Start with a pre-generation action-load checklist
- State the shot purpose: what change must the audience understand by the end?
- Copy the accepted duration, complete dialogue, and accepted ending without rewriting them.
- Record the full start: actors, objects, hands, positions, distance, obstacles, existing sound, and current knowledge.
- Mark the indispensable trigger, decisive action, necessary reaction, and landing.
- Mark decorative gestures, extra environmental activity, repeated reactions, and prop business with no story consequence.
- Mark dependencies: approach before contact, contact before force, release before another hand receives an object.
- Check dialogue, sequential actions, pauses, and the ending reaction against the same boundary.
Action load depends on the specific shot's distance, contact complexity, dialogue, performance, and camera waits. Four verbs may describe one clear continuous action, while two may conceal a room crossing and a complex handoff. The practical question is whether the story change can occur clearly within the accepted duration.
Protect the action spine with a two-column worksheet
This author-designed worksheet supports pre-generation review; native short-drama-video-prompts documents do not require this structure.
| Review field | What to record for the current shot |
|---|---|
| Purpose and boundary | Shot duty, accepted duration, complete dialogue, start, and accepted ending. |
| Indispensable trigger | The visible or audible event already established by the script or storyboard that starts the change. |
| Decisive action | Which actor acts on which object, in what direction, and how that action changes story state. |
| Necessary reaction | Who receives the change and which gaze, stopped action, distance, or vocal shift is readable at the current framing. |
| Landing | How actors, objects, positions, system state, and sound settle into a state the next shot can inherit. |
| Removable decoration | Gestures, travel, and prop business that add bustle, repeat information, or create new dependencies. |
| Sequential dependencies | Actions that must occur in order and actions that can naturally overlap dialogue or continuing ambience. |
| Boundary request | The specific reason to ask the storyboard owner for a split, extension, or reblock when simplification remains infeasible. |
Remove decoration first. Then combine naturally continuous actions without deleting causal nodes and choose one primary focus of attention. Preserve complete dialogue and the accepted ending.
Original paper example: a kiln alarm in a ceramics classroom
The Kiln Alarm is an original paper example created for this article. It has not been submitted for generation and provides no measured model duration or rendered result. For this fictional shot, the project has accepted an eight-second boundary, the line “Don't open it. Cut the power first,” and an explicit ending: Su releases the lowered isolator and holds his hand at his side; Ji remains behind the worktable; neither touches the kiln door; the warning lamp is dark and the buzzer has stopped. Eight seconds is an authored boundary for this example; model capacity and generation success still require separate evidence.
Complete starting state: student Su Wei stands to the right of the kiln, his right hand one palm-width from the door latch without touching it. The wall isolator is just beyond his right shoulder and currently points up. The kiln door is closed, a red warning lamp is lit, and a buzzer sounds intermittently. Instructor Ji Cen stands behind the worktable on the left with empty hands. A glazed bowl remains at the center of the table, and heat-resistant gloves hang from a wall hook to the kiln's left. Su believes the alarm means he should open the door to inspect it; Ji knows the power must be isolated first.
The overloaded version asks Ji to put down a brush, wipe the bowl rim, circle the worktable, take the gloves, walk to the kiln, grab Su, deliver the complete line, open a cabinet for a logbook, and point at the temperature display. At the same time, Su touches the latch, stops, steps back, lowers the isolator, and looks at Ji before they finish on opposite sides of the kiln, an unaccepted decorative ending. This version invents a brush absent from the start, adds repeated cross-room travel, creates dependencies around the gloves and logbook, and makes the intervention, dialogue, power isolation, and ending reaction compete inside one boundary.
| Keep or remove | Revised causality |
|---|---|
| Trigger: warning lamp and buzzer | Keep. Su continues moving his right hand toward the latch. |
| Decisive action: the instructor stops the opening | Keep. Ji stays behind the table and delivers the complete line; she does not cross the room to grab Su. |
| Necessary reaction: the student receives the instruction | Keep. Su stops before touching the latch and redirects his right hand to the isolator beside his shoulder. |
| State change: isolate power first | Keep. Su lowers the switch; the warning lamp goes dark and the kiln door remains closed. |
| Landing | Keep. Su releases the switch and holds his hand at his side while Ji watches him from behind the table. Neither touches the kiln door, and the buzzer has stopped. |
| Wiping the bowl, taking gloves, fetching a logbook, crossing to the kiln, and pointing at the display | Remove. They do not accomplish the purpose of stopping the opening and isolating power, and they add travel, holding, and contact dependencies. |
Every revised position and state has a source. Su redirects from the nearby latch to the same-side isolator. Ji remains behind the worktable. The bowl and gloves stay where they began. The kiln door remains closed throughout. The warning lamp and buzzer stop because Su lowers the established isolator. This paper causality check supports continuing into prompt writing; it does not claim that any model has generated the shot successfully.
Request an upstream boundary change when simplification is insufficient
Some actions carry genuine story duties and cannot be solved by deleting decoration. An accepted scene may require a person to cross from the far side of a room, unlock and hand over an object, deliver protected dialogue, and leave the receiver a readable reaction. Starting distance and contact order make those events sequential. The video-prompt stage should then state evidence, impact, required revision, and ownership.
| Revision-request field | What to record |
|---|---|
| Evidence | Accepted duration, complete dialogue, starting distance, obstacles, necessary contact order, and accepted ending. |
| Impact | Name the key action, reaction, or landing that cannot complete clearly inside the current boundary; “too many actions” is insufficient. |
| Required fix | Ask for two authored shots, a longer current shot, or reblocked people and objects at an executable start. |
| Preserved facts | Name the dialogue, trigger, character choice, object ownership, and ending state that remain fixed. |
| Owner | Video prompts may remove decoration; the storyboard owner decides a split, extension, or reblock; the script owner decides any dialogue or story change. |
For a split, choose a visible state closure so the first shot's ending becomes a credible start for the second. For an extension, preserve the causal order of action and reaction. For a reblock, update the starting positions and object relationships in the storyboard; the prompt stage does not move people silently.
Choose the smallest repair for the source of overload
| Source of overload | Smallest repair |
|---|---|
| Several characters perform large independent actions while the shot carries one change | Choose one primary focus and retain only reactions needed to understand the change. |
| Decorative gestures and environmental activity keep accumulating | Remove activity with no story consequence so the trigger, decisive action, and landing remain clear. |
| The same hands or body receive incompatible tasks | State the release, hand change, contact, and force order; revise the blocking boundary if the conflict remains. |
| A person must cross distance and perform several object operations | Judge from the start, obstacles, and contact chain; request a reblock, extension, or split. |
| Dialogue, action, and ending reaction must all occur sequentially | Preserve complete dialogue and the ending, remove decoration, and request a new boundary if capacity remains insufficient. |
| The ending merely says “finally arrives” | State who completes the last action, where the object lands, who reacts, and how sound and bodies settle. |
| “At the same time” compresses dependent events | Overlap only naturally compatible speech, slow gaze, or continuing ambience; restore causal order elsewhere. |
This method reviews content and boundaries before generation. When a generated video already contains deformation, omissions, or repetition, route the observed result through the appropriate rewrite, reroll, edit, or reshoot decision.
FAQ
How many actions can one AI-video shot contain?
There is no universal verb limit. Distance, contact order, dialogue, pauses, performance intensity, camera waits, and the ending reaction jointly determine load. Review the current shot from its start, purpose, accepted duration, and ending.
Can I cut dialogue first when the shot is overloaded?
The video-prompt stage preserves accepted dialogue in full. Remove actions with no story function and simplify attention first. If the boundary remains infeasible, ask the storyboard owner to split, extend, or reblock it. Return any dialogue rewrite to the script owner.
Do it with the skill
Use $short-drama-video-prompts to review this shot's action load before generation. Read its purpose, accepted duration, complete dialogue, start, and ending. Identify the indispensable trigger, decisive action, necessary reaction, and landing; remove decorative action and unnecessary dependencies; and preserve explicit contact order. If the shot still cannot complete clearly, write a split, extension, or reblock request to the storyboard owner while preserving accepted dialogue and the ending. Do not use a fixed verb count or universal timing capacity.
