Write an original story
Describe a character, a place and a change. A clear beginning, obstacle and resolution is more useful than a list of visual effects. You can also paste finished narration and review its scene boundaries.

How it was made: script, review and run details →What you can create with 3D Cartoon
Build a narrated story around your own characters. Donatello turns your idea or finished script into a storyboard, prepares cartoon-looking images and can animate selected scenes before assembling voiceover, subtitles and music.
Input: an idea or finished script. Output: a narrated 720p MP4 with editable scenes, subtitles and optional music or short scene animation. Free access uses the same conditions as the main Full Video editor; commercial use is subject to the Terms and third-party rights.
When this workflow fits
Short fables, friendly adventures and illustrated explainers. Start with a small cast and one clear problem to solve. The standard workflow composes generated still images with camera moves and transitions; it is not a promise of continuous character action.
Create recognisable characters
Keep clothing, colours and distinguishing features specific. Check the character reference before generating scenes; it guides recurring appearances but cannot guarantee every detail.
Review action and continuity
Check that each still image matches its narration: who is present, what they hold and where they stand. Regenerate or edit a scene prompt when an important event is missing.
Choose the performance
Select a narrator, subtitle appearance and optional music. Camera moves and transitions animate the presentation of still artwork; they are not full-body character acting.
From illustrated scenes to optional motion
Optionally animate selected scenes or all eligible scenes with Fast (480p) or Quality (LTX, 1280 × 704 or 704 × 1280 source resolution) five-second silent clips, in 16:9 or 9:16. The assembled Full Video export is 720p. Motion is slowed to fit longer narration; this is not continuous character animation or lip-sync. Comic, Whiteboard and square scenes do not use these separate clips. Whiteboard instead includes progressive drawing with a hand in its export, without an extra Fast or Quality generation. Both public clip options support eligible Relax Mode with the same configured wait and lower priority as other Relax operations, without spending account credits.
The recorded example above documents its original workflow. A newly available feature does not retroactively change how an earlier demonstration was made.
Inspect the result before choosing the tool
The reviewed demo shows the output and workflow. It was made with credits, not as a test of free-queue eligibility or waiting time. Free access follows the conditions below.
Original production renderer MP4 copied unchanged; no creative post-processing outside Donatello. The product retimes the short animation clips to narration and adds captions, transitions and an ending. The poster is an extracted frame.
Curated short demonstration, not a guarantee of identical results, an unedited first attempt, continuous character acting, lip-sync, a 20-minute stress test or a Relax eligibility/waiting-time test. Animation source clips are retimed to narration by the product renderer. AI illustrations are not documentary field evidence. Audio streams decoded fully; loudness and peak levels measured. No claim of independent listening review or sample-perfect forced alignment.
Read the exact narration in this example
When fog covered the harbor, Pip waited beside his tiny lantern. Out on the water, a little boat was drifting away from its pier. The lantern glowed above the pier. A warm glimmer reached across the mist. Soon, the boat was safely home. Pip could finally let out a happy sigh. He was small. His light was small. But both had made a difference.

Access, exports and commercial use
Free welcome or earned credits; automatic lower-priority Relax when credits are insufficient and no surveys are available, subject to eligibility, fair use and free capacity. Optional paid credits provide faster processing. No subscription is required. No saved-project or lifetime generation quota. Each operation joins the normal lower-priority Relax queue. Media within the same admitted operation share its initial wait, then process sequentially with fresh capacity and daily-budget checks. Separate operations and regenerations have their own admission and wait. Completion time varies; long projects can take days.
Request up to 20 minutes at 720p in 16:9, 9:16, 1:1. A short demonstration does not validate that maximum duration. Download MP4 or project assets before their storage window expires.
Commercial use is permitted under Donatello's Terms, subject to input and third-party rights. Copyright, exclusivity and platform monetization approval are not guaranteed.

Questions about this style
Can I create cartoon story videos for free?
Yes. Donatello offers free access through welcome or earned credits. When credits are insufficient and no surveys are available, eligible operations use automatic lower-priority free processing. No subscription is required; paid credits are optional.
Can I create unlimited cartoon videos?
Yes. Donatello sets no fixed lifetime, monthly or daily number of creations for a compliant account. Free processing depends on eligibility, capacity and fair use. Per-video duration and storage limits still apply. Unlimited does not mean instant or uninterrupted processing; long projects can take days.
Can I use my cartoon videos commercially?
Yes. Donatello permits commercial use of generated videos, including eligible free outputs, under its Terms. You must have the necessary rights to your script, references, music, voices and other inputs. Copyright, exclusivity and platform monetization approval are not guaranteed.
Does Donatello add a watermark to free video exports?
Donatello does not add a visible logo, watermark or branded end card to exported videos. This applies to credit-funded and eligible free exports; buying credits is not required to remove Donatello branding. Uploaded or generated source media may contain marks. This is not a watermark-removal tool or a guarantee about invisible provenance, metadata or third-party rights. Review your export and follow the Terms.
Is this a fully animated cartoon movie?
The Smallest Lighthouse demonstrates separate short AI-generated scene animations assembled with narration, subtitles and music. It is not one continuous acted movie or a lip-sync demonstration. Its public run record identifies the clips, revisions and final export.
Can I keep a character consistent?
Use character references and repeat important visual details. Review faces, clothing and props scene by scene; visual continuity is not guaranteed.
Can I use famous cartoon characters?
The workflow works with original characters. A style preset does not grant permission to use someone else’s protected characters, logos or assets.
