"Be patient and consistent. Once you have built something, others will support you, and it gets easier."

Sergio Miranda started as an assistant editor on reality TV. Twenty years later he runs Serril Media, the post house behind everything from Deadliest Catch to indie documentaries. This is how he got there, in his own words.

He started at the bottom of the post-production ladder, the way most editors do, as an assistant on reality television. It is the job nobody puts on a highlight reel: syncing footage, managing media, sorting other people's takes deep into the night while someone else makes the cut. He did it for years. He paid attention.

What he learned in those rooms was not just how to edit. It was patience. "Be patient and consistent in your work," he says now, two decades in. "Once you have built something, others will support you, and it gets easier." He says it like a man who has tested the claim.

The company he built with his wife

The turning point was not a credit. It was a decision. Other editors kept telling him the same thing: stop freelancing like a freelancer. Form a company. So he and his wife, April, started Serril Media, at first for the most unglamorous reason imaginable, to "better control my money, tax strategy and monthly cash flow."

That small administrative act changed everything. Once Serril Media existed, he could go after bigger work, and the bigger work came. Netflix. HBO Max. Discovery. Hulu. Facebook Watch. Projects most people would recognize, Deadliest Catch: Bloodline, work with JoJo Siwa, a Peacock podcast he lead-edited, an HBO documentary where he set up the entire workflow and wrangled over a hundred terabytes of 4K media so nothing got lost. April runs it with him as executive producer. The company that started as a tax strategy became a family business with his name on the work.

He has a philosophy for the hard days, and it is not from a film school. It is from a small book, The Four Agreements by Don Miguel Ruiz. Be impeccable with your word. Don't take anything personally. Don't make assumptions. Always do your best. "Simple rules," he says, but he reaches for them "in the most stressful situations with work." Twenty years in post-production, and the thing he leans on hardest is a set of agreements about how to treat people.

The eight-year film

What keeps him in it is not the deadlines or the deliverables. It is the people he gets to make things with. "Collaborating with other artists and creative people helps me evolve my artistic skills and perspective," he says. You can hear it in how he talks about the work that means the most to him, which is rarely the work with the biggest logo attached.

There was one project that lived closest to that nerve. A passion project, the kind you make because you have to, not because anyone is paying you. It had been filming for more than eight years and gathered over forty interviews along the way. Eight years is a long time to hold a story in your head. By the time he sat down to shape it, the footage had grown into something almost too big to face, a room full of voices with no obvious door in.

That was the moment a new tool walked into his twenty-year-old craft. He had started testing Eddie, an AI assistant editor, to see how far it could take a rough cut. On the passion project he pointed it at the exact place the volume hurt most. "It really helped in the moments where we needed to analyze a lot of media," he says. He could hand it a script or the timecodes from his transcript, and it would string the selects out for him, right inside his Premiere Pro timeline, multicam and all, so an editor could get to the material quickly instead of drowning in it. Not the finished film. A way back inside it.

He is honest about where it stops, the same way he is honest about everything else. The tool can organize the footage. It cannot yet feel what a story is about. He once used it on an edit about an LA conservationist describing how bats live in the city and gather around stadiums like Dodger Stadium and USC, and the tool missed the whole thread, missed anything tied to LA, because nothing had told it what mattered. What he wants is a way to hand it a creative brief first, a story compass, so it goes looking for the moments that match the film in his head. For now, that part is still the editor's, and he likes it that way.

No rules yet

Ask him whether another editor should try a tool like that, and he does not preach. He shrugs, in the way of a man who has watched a dozen technologies come and go across twenty years. "Play with it. Treat it as a tool," he says. "It's new to the market, so there are no rules yet on how to use it." Coming from someone who learned every rule in post the slow way, one patient reality-TV night at a time, it is not a small thing to say.
