What you can create with Horror

Use the Horror preset for ominous visual direction and, when developing a story from an idea, horror-tone guidance for the planner. Review the plot, images and performance separately before exporting your narrated video.

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

Original supernatural mysteries and atmospheric suspense. Unease can come from lighting, an unexplained detail and careful pacing without graphic imagery. The standard workflow composes generated still images with camera moves and transitions; it is not a promise of continuous character action.

01 / Reviewable workflow

Decide what the audience should discover

Establish a normal place, introduce one unsettling detail and let the consequences escalate. State your intended audience and limits in the brief.

02 / Reviewable workflow

Keep control of a finished script

The style is not permission to rewrite your completed narration. Supported finished scripts keep their wording; overlong scripts require an adaptation for review. Inspect the storyboard before generating images.

03 / Reviewable workflow

Review the visual threat

Check that darkness does not hide the important event and that images do not invent violence or victims absent from the narration. Choose and review the level of intensity deliberately.

04 / Reviewable workflow

Choose voice, music and rhythm separately

Horror is not an automatic sound-design package. Select an appropriate narrator and optional soundtrack, check the mix and review transitions. Do not assume the preset adds sound effects or an acted performance.

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.

Reviewed and revised for the electric flashlight, five-finger anatomy, the ticket beneath the door, chronological train arrival and dark carriage. The final scene uses a simplified clock face. Still imagery illustrates the story; it does not depict clock hands moving backwards. Caption phrases were regrouped for readability and the same images and narration were re-exported with the Donatello renderer. No new AI assets were generated; the run record preserves both export versions.

Manual review and retries are included in elapsed time; this is not an unattended speed benchmark. This 61.37-second credit-funded example does not test Relax latency, a 20-minute project, continuous character animation or lip-sync. Captions retain measured scene boundaries but are not word-level forced alignment. Automated image review, where recorded, was an editorial/admin pilot rather than proof of universal availability.

Read the exact narration in this example

At midnight, station keeper Ellis found a wet umbrella resting on the deserted platform. No train had stopped there for twenty years. From the tunnel came the slow scrape of luggage wheels. Ellis raised his torch. The beam reached only the first few sleepers before the darkness swallowed it. Inside the ticket office, the old departure clock began to move backwards. A single fresh ticket slid beneath the locked door. Ellis turned it over. On the blank paper, water spread into the shape of a hand. Five dark fingerprints appeared against the other side of the window. He backed toward the platform exit. Beyond the glass, an empty train arrived without headlights, its doors opening onto complete darkness. Ellis left the umbrella where he had found it and walked away without looking back. Behind him, the departure clock struck thirteen.

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 horror 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 horror 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 horror 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.

Does Horror change only the image style?

The code applies horror-specific visual direction and supplies horror-tone guidance when planning from an idea. The published example starts from a finished script, so it demonstrates the visual and assembly workflow, not autonomous horror writing.

Does it rewrite my finished script into horror?

No. A supported finished script is preserved. Choose an idea-based workflow if you want story development, and review the generated narration before proceeding.

Does the demo prove automatic horror voice and music?

No. Voice and optional music are separate choices, disclosed in the example. The preset is not a promise of automatic sound effects, horror acting or continuous generated action.
