An original finished script with eight freshly generated scenes, narration and music. Every image was reviewed; three were regenerated. This first-party curated run used 95 credits. It is not a Relax latency test, an independent benchmark or a 20-minute run.

It combines the steps needed for a complete narrated video: script, scenes, visuals, voiceover, subtitles, optional music and export. Donatello builds illustrated scenes with camera movement and transitions. It is not a single continuous AI-generated live-action video. ### Can I turn my own script into a video? Yes. Choose Finished script, or start with an idea and let Donatello prepare a story. Scripts within the supported length preserve their wording; longer scripts are adapted to the 20-minute target for review before media generation. Review the narration, characters and scene prompts. Spoken timing can differ from the requested duration. ### Is Full Video Creator free, and how do credits work? Yes. Free welcome or earned credits; automatic lower-priority Relax when credits are exhausted and no surveys are available, subject to eligibility, fair use and free capacity. Optional paid credits provide faster processing. No subscription is required. You do not select a separate Relax switch: eligibility is checked automatically. In eligible Relax generations no credits are charged; each image, narration and soundtrack waits separately in the lower-priority queue. Long videos can take days. Credit-funded reservations are shown before generation, with unused credits returned. ### Does unlimited Donatello access mean unlimited Full Video projects? Yes: there is no saved-project limit or lifetime generation quota. Unlimited does not mean simultaneous or instant. The maximum requested duration is 20 minutes per video. Relax processes media sequentially with lower priority, capacity waits and fair-use safeguards. Optional credits provide faster processing. These scheduling and per-video limits are separate from commercial-use permission. ### What lengths, formats and downloads are supported? Request videos up to 20 minutes at 720p HD in 16:9, 9:16, 1:1. Actual narration timing can extend the export; the renderer allows up to 5 extra minutes to avoid cutting speech, then fits longer audio. Download the MP4 or an asset ZIP with the script, images, narration, subtitles and music when included. Relax inputs are protected while their operation is queued or running and for 72 hours after it stops. Finished exports remain downloadable for 72 hours. Save your files before retention expires. ### Can I edit the video before exporting? Yes. Review and edit the story, recurring characters and scenes; choose the narration voice, visual style, camera movement, transitions and subtitle appearance. Background music is optional. Reuse existing project assets where possible; additional or regenerated media can require more credits, shown before the action. ### Can I use the result for YouTube or commercial projects? Commercial use is permitted under Donatello's Terms, subject to input and third-party rights. Copyright, exclusivity and platform monetization approval are not guaranteed. You must have the necessary rights to scripts, references, people, voices, trademarks and other third-party material. ### Are my scripts and videos public? No. This product page is public, but projects and their files remain private to the signed-in account that created them. Opening this page does not publish a project or give another user access to it. ## Sources - [Product Facts](https://donatello.studio/product-facts) - [Pricing](https://donatello.studio/pricing) - [Terms](https://donatello.studio/terms) - [Review kit](https://donatello.studio/press/full-video-review-kit)
