. You can do this with SDI as well as long as you have
enough SDI output cards. Then I’m going to select the destination and go to the adjust tab. Under the Wide tab is
where you’re going to configure the background as a canvas. Now you’ll notice there’s
a diagram of your outputs laid out horizontally. From the canvas drop-down select Use Background. And from the background drop-down we’re going to select Background1 which is our three display
ports from the media server. Then we’re going to hit
Apply as Canvas Size. Our outputs are left-justified according to the little diagram in the window so we’re going to hit
the center-justify button to center justify our
outputs on the canvas. This little diagram may
be a little hard to see. So to expand it to the main workspace you can use the Expand button to bring it out to your main area. With a couple clicks of Zoom you can see the entire canvas. Next we’re going to go into Expert Mode. This allows us to move
the outputs independently. Clicking on Output5
brings up a blue outline and now you can move that
output anywhere you want on the canvas or outside the canvas. Clicking on another output selects that as well and
adds to the selection. So be careful and remember
to unselect an output before moving on to one
of the other outputs. Now we’re going to select the first output and set its horizontal offset to 1140. Then we’re going to deselect
Output1 and select Output2 and set its H offset to 3600. Notice we now have our gap
in-between the first two screens. Then we will deselect
Output2 and select Output3. Its H offset will be 4800. Then deselecting three
and selecting Output4 we will set the offset for 6000. Notice that we have our overlap
sections for data doubling for our blended projectors. Now we select Output5 and we’re going to correct
our vertical offset from playing with it earlier to zero. And we’re going to set
the H offset to 8460. It’s in this expert mode
that you have the ability to either separate screens or overlap them on the same destination. Now for the most important step we’re going to click on the
disk icon in the lower left to save all of our work. Now we’re going to go
to the multi-viewer menu to look at what these outputs look like. We’re just going to look
at multi-viewer Output1. Going to screen Destination1 we’re going to drag the preview into the space. Notice the green vertical
lines show the output raster for each of the outputs. Next we’re going to drag the program just so we can see that as well. The multi-viewer is the most accurate way to see the outputs of your destination. It is very helpful when
you begin programming and placing layers. Now we’re going to go
to the programming page. You’ll notice that there’s
a gray bar that represents your active area, and it
may look a little bit off. This is normal when working
with a simulator in expert mode. If you have an active
multi-viewer hooked up you can actually see
the output that would be going to the projectors, and is very helpful when programming. Now we’re going to drop
some inputs into layers on the preview of this destination. Notice there’s no markings to know what screen we’re dropping them on or where they are in a relative
position on that screen. This is where it would be handy
to have a background still from the background server
that shows the screen locations as a reference when you’re programming. You could also use the multi-viewer output as your reference point. So if you go to the multi-viewer you can see that your layers are shown in the relative
position to the actual outputs. If you have an extended desktop set up this is where it’d be handy
to have the second desktop on the multi-viewer screen
while you’re programming. You can also set layers by the numbers. Selecting the layer and going
to the window adjustement menu which is the center of these three menus you can type in the window size 1920 to match the first output,
and then use your H positions based on your offsets. So our first offset for
that screen is 1140. So now, if we look at this
on the multi-viewer output we can see that it lines up
exactly with our first output. What would be handy right
now is to make a user key so that we can apply that
to any layer we want to put on the first screen. And we can go ahead and name
that user key Left Screen. Now we’re going to do
something very similar for the right screen. So selecting the right layer
and going to the adjust tab and then going to the window
adjustments for that layer we’re going to select the
size and make it 1920, we’re going to adjust the offsets vertical first to make it zero and then H offset for that
window is going to be 8460 to match our right screen. Again, if we look at it
on multi-viewer output we’ll see that it lines up perfectly with our right output, number five. And again, we’ll make a user key so that we can apply
that size and position to anything we want to
put on the right screen. So just to show you that
these user keys work we’re going to go ahead
and clear our right layer, select our left layer, and drag the Right Screen user key to it. That’s going to drop it in the position for the right screen. Likewise, we can drop
Left Screen on top of it and it puts it back on screen one. Be sure to hit save to
save all your hard work. One of the advantages
to this type of setup is to be able to take a single layer and stretch it across multiple screens. So here we’re rescaling
layer one and positioning it and if you look at the multi-viewer it is now stretched across
several of our screens. And that completes our first example of a background as a canvas. I’m Tim Kuschel with The Evolve Academy. Thank you for watching.
