A Real Walkthrough 12 min read · Updated August 26, 2026 ![How to produce a documentary: the slate before a Fund Black Tech interview take](https://c-istudios.com/wp-content/uploads/2026/08/fbt-slate-hero.webp) Most guides on how to produce a documentary describe a process. This one describes a production. Fund Black Tech, the series C&I Films shot about who gets funded in technology, ran three years from the first shoot in March 2021 to pickups in 2024. Twelve people sat down with us across New York, Los Angeles and Washington DC. What came back fills close to 23 terabytes of RED raw across nineteen drives, and the edit is still running. Below is the order the work actually happened in, including the parts that took the longest and never show up on screen. ## How to produce a documentary, in the order the work happens Feature documentaries do not move in a straight line the way a commercial does. Development and production overlap for years, and post starts before the last interview is shot. Still, the work has a shape, so look at the whole of it before you price any one piece. Phase What it actually involves What it looked like on Fund Black Tech Development Finding the question, testing whether anyone will answer it on camera An idea and nothing more, for months Outreach and scheduling Cold emails, calls, follow ups, holding a crew against a date that is not locked Weeks of coordination per interview day Scouting and set design Walking the room, hearing the room, dressing it, building it if a venue will not work Rented locations dressed properly, plus full sets built in our Los Angeles studio Research and scripting A separate line of questions for every subject, on one theme Twelve scripts, one theme Production Crew, cameras, sound, and one sitting per person Twelve interview days, the largest running five cameras plus a separate audio recorder Data management Offloads, checksums, redundancy, labelling Close to 23 TB of RED raw across nineteen drives Archival and clearance Sourcing, verifying and clearing anything you did not shoot Public domain material on Tulsa in 1921, the Freedman’s Bank and the Great Migration Post Transcribe, score, assemble, restructure, cut down, grade, mix A first assembly past three hours, then eight chapters, then a selects edit If you want the shorter version of this arc without the production detail, our post on [documentary filmmaking from concept to final cut](https://c-istudios.com/documentary-filmmaking-from-concept-to-final-cut/) covers the same ground at a higher altitude. ![Producers coordinating documentary interview scheduling on location](https://c-istudios.com/wp-content/uploads/2026/08/fbt-scheduling-laptops.jpg) ## Booking the people is the real first job Everything people write about how to produce a documentary starts with the idea. In practice it starts with access. Nothing exists until somebody agrees to be in it. Every interview in the series started as an email or a phone call to a person who had no particular reason to hand us a day of their time. Most took several rounds of back and forth before a date existed at all. That is its own job, and it is the one first time producers underestimate. You are keeping lines open with a dozen busy people at once. You are following up often enough to matter without becoming a nuisance. You get a confirmation, then a schedule moves and you get it again. Meanwhile you are holding a crew and a location against a date that is not truly locked until the morning it happens. One interview day sits on top of weeks of that. Build it into the schedule as real work with a real owner, because if you treat outreach as an administrative task squeezed between shoot days, the calendar will simply not fill. A practical rule from this production. Never book a crew and a location off a verbal yes. Wait for a written confirmation with a date and a call time, and re confirm it the week of. Cancelling a crew costs money. Cancelling a subject costs you the subject, because the second ask is always harder than the first. ## Scout the room before you promise the shot The people in this series were spread across the country, so we went to them. Every city meant scouting first, walking the space, working out where a camera could live and what the room was going to sound like once it was full of gear and people. Sound is what kills documentary locations, not light. A room with a hard ceiling, a busy street outside, or an air handler you cannot switch off will fight you for the whole day, and no amount of grading fixes it later. Stand in the room, be quiet for sixty seconds, and listen. That minute has saved us more days than any piece of equipment. Then the set has to be dressed. It has to be visually interesting for two hours and comfortable for the person sitting in it, and both of those have to be true inside whatever window the location will give you. Some of the interviews were shot on sets we built from the ground up in our [Los Angeles studio](https://c-istudios.com/studio-rentals/), which let us design the room around the conversation instead of working around what a venue would let us move. Across the production it ran as a balance of the two. ![Set built in the C&I Los Angeles studio for a documentary interview](https://c-istudios.com/wp-content/uploads/2026/08/fbt-la-studio-set-build.jpg) ## Write twelve scripts, not one We conducted twelve interviews, each across a full production day. The questions carried the same sentiment on purpose, because the series had to stay on one theme. Everything else changed. Every person got their own script, and we studied each of them before they walked in. What they had built. Where their story met the money. What they were actually in a position to answer, and what they would only be guessing at. This was never a copy paste scenario, and it would have shown on camera if we had run it like one. The tell is easy to spot in a finished film. When every subject answers the same six questions, the cut turns into a survey, and a survey has no shape. When each person is asked the thing only they can answer, the same theme comes back twelve different ways and the edit has somewhere to go. Prep also buys you permission. People can hear whether you have done the reading in the first two minutes, and what they decide about you in those two minutes sets the ceiling for everything after it. ## The interview day, and why nobody gets it on the first take The goal on an interview day is to keep the person comfortable enough that they open up in front of the camera. Somebody who feels stuck on a stage gives you a performance. We wanted the opposite, which meant the room, the chair, the light and the number of people standing around all had to work toward the same thing. Coverage scales to the conversation. A straightforward sit down runs two cameras, a wide and a tight, with a dedicated sound mixer. The largest setup on this production ran five cameras and a separate audio recorder at the same time, and came back as two full drives from one sitting. That is a lot of gear for one person in a chair, and it is necessary for the same reason. After traveling, coordinating schedules, hauling gear and setting the scene, you get one sitting. Asking somebody to go back and repeat the thing they finally said is rarely an option, and if a camera missed it, it is gone. Over prepare when shooting time is limited. Cover every angle, pay attention, and make the most of the window you have. ![Camera operator on the stage during a documentary interview day](https://c-istudios.com/wp-content/uploads/2026/08/fbt-interview-day-stage.webp) ## Data management is a production department, not an afterthought Close to 23 terabytes of RED raw across nineteen drives is not a filing problem, it is a production department. On every shoot day a DIT station backed up media as it came off the cards, and the naming and the redundancy were decided before the first offload, not after. The rule we hold to is simple. Footage exists on two drives before a card is formatted, and a card is never formatted on set if there is any way to avoid it. Cards are cheap next to a day you cannot reshoot. Label by subject and date at the moment of offload, because a folder called DAY 3 CAM B means nothing eighteen months later when you are looking for one line somebody said. Three years is long enough for drives to fail, for a naming convention to drift, and for the person who set it up to move on to another project. Write the convention down. Keep it boring. ![DIT station backing up documentary footage on set](https://c-istudios.com/wp-content/uploads/2026/08/fbt-dit-station.jpg) ## Archival is a second production running in parallel Most documentaries need material nobody on the crew shot. On this one that meant historical photographs and footage, and the research ran alongside production rather than waiting for it. Public domain is where a documentary budget survives. We cleared material on Tulsa in 1921, the Freedman’s Bank and the Great Migration, sourced from public collections rather than licensed libraries. The [Library of Congress](https://www.loc.gov/) is the first stop for American archival work and most of what it holds is free to use, though you still have to verify each item rather than assume the whole collection is clear. Track provenance for every asset as you go. Where it came from, what its status is, and the link that proves it. A delivery or a festival will ask, and reconstructing that list at the end from memory is miserable. If something is not clearly in the public domain, either license it properly or work out whether your use is defensible, and the [United States Copyright Office fair use index](https://www.copyright.gov/fair-use/) is a better starting point than an opinion in a forum. ## Post starts with transcripts, not a timeline The instinct is to open an edit and start cutting. On a long documentary that is how you lose a month. Every interview on this production was transcribed and scored line by line before a frame was cut. Scoring means reading the transcript and marking what is usable, what is strong, and what is the one line that could open or close a chapter. It is slow and it feels like it is not editing. It is the highest leverage work in the whole process, because it turns fifty hours of footage into a document you can actually think with. Search a transcript and you find the moment in seconds. Scrub a timeline and you spend the afternoon. From there the shape came in stages. The first full assembly ran past three hours. That version was never going to be the film, and it was not supposed to be. It was pulled apart into eight chapters, reordered, and cut down again into a selects edit. Structure on a documentary is discovered in the edit, which is exactly why the assembly has to exist before anyone argues about the order. ## Color and sound are what make it one film Twelve interviews shot across three years, in different rooms, on different days, under different light, all have to end up looking like one film. The harder part is matching. Five cameras on a single interview, and decades of archival material cut in beside them, all have to sit in the same picture without an audience noticing the joins. The grade runs one interview at a time, node by node, until the skin tone and the room agree with each other. Then it starts again on the next one. There is no batch operation that does this, which is why color on a long documentary is measured in weeks rather than days. Sound gets the same treatment and usually gets less credit. Room tone changes between locations, and a mix that does not smooth those transitions makes a film feel assembled even when the picture is perfect. Our [post production services](https://c-istudios.com/post-production-services/) cover editing, color, sound and delivery in house, which on a project this long is less about convenience and more about the film never having to leave the building to be finished. ![Graded documentary interview on a monitor with scopes during color work](https://c-istudios.com/wp-content/uploads/2026/08/fbt-monitor-graded-interview.webp) ## The parts audiences never see are the parts that decide the film If there is one thing to take from all of this on how to produce a documentary, it is that the visible work is the smaller half. Documentary work is different from commercial work in one specific way. There is no script to fall back on and no second take of an honest answer, so the room has to be ready before anyone sits down. On this production the crew built and lit every interview set in advance, tested sound in the space, and then kept the set quiet enough that a person could talk for two hours without noticing the cameras. That preparation is invisible in the finished film and it is the thing that decides whether the film feels true. It is also why continuity of crew matters more on a documentary than on almost any other format. The team on the first shoot day was the team on the last, three years apart, and that consistency shows up in the cut in ways an audience notices without knowing why. ## Frequently asked questions ### How long does it take to produce a documentary? Longer than any schedule you write at the start. Feature documentaries are measured in years, not weeks. Fund Black Tech shot from March 2021 to 2024 and is still finishing. A short documentary or a branded documentary piece can run a few months end to end. The variable is almost never the shoot, it is access, scheduling and the length of the edit. ### How many people do you need on a documentary crew? Less than most people expect on the day, more than most people expect across the project. A sit down interview can run with a director, a director of photography and a sound mixer. Add a gaffer, a grip, a DIT and a producer and you have covered almost every documentary shoot day we have run. ### What does a documentary cost? It is driven by shoot days, travel, archival licensing and how long the edit runs. Scope it honestly at the start rather than discovering it in month eight. We wrote a separate piece on [documentary filmmaking on a budget](https://c-istudios.com/documentary-filmmaking-on-a-budget-tips-for-cost-effective-production/) that goes through where the money actually goes. ### Do you need permission to use archival footage? Usually yes, unless it is genuinely in the public domain. Verify each item individually rather than trusting a collection level claim, keep a record of where every asset came from, and clear anything you are unsure about before it is locked into a cut. ### Should you shoot interviews on location or build a set? Both work and we used both. A built set gives you control over look and sound and a consistent result across many shoot days. A real location gives you context an audience reads instantly. The deciding factor is usually the room’s sound and how much of it you are allowed to change. ### How do you keep twelve interviews feeling like one film? It comes down to three things. The same crew across the schedule, a set and lighting approach that carries between locations, and a grade that matches every interview back to a single look. Miss any one of those and the film reads as a collection of conversations. ## Bring your documentary to C&I Studios C&I Studios handles [documentary film production](https://c-istudios.com/documentary-film-production/) end to end, from the first set build through the interviews, the location days and the color work. Our studio is a 30,000 square foot facility in Los Angeles, with offices in Fort Lauderdale and New York and crew that travels, which is how a production spread across three cities and three years stays consistent. The same team also handles film and television production and broader video work when a project needs more than one format. You can watch the trailer and see how the whole apparatus described here came together on the [Fund Black Tech](https://c-istudios.com/portfolio/fund-black-tech/) project page, or look at [For Niko](https://c-istudios.com/portfolio/for-niko/) and [Community Land Trust](https://c-istudios.com/portfolio/community-land-trust/) for shorter form documentary work.
