Pre-Production

What is pre-production?

Pre-production is the second of the five stages of film production: development, pre-production, production, post-production and distribution. Development ends when a project is financed and greenlit; pre-production starts there and ends when the camera rolls on the first day of principal photography.

In practice it is the phase where a script stops being literature and becomes logistics. Every scene is broken down into the things it needs, every thing gets a price and a date, and every picture the director imagines gets drawn, described or tested before a crew of forty people stands around waiting for it. Producers often say prep is where films are actually made; the shoot only proves whether the plan was good.

Three deliverables define a finished prep: a schedule that says what gets shot on which day, a budget that the schedule fits into, and a visual plan (lookbook, storyboards, shot lists) that tells each department what the camera will see. If any of the three is missing on day one, the production is still in prep, just paying shoot-day rates for it.

What happens in pre-production? The checklist

Order varies by project, but the dependencies don't: you can't schedule before you break down the script, and you can't lock locations before you know the schedule. A working pre-production checklist looks like this:

1. Lock the shooting script. Number the scenes. Later revisions go out on colored pages so nobody works from an old draft.
2. Script breakdown. The first AD or production manager runs a script breakdown, tagging cast, extras, props, wardrobe, vehicles, stunts, effects and locations for every scene.
3. Schedule and budget. The breakdown feeds a shooting schedule, ordered by location and cast availability rather than story order, and a production budget built on that schedule. The two are revised together until they agree.
4. Hire key crew. Director of photography, production designer, first AD, costume designer, editor. Department heads then hire their own teams.
5. Casting. Auditions, callbacks, chemistry reads, offers and deals. Casting often runs in parallel with everything else and quietly drives the schedule, because actor availability dictates which days are possible.
6. Locations. Scouting, photographing, negotiating, permits. The location manager narrows options; the director, DP and designer choose on a recce; the whole team walks the chosen filming locations again on the tech scout.
7. Design. Sets, costumes, hair and makeup, props and graphics get designed and approved against a mood board and then a lookbook.
8. Visual planning. Storyboards for anything complex, shot lists for every scene, previs for stunts and effects, camera and lens tests.
9. Rehearsals and table read. The full cast reads the script aloud; key scenes get blocked in rehearsal space or on location.
10. Legal and logistics. Insurance, contracts, clearances, travel, catering, equipment orders, unit base and parking.
11. Final production meeting. Every department head walks through the schedule day by day. Then the first call sheet goes out.

Who runs pre-production?

Prep has two tracks that must meet: the logistical track and the creative track.

Logistics belong to the producer's side. The line producer owns the budget and hires; the production manager runs the office, deals and vendors; the first assistant director owns the breakdown and the schedule and will later run the set by it. The location manager, casting director and production coordinator report into this track.

The creative track belongs to the director and the department heads. The director works through the script with the cinematographer on coverage and shot design, with the production designer on the world, and with the costume designer on the characters. Their answers become the storyboards, shot lists, set drawings and costume plots.

The tracks collide in the scheduling meeting. A director who wants a shot at sunset on a location only available in the morning finds out in prep, where it costs a conversation, instead of on the day, where it costs the scene. The first AD's job is largely to force these collisions early.

Visual pre-production: from mood board to previs

For the director and DP, prep is where the film's look is decided, not discovered. The usual chain runs from loose to exact:

• Mood board: tone, color, texture, references from films and photographs. Nothing is binding yet.
• Lookbook: the approved look, organized by character, location and act. Departments design from it.
• Storyboards and shot lists: the scene cut into setups. Boards show framing and movement; the shot list adds lens, camera support, coverage and order of shooting.
• Previs: rough 3D or animated versions of complex sequences, so stunts, effects and camera moves can be timed and costed before anyone builds a rig.

On the camera side, prep also means lens and filter tests, makeup and wardrobe tests on camera, a lighting plan per location, sun-path checks for every exterior, and a gear list the rental house can actually fill. A good tech scout ends with the gaffer and key grip knowing where the generator parks and which windows need gelling.

Hitchcock is the classic example of how far this can go: he was known for planning his films shot by shot on paper before the shoot began. Few productions need that degree of control, but every production benefits from knowing which scenes need it.

This is where FlashBoards fits: one infinite board per project, where the mood board, lookbook frames, AI-generated storyboard panels, previs clips and the director's notes sit side by side, so the DP, designer and first AD work from the same picture of the film rather than from five different folders.

How long does pre-production take?

Length scales with the number of decisions, not the number of pages. Typical ranges:

| Project | Typical prep | What dominates it | |---|---|---| | Short film, 1–3 shoot days | 2–6 weeks | Locations, casting, favors | | Music video or commercial | 1–3 weeks | Treatment approval, one or two big set pieces | | Indie feature, 18–25 days | 6–10 weeks | Casting, locations, the schedule | | Studio feature with VFX | 3–6 months or more | Set builds, previs, effects planning |

A rough rule for independent features: plan at least as many weeks of prep as the shoot has weeks, and more if you are building sets or shooting stunts. Micro-budget films are the exception that proves the rule: they have no money to fix problems on set, so they need proportionally more prep, not less.

Prep gets cut first when a schedule slips, because the start date is tied to actor availability and financing. The cost shows up later: overtime, extra days, reshoots and scenes that look improvised because they were.

Pre-production vs. post-production

Both phases happen away from the set, and both are about control, but they work on opposite material. Pre-production plans what the camera will capture; post-production shapes what the camera actually captured.

| | Pre-production | Production | Post-production | |---|---|---|---| | Works with | The script and ideas | Actors, sets, light | Footage and sound | | Key outputs | Schedule, budget, boards, shot lists | Dailies, sound files, continuity notes | Edit, VFX, grade, mix, deliverables | | Cost of a change | Low: a conversation or a redraw | Highest: the whole crew waits | Medium, and limited to what was shot |

The phases leak into each other. Editors and VFX supervisors are often hired in prep to check that the plan will cut and composite, and post schedules are drafted before the shoot. The old line "we'll fix it in post" is really an admission that something wasn't fixed in prep.

Common pre-production mistakes

• Scheduling before breaking down. A schedule without a breakdown is a guess; missed stunt rehearsals and forgotten picture vehicles show up on the day.
• Boarding everything or nothing. Board action, effects and anything with a hard cut point. For dialogue scenes a shot list and a blocking plan are usually enough, and the actors need room.
• Scouting at the wrong hour. A location seen at noon can be unusable at 4 p.m. when the sun drops behind the building opposite. Scout at the time you'll shoot.
• Locking the look without camera tests. Wardrobe that reads on a mood board can moiré, clip or vanish on the sensor.
• Treating prep as paperwork. The documents matter less than the decisions they record. If the director hasn't committed, a beautiful shot list only hides the gap.
• No buffer. Build weather cover sets and a contingency line into the budget. Prep is also where you decide what gets cut if day 12 goes wrong.

AI doesn't replace a first AD, but it compresses the slowest parts of visual prep: getting a picture into everyone's head before money is spent. Start with a gray previs frame in Nano Banana 2 Lite to test staging and lens, draw the same beat as a storyboard page in GPT Image 2.5, then have MiniMax H3 Max Turbo move the previs frame to check timing. Keep all three next to the shot list on one FlashBoards board.

Common mistakes

• Previs turns photoreal. Image models drift toward finished renders. Repeat untextured, flat gray clay shading and simple geometry, and give the hero a single solid color.
• Storyboard characters drift between panels. Put the same three identity anchors in the prompt for every page, and ask for consistent style across all panels.
• Labels and panel numbers come out garbled. Keep burned-in text to a few characters, or leave it out and write scene and shot numbers as notes next to the frame on the board.
• The camera move is vague. Without direction, height and speed, video models default to a slow push-in. State the move as you would on a shot list.
• Mistaking a clip for a schedule. An AI previs clip tests staging and rough timing; it says nothing about how long the setup takes to light and rig. Take that question to the first AD and the DP.
