Maestro AI Video Master
One sentence, one complete film. Describe the video you want in natural language, and the AI director automatically writes the script, creates visuals, provides voiceovers, composes music, and renders, producing a complete film with subtitles. Supports reference materials, multi-language output, and secondary creation.
Core Features
Not a fixed template, but an AI director that creates—freely arrange each video according to your intent.
One sentence to a complete film
Simply describe the theme, what to showcase, style, and audience in the prompt, and the AI automatically completes the script, visuals, voiceover, music, subtitles, and rendering, producing a publishable complete film.
Multi-language output at once
Fill in multiple languages in langs, reuse the same visuals with only new voiceovers and rendering, and get multi-language versions like Chinese, English, Japanese, etc., in one task, making overseas distribution easier.
Use your own materials
Attach reference images, videos, or audio via file_urls—let product images, logos appear, or add text and subtitles to existing materials.
Iterative secondary creation
Use action: remix / edit / extend along with ref_task_id to make incremental modifications on existing videos: change titles, swap voiceovers, adjust colors—small changes are quick, large changes require a redo.
Submit once, retrieve video asynchronously
Submit prompt to immediately return task_id, then poll /maestro/tasks to retrieve the video—polling is free. You can also pass callback_url for a callback when completed.

Frequently Asked Questions
Common questions about using the Maestro API
How does Maestro charge?›
Charged per piece, with a pre-deduction based on target duration at submission: points ≈ (60 + 1.7 × duration in seconds) × quality multiplier. For example, about $10.57 for 30 seconds, about $25.14 for 2 minutes, and about $102.83 for 10 minutes (maximum). Quality tiers: draft 0.5×, premium 2×. langs Each additional language +$0.57 (reuse footage, only additional voiceover and rendering). Polling for task results is free.
What languages are supported?›
Supports Chinese, English, Japanese, Korean, Spanish, French, German, etc. Specify using the langs array, with the first element as the primary language, and the rest will reuse footage to generate localized voiceovers and rendering.
Can I use my own images or videos?›
Yes. Pass the URLs of images, videos, or audio through file_urls, and AI will incorporate them into the final piece—such as featuring product images or logos, or adding subtitles to existing materials.
How long does it take to produce a video?›
This is an asynchronous task: after submission, task_id is returned immediately, and the final piece is usually completed within a few minutes (larger or multilingual tasks may take longer). Poll /maestro/tasks or use callback_url to get results.
Can I modify an existing video?›
Yes. Use action: remix / edit / extend along with the previous task's ref_task_id to make differential edits or extensions on the original project; small changes will be quick, while large changes will require regeneration.
