In order to maximize space for this business one of the things we could do was lean to a professional studio design and create a lighting grid. A lighting grid is a system of suspended steel pipes in a crisscross design for hanging lights and other devices from the ceiling. A typical grid has pipes spaced with 4ft gaps proving lots of spaces for mounting anything you would need in a studio. Before trying to rig up a grid in your space make sure to first consult a professional as these need to be set up safely and up to building code. A typical grid for a small space can weigh as much as 800lbs and needs to be anchored correctly to be able to handle even more load than you plan to attach. For this grid, we used special concrete anchors to hold one direction of the grid and another custom grid clamp to join everything together from our favorite people at The Light Source.

Green screens can offer a lot of versatility and open new doors of opportunity to create more content in your studio or gain more experience with your production skills. So, let’s take a look at some of the challenges and benefits of working with a green screen in your space! We recently were able to install a green screen for a corporate studio. Their needs presented a unique set of challenges and benefits to having a green screen in their studio. So, let’s set the stage: The corporation had set aside a space for a video studio and had the goal to create quality video content to present to the rest of their organization and their network. What they didn’t have was a very large space and being a corporation, they also knew they needed to be able to produce content quickly for more immediate use. Knowing this, using a green screen sounded like a desirable way to get what they needed out of their studio!
Understanding the end goal and use case for any system is crucial to its design and success. Starting with a clear vision allows for figuring out what pathway and components are needed to create a solution that meets the end goal.

Going from a room that has little, to no video tech infrastructure can often seem like a daunting and expensive task. Thankfully as the need has grown for video systems, there have also been new products released to make it much easier for anyone to step into a full video setup without biting the bullet on budget. The Springs Church, here in Colorado, decided it was time to add a compact streaming setup to a room that was previously offline. They were looking for just such a system; one that would not break the bank or be overwhelming to learn. This new video install not only allowed them to livestream and capture footage from this room but provided more flexibility during events.
The last form of Keying we wanted to highlight is Linear or alpha keying. Linear or Alpha keying is the evolution of the Luminance key and Pattern keying (read HERE). Linear keying becomes a basis for where we can build almost all advanced keying. It typically requires special hardware and software but gets you great results. Linear keying is made from two separate signals. The first signal is called the Cut Signal. The Cut Signal is a luma-based signal of white, black, and grayscale that tells the switcher what is opaque (black) and where to put a GFX signal (white). The second signal is the Fill Signal or the actual GFX or colors. (Pictured above) The switcher uses the Cut Signal as the pattern shape, which allows the benefits of a luma key while eliminating the con of not being able to have things like a black outline. This is because the switcher is using one signal to say where things are opaque and another for what the actual content will be.
Introducing a new favorite on the market: The Blackmagic ATEM Mini Extreme ISO! This a low-cost, multi-camera, live production with advanced broadcast features, compact switcher. ATEM Mini switchers (Atem Mini and ATEM Extreme pictured above) make it easy to create a professional multi camera production for live stream, business presentations, or podcasts. You might already know that the ATEM Mini models have a USB so you can use any streaming software, but the ATEM Mini Extreme also adds live streaming and recording to USB disks. It also has an additional 8 HDMI inputs, 2 separate HDMI outputs and a Multiview with up to 16 views.
Luminance and Pattern KeysKeying is a powerful and essential feature on your video switchers. It's important to know the basics behind keying so you can really understand what is happening on your switcher when you use these features. We've talked about Chroma Keys, HERE, so now we want to highlight another similar switcher key: Luminance Keys.
Running from the Constellation we have 2 eight lane fibers, one going to the Broadcast room and one to the video studio. With fiber, there is no need to worry about any issues with the length of your run, as you might have to think about with SDI and HDMI. Fiber is also able to support 4k 60/12G making it a great option for making sure your system is future proof. These lines are run through Blackmagic fiber converters to convert the signal to SDI, giving four inputs and four outputs to and from the switcher in both the broadcast room and studio. One of the greatest features of the Constellation is that all the outputs on the switcher are fully routable Auxs’. That means that outputs from the switcher to the broadcast room and the studio can be used to send multi-view, program, graphics inputs, camera control, or any other content that needs to be fed to the switcher. MSC already had 4 BMD Broadcast cameras so with 4 inputs in the studio all of them can be utilized at the same time if the situation calls for it. With the studio, we also built out an entirely separate audio system that also had some integration into the sanctuary. In an effort to make onboarding and training new volunteers simple, MSC had already made the decision that they were going to have all of their audio systems, other than the main auditorium, be by Allen & Heath. In the broadcast suite, we put an A&H SQ5 and paired it with an A&H AR2412 digital stage box in the video studio. This gives them very flexible I/O and even the ability to do a full band in the studio space if necessary. Also, in the studio are 4 Shure BLX mics, both lavalier, and handheld. For the last piece, for monitoring in the broadcast suite, we put a pair of Presonus E44 studio monitors at the audio desk and a pair of Presonus Eris E3.5 for the video desk. Between the first install at MSC and the studio build, MSC has a lot more room and capability to create more professional video content for their growing online needs! Not only does their new set up help them successfully produce content now, but offers further options for them to continue to expand in the future.
