Customization

Customization

You can override the default prompts at the project level and, where applicable, at the work level or per request.

Project level

When creating or editing a project (UI or API):

Field	Effect
systemPrompt	Replaces the default scenario system prompt for all works in this project.
analyzerPrompt	Replaces the default analyzer prompt for reference video analysis.
imageSystemPrompt	Default extra instruction prepended to every image prompt (used if work/request doesn’t override).
videoSystemPrompt	Default extra instruction prepended to every video prompt.
knowledge	Extra context appended for the LLM in scenario generation.
styleGuide	Tone, colors, tempo, camera, brand voice, must_include, must_avoid — applied in scenario (as “Project Style Guide”), image prefix, and video prefix.

New projects are initialized with the shared defaults (DEFAULT_SCENARIO_SYSTEM_PROMPT, DEFAULT_ANALYZER_PROMPT, DEFAULT_IMAGE_INSTRUCTION, DEFAULT_VIDEO_INSTRUCTION). You can then edit them in project settings.

Work level

When creating or editing a work (UI or API):

• systemPrompt — Overrides the project’s scenario system prompt for this work.
• imageSystemPrompt — Overrides the project’s image instruction for this work.
• videoSystemPrompt — Overrides the project’s video instruction for this work.
• analyzerPrompt — Overrides the project’s analyzer prompt for this work.

If a work leaves these empty, the project (or shared) defaults are used.

Per request (API)

• Scenario — Request body can send systemPrompt, knowledge, styleGuide in addition to intent and analysis. These override or extend what’s stored on the project/work when the API uses them.
• Analyze — Request can send a custom analyzerPrompt.
• Generate image / video — Request can send image_instruction, video_instruction, styleGuide. If provided, they are used instead of work/project settings for that call.

Summary

1. Defaults — In shared (TypeScript); used when no project/work override exists.
2. Project — Set once; applies to all works unless overridden.
3. Work — Override per video pipeline.
4. Request — Override per API call when the endpoint supports it.
