Prompt Guide for Creator Flow (Image + Video)
This guide focuses on practical prompt writing for Cannon Studio’s Creator Flow pipeline. It covers opening-frame image prompts, motion-focused video prompts, and reference usage for continuity.
Core Prompt Principle
Write prompts as production instructions, not prose paragraphs. The model performs better when your prompt clearly separates composition, subject, action, and environment constraints.
Image Prompt Structure (Shot Pre-Production)
- Frame type: wide, medium, close-up, overhead, POV, etc.
- Subject: who or what is dominant in frame
- Composition: position, depth cues, lens feel, perspective
- Lighting and atmosphere: time of day, contrast, color temperature
- Material detail: texture, weather, environment specifics
Keep image prompts focused on the first frame. Do not over-describe future motion here.
Video Prompt Structure (Shot Production)
- Action: what physically changes from frame 0 onward
- Camera behavior: push-in, pan, tilt, track, lock-off
- Pacing language: subtle, gradual, sudden, controlled
- Continuity constraints: maintain setting, subject identity, and scene logic
If a shot includes entrances, turns, occlusions, or partial visibility, references are often critical.
Using References Effectively
Reference images are best used when continuity has high risk. Keep usage intentional: use them to anchor identity and environment, not to replace prompt clarity.
- Character references: maintain identity under motion and partial visibility
- Location references: preserve environment continuity during camera movement
- Start frame references: keep generated video aligned with the opening composition
Prompt Quality Checklist
- Clear subject priority: primary subject is obvious
- Visual coherence: lighting and environment do not contradict each other
- Action plausibility: movement is physically reasonable for the shot length
- No ambiguity: avoid vague terms like “cool” or “nice” without specifics
- Continuity intent is explicit when needed
Common Prompt Failure Modes
Failure: too many competing actions in one short shot.
Fix: simplify to one dominant action plus one secondary beat.
Failure: style drift between connected shots.
Fix: repeat key continuity descriptors and use shared references.
Failure: cinematic words without scene-specific detail.
Fix: pair style language with concrete subject/environment detail.
Pair prompt design with Creator Flow and editing guides to improve end-to-end output quality.
