What a script breakdown inventories — scenes, eighths, cast, locations, day/night — and how to run a private first pass before a coordinator locks the board.
A breakdown tags a locked or near-locked screenplay for production work: who appears, where it shoots, how long each scene runs in eighths, and which departments a scene is likely to touch. Coverage judges story and craft for development. One builds a shoot; the other evaluates a read. Mixing the two is how a writer ends up treating a cast list as a quality score.
The useful first pass is an inventory of observable structure — sluglines, cues, inherited time of day, page length — not a prediction of whether the scene will play. Software can extract that inventory from Fountain or FDX. It cannot decide that the horse in a joke must be budgeted, or that two diner sluglines are the same set.
Each scene becomes a strip: INT/EXT, location, production time, page, eighths, and the characters who appear. Those strips roll up into cast weight, location repeats, and a day/night mix. Eighths are the industry unit for scene length on a formatted page — a half-page scene is 4/8 — so coordinators can talk duration without pretending the page is a stopwatch.
CONTINUOUS, LATER, and SAME inherit the previous scene's light. That is why a diner that opens DAY and continues without a new time of day still schedules as day. Authored scene numbers (including A-pages such as 4A) should survive the pass; inventing new numbers on every export is how a board and a draft stop matching.
Renaming the same location every visit, splitting one character into three cue spellings, and burying a costly element inside a witty action line. Breakdown software and humans both read what is on the page. If the horse is a joke and the joke never names a horse, no department will pull one.
Specs do not need a colored board. They do need consistent sluglines and cues so a future coordinator is not inventing sets. Locked numbers and omitted-scene markers exist so a breakdown can survive a rewrite without renumbering the world.
Start from the structured page, not a retyped spreadsheet. Paste Fountain or open an FDX in a private browser tool, confirm CONTINUOUS inheritance and authored numbers, then treat ALL-CAPS action tokens as candidates — not a finished props list. Export CSVs for a coordinator only after you have walked the strips.
Inkwell's free script breakdown tool uses the same production ledger Plot uses for reports. Nothing is uploaded. The output is still a first pass: a 1st AD or coordinator decides what must actually be pulled, scheduled, or ignored.
Stop when the page is stable enough that a board would not be fiction. A breakdown is not a shooting schedule, a budget, or a substitute for StudioBinder, Movie Magic, or a 1st AD. If scene numbers are still floating and locations still rename themselves, keep writing — do not color a moving target.
Once numbers lock, keep the inventory attached to the same structured draft and save-point history you will export as FDX or PDF. Re-entering the script into a second tool just to tag elements is the cost this first pass is meant to shrink, not a step you should invent twice.
Usually not. Specs are for reading. Breakdown belongs to production after a script is headed toward a shoot. Write so a future breakdown would not invent chaos.
Eighths are the industry unit for scene length on a formatted page — a half-page scene is 4/8. They are a scheduling language, not a runtime guarantee. Inkwell's public first-pass tool estimates them from scene word count, the same proxy Plot's production reports use, not from a laid-out Courier page.
No. Software can inventory observable structure from Fountain or FDX. A coordinator still decides what is a real element, what is a joke, and what the board must actually carry.
Inkwell's public tool parses locally in your browser and does not upload the screenplay. That is a privacy property of this page, not a claim about every breakdown product on the web.
