Building a broadcast-quality video studio for Skype in a 10×9 foot space

By | September 16, 2011, 5:00am PDT

Summary: One of the most exciting projects ZDNet columnist David Gewirtz has been working on is building a broadcast-quality video studio for Skype in a 10×9 foot space. Here’s the story behind that project.

This is the studio in webcast mode, where the egg-carton foam behind is used to enhance the sound recorded. There’s not much room for picture taking in this space, so this is taken from the door.

When the editors here at ZDNet and I put together our plan for DIY-IT, one of our key goals was to take you through some of the projects I’ve been working on. One of the most exciting has been a project I’ve been working on since about March, building a broadcast-quality video studio for Skype in a 10×9 foot space.

In this article, I’m going to outline the project’s basic goals and objectives, and in subsequent articles I’ll take you through many of the sub-projects that were necessary to put it all together.

Like most DIY-IT projects of mine, this is a work in progress. I’m adding, tweaking, changing, and improving as I go, and I’ll share that with you as well.

How it got started

I’ve been a renter all my life. However, as housing prices here in Central Florida became more and more affordable, my wife and I decided last February that the time had come to buy a house.

As I’ve discussed before, part of being a “professional expert” is the need to have multiple streams of professional income. To do that, and also to be a successful book author, you need to promote yourself and, essentially, turn your name into your brand. Over the past five years, I’ve done hundreds of radio interviews, many network TV interviews, and, now, for CBS Interactive, I do a lot of webcasts and lectures.

In the old rental house, I had my office in a loft that was over the living room and front entryway. That loft office was where I did my interviews and webcasts. It was adequate, but not great. If someone had to leave or enter the house, the front door was right below me (and it creaked). If I had to do a video interview (where I was the interviewee), light was almost impossible to control, and what you could see on camera behind me was less than fully professional. Sometimes you could see the hallway, sometimes my computer desk, sometimes I had a divider up to try to hide it all. It was tolerable, but far from great.

Even so, I preferred doing video interviews from home. Miami is a very long three-hour drive away, New York City is a very long three-hour flight away, and either of those choices would take me out of my productive writing loft for longer than I’d like.

Back to the house story.

When we decided to buy a home, my wife took on the task of hunting for houses during the work day, while I was working on projects with deadlines. Shortly after she started, she found the house we’d eventually buy. When she came home that day, after almost instantly knowing it was “the one,” she also told me it had a nice space for a studio.

I’d been unhappy with my office-as-studio space in our old, rented home, but I never really thought I’d have the option to carve out a dedicated studio space. But, as it turns out, the house we bought has a 125-inch by 95-inch room (that’s about 10 feet by about 9 feet) that is perfect for a studio.

I think it was probably initially intended as a baby’s room or a child’s bedroom, but since we don’t have kids, I immediately accepted the challenge of turning it into a studio for both broadcast-quality audio and video.

Disclosure

David Gewirtz

At various times during his adult life, David has voted for both Democrats and Republicans, and has been disappointed by both. He is deeply disturbed by how partisanship has come before patriotism in America, which gives him the freedom to pick on both sides.

David is a frequent guest on TV and radio stations across America and can usually be heard or seen on-the-air at least once a week. He writes weekly commentary and analysis for CNN’s Anderson Cooper 360 and has been interviewed by Fox News, CNN, various ABC and NBC affiliates, and Canada’s Global TV. He has been a featured guest on National Public Radio and has also been featured on Voice of America, Radio Free Europe, and Radio Liberty where his commentaries on technology, industry, and emerging nations have been broadcast into 46 countries (all in their own unique translations).

David is the executive director of U.S. Strategic Perspective Institute, a nonprofit research and policy organization. He is the Cyberterrorism Advisor for the International Association for Counterterrorism & Security Professionals, a columnist for The Journal of Counterterrorism and Homeland Security and a special contributor to Frontline Security Magazine. He is a member of the FBI’s InfraGard program, the security partnership between the FBI and industry. David is also a member of the U.S. Naval Institute and the National Defense Industrial Association, the leading defense industry association promoting national security.

David is an advisory board member for the Technical Communications and Management Certificate program at the University of California, Berkeley extension. He is also a member of the instructional faculty at the University of California, Berkeley extension.

David’s “day job” is as publisher and editor-in-chief of ZATZ publishing, an online publisher of technical magazines. Other than than his ownership stake in Component Enterprises, Inc. (the parent company of ZATZ), David has no additional industry investments.

ZATZ has many advertisers who do, in part, provide for David’s lush income and extravagant lifestyle. Most of them are IBM and Lotus aftermarket suppliers, some of them make goodies for Microsoft Outlook, and a few make all sorts of strange mobile devices and add-on products. David has been a regular judge of the IBM Awards, but has no formal financial interest in or with IBM.

Because the ZATZ online magazines often review products, David and ZATZ are sent an overwhelming stream of unsolicited, silly, and often useless products to review. Because they’re such a pain to track and ship back, these products often wind up in a dumpster or fill up the corner of a large closet. Although David has no plans to review products in connection to his ZDNet blog, if he does do a product review, he will disclose any relationship completely in that posting.

Both through ZATZ and independently, David derives a small income through various advertising and sales relationships with Amazon.com and Google. These are minor relationships and they will not impede his willingness or ability to chastise either company should they deserve it.

David has many other business relationships, but none of them relate to anything he covers in his ZDNet blog. David does have a bit of the sales-guy bug and if he’s not doing a sales deal with someone at least once a month, he goes through withdrawal. He has a number of consulting clients, but none of them relate to anything he covers for ZDNet (and if they ever do, he will either disclose that fact, or decline to write about them).

Back in the 1980s, David held the unusual title of “Godfather” at Apple. He has written and published 40 incredibly simplistic applications for Apple’s iPhone.

Although David is forbidden to disclose the terms of his iPhone developer agreement, he isn’t drinking the Apple Kool Aid, will never be confused with a metrosexual, and feels free to mock Apple, and Apple users, any time the occasion permits, on alternate Tuesdays, or if he’s bored.

Hi David,

Tools that might be interesting for your project:
- vidblaster --> production software www.vidblaster.com
- iris2iris --> teleprompter technology combined with webcams www.iris2iris.com

I think the latency will be your technical issue. The video stream is coming out off production software has a general latency of 2 to 3 seconds. This latency is too big to have a conversation within skype. It would be interesting to know if there is an skype add-on which give you your video production functionalities.

Sounds like a great project. It will be very interesting to hear your solutions. I hope that you will also include the tools that were -not- selected and why. Perhaps a 1-10 rating that would make it easy to tell if the less expensive item was -almost- as good as the selected item or if it was nowhere near the selected item.

Also, please clearly label each component as proprietary or open source.

As a follow-up article, how about writing on the most effective ways that mere mortals can improve their interactive presence. Perhaps some of that is simply based on how we use it (free). But, there are many who might be able to free up a USD 100 to 300 budget for something that would greatly improve their situation.

I don't work for them, but i got to be a beta tester.
It is a great solution for doing camera switching, lower 3rds and keying on a budget.
@DrVideo Boinx is a key part of the solution. I've got a whole article on that coming soon.
Where's some example video??

Looking forward to all of this - what you are doing is what any professional should think about if they perform any audio / video work or being interviewed in this manner.

Add a wall
BRD2 16th Sep
A small, square space with parallel walls will always produce poor audio (resonance, slap-echo, etc.). Consider adding a diagonal wall from about the middle of one wall to about the middle of its adjacent wall. You can use the space behind it for a helmholtz resonator or hidden storage area and use its front surface for your green screen). Break up the ceiling by hanging a couple of half cylinders and then carpet the floor. Make a recording before and after to impress your wife how cool it sounds even if it looks weird. Good luck and have fun.

Remote & Live
jim@... 16th Sep
We are working on a video project also, but instead of a studio, we are about Live Broadcast on location, via wireless, not Skype. Everything works well enough for our app, but the video source is the same problem. Unless you are ready to spend $1500-$3000 good luck. The C910 works for us but needs to be mounted on a hand held something for our app. Enjoyed you article
I work for a non-profit and needed to do about 20 four-minute videos that required a green screen. I ended with a sub-$100 Pinnacle Studio offer that included one, and the chroma key software and screen worked 100%. Since the screen was up and down (not permanent) a clothing steamer helped knock out the wrinkles.

two ideas for eliminating wrinkes
michaelis2928 21st Oct
@psion@... we built a frame from 1" pvc pipe 6 to 8" bigger than the cloth. folded the bottom over and sewed it creating a 6 inch pocket. filled a 3" pipe with concrete (or just use a steel pipe) slide that in the bottom socket to place tension on the screen. If you need more get little bunji chords and plastic spring clamps. You can get a bag full at Walmart for $8.oo bucks. Attach 4 or 5 of these on each side. You don't need a lot of tension. and the "profesional" ilet systems cost much more. My clamp system has the advantage of being moveable, and expandable. and you can build it today without waiting.

Somehow, I missed your previous article documenting the difficulty in finding a good Skype compatible video camera...

Years ago, I bought a new Sony camcorder with the justification it could double as a great webcam. It did - until Vista came along. Fortunately, I found an unsupported USB driver that got it functional again. But that only worked until Win7 came along. Fortunately, I found out I could add a firewire port to my desktop PC and get going again. But that only worked until there was a Skype update. Fortunately, I found out I could use ManyCAM software to recognize my Firewire input and feed that into Skype. But unfortunately, I no longer had 640x480 resolution. But then Skype ver 5 came out and I could no longer get a decent frame rate. So, what was once 640x480 30fps high guality video is now not much better than using a cheap webcam!

In summary, finding a solution today may not last long - at least that has been my experience over the last couple years.
to build high-end A/V so you can send 640x480 pixellated video over the internet.

I was able to eliminate studio Mics
michaelis2928 21st Oct
In a similar but larger (12 X 20 ) studio I had mixers, sound FX, and 5 condenser mics with phantom power, and a 18 megapixel camera etc. but when I bought the new Logitec 910c webcam with stereo mics the sound actually improved, doesn't sound hollow, and skype (Suposedly) only broadcasts in 720 mode (not 1080) which the cam will shoot video in at 10 megapixels. Around $60.oo bucks. comes with simple software for easy splicing. Jetman

We have eliminated Studio Mics
michaelis2928 21st Oct
Similar to studios above we do use foam "Walls" angled away from each other to discourage bounce. but our size is 12 X 20 ft studio with 5 condenser mics, mixer, FX, booms, etc. I got a sixty dollar Logitec 910c webcam (1080 & 10 megapixels) which gave us better sound than we had previously unless we used sm58s, with pop filters & held them in our hands. for bebinners the 910 comes with easy to use software for recording, but will only use 720 mode for Skype. It has good clarity & excellent sound without all the foam if you are within 4 feet of the stereo mics. Nothing like it in this price range, and the shortest learning curve I've ever had.
