Starting an interactive film workflow with an idea: define the screenwriter’s scope on one page
Before handing an idea to a screenwriter, agree on what viewers can do, which paths must work, and which issues require revision. A one-page handoff definition turns a mystery premise into a development scope that can be checked.
Introduction
Start an interactive film workflow by turning the idea into a one-page handoff definition for whoever will develop the screenplay and design its paths. Specify the promised experience, minimum required paths, medium, language, exit criteria, and out-of-scope list, together with the evidence needed for acceptance. At this point, acceptance is about whether the recipient can begin designing without guessing the boundaries of the work, rather than whether the film is enjoyable.
1. This handoff establishes only what may move into development
A common gap at the idea stage of an interactive film workflow is that “let viewers solve the mystery themselves” can suggest different works to different people. The screenwriter imagines several suspects, the director imagines two endings, and the interaction designer starts planning unrestricted evidence gathering. Each interpretation could work, but within a single commission they pull the project in different directions.
The inputs can be minimal: a one-sentence story premise, a key choice, and established production constraints. The initiator is responsible for explaining the experience they want to preserve; the recipient identifies gaps that prevent development. Together, they record the definition version and unresolved issues. The output is a one-page scope agreement, not a storyboard, budget, or complete screenplay.
The example below uses a fictional small-scale interactive mystery film, The Lost-Property Locker on a Rainy Night. An attendant discovers a letter left by a missing person, and viewers decide whether to check the storage records or question the night watchman first. The characters, paths, and acceptance records are original teaching examples. They are not a real user case, measured results, or product features, nor do they imply that DramaFork automatically performs these steps.
Here, “solve the mystery themselves” is narrowed to “choose which type of evidence to investigate first, then see how that first choice affects a witness’s cooperation.” The story can leave questions unresolved, but the two first investigative choices must produce distinguishable consequences. Viewers are not required to complete all subsequent investigations in different orders.
2. Put six boundaries on the same definition sheet
You can copy the table below directly. For each field, first state the commitment, then identify the materials that make it checkable. For anything unresolved, add a decision-maker and deadline; do not simply write “to be refined later.”
| Field | Entry for this example | What to check at acceptance |
|---|---|---|
| Promised experience | Viewers decide whether to check records or question someone first, changing how the night watchman cooperates | Each choice has a different response with an explainable cause-and-effect relationship |
| Minimum required paths | A shared opening branches into a records-first path and a questioning-first path, each reaching its own closing sequence | Both paths specify their entry, choice, consequence, and endpoint |
| Medium | Landscape live-action clips linked by text choices; playback pauses at choices to wait for a response | The next stage designs clips and connections without relying on free movement |
| Language | Chinese dialogue, Chinese subtitles, and Chinese choices | All three types of text are included in the screenplay handoff scope |
| Exit criteria | Begin screenplay development only when the definition has no critical ambiguities; pause and redefine the scope if the essential location is unavailable | Specify who decides whether to proceed, pause, or return the definition for revision |
| Out-of-scope list | No inventory, unrestricted evidence gathering, timed input, or additional language versions | The path sketch contains no implicit requirements for these features |
At the top of the page, also include “project name, definition version, initiator, recipient, date.” At the bottom, include “acceptance decision, evidence reference IDs, unresolved items, responsible person, milestone by which each unresolved item must be resolved.” A blank template only needs to retain these fields; it need not adopt this example’s filming format.
“Language” states which forms of expression this assignment covers, not which markets might be supported in the future. “Exit criteria” states when this stage ends or investment in it stops, not how a character leaves a room. Viewers’ story exits are already covered by the minimum required paths.
3. Use two paths to show that the promise can be developed
This example attaches a path-sketch file to the definition sheet. Its file identifier is “Sketch A”. The records-first path reads: discover the letter → find a conflict between the storage time and the witness’s account → confront him with the record → the night watchman admits keeping the letter for someone. The questioning-first path reads: discover the letter → first promise not to disclose a name → the night watchman voluntarily hands over the duplicate storage receipt → the attendant obtains the next address to investigate.
Neither closing sequence claims that the missing person has been found. One accomplishes “exposing what was concealed,” while the other accomplishes “obtaining a lead.” This difference fulfills the promise about first investigative choice. If both paths merely end with the night watchman giving the same address, the definition sheet must answer: what did the earlier choice actually change? If there is no answer, revisit the promised experience or rewrite the consequences.
Also write a short passage establishing what viewers know before choosing: “The records can verify the timing, but a direct challenge may put him on his guard; hearing him out first requires a temporary promise of confidentiality.” This is not final dialogue. It supplies the screenwriter with the basis for the decision. Without it, “check the records” and “question him” can easily become little more than two location buttons.
Twine is used to create interactive, nonlinear stories. For this example, a text prototype could express the paths before filming details are decided. Paper cards can also support this acceptance check; the tool does not change the questions the definition sheet must answer.
At acceptance, the screenwriter walks through both sketched paths, restating what viewers know, what decision they make, and what consequence they receive. If the questioning-first path requires prior knowledge of the storage time, but that time appears only on the other path, record the gap as “the questioning-first path lacks a source for required information” and return it for revision. A verbal explanation cannot count as a pass.
4. Tie acceptance decisions to specific materials
This stage can use three decisions. Ready for development means the six boundaries and the path sketch support one another. Limited acceptance means work may begin on portions unaffected by unresolved items. Return for revision means essential promises or constraints still conflict. Signing off signifies agreement with the current development scope only; it does not prove that the work is complete or that viewers will be satisfied.
A sample record could read: “Definition B: based on Sketch A and Choice Premise A, both story paths are ready for development. The night watchman’s name remains undecided; the screenwriter will supply it before the dialogue draft.” An undecided name does not prevent cause-and-effect design, so the decision remains “ready for development.” If the unresolved issue is whether the lost-property locker location can be used, and the central clue must be shown through an object inside the locker, the decision cannot be “ready for development.” Nor can “limited acceptance” authorize the entire screenplay.
Acceptance evidence must, at a minimum, identify where the supporting material is and explain which promise it supports. “Everyone understands” cannot help someone who joins later trace the agreed scope. A one-page definition and two short paths, by contrast, can expose differences in understanding.
New requirements must also be recorded in the original fields. A request for English dubbing, for example, should reopen both the language scope and responsibility for audio delivery. A countdown should reopen the medium rules and the choice premise. The person proposing the change records the reason, the recipient assesses its impact, and a new version follows. This prevents additional work from being hidden in “just add it while you’re there.”
5. Decide which promise to preserve when reducing scope
If production can support only one shared closing sequence, the two paths can merge before it while retaining the witness’s different attitudes and the different sources of the clues. Revise the promised experience from “the first investigative choice produces two distinguishable consequences” to “the first investigative choice changes the cooperation process and the source of the clues,” and revise the production scope from “two closing sequences” to “one shared closing sequence.” The reduction is in the number of closing sequences. Do not misrepresent the earlier promise of “different consequences” as a promise of “different endings.” The initiator and recipient should jointly record in the definition whether they accept this reduction.
If even differences in the process cannot be produced, a single-path concept film can be delivered first to discuss atmosphere and performance, with an explicit statement that it does not yet validate the interactive promise. Another option is to retain the text prototype and postpone live-action filming. This suits a story whose cause-and-effect relationships are not yet stable; it must not be presented as a finished film.
The definition sheet also has clear limits: it cannot replace location confirmation, assessment of whether shots are feasible, or later viewing feedback. It gives the idea a mutually accepted starting point as it enters screenplay development. When the scope does not hold up, it also makes clear which item needs revision, instead of leaving the screenwriter to keep guessing.
