How an interactive film workflow moves from script to shooting: production unit cards
A finished script is not yet shoot-ready. A production unit card hands shared footage, route differences, prop states and open questions to named owners, with checkable evidence for release or return.
Introduction
In an interactive film workflow, shoot readiness depends on whether the receiving team can use the same materials to identify what to film, what can be shared, how branch differences appear and what remains unresolved. A finalized script is an input; the output is a production-unit package with versions, acceptance evidence and owners. Do not release the affected unit while an unresolved issue could change story causality or required images.
This article covers the interface between script and shooting preparation, not shooting order. The Silent Recording Room is an original fictional teaching example, not a real user case, tested achievement or product feature. Its cards and criteria are example designs.
1. Divide content into independently checkable units
In a recording room, investigator Xu Ning finds a recorder and can “Play the recording” or “Ask the administrator directly.” After playback she hears a cough and asks whether the administrator was there last night; asking directly leaves her knowing only that someone moved the equipment. The administrator then retrieves a key on both routes, but her knowledge differs.
“Find recorder, choose, talk, get key” does not tell the camera team how much coverage to prepare, and actors may carry post-recording suspicion into the other route. Start with five candidate units: discovery, playback, direct question, post-listening follow-up and key retrieval. Then check whether the last can actually be shared.
A production unit is a set of requirements that can state its own entry, exit and required filming content. It may contain several shots and is not a scene, route or take. Overlarge units hide differences in dialogue; overfine ones turn every gesture into separate approval and lose complete actions during handoff.
The writer supplies at least script version, relevant pages, choice conditions and next-passage continuity requirements. Production checks consistent references. Dialogue from draft 3 with route connections from draft 2 must return for version alignment, not be patched by verbal explanations on set.
2. Record requirements and proof on the unit card
Actors, location and props identify resources but not how to judge readiness once they arrive. Copy the fields below, fill one card per unit and label attachments with its ID.
| Field | Required content |
|---|---|
| Identity and source | Unit ID, revision, script version and pages |
| Applicable conditions | Incoming routes and what the character already knows |
| Entry and exit | Character positions, object states and outgoing information |
| Shared content and differences | Reusable content, separately filmed content and prohibited uses |
| Required coverage | Actions, dialogue, reactions and necessary sounds |
| Preparation evidence | Storyboards, prop references, sound plan and attachment locations |
| Open issues | Issue, impact scope, owner and closure deadline |
| Acceptance decision | Release or return, basis, confirmer and date |
Required coverage states narrative needs, such as clearly seeing Xu Ning press play herself. The director and cinematographer decide close-up or continuous medium shot. This checks omissions without making the card dictate composition.
At handoff, the writer confirms causality and information, the director expression, and camera, sound and props leads feasibility; production consolidates blockers. One person may cover several roles in a small team, but identify each confirmation rather than replace evidence with one blanket signature.
3. Complete playback, then check sharing boundaries
Fill “Rec2, revision 1”: script draft 3 page 2; viewers selected playback and Xu Ning has not heard the cough; entry, recorder stopped and right hand hovering over the button; exit, playback ended, hand withdrawn and cough known. Connect to post-listening follow-up, not direct question.
Require three things: identifiable button press, a usable reaction at the cough and a final turn toward the administrator. The sound plan uses an on-set cue for performance, replaced by the final recording in post. Set cue timing, content and recording arrangements before shooting. “Sound in post” alone leaves actors guessing when to react.
Prop attachments show button positions before and after playback. If the prepared recorder cannot hold the pressed state, withhold release. Use a suitable prop or rewrite the action as press-and-spring-back and revise the storyboard. Recheck exit conditions for either approach rather than swap a visually similar machine.
For key retrieval, a detail shot of the administrator reaching to open a drawer can be a shared candidate only without route-specific dialogue or Xu Ning’s differing reaction. Film her alert post-recording close-up separately. Define sharing with action and composition limits, not “universal ending.”
If the director wants tension in a continuous two-shot, film two complete versions instead. Sharing details or separate footage depends on whether the expression plan can conceal differences; the card records that choice as requirements.
4. Resolve open issues through shoot-readiness criteria
This example has three criteria. Narrative closure: every entry has a valid premise and exits connect to named next passages. Clear expression: required information has an image or sound plan instead of improvised critical evidence. Supported execution: owners confirm people, prop states and technical preparation, with findable attachments.
Unresolved cough identity affects Xu Ning’s question and the administrator’s reaction, so return it to writer and director. Unresolved placement after a spoken line belongs to director and sound lead. Neither earns release through “decide on set.”
Cup color can be nonblocking only if confirmed not to carry a clue, not constrained by existing adjoining footage and irrelevant to composition. Name the prop owner and latest decision time. If color identifies a suspect, the same issue becomes blocking. Judge size by impact.
A shoot-ready scene requires every planned unit to pass. If only discovery passes, release that explicit scope and keep unresolved units outside the package; partial approval is not whole-scene approval.
5. Accept preparation evidence; recheck changes
The package contains a unit index, released cards, matching script extracts, expression plans and state references, plus unreleased-unit list. The index specifies active revisions and lets anyone find attachments by ID. “Everyone read the script” does not replace this handoff.
Acceptance does not establish usable footage. After filming, separately check performance, continuity and coverage. Current evidence is unambiguous critical requirements and supported preparation, not a promised finished-film effect.
If the cough is removed just before shooting, pause Rec2 and post-listening follow-up releases, list affected dialogue, reactions and sound attachments, then revise and reconfirm. Discovery may retain its decision if it does not reference that information; unrelated content need not all be redone.
The card suits this small branching scene. Complex action, special filming conditions or more technical dependencies need additional preparation. Scheduling receives clearly scoped, version-consistent released requirements; deciding what comes first and how to group sets remains scheduling’s task.
