Breaking Down Stunts, SFX, and VFX in One Action Scene

Nick HartyBy Nick HartySeptember 14, 20267 min read

Quick answer

To break down stunts, SFX, and VFX, read an action scene moment by moment and ask three questions of each beat: does a performer risk injury (stunt), is something rigged to happen live in front of the camera (SFX), and will the image be created or altered in post (VFX)? Many beats need two or all three departments, so each gets an owner, a decision on practical versus digital, and a note on safety and time.

Glossary pages cover each department on its own: stunts, special effects, and visual effects. This post takes one action scene and splits it among all three, since that's where breakdowns go wrong. Moments get tagged once under whichever department the reader thought of first.

The scene

From a fictional thriller, Dry County. 1 6/8 pages, night exterior, one location.

58  EXT. HALVERSON LUMBER YARD - NIGHT                       58

    Rain. Floodlights on poles. DEPUTY ROWE (40s) crouches
    behind a forklift, revolver drawn.

    Headlights. MARCUS's (30s) pickup smashes through the
    chain-link gate, clips a stack of pallets, and skids to
    a stop sideways.

    Rowe fires. The windshield spiderwebs. Marcus bails out
    the passenger side, rolls, and runs for the loading dock.

    Rowe gives chase. Marcus scrambles up onto the dock and
    Rowe grabs his ankle. Marcus kicks free. Rowe falls
    backward off the dock, six feet onto wet gravel.

    Marcus pulls a lever. A bundle of lumber swings off the
    crane hook and crashes down between them.

    Through the settling sawdust and rain, Marcus is gone.
    Above the yard, the floodlight on the nearest pole
    sparks and dies.

Pass 1: list every beat

Read for verbs, and write each beat as its own line before assigning departments. The action paragraphs break into ten beats:

  1. Rain over the whole yard
  2. Pickup crashes through gate
  3. Pickup clips pallets, skids sideways
  4. Rowe fires revolver
  5. Windshield spiderwebs
  6. Marcus bails out, rolls, runs
  7. Ankle grab and kick on the dock
  8. Rowe falls six feet onto gravel
  9. Lumber bundle swings and crashes between them
  10. Floodlight sparks and dies

Pass 2: split each beat by department

Ten beats, and eight involve at least two departments. That table goes to the production meeting, and each blank "or" becomes a decision with a name next to it.

Pass 3: practical or digital, and who decides

Each open question gets settled by the people who'll pay for it and make it safe:

QuestionWho's in the roomWhat drives the answer
Real rain or digital rainDirector, DP, special effects supervisor, VFX supervisor, line producerNight exterior with close coverage usually wants practical rain on the actors. Wide shots can extend it digitally
Blank-firing gun or non-firing with VFX flashDirector, armorer or prop master, stunt coordinator, producerActor proximity, the production's firearms policy, and budget for VFX shots
Practical lumber drop or CGSFX, stunt coordinator, VFX, gripWhether a lightweight rig can land between performers safely and reset in reasonable time
Floodlight sparksElectric, SFX, VFXMany productions use a practical light cue and add sparks in post

Write the answer on the breakdown sheet. A "TBD" on the sheet means neither department puts it in their bid, and you find the gap when the VFX vendor's number comes in without muzzle flashes.

Safety bulletins

The Industry-Wide Labor-Management Safety Committee publishes safety bulletins, hosted by Contract Services, and its page states they may be reproduced and attached to call sheets. The committee describes them as recommended guidelines, and state, federal, or local regulations override them where they apply. For scene 58, the relevant ones from the bulletin list:

BulletinTitleScene 58 beat
No. 1Recommendations for the Use of Firearms, Blanks, and Dummy Rounds4, 5
No. 4Stunts2, 3, 6, 7, 8
No. 18Guidelines for Safe Use of Stunt Air Bags, Boxes or Other Freefall Catch Systems8
No. 23Guidelines for Working with Portable Power Distribution Systems and Other Electrical Equipment1, 10 (floodlights and rain)

If the production chose pyrotechnic sparks or an actual flame, bulletins No. 16 (pyrotechnic special effects) and No. 19 (open flame) would join the list. The 2nd AD attaches them to the call sheet, and the 1st AD runs a safety meeting before the first rehearsal.

What this does to the schedule

Scene 58 is 1 6/8 pages. On a dialogue day, that's a morning. Here, every stunt beat needs a rehearsal at walking speed, then at speed, before cameras roll. Breakaways and windshields need a full reset between takes, and the rain needs to be turned off and on around resets. Wet doubles need to be dried or changed. Night exteriors also cap your day at the hours of darkness.

So build action days from setups and resets, since the page count says little about how long scene 58 takes. Ask the stunt coordinator and SFX supervisor for their time estimates per beat and build the day from those. The pages per day guide explains why a big action page count can take several nights. Often the right answer is splitting scene 58 across two nights, the vehicle work on one and the dock fight and lumber drop on the other, possibly with a second unit handling inserts.

What this does to the budget

Each department prices its lines differently. Stunts price by performer days, coordinator days, rehearsal days, and rigging. SFX prices by crew days, rigs, and consumables like breakaways and windshields, which multiply with takes. VFX prices by shot, so its number depends on the shot list and on how many of the "or" decisions went digital. In a typical chart of accounts those land in separate accounts, and our post on VFX and music budgeting covers how to carry VFX shot counts before the edit exists.

Common misses

  • Tagging the gate crash as a vehicle and forgetting the stunt driver.
  • Listing the fall and forgetting matching wardrobe for the double.
  • Budgeting practical rain and forgetting the water truck, the pumps, and the permit for running water on a location.
  • Tagging a gunshot as a prop and not flagging the armorer or the VFX flash.
  • Leaving the lumber drop undecided until the tech scout, when the crane rental is already booked.

In Storiara, the Music & Effects module groups items under Visuals, Sound, Music, and Stunts, and you can highlight text in the script to add a Stunt, Visual FX, or Sound FX item to the scene. The breakdowns documentation has the details.

Frequently asked questions

What is the difference between SFX and VFX in a breakdown?

SFX (special effects) happen physically on set during the take: rain, fire, squibs, breakaways, wind. VFX (visual effects) are created or changed in post: set extensions, wire removal, screen replacements, digital muzzle flashes. Breakdowns mark SFX blue and track VFX separately so both departments can bid.

Who decides if a moment is a stunt?

The stunt coordinator. The breakdown's job is to flag anything that might carry risk, including implied action like a character being shoved or falling on a wet surface, and let the coordinator decide what the actor can do and what needs a double.

Can one moment be a stunt, SFX, and VFX at the same time?

Often. A performer thrown back by an explosion can involve a stunt performer on a ratchet, an SFX air mortar and debris, and VFX to remove the cable and add fire. List the moment once and give each department its own line.

Which safety bulletins apply to action scenes?

It depends on the action. The Industry-Wide Labor-Management Safety Committee's bulletins include No. 1 on firearms and blanks, No. 4 on stunts, No. 16 on pyrotechnic special effects, No. 18 on air bags and freefall catch systems, and No. 19 on open flame. They can be attached to call sheets.
