SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Creating short video clips with AI generation requires careful prompt design, correct model control selection, and disciplined handling of references, durations, and retries—mistakes waste significant generation credits and produce unusable output. ## Core Features & Use Cases - Structured prompt authoring: Enforces a six-part prompt format covering shot design, camera intent, production detail, sound, dialogue, and ending frame, with pacing matched to clip duration. - Lane and model management: Lists signed-in video lanes and model controls (aspect ratio, resolution, duration ranges, max references) before generating, and respects the user's remembered Studio selection. - Reference-based generation: Supports image-to-video, multi-reference identity preservation, and clip continuation from a previous clip's last frame. - Use Case: A user needs a 6-second product clip for a social feed. The skill generates a still first via the image skill, uses it as a reference, picks 9:16 aspect and a duration from the model's list, generates once at draft resolution to check motion, then delivers at the highest resolution. ## Quick Start Use the video skill to generate a 6-second 9:16 clip of a coffee cup on a wooden table with steam rising, saved as clip.mp4.

FAQPage Schema
How do I generate a video clip from a text prompt?▼

Call the media tool with action 'generate', kind 'video', a structured prompt, output path, aspect, and duration. First run 'list' to see signed-in lanes and the remembered model's available controls like durations and resolutions.

How do I keep a subject consistent in an AI-generated video?▼

Generate a still image first with the image skill at the clip's aspect ratio, inspect it, then pass it as a reference to the video generation. For multiple subjects, give each reference an index and role in the prompt, with identity references first.

Can I continue or extend an existing video clip?▼

Yes, start a new job using the previous clip's last frame as the reference. Only the pose carries over—motion, trajectory, and camera movement do not transfer between clips.

What happens if no video lane is signed in?▼

The skill stops and reports that no video lane is available. It never substitutes a slideshow, GIF from stock, or placeholder when generation is not possible.

How many times should a failed video generation be retried?▼

A miss is retried once with a single changed variable and all invariants restated. A second miss is reported to the user rather than attempted again, since video generation costs far more credit than stills.

What aspect ratio and duration should I choose for a video clip?▼

Choose aspect from the destination: 9:16 for feeds or stories, 16:9 for embeds or presentations, 1:1 for tiles. Pick duration from the model's listed range based on pacing: 1-4 seconds for one action, up to 11-15 seconds for a three-beat arc.
