For the fun of it I set up my camera to do some time lapse of us setting up our new projectors. I messed up the first part so i didn’t capture us getting the projectors up to the catwalk but what I did get is still kinda cool.
You can see that things don’t line up perfectly yet. I’ll get things pretty close with the projectors themselves then I’ll be relying on the Hippotizers for keystone, warping, and edge blending to perfect the image. At that point we should have a nice, seemless, 100′ x 18′ image!
Ok, it’s been an exciting week! After over a year of planning and demoing equipment we finally moved forward on our permanent install environmental projection system. It’s not set up quite yet but the gear is here!
The highlights of the system are the two Green Hippo Hippotizer HD media servers and four Panasonic PT-DZ21K 20,000 lumen projectors. This will be set up in our main Fort Lauderdale sanctuary. The final result will be a seemless image that’s 100′ wide and 18′ tall.
The goal is to finish the install this week. Once it’s installed I’ll post up some better pictures and videos of everything in action. We did get as far as racking up the gear and mounting the projectors temporarily on the catwalk. Ultimately the projectors will get mounted underneath our catwalk.
While testing the Hippos and getting them to talk to each other I played around with sending the outputs to Light Converse, my virtualization program. It’s pretty cool, the hippos can output a video feed over the network to LC. Then LC will show you the video on your video wall or projectors in the simulation. So not only can you preview all your lighting, you can preview video as well!
That’s it for now. If all goes well I’ll have some more pictures and videos of the setup soon!
We just finished another great Night of Worship. Over 3,000 people showed up to worship with us and it was awesome! We put together a projection setup like we have done in the past and overall things worked very well.
I don’t have any shots from the event, it was too busy, but here are a couple of pictures I took during setup and testing. Next time I’ll get some pictures during the event.
We just set up some projectors for our next Night of Worship. We rented three 12,000 lumen projectors and blended the image together resulting in about a 70′ wide by 18′ tall image. Everything is being fed from a MacBook Pro running ProVideoPlayer using a Triple Head 2 Go. We have 18 songs tonight, about 118 video cues in PVP. Lighting will be fairly simple since we’re not hazing the room but will compliment the videos.
Blending the three projectors is fairly straightforward. We’re not edge blending where the three projectors overlap a little. I’m using the existing architecture on our back wall to try and hide the seems. So where there’s already a break in the wall that’s where I have the projectors meet. Simple and works pretty well. One day when we have our permanent setup everything will be blended and keystone corrected to perfection, ha ha.
Since these are rented projectors I kinda have a checklist in my head for setting them up. Who knows how they were used last so I have to go through each one and make sure they’re set up right. I check for front projection mode so my image isn’t backwards. Then I check the image settings like color and brightness. With larger projectors they typically have multiple lamps and sometimes they’re not all on. Maybe the last event didn’t need 100% output or a lamp could be dead. I need everything I can get so I double check that. A good rental company will include a spare lamp or two just in case.
Color bars are a good way to test things. If the image is dark or the colors don’t match it’s easier to spot with color bars than your favorite motion background. PVP has a built in color bar slide that I’ll use to check color and brightness. Once I know that the three projectors match I’ll start to blend them together. I like to start with the middle and work my way out, then I know the image is centered and level.
PVP has a decent blend grid built in, that’s what I’ve been using. It has vertical center and horizontal center lines, I’ll square those up with the dead center of the stage first. Then I’ll use the center marks and grid to line up the other two projectors.
It really just takes trial and error and a little bit of time. Most larger projectors have lens shift options which is easier than physically moving the whole projector to line up the image. From there’s you just have to play with zoom and the legs of the projector to tilt the image if needed.
I’d say it takes about 15-30 minutes to get everything set up now that we know where to place the projectors and we rent the same ones each time. The very first time we did this setup it was probably closer to an hour of trail and error. Once you’re all set you should have an image that looks like one large projection to the audience.
Since we don’t always have this set up I played around with a program called Aeon during a soundcheck. It’s a pretty cool program that does live motion backgrounds that can react live to the music. The video isn’t great since we were on the catwalk but you get the idea. It looked pretty cool, definitely going to use this for a concert in the future.
We just finished up another Night of Worship at Calvary Fort Lauderdale. It was a great time of worship with a full sanctuary! As we have done the last couple of nights we incorporated environmental projection along with lighting to help create a worshipful mood.
Our sanctuary lighting consists of fixtures from Martin, Coemar, Wybron, and a standard collection of ETC Source 4 Pars and Ellipsoidals. Projectors for the back wall were 12,000 lumen Christies rented from a local company. We put together 3 projectors to create about a 75′ wide x 18′ tall image.
To control the video we used ProVideoPlayer triggered from Ableton Live so that the video clips were in time with the music. Some videos were triggered manually as well. Overall the night went well and all of the technology played nicely with each other.
