Robust Portable Live Streaming on a Budget

In 2019, I built a new live streaming PC for Awakening Church. I am excited to share the details of our live studio PC and how you can build your own to have high-quality live production switching and streaming without the typical high cost.

A few months ago we shifted to recording our weekly broadcast in advance using DSLRs, but we’ll soon be returning to a live workflow and we will be using this equipment at the core.


Back in 2016, Awakening Church used a single Blackmagic Pocket Cinema Camera with a Teradek VidiU to stream to our own self-hosted live video server. Times have changed. We now have a multi-camera production with live switching to make it easier to produce live streams.

Before our latest 2019 build, we used a custom computer built in 2017. This computer worked well but each camera required a lot of cables: power, SDI, and VISCA in/out. This made cabling heavy and cumbersome to setup. Additionally, the PC was in a standard case, which means we had to setup all cabling from scratch every week.

This computer was stolen in late 2019. We thankfully had insurance which covered the cost of building a replacement.

Awakening has been and still is a mobile church which needs to setup and teardown every week. When building the replacement, we kept setup and teardown issues in mind.


  • Entire system easy to assemble and store
  • Operation by a single volunteer — this means remotely controlled cameras
  • Save money over commercial systems costing $8K+
  • Reduce cable needs

Our 2019 build

We used Vimeo Premium and its bundled Livestream Studio switcher for video production, so the entire computer is built to run this program.

The software requires hardware acceleration for best performance, so we chose a processor with an integrated GPU which supports Intel Quick Sync video to offload some H.264 encoding and decoding tasks.

We adopted NDI|HX cameras which can handle power, network control, and H.264 video all in a single Ethernet cable.

We no longer need a capture card for every camera, but we still need one for capturing ProPresenter slides.

We use a rackmount design to allow the computer to remain in a portable rack alongside a PoE switch and PDU. This lets us easily setup and teardown the system every week.

Here’s a picture of the portable PC rack:

Live PC in Gator Rack

The EdgeSwitch is for the camera network. The switch provides power to the cameras and a PTZ controller which makes it easy to move the cameras. You could also just use the PTZ controls within Livestream Studio to save more on costs.

Here’s the part list, including the switch, PDU, and Gator rack:

We already had a donated 150W EdgeSwitch, so the cost isn’t included in the above list.

Here’s the interior:

Recent additions in the above photo not included in the part list are an internal hardware license USB dongle and onboard Wi-Fi. And yes, that’s a Fry’s receipt for Rip-Ties. So long, Fry’s.


In March 2020 we setup this equipment semi-permanently in our church’s studio. Here’s a photo of the early setup. We now have large 4K monitors instead of a single small one, but this small monitor worked well for easy storage in a Pelican 1650 case.

Hasty setup in the early quarantimes


This system performs well for a fraction of the cost of typical commercial live streaming systems. The Intel i7-9700 includes an integrated GPU with Intel Quick Sync video which hardware accelerates H.264 encoding and decoding in Livestream Studio.

However, this setup did not perform well when adding a third camera.

After adding a third NDI|HX camera, we’re starting to hit the limits of performance of this system when also used with a computer HDMI input which requires conversion.

My friend Douglas suspected thermal issues with the CPU, so we looked into that as well, but the real issue appeared to be the need for a dedicated GPU to keep the CPU workload down.

Adding a GPU

We added a Quadro P1000 graphics card from B&H after running into performance issues. Livestream Studio appears to work much better with this card in place. Our previous CPU usage was very high — often over 85% during recording and streaming. We’re now back down to about 50% according to the operator who ran cameras today.

This added $317.99 to the cost of the above build.

Quadro P1000 graphics card installed inside a rackmount PC

I’d bet you could save some money and get a Quadro P400 to do the same job. It’s the same card used in Livestream’s own high-end HD51 4K edition which costs $8,999. (See Livestream product datasheet.) The P400 card is only $118.74 from B&H.

The integrated GPU is disabled in firmware by default because we added a dedicated GPU. I was curious if running both the iGPU and Quadro would be beneficial, but I didn’t bother turning it back on after the tests went well.

If your build is not constrained to low-profile cards due to a 2U rackmount design, you have a lot more options for hardware encoding and decoding with NVIDIA than the Quadro series, but this card does quite well and includes a regular-sized bracket for use in traditional PC cases. Since the P400 contains the same hardware H.264 decoding and encoding engines and stream limits as the P1000, consider the P400 before needing to add on more cost with a more expensive card.


The rackmount setup in a portable case is ideal for setup and teardown. Using NDI|HX takes more compute resources but really reduces the amount of cabling. And the machine is very easy to build with commonly available parts.

We are preparing to use this equipment again for live streaming in an outdoor setting under a tent. In the future, I look forward to sharing what we learn from adapting this equipment to our new environment.

Waters from the Wilderness

Today I took a trip to the Pulgas Water Temple. It’s only open on weekdays, so I stopped by for a few minutes late in the day. I took these pictures on my Canon EOS 6D with my go-to 17-40 f/4 L lens.

This stone structure near Interstate 280 commemorates the completion of the Hetch Hetchy Water Project.

Water from the Sierra Nevada mountains can be heard rushing past a waterfall in the center of the temple. A reflection pool in front of the temple makes this a beautiful place to visit.

Inscribed on the frieze and above the waterfall is a wonderful reminder of God’s provision:

I give waters in the wilderness, and rivers in the desert, to give drink to my people. Isaiah XLIII:XX.

Building a Live Video Broadcast Switcher PC

I originally wrote this post in late 2017. A lot has changed since then! Our original PC was stolen from a storage facility and we rebuilt it. I’ll be sharing our 2019 rebuild in an upcoming post.

In 2017, I helped build a Windows PC to run Livestream Studio for my church.

Livestream Studio is a proprietary live production video switcher which can accept multiple video inputs and screen capture video from a Mac over the network. An update earlier this year allows for hardware accelerated H.264 encoding which makes this system usable on cheaper processors.

Why Studio?

Studio’s new hardware acceleration means we can do multiple HD feeds on relatively cheap processors. Studio works well with a customized keyboard which is very nice. There are many competitors in this space, I believe you get what you pay for here.


This is an unusual system with many requirements unique to our application:

  1. The system must run Windows because Studio requires it.
  2. The system must be powerful enough to run the CPU intensive Studio program with multiple video feeds.
  3. The system requires two PCIe x4 slots with at least one more for expansion to run HD-SDI video capture cards.
  4. The system requires a secondary NIC to receive video and audio from a separate laptop running ProPresenter.
  5. The system should be affordable with a budget of $1,800 excluding the cost of Studio.
  6. The system must be portable and fit into one or more Pelican 1650 cases. Our church needs to tear down all equipment every week.
  7. The system must be quiet: it’s going to be used next to the seating area of the auditorium.
  8. The system must support USB 3.1 Gen 2 for a very specific external drive requirement.
  9. Ideally the Livestream USB hardware dongle would fit inside our computer’s case to avoid losing or damaging it.

We’ll accomplish this build with the help of PCPartPicker which handles all of the compatibility issues between parts. I’m not going to consider parts which are not on this resource — the power of the tool for checking for compatibility issues is too valuable, especially with limited time.

Off the shelf: Livestream HD switchers

Livestream produces HD switcher PCs as a turnkey system. However, the PCs they produce are way out of our budget. They use Intel Core i7 processors of various generations.

Off the shelf: Intel Skull Canyon NUC

The Skull Canyon NUC is used in Livestream’s All-in-One Kit and PTZOptics’ Producer Kits. It’s a good system with a Intel Core i7 6670HQ @ 2.60GHz producing a score of 9,682.

I was about to purchase this system along with some used Blackmagic UltraStudio SDI external capture cards; however, I changed my mind due to a few troubling factors:

  1. Livestream’s All-in-One guide really pushes this system to its limit and it’s accepting 3 HD streams as configured with typical CPU load of 60%. This is okay but it means the system will run hot.
  2. This system has a loud whiny fan at 59 dB. This is a deal breaker for a quiet space.
  3. The nice UltraStudio SDI devices are discontinued. Magewell produces a similar device for SDI capture, but reviews state the SDI port is difficult to use being recessed into the case. This is not good for repeated abuse when setting up and tearing down 50 times a year.

Going full custom

Nothing off the shelf works. Let’s do this.

Custom parts

Form factor and case

We’re looking for something like a Micro ATX form factor. The Cooler Master Silencio 352 was selected for its sound dampening material, low cost, clean interior, and dimensions that tuck nicely into a Pelican 1650. Full ATX would be too large to be portable, so this removes a lot of motherboard options.

Hardware encoding

The system requirements for hardware encoding states we need a Intel Quick Sync CPU or a NVidia NVENC graphics card to offload H.264 processing. Quick Sync appears to give better quality in a benchmark test.

Quick Sync is present in recent Core i7 and Xeon E3 processors with integrated graphics.

ECC or not

Ah, to ECC or not to ECC. This is supposed to be a reliable system — a crash would cause an outage of our live video. So, I explored using ECC RAM.

ECC RAM means you must skip to Xeon processors. If we want to use Quick Sync, this leads us to a Xeon E3 line of processor. The fastest E3 according to is the Intel Xeon E3-1275 v6 @ 3.80GHz, which is a modern Kaby Lake processor with a score of 11,445.

In comparison, the Kaby Lake enthusiast Intel Core i7-7700K @ 4.20GHz gets a score of 12,174.

The trouble comes in finding a good motherboard. The Asus – X99-M WS Micro ATX LGA2011-3 Motherboard is one of the only Micro ATX boards available for this processor. While it includes attractive features, it does not support video connectors to take advantage of the embedded GPU for displaying video. We’d need a cheap graphics card which will consume a PCIe x16 slot. There are 4 slots, leaving us with two open PCIe x16 slots and a PCIe x1 slot. This is just enough.

In this setup, the additional cost doesn’t come from ECC RAM: it’s the graphics card and relatively more expensive motherboard. While the X99-M is one of the most reliable motherboards it’s extra cost will put a strain on meeting the budget and a plain i7 7700K gets a better CPU benchmark score.

In the meantime, Livestream themselves are shipping $10K systems with Core i7s and no ECC RAM.

Let’s forgo ECC in favor of a Core i7, which is used in Livestream’s official products.


We’d like to expand with a few extra PCIe x4 slots available. A few options work here. We picked the Gigabyte – GA-Z270MX-Gaming 5 Micro ATX LGA1151 Motherboard because of the open slots — it’s one of only a few boards that had room for expansion in this form factor. Despite the gaming styling, the brand is noted for reliability over competing Micro ATX offerings by other brands.


The Intel – Core i7-7700K 4.2GHz Quad-Core Processor hits the sweet spot of price and performance with a score of 12,174. This is a bit better than a similar Xeon and significantly better than the Skull Canyon NUC.

The CPU is cooled with a Cooler Master – MasterLiquid 240 66.7 CFM Liquid CPU Cooler to allow for easy access around the CPU and for clean appearance in the case.


An inexpensive IPS 1080p monitor was chosen to do the job. The monitor and its stand are thin enough to fit in the top foam of a Pelican 1650 and it’s very easy to tear down the monitor stand into flat pieces — a must for packing this system into a case.

Everything else

32 GB of memory, a 480GB SSD drive, and a reliable EVGA power supply round out the build.

The parts arrived a few days after ordering.

A team of people from my church helped assemble the PC.

Various internal components of the PC

This was our first time assembling a computer, so we took our time. But it was all fairly simple.

Assembling the PC case

Even though the internals will not be on display, clean cable management was important. The cables needed to stay in place despite lots of transportation jolts.

Routing internal cables during assembly

The final result was very clean and featured the Livestream USB license dongle mounted internally in the case.

Assembled PC with cover removed


Before deploying the system, every component was tested.

Test bench with multiple components connected for testing purposes

The end product fit inside two Pelican 1650 cases. The recording HDD fit inside a separate hard case because the drive would be transferred frequently from our location to another location for video editing.

Two Pelican 1650 cases

The computer case and cameras fit into one Pelican 1650. Everything else, including all wiring, controllers, keyboard, and the LCD monitor all fit into the other case.

Assembled cases open with computers and equipment

The system was deployed and thankfully everything worked!

System in use at church

Five months later

We made a few improvements after the first use of this system.

Camera support in the middle of a theater

We initially planned to place the cameras on high ledges in the theater. Instead, we opted to place one camera on a lower ledge and the other on a stand. A traditional tripod would not work for the space, so we used a OnStage studio monitor stand. We used velcro on the camera and monitor base to keep it from moving or falling off and a sandbag on the base to prevent the stand from tipping over.

After a few weeks, one of the plastic feed on the bottom of the stand fell off. This caused the camera to be slightly off-level and took me a while to figure out what was causing it.

Loose cabling

A few weeks after the initial deployment, one day the computer failed to turn on. I opened the case and everything looked okay. After pulling gently on the modular power supply’s cables, I noticed the CPU power connector became loose. It has not become loose again after re-seating it, but I’m glad I was the one volunteering that day!

Cable management

I initially purchased a “cable dropover” to hide the camera’s SDI and power cables across the floor in a very high traffic area. However, the dropover was difficult to use and store. We instead switched to a Safcord cord protector which hooks to carpet and is very easy to setup and teardown. Safcord is awesome!

We also had long cable runs between cameras. I used some cheap generic Kootek neoprene cable management sleeves which were very easy to use and keep everything tidy in a long cable snake between cameras.

Color consistency

We noticed our PTZOptics cameras tend to acquire a color cast depending on the graphics we display on our projector. To work around this problem, I manually set Auto White Balance off and manually set color temperature on both cameras. This makes our color consistent even as the background and stage lighting changes.

Livestream software

Everything pretty much works. With two 1080p cameras via SDI, a virtual network camera capturing audio and video from ProPresenter, occasional media playback of videos presented during services, and various graphics layers to show sections of the slide display for lyrics, the computer handles all of this without any problem. CPU usage is normally around 30% and can get as high as 70% or so.

We’ve never had a software problem which impacted our broadcast, which is great.

I do notice some visual glitches during complex transitions, and some keyboard focus issues which can cause keyboard hot keys to fail to work until I click and re-focus the UI. These issues are odd for professional and expensive software, but they are minor and easy to work around.


Overall, this was a very cost effective build and served us for a long time. This computer was stolen in 2019 and we rebuilt a rackmount version which I’ll write about in the future.

The Joy of Migration

I recently purchased a MacBook Pro. I was eagerly expecting a seamless setup experience.

The experience was not seamless. The good news is I have a working system. The bad news is it took a while to get here. I’m writing my experience to help others who may also be setting up a new Mac and trying to get things to work.

Gentleman’s Ride Recap

You can donate for 2017! Donate now.

Last Sunday was an unforgettable day riding through SF and across Golden Gate. We rode united to fight male suicide and prostate cancer and had a great time doing it.

Why I am asking for your support

Men are dying too young.

Prostate cancer kills more men than breast cancer in women.

I lost a male co-worker to suicide, which is the biggest killer of men aged 20-39.

This needs to change.

That’s why I have been partnering with these fine folks riding for a cause — the Distinguished Gentleman’s Ride — to raise funds that directly support the fight for men’s health worldwide.

Prostate cancer statistics

  • Prostate cancer is the most common cancer in men. It kills more men than breast cancer in women.
  • One in seven men will develop prostate cancer by the age of 75, and one in four men will be affected by the age of 85.
  • Close to 500,000 men will die from prostate cancer yearly.

Suicide prevention

  • Suicide is the biggest killer of men aged 20-39, with ¾ of all suicides being male.
  • 510,000 men die from Suicide each year, one every minute.

These numbers need to drastically change.

Personal fundraising goal reached

I have had a few fine folks give generously before the ride: $522.40 contributed for men’s health. Thank you. You have personally contributed in funding worldwide medical research to find a cure for prostate cancer, as well as aiding to improve men’s mental health.

$1.5M to go worldwide

Fundraising is still open until October 31. If you haven’t yet donated, please consider registering your support.

Curious about what programs your donation will support? In partnership with the Movember Foundation, funds are allocated to important prostate cancer research programs as well as men’s mental health and suicide prevention programs.

All fundraising has only been made possible through the generosity of people like you who have answered the call to make the world a better place. DGR has a goal of $5M and $3.4M have been raised so far. Help us get to the end!

Donate now.

San Francisco ride

The ride was pretty incredible. Over 350 people turned out. Together we raised $55,511.

This short video gives you a taste of what it’s like:

Having a blast on two wheels in San Francisco. ? Join us and support men's health. $522 raised as of today by my amazing supporters. Link in bio. Music by HOME.

After riding across the Golden Gate we stopped at Equator Coffee, where we all took some time to drink cold brew, recognize the top fundraisers, and even the best dressed gentleman and gentlelady along with best motorcycle. And, I took home an Iron & Resin t-shirt as a runner up for best beard. Tip of the hat to Riv at Paradox for keeping me looking sharp.

Support male suicide prevention

Today is World Suicide Prevention Day. I lost a coworker to suicide a couple years ago. Half a million men will commit suicide this year.

Depression doesn’t discriminate. Guys, don’t “tough it out” in silence. Talk to somebody. You can always speak with somebody immediately at 1-800-273-TALK.

I am partnering with The Distinguished Gentleman’s Ride to support male suicide prevention. Please consider making a donation to support these efforts. Male suicide is a tragedy that must be prevented.

  • Suicide is the biggest killer of men aged 20-39, with ¾ of all suicides being male.
  • 510,000 men die from suicide each year, one every minute.

This video from the Movember Foundation is a powerful reminder to all men to talk to somebody when in a time of crisis. If you or someone you know is in crisis, check out these resources and start a much needed conversation today.

Buckminster Fuller’s FBI File

Matt Novak shares Buckminster Fuller’s FBI file:

Buckminster Fuller was a world-renowned architect, math-obsessed designer, and affable weirdo. He died in 1983, but Fuller is still remembered fondly today for his geodesic domes and his three-wheeled cars. Despite extensive historical interest in the man, his FBI file has never been made public. Until now.

Redacted file.

Turns out the FBI was interested in him because of his association with Soviets during the Cold War.

Carbondale interview.

Pretty cool to see my hometown of Carbondale, Illinois all over his file. He lived there in a geodesic dome, which I remember from my childhood.

New Heart, New Mind

I used to believe I’d be remembered for my work.

Not anymore.

Life is about relationships with people, not bits. What’s valued is availability, truly caring for those around you, and expecting nothing in return.

I’m being remembered for my love.

When I was a child, I spoke like a child, I thought like a child, I reasoned like a child. When I became a man, I gave up childish ways.
1 Corinthians 13:11 ESV

A year ago, someone great told me: “Do not love efficiently.” 1

What a thought! As an engineer, efficiency comes hardwired.

Loving inefficiently means caring for people when it feels like a waste of time, when it’s with someone outside of “my set”, when it’s someone I don’t understand and honestly don’t want to understand.

I recall this advice in places I’d typically keep to myself. Places like airplanes, coffee shops, and urban sidewalks. Neighbors, baristas, and solicitors.

My selfishness abrades at these attempts. But what is our legacy without love? What else is more important?

If I give away all I have, and if I deliver up my body to be burned, but have not love, I gain nothing.
1 Corinthians 13:3 ESV

These encounters are usually brief. Sometimes they’re awkward. But in engaging, I find myself challenged by the everyday opportunities to love others in this way:

Love is patient and kind; love does not envy or boast; it is not arrogant or rude. It does not insist on its own way; it is not irritable or resentful; it does not rejoice at wrongdoing, but rejoices with the truth. Love bears all things, believes all things, hopes all things, endures all things.
1 Corinthians 13:4-7 ESV

This is hard. It can come easy, but it’s usually difficult. There are cycles of generosity followed by self-serving deceit.

I can’t love like this. These cycles reveal it: human nature is at odds with acting this way. We love for a day, then we fall short. We try not to envy, then find ourselves coveting. We are nice to people until we feel justified to retaliate. And how do we endure all things when we’re broken in the midst of disappointment?

Instead of making adjustments to what’s broken, my old self is being replaced.

1 Corinthians 13 describes the result of radical transformation.

This chapter of the Bible was written to show the fruits of a new life in Jesus, when we’re committed to Him as our Savior and have the Holy Spirit working within us.

There are days where I progress in love and days where I miss the mark.

I don’t understand everything about the Bible. I’m learning, but I don’t know it all. I will always be learning. But I know a few things for sure. I have admitted to myself and God that I can’t love like this alone. That I cannot be close to God merely by being a good person doing good things. That I believe God’s only son Jesus is the perfect sacrifice that allows God to transform our entire soul if we ask Him.

By this, I am accepted before I did anything to deserve acceptance. Adopted. Beloved. Out of this new identity, I am able to share this unconditional love with others. It’s the heart of Christianity.

“Teacher, which command in God’s Law is the most important?” Jesus said, “‘Love the Lord your God with all your passion and prayer and intelligence.’ This is the most important, the first on any list. But there is a second to set alongside it: ‘Love others as well as you love yourself.’ These two commands are pegs; everything in God’s Law and the Prophets hangs from them.”
Matthew 22:35-40 The Message

Old and New

This scene is full of people who compared how they used to live compared to who they are becoming in Jesus.

I’m a work in progress and frequently mess up. We all do. I desire a new heart, a new mind, seen dimly and in part.

By the act of trusting Jesus, I surrender everything to the process of transformation. Every day I’m becoming a new person that can love the way I’m designed to love.

Radically and inefficiently.

The happy man is he who lives the life of love, not for the honors it may bring, but for the life itself.
Raymond John Baughan (1946)

Finally, if you’d like to know more about what I started to share here, you’re invited to check out The Touch of God. It’s a video from my church about God’s love in a loud and busy world. Or maybe just visit a church near you. You can expect to find a bunch of folks who have been through some crap and are figuring this all out together. See you out there.
