What You Will Finish With

Provider-specific outputs become reusable assets, then combine into one reviewed video without hiding provenance.

1
Plan by capability
Break the result into image generation, narration, music, motion, and editing. Do not select providers before defining each need.
2
Inspect available models
Call creative_capabilities and choose only models currently served by READY connections.
3
Generate atomic assets
Create images, voiceover, and music as separate jobs. Wait for each result to import into Media.
4
Create motion
Use a live video generation or image-to-video capability with selected images and a campaign-derived prompt.
5
Assemble and normalize
Use hosted FFmpeg tools or local Postward Creative to concatenate, replace audio, add captions, and normalize aspect ratio.
6
Review provenance and cost
Verify every asset, provider, model, credit estimate, and license before approving the final campaign run.
