Highlight Reel · Part 1 of 6

One Moment Worth Keeping

The AI finds the best moment in any video. Since Saturday, it only finds one kind.

6 min read

"Every video has one moment worth keeping," Dez said. "Clips.com finds it."

He said it to the mirror in the bathroom. He said it to the coffee machine. On Thursday afternoon, four days before the most important meeting of his life, he said it to me. I was eating soup at my desk.

"I know," I said. "I built the part that finds it."


My name is Wren Abernathy. I'm thirty-one, and I'm the only machine-learning engineer at clips.com. That sounds impressive until you learn there are five of us in total. One of the five is a ficus.

Clips.com does one thing. You upload a video, any video, and our model watches all of it. Then it hands back the single best moment, trimmed and ready to share.

A two-hour wedding becomes nine seconds of the first dance. A ninety-minute soccer match becomes the goal.

The model is called Kestrel. I named it after a small bird that hovers in place and waits for the one thing worth diving at. Dez wanted to call it ClipBot. We compromised by doing what I said.

Our office is a former dentist's suite above a laundromat. The chairs still recline. Every afternoon at three, the dryers downstairs hit their spin cycle, and the floor hums like a polite earthquake.


Desmond Kalloway is twenty-nine and has started two companies. The first one was called Lunchly. It delivered lunch. It also ran out of money in front of an investor, during the pitch, when the investor's lunch arrived from a competitor.

Dez does not talk about Lunchly. He talks about being lean.

"We're lean," he says, when he reuses a tea bag. "We're lean," he says, when he cancels the second monitor I ordered. He once tried to bring a toaster from home and expense the bread.

He wears the same gray hoodie every day. He says it frees up decision-making energy. I've seen his closet on a video call. It contains eleven gray hoodies and one suit, still in the dry-cleaner's plastic, waiting for Monday.

"Ninebark Capital," he said now, standing over my soup. "Harriet Voss. Monday at ten. If she says yes, we survive the year."

"And if she says no?"

"We become a company that used to be clips.com." He said it lightly. His left eye twitched.


Everyone in our small industry had a Harriet Voss story. She was fifty-eight and had funded nine companies in twenty years. Seven of them still existed, which in our world is a miracle.

She was famous for asking exactly one question per pitch. Nobody knew in advance what it would be.

A founder I'd met at a meetup said his had been, "What's the worst thing your product has ever done?" He had answered honestly. She had funded him on the spot.

Another founder had been asked, "Why are you sweating?" She had not funded him.

"What if she asks why I'm sweating?" Dez said.

"You're not sweating."

"I will be. On Monday. I can feel it scheduling itself."


The rest of clips.com was in the reclining chairs, pretending not to listen.

Marguerite Fenwick, forty-seven, ran operations. In practice, that meant Marguerite ran everything that wasn't code or Dez. She paid the bills and fixed the printer. She once talked our landlord out of a rent increase by describing the laundromat's ventilation in a tone he could not survive.

She also had three cats and a powerful allergy to all of them. She refused to give up either.

Marguerite sneezed in sets of exactly three. Never two. Never four. She counted them out loud, like a referee.

"That's one," she said, as I watched. She held up a finger.

"That's two."

We waited. The whole office waited. It was a ritual by now.

"That's three." She folded her hands. "Carry on."

"Bless you," said three voices in unison. The ficus did not participate.


The third voice belonged to Tobias Quill. He was twenty-four and labeled our training data. For ten hours a day, he watched videos and marked the best moment in each one, so Kestrel could learn what "best" meant.

Watching that much video had changed him. Tobias now narrated his own life in the style of online clip titles. He couldn't stop. I'm not sure he tried.

"Man Eats Soup At Desk," he said, glancing at me. "You Won't Believe What Happens Next."

"Nothing happens next," I said.

"Engineer Denies Anything Happens Next. Gone Wrong."

Dez clapped his hands. "Okay. Listen up. The demo."

Tobias leaned toward Marguerite. "Founder Addresses Team. Emotional."


The plan for the demo was simple. We would show Kestrel working on sports, weddings and birthday parties. Those were the clean categories. Kestrel was good at them.

Dez wanted more.

"Harriet Voss doesn't care about weddings," he said. "She's seen a thousand weddings. I want her to see it work on real life."

"Real life."

"Messy life. Offices, meetings, people."

"We don't have training data for offices," I said.

"We have the all-hands recordings."

He was right, technically. Marguerite recorded every monthly all-hands meeting on a tripod in the corner. She said it was for the minutes. I suspected it was for leverage.

There were eighteen months of them. Eighteen hours of clips.com arguing about snacks, standing desks, and whether the ficus counted as a mascot.

"If we add those to the training set tonight," Dez said, "Kestrel learns offices over the weekend. Monday, we show her something nobody else can do."

"A training run over a weekend is how you get surprises," I said.

"Surprises are good."

"Surprises are good at birthday parties. They're bad in production."

He gave me the look. It was the look of a man who had once watched an investor's lunch arrive from a competitor. I have never been able to argue with that look. Nobody has.

"One run," I said. "I keep the current version as a backup. If anything looks strange, we roll back and demo what we have."

"Deal," Dez said. "Thank you. We're lean, but we're bold."

"That's not a saying."

"It is now."


Friday evening, at seven-fourteen, I started the training run.

Tobias had labeled the all-hands videos over the afternoon at triple speed. He'd marked the best moment in each one. I didn't check his labels as carefully as I should have.

It was Friday. The dryers were humming. Marguerite had just sneezed three times and gone home.

I watched the progress bar start to crawl. Thirty-eight hours, it estimated. It would finish Sunday morning, which gave us a day to test.

Dez stood in the doorway with his backpack on. He looked at the bar the way some people look at a lottery draw.

"You okay?" I asked.

"Fine. I don't get nervous." He almost sneezed into his elbow. He stopped it halfway, like a man catching a falling vase.

"I also don't sneeze," he said. "I don't have time for it."

"That's not how sneezing works."

"It's how founding works." He turned off the light, then turned it back on because I was still in the room. "Goodnight. Every video has one moment worth keeping."

"Goodnight, Dez."


I came in on Saturday morning to check on the run. I'd meant to wait until Sunday. I didn't sleep well.

The run had gone faster than estimated, which never happens. It said COMPLETE in calm green letters.

Kestrel had trained on the new data and quietly replaced itself on our servers. That was how Dez had wanted the pipeline set up. Fewer steps. Lean.

I told myself that was fine. I still had the backup.

I picked a test video at random from our library. It was a wedding: two hours and six minutes of a couple in a garden.

I'd run it a hundred times before. Kestrel always picked the moment the couple turned to face their guests. It was reliable, sweet, and safe for an investor meeting.

I uploaded it to clips.com and pressed the button.

The progress wheel spun. The laundromat downstairs started its first load of the day. I drank my coffee and waited for the couple to turn around.

The clip came back. It was four seconds long.

It showed a great-uncle in the third row, in a brown suit, during the vows. His face scrunched. His shoulders rose. And then, with the force of a man who had been holding it in since the processional, he sneezed.

Kestrel had given it a confidence score of ninety-nine percent. Its highest ever.

I stared at the screen. I ran the video again.

Same clip. Same uncle. Same score.

Then I ran a different video, a birthday party, and waited.

The clip came back. It was a man in a paper hat, sneezing into a cake.

Up next: Bless You
