You Can (Not) Build a Pro Video Camera App in Four Months

It’s been seven years since we launched a little side project, Halide. We built it for us: we didn’t set out to ‘disrupt’ the world of camera apps, or get rich. We wanted to build a beautiful, powerful, and delightful camera app that we would enjoy using.

Working on finishing up Halide 1.0 — May 2017

It exceeded our wildest expectations and quickly grew to become an award-winning photography app and a legitimate business. Soon, we quit our jobs to work on apps full-time. Yes, that’s plural, apps.

From what we learned building Halide full-time, we spun out one-off projects such as Orion and Spectre (that one went places — a little long exposure app that won 2019 App of the Year). While these were fun diversions, Halide remained the focus of our company. It was what we worked on most days of the week, for the last seven years.

There was just one thing we knew we’d never add to Halide: video. Ever since Halide 1.0, users asked for it, but we knew it wouldn’t work. Photography and cinema are different mediums that call for different user experiences.

Instead, Sebastiaan and I talked about building a completely separate app, a “Halide for video.” Talk never went past the “Wouldn’t it be cool…” phase, because we weren’t sure if we could juggle a second major app. We’re a small team. Ridiculously small. One designer and developer.

We knew expectations were sky high, and honestly, nothing excited us about iPhone video. It felt photography was at the forefront of the camera innovations.

Our attitude quickly changed in November 2023, and we launched our video app, Kino, six months later. This is the story of why we made the plunge, its whirlwind development, the results, and where we go from here.

Fall 2023: “How hard could it be?”

At the end of last summer, Sebastiaan and I launched Orion, a free app that helps turn your iPad into an HDMI monitor.

We normally take our time with new projects. Both Halide and Spectre each took one year to ship (though, in our defense, these started as side projects). Orion was a fun challenge to see if our two-man company could ship a brand-new app in 45 days, and it went really well. It reset expectations of what we could accomplish quickly, but it felt a bit exhausting toward the end.

We expected to spend the rest of the year slowing down and turning our attention to Halide. We were in the home stretch of a brand new feature that we were very excited about, and with another month or two of work, we could bring it across the finish line.

I could also use a little breather for the rest of the year, as I expected my first kid at the end of February.

Those plans changed moments after the Orion release, with Apple’s unveiling of the iPhone 15 Pro. We watch every keynote paying close attention to changes in photography, which we’ll weave into our fall Halide update. This time we were blown away by the announcement of “log video.”

Log video is a very big deal. It contains much more information than conventional iPhone video, allowing ridiculous control over the final image. Apple called it Apple Log. Of course.

Apple Log video is fantastic for professional-looking video — but it requires some editing.

As Apple Log made waves in the filmmaking community, we got a sense of déjà vu. Our minds went back to the Summer of 2016, when Apple iPhones would soon capture RAW photos, allowing incredible editing superpowers. Sebastiaan and I felt that was the right time to build Halide. Now, with Apple Log, we felt iPhone video was about to have its RAW moment.

That said, there are only so many hours in the day. Could we add another major app to our portfolio without supporting ou breadwinner, Halide?

Well, Halide is overdue for a refresh. Its foundations were built seven years ago, and Apple’s newer technologies would vastly improve the product. Orion wasn’t just a fun side project, it was a test as to whether Apple’s new technologies were mature enough to start rolling into Halide. If so, how much do they improve our productivity? The result was “yes,” and “a ton.” We were able to accomplish some tasks for Orion in hours that would take days in Halide.

But Orion wasn’t nearly as complex as Halide. Our video app would let us build a foundation for the future. While our photo and video apps would never share user interfaces, we could architect them to share underlying technologies. If we do this right, we can manage the workload.

The Deadline

Maybe the hardest part of our job is planning everything around Apple’s schedule. We spend summers readying our apps for the Fall iOS release, which launches alongside new iPhones. Then we scramble to test our apps and support the new camera hardware. If we’re lucky, we get six months a year to define our product direction.

Our desk is always a pile of iPhones of various generations – and the pile grows every fall.

That said, constraints help you focus. We decided that Orion had to launch when iOS 17 dropped, because we expected lots of similar apps to pop up over time, and we wanted to be there right out of the gate. Orion had to ship in 45 days, so we made it work.

I’m not advocating crunch time, where developers work long hours for the sake of unrealistic deadlines. Quite the opposite. Deadlines force us to accept that we won’t get everything done in 1.0. We have the freedom to cut as many features as needed to keep things sustainable. The old adage goes, “Work expands so as to fill the time available for its completion,” but can’t the same be true for work shrinkage?

The question was whether we could ship a whole new camera app within four months, before my baby’s due date. It might sound ridiculous, given Halide 1.0 took one year to ship, but Orion proved how much more productive we could be with the latest technology, and this time we were building a camera with seven years of experience in Apple’s AV stack.

One reason that Halide and Spectre each took a year was that we handled 100% of each project ourselves. With Orion, we worked with Anton Heestand on its wonderful over-the-top onboarding, and Cabel Sasser wrote us an intro song! It turns out we can delegate work and collaborate with friends without losing any character.

The biggest risk with our four-month deadline had nothing to do with code. We were worried that we didn’t yet understand what we were building. There were already plenty of free apps that let you record Apple Log. What could our new app bring to the table?

Defining the Product

After surveying the app landscape, we quickly realized that every app that supports Apple Log targets advanced users. These types of users look at a high-end camera rig and go, “Wow! Cool!”

If you look at this and you go ‘hell yeah’, yes, you are that kind of user.

Don’t get me wrong, we love this stuff, but we weren’t excited to build a high-end tool exclusive to pros. But as we dug into the techniques of filmmaking, I had a flashback to the late 90s and early 2000s. I grew up on the cusp of digital filmmaking and had lots of fun making short movies with friends.

Tequila (2006)

In the mid-2000s, we used a ridiculous camera that had been modified to shoot 10-bit log footage. That hacked camera required a handful of portable hard drives that would overheat at the worst times, but these technical shenanigans piqued my
curiosity, and led me down a path where I now build camera apps for a living.

Returning to the world of filmmaking excited me. I could build an app for 99% of people just starting who wish they could record beautiful, cinematic videos, but can’t make heads or tails of “colorspaces” or “shutter angles.” I had the chance to
build the camera I wish I had decades ago.


If we have one guiding principle, it’s the belief that “intuitive” and “powerful” do not have to be mutually exclusive. We thought our app could deliver 95% of the features demanded by high-end professionals without making the app too complex for novices. We’d start with an approachable 1.0, and carefully layering on more advanced features over time.

It turned out, Sebastiaan had been quietly designing concepts for a video app for quite a while. This is how early some of Kino’s most recognizable visual elements were born, like the recording tally light ring that follows the curvature of your iPhone’s screen, or the little segmented audio levels.

one of Sebastiaan’s early Sketch explorations of a video app, codenamed ‘Amalfi’

That said, the worst way to explore a product is with a pixel-perfect version. A beautiful UX takes extra time, and pretty images can distract you from fundamental problems. So in the interest of speed, I spent the next few weeks focusing on a functional prototype that resembled Sebastiaan’s concepts. It could record Apple Log footage, connect to an external microphone, and let us quickly experiment with UI concepts.

We call this style ‘brutalist’

In December 2023, just as our prototype built momentum, news broke that Filmic Pro— the most popular filmmaking app on the App Store— was shutting down. This left a vacuum in the ecosystem of filmmaking apps and a material loss in our tiny community of camera apps.

Normally, we don’t pre-announce products. Part of it might be Sebastiaan’s ex-Apple penchant for secrecy, to announce stuff and surprise and delight. But it also raises expectations and runs the risk of committing to features that might not work out. At the same time, the demise of Filmic was an invaluable opportunity to announce our new app and test demand. We decided to pre-announce.

First, our app needed a name, and we didn’t want to repeat the pronunciation ambiguity of “Halide.” (Note: Sebastiaan says Hey-lide, and I say Hal-ide, but we switch every other week.) Sebastiaan floated a name that both encapsulated ‘craft video’ and sounded friendly: Kino.

I spent 24 hours shooting an announcement video with our alpha build, and we launched a teaser page at shotwithkino.com.

The reception to our video was overwhelmingly positive, and it felt like we had a hit on our hands.

Now we just had to ship it. Wait… what were we shipping?

December: Instant Grade

Sometimes building products is like writing a story. Writers don’t go, “Once upon a time,” and finish the story in one pass. Many writers approach a blank page with ideas for characters, major plot points, and themes running through their heads. The hard part is forming loose ideas into a cohesive structure. It’s called “cracking the story,” and there’s a similar process in building products.

We decided a good starting point was to shoot videos. When you’re forced to eat your own dog food, you quickly figure out what works and what doesn’t. In a meta turn of events, we made a video about making Kino.

We appreciated the natural look of Apple Log footage, as it didn’t have the same post-processing you see in iPhone video. The hard part is giving log footage a nice treatment. Straight out of the camera, Apple Log looks… uh…

A frame from an Apple Log video. By design, log video is quite washed out.

Log footage is supposed to look that way. It just contains the ingredients that can make up gorgeous images, and it’s your job to bake them. You’re supposed to bring it into a high-end tool like Davinci Resolve to “color grade” it. While these tools feel empowering to professionals, to a novice, they feel as intuitive as the cockpit of a commercial airplane.

We knew Kino could be a game changer if it let everyone grade their footage right in the app with a tap, by using a handful of packaged presets.

But why stop there? We could let you import a preset from anywhere. Apple Log was only a month old, but pros were already selling great grade packs, ready to be imported into your favorite editing suite.

We saw that people like Evan Schneider and Tyler Stalman had made some beautiful presets.

And if you’re a high-end user, you could even author your own looks in Resolve! Speaking of the high end…

Tackling the High End

On the other end of the spectrum, we had to figure out what professionals demand. We packed up and flew down to Los Angeles, where Sebastiaan booked us into the only NFT hotel in town (Sebastiaan Note: So sorry, I had no idea).

Drones setting a new standard in ocean rescue technology

Drones setting a new standard in ocean rescue technology


Last month, two young paddleboarders found themselves stranded in the ocean, pushed 2,000 feet from the shore by strong winds and currents. Thanks to the deployment of a drone, rescuers kept an eye on them the whole time and safely brought them aboard a rescue boat within minutes.

In North Carolina, the Oak Island Fire Department is one of a few in the country using drone technology for ocean rescues. Firefighter-turned-drone pilot Sean Barry explained the drone’s capabilities as it was demonstrated on a windy day. 

“This drone is capable of flying in all types of weather and environments,” Barry said.

Equipped with a camera that can switch between modes — including infrared to spot people in distress — responders can communicate instructions through a speaker. It also can carry life-preserving equipment.

The device is activated by a CO2 cartridge when it comes in contact with water. Once triggered, it inflates into a long tube, approximately 26 inches long, providing distressed swimmers something to hold on to.

In a real-life rescue, after a 911 call from shore, the drone spotted a swimmer in distress. It released two floating tubes, providing the swimmer with buoyancy until help arrived.

Like many coastal communities, Oak Island’s population can swell from about 10,000 to 50,000 during the summer tourist season. Riptides, which are hard to detect on the surface, can happen at any time.

Every year, about 100 people die due to rip currents on U.S. beaches. More than 80% of beach rescues involve rip currents, if you’re caught in one, rescuers advise to not panic or try to fight it, but try to float or swim parallel to the coastline to get out of the current.

Oak Island Fire Chief Lee Price noted that many people underestimate the force of rip currents.

“People are, ‘Oh, I’m a good swimmer. I’m gonna go out there,’ and then they get in trouble,” Price said.

For Price, the benefit of drones isn’t just faster response times but also keeping rescuers safe. Through the camera and speaker, they can determine if someone isn’t in distress.

Price said many people might not be aware of it. 

“It’s like anything as technology advances, it takes a little bit for everybody to catch up and get used to it,” said Price.

In a demonstration, Barry showed how the drone can bring a safety rope to a swimmer while rescuers prepare to pull the swimmer to shore.

“The speed and accuracy that this gives you … rapid deployment, speed, accuracy, and safety overall,” Price said. “Not just safety for the victim, but safety for our responders.”

SpaceX to launch bitcoin entrepreneur and three crewmates on flight around Earth’s poles

SpaceX to launch bitcoin entrepreneur and three crewmates on flight around Earth's poles


A blockchain entrepreneur, a cinematographer, a polar adventurer and a robotics researcher plan to fly around Earth’s poles aboard a SpaceX Crew Dragon capsule by the end of the year, becoming the first humans to observe the ice caps and extreme polar environments from orbit, SpaceX announced Monday.

The historic flight, launched from the Kennedy Space Center in Florida, will be commanded by Chun Wang, a wealthy bitcoin pioneer who founded f2pool and stakefish, “which are among the largest Bitcoin mining pools and Ethereum staking providers,” the crew’s website says.

“Wang aims to use the mission to highlight the crew’s explorational spirit, bring a sense of wonder and curiosity to the larger public and highlight how technology can help push the boundaries of exploration of Earth and through the mission’s research,” SpaceX said on its website.

Wang’s crewmates are Norwegian cinematographer Jannicke Mikkelsen, Australian adventurer Eric Philips and Rabea Rogge, a German robotics researcher. All four have an interest in extreme polar environments and plan to carry out related research and photography from orbit.

The mission, known as “Fram2” in honor of a Norwegian ship used to explore both the Arctic and Antarctic regions, will last three to five days and fly at altitudes between about 265 and 280 miles.

“This looks like a cool & well thought out mission. I wish the @framonauts the best on this epic exploration adventure!” tweeted Jared Isaacman, the billionaire philanthropist who charted the first private SpaceX mission — Inspiration4 — and who plans to blast off on a second flight — Polaris Dawn — later this month.

The flights “showcase what commercial missions can achieve thanks to @SpaceX’s reusability and NASA’s vision with the commercial crew program,” Isaacman said. “All just small steps towards unlocking the last great frontier.”

Like the Inspiration4 mission before them, Wang and his crewmates will fly in a Crew Dragon equipped with a transparent cupola giving them a picture-window view of Earth below and deep space beyond.

No astronauts or cosmonauts have ever viewed Earth from the vantage point of a polar orbit, one tilted, or inclined, 90 degrees to the equator. Such orbits are favored by spy satellites, weather stations and commercial photo-reconnaissance satellites because they fly over the entire planet as it rotates beneath them.

The high-inclination record for piloted flight was set in the early 1960s by Soviet Vostok spacecraft launched into orbits inclined 65 degrees. The U.S. record was set by a space shuttle mission launched in 1990 that carried out a classified military mission in an orbit tilted 62 degrees with respect to the equator.

The International Space Station never flies beyond 51.6 degrees north and south latitude. NASA planned to launch a space shuttle on a classified military mission around the poles in 1986, but the flight was canceled in the wake of the Challenger disaster.

“The North and South Poles are invisible to astronauts on the International Space Station, as well as to all previous human spaceflight missions except for the Apollo lunar missions but only from far away,” the Fram2 website says. “This new flight trajectory will unlock new possibilities for human spaceflight.”

SpaceX has launched 13 piloted missions carrying 50 astronauts, cosmonauts and private citizens to orbit in nine NASA flights to the space station, three commercial visits to the lab and the Inspiration4 mission chartered by Isaacman.

Isaacman and three crewmates plan to blast off Aug. 26 on another fully commercial flight, this one featuring the first civilian spacewalks. NASA plans to launch its next Crew Dragon flight to the space station around Sept. 24.

Finally, a screen that goes anywhere

Finally, a screen that goes anywhere

Today we’re launching a totally new, totally different app. Meet Orion.

Orion is a small, fun app that helps you use your iPad as an external HDMI display for any camera, video game console, or even VHS. Just plug in one of the bajillion inexpensive adapters, and Orion handles the rest.

But wait — we’re a camera company. Why an HDMI monitor?

We built this to scratch a few itches. First, in professional cinematography, it’s common to connect an external screen to your camera to get a better view of the action. Orion not only gives you a bigger screen, but you can even share screenshots with your crew with a couple of taps.

We also built this for… pure fun. When traveling with a Nintendo Switch, it’s a delight to play games on a bigger screen, especially alongside friends.
