What you can create with Documentary

Donatello assembles a checked script into a narrated sequence with documentary-looking AI illustrations, subtitles and optional music. You supply and verify the facts: the Documentary preset controls visual direction, not research or fact-checking.

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.

A starting brief you can adapt

Create a 60–90 second illustrated explainer from my fact-checked narration. Audience: curious adults. Use observational-looking scenes, restrained camera movement and legible captions. Keep factual wording unchanged. Label generated reconstructions. Avoid invented quotations, dates, witnesses and statistics.

An example brief, not the prompt used to generate the recorded demo. Replace the subject and supply your own checked narration. Opening the editor does not start or charge for a generation.

When this workflow fits

Educational explainers, process walkthroughs and clearly labelled reconstructions. Use original research and reliable sources for every factual claim; this editor does not retrieve archive footage or verify evidence. The standard workflow composes generated still images with camera moves and transitions; it is not a promise of continuous character action.

01 / Reviewable workflow

Prepare a sourced script

Keep a separate source list for names, dates and numerical claims. Paste narration you have checked rather than asking the visual preset to establish the facts. A coherent 60–90 second sequence is a useful first review, not a mandatory length.

02 / Reviewable workflow

Separate evidence from illustration

Use the Documentary preset for a grounded visual treatment. Generated scenes can explain an idea but are not photographs of an event. State where a visual is a reconstruction and avoid depicting real people doing unsupported things.

03 / Reviewable workflow

Review scenes against the narration

Check locations, equipment, period details and causal sequences. Remove a persuasive-looking image if it implies more than the sources establish. Voice, pacing and optional music remain separate editorial choices.

04 / Reviewable workflow

Export with publication context

Review the whole MP4, including captions and audio. Add your source list and reconstruction disclosure where you publish. Commercial-use permission under the Terms does not remove privacy, trademark, copyright or accuracy responsibilities.

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 and square scenes are not supported by scene animation. Both public animation 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 initial attempt was discarded after an unwanted human reference. The storyboard and narration were corrected; fourteen images and one animation were regenerated. This editorial re-export uses Donatello camera, animation and transition filters with revised roof shots, regrouped captions and the original AAC mix. The run record preserves the original export hash and all interventions.

A curated example, not an unattended benchmark. Timing includes review and retries. Most scenes are still images with camera movement; ten use short AI clips slowed to narration. Continuity and estimated caption timing can vary. Not continuous animation, a 20-minute test or a Relax latency measurement. Results vary between generations.

Read the exact narration in this example

The summer sun hangs relentless above the horizon, bleaching the limestone terraces until they shimmer like bone. At the heart of the island, the circular stone cistern sits entirely hollow, a deep, thirsty throat waiting for a drink that never comes. Heat radiates from the parched earth of the dormant garden beds, causing the soil to fracture into a complex network of spiderweb cracks, reflecting the stillness of a world caught in a long, sun-drenched pause. A sudden, dry breeze sweeps across the terrace, carrying with it the fine, microscopic grit of the island. This dust dances in the heat haze before settling into the deep, weathered crevices of the masonry. These ancient stones, once carefully placed to guide life-giving water, now remain clogged with the debris of a season long forgotten, their intricate paths obscured by the heavy, settling weight of the island’s stillness and the persistent, golden glare. As the sun finally dips below the sea, the light shifts from gold to a bruised, twilight violet. The lighthouse, a solitary white finger against the darkening sky, bears a copper roof that has turned a deep, oxidized green over the years. With the departure of the sun, the metal begins to lose its stored heat, cooling rapidly in the evening air, though it remains tight and sealed against the cooling, dry atmosphere of the night. High above the garden, a trailing vine shifts in the cooling breeze, its weight pressing against a loose stone tile resting near the roof's edge. The tile nudges just enough to clear a small opening, a narrow gateway that had been blocked by shifting sediment. It is a tiny, mechanical adjustment, a minute shift in the geometry of the architecture that creates a potential path for water, should the clouds ever choose to break their long silence. The relief is short-lived, for a heavy, desiccated branch from a nearby shrub snaps under the pressure of the wind. It tumbles downward with a dry clatter, landing perfectly within the primary stone artery that winds toward the cistern. The branch wedges itself firmly against the rough limestone walls, creating a stubborn, impenetrable dam of organic debris that seals the channel completely, ensuring that any future flow will be diverted away from the garden beds. The wind begins to veer, carrying a sharp, salt-heavy scent from the distant, churning sea. A cooler, moist draft presses against the island, signaling a change in the atmosphere that the land seems to recognize. The limestone, long brittle and pale, begins to absorb the rising humidity, its surface darkening slightly as the moisture clings to the stone, though the physical obstruction in the channel remains fixed, a silent sentinel blocking the way. A gust, more insistent than the others, catches the end of the dry branch, rocking it back and forth within the narrow stone artery. The leverage of the wind, combined with the softening of the mortar around the base, finally dislodges the wood. The branch settles against the rim of the stone channel. Beneath it, the narrow groove is open again. What had been a sealed passage now has room for the first water to slip through, whenever the sky is ready to let it fall. On the horizon, the sea line vanishes beneath a wall of bruised, heavy clouds that gather with quiet, purposeful weight. The horizon thickens, blotting out the stars and dimming the island’s stark outlines. The light across the limestone terraces shifts to a soft, expectant grey, a muted palette that emphasizes the texture of the stone and the sudden, atmospheric tension that hangs in the air, waiting for the first movement of the coming storm. A single, heavy raindrop strikes the copper roof of the lighthouse with a sharp, resonant ring that echoes across the silent terraces. It is a lonely sound, followed by a moment of complete stillness. Then, a dark, wet streak spreads across the weathered metal, marking the path where the water first touches the surface. The island holds its breath, the stone drinking in the initial contact, while the sky prepares to deepen its rhythmic, falling cadence. The rain begins to fall in earnest, the pace quickening until a thin, shimmering sheet of water coats the copper roof. The surface, once dull and dry, now reflects the grey sky, turning into a liquid mirror. The water gathers speed, racing toward the edge of the lighthouse, where it begins to spill over in a continuous, silver curtain, falling directly into the waiting gutter system that has been prepared by the shifting winds and the changing season. The gutter catches the runoff, funneling the volume into the primary stone channel that has been cleared of its blockages. A trickle of water enters the first section of the masonry, its progress slow as it navigates the centuries-old curves. It moves with a tentative, exploratory energy, washing over the limestone, which darkens instantly as it is reclaimed by the cool, liquid touch, the thirsty stone pulling the water into its microscopic, porous depths. The force of the mounting rain increases, and the water flows with newfound momentum, acting like a scouring brush against the channel floor. It pushes the residual silt aside, carving a clear, deep groove through the accumulation of years. The stream begins to hum as it gains speed, winding its way down the slope of the island, turning the dry, forgotten artery into a vibrant, flowing vein that pulses with the urgency of the storm’s steady, rhythmic downpour. The water reaches the edge of the first terrace, spilling over the limestone step in a graceful, crystalline cascade. It splashes into the lower channel, creating a series of small, rhythmic bubbles that travel along the path. The second terrace, which has been dry for months, begins to fill with clear, cool water. The channel turns into a glistening ribbon of silver, snaking through the terraces as the island begins to reclaim its capacity to hold the rain. Following the natural slope of the land, the water arrives at the final junction, where a stone gate directs the flow toward the cistern. The water hits the threshold, swirling briefly before pouring into the dark, circular neck of the stone reservoir. It is a moment of culmination, the end of a long, winding journey from the lighthouse roof to the center of the island, where the water begins to disappear into the depths of the waiting, empty vessel. The first splashes hit the bottom of the deep stone cistern, the sound echoing upward, hollow and sharp at first, then softening as the volume grows. A small, dark puddle forms at the base, widening with every passing second. The water is clear, reflecting the dim light from above, and as it pools, it transforms the dry, dusty interior of the reservoir into a shimmering, dark sanctuary, a hidden reserve of life tucked deep within the earth’s cool, protective limestone belly. The downpour intensifies, the sound of the rain filling the air with a steady, hypnotic roar. The trickle has become a vigorous, rhythmic flow, pouring into the cistern with relentless consistency. The water level begins to rise visibly, creeping up the ancient, carved sides of the reservoir. As it climbs, it washes away the dust of the long summer, creating a rising tide of clarity that illuminates the craftsmanship of the stone, reclaiming the cistern’s purpose as a vessel of abundance. The cistern reaches its capacity, and the water, having nowhere else to go, begins to spill over the stone rim. It flows into the irrigation furrows that branch out into the garden beds, a network of channels that have been waiting for this exact moment. The dry, cracked soil of the garden begins to drink the water, the earth darkening as the moisture saturates the parched ground, turning the dust into a rich, welcoming mud, ready to be transformed by the storm. The water seeps deep into the limestone foundation, softening the earth and reaching the roots of the dormant flora. The garden undergoes a quiet, profound change, shifting from a dusty, brittle plot into a damp, dark loam that smells of ozone and minerals. The moisture penetrates the lower layers, feeding the hidden life beneath the surface, as the island absorbs the storm’s generosity, the stone terraces holding the weight of the water in a state of quiet, saturated, and patient grace. The rain ceases as abruptly as it began, leaving the island in a state of sudden, ringing silence. The clouds begin to break, and the air is clear, washed clean by the storm. The channels are now still, filled to the brim with the precious reserves of the night’s work. The island glistens, every stone and leaf holding a droplet, the entire landscape held in a moment of suspended, glistening peace, waiting for the return of the sun to begin the next chapter. Warm sunlight breaks through the retreating clouds, striking the saturated earth and the limestone terraces with a gentle, golden light. The warmth pulls at the damp soil, and over the following days, the dormant seeds hidden within the loam begin to stir. Green shoots emerge across the terrace, tiny, vibrant markers of life that push through the wet surface, signaling the successful restoration of the island’s cycle and the arrival of a new, verdant season of growth and quiet, flourishing renewal. The lighthouse stands guard over a lush, vibrant green terrace, its white walls bright against the blue sea. The cistern is full, its surface a perfect, still mirror reflecting the bright, wide sky above. The island rests in a state of balance, its channels resting, its garden thriving, ready to sustain its life through the days to come, a sanctuary of stone and water perfectly attuned to the slow, patient rhythm of the seasons.

Questions about this style

Does Donatello research or fact-check my documentary?

No. This workflow prepares and assembles a narrated video. You are responsible for selecting reliable sources, checking the script and reviewing generated illustrations.

Does it supply real archive footage?

No. The preset makes documentary-looking generated imagery. Do not present those illustrations or optional animated clips as genuine archival evidence.

How is Documentary different from Cinematic?

Documentary is for grounded explanatory visuals with explicit factual review. Cinematic is for directed lighting and dramatic composition, particularly fictional stories. Both use the same editor and neither visual preset proves that an event occurred.
