What people make with the long-form generator

Narrated stories, kids cartoon episodes and faceless documentaries are the long videos made most often on ClipNova. Here are three of our own, each made from one short prompt.

Prompt

A 4-minute narrated story: an old lighthouse keeper's last night before the light goes automatic. A storm, a fishing boat in danger, a quiet sunrise. Cinematic, 16:9, captions on.

How it works

You bring the idea. ClipNova builds the whole video.

Every step below runs inside one generation. Here is the same project, The Lighthouse Keeper's Last Night, a 4-minute narrated story, followed from the idea to the final export.

  1. An old photo of a lighthouse next to a short text prompt for The Lighthouse Keeper's Last Night, the two ways to start a long-form video in ClipNova
    — 01 —
    Your input

    Start from an image or a few lines of text

    Upload a photo, or type what the video is about, how long it should be and who it is for. One paragraph is enough. ClipNova reads the intent, sets the tone, the pacing and the target length before anything is rendered.

  2. A hand-drawn six-panel storyboard sheet planning the lighthouse story, from the storm to the keeper at sunrise
    — 02 —
    Storyboard

    ClipNova writes the storyboard

    The idea becomes a scene-by-scene plan: what each scene shows, how long it runs, the camera move and what the narrator says over it. A long video is planned like a film, in chapters and beats, not as one endless prompt.

  3. Six generated shots of the lighthouse story in a grid, each about 6 seconds long, from the lighthouse in a storm to the keeper at dawn
    — 03 —
    Scenes

    Every scene is generated to match

    Each storyboard beat gets its own start image, which is animated into a shot of about 6 seconds, with the same look, light and grade from the first shot to the last. Chapters keep their own visuals, so a 5-minute cut never feels like a loop.

  4. The old keeper climbing the lighthouse stairs with a lantern, with a narration line and an audio waveform over the scene
    — 04 —
    Voiceover

    The narration is recorded for you

    The script from the storyboard is voiced by a natural AI narrator in any of 18 languages, timed scene by scene. Pick a voice, or clone your own, and the same video can be re-voiced for another market without re-rendering the visuals.

  5. A fishing boat in a storm under the lighthouse beam, with an equalizer overlay showing the music track under the narration
    — 05 —
    Music

    Add your own background track

    Upload a music file or paste a link to one, set its volume under the narration and choose which passage of the track plays, with an optional fade-out at the end. ClipNova mixes it into the final cut. No timeline, no manual trimming.

  6. The keeper watching the storm from the lantern room window, with a synced caption bar and the current word highlighted
    — 06 —
    Captions

    Captions synced word by word

    Subtitles are transcribed from the voiceover and burned in, highlighted word by word as the narrator speaks. Choose the caption style once and it stays consistent across the whole video, so it still lands with the sound off.

  7. The lighthouse story at its final frame in a video player, the keeper at sunrise, marked as a 1080p final render in 16:9 or 9:16
    — 07 —
    Final video

    You get the finalized video

    Scenes, voice, music and captions are assembled into one file with chapters. Export 16:9 for YouTube or 9:16 for Shorts, Reels and TikTok, up to 1080p, watermark-free with full commercial rights. Change a line in the brief and re-render in minutes.

Why long-form is different

Most AI video tools stop at a clip. ClipNova delivers the video.

A text-to-video model gives you five to fifteen seconds of footage. That is a shot, not a video. A long-form AI video generator has to solve the parts around the shot: a structure that holds attention for minutes, scenes that stay consistent with each other, a narration that carries the story, music that follows it and captions that keep it watchable on mute.

ClipNova treats the whole thing as one job. The storyboard is written first, so every scene has a reason to exist and a place in the runtime. The scenes are rendered against that plan with a shared look. Voice and captions are generated from the same script and your music track is mixed in under them, which is why everything lines up without an editor. The result is a finished cut, not a folder of clips.

Because the plan is text, changing the video is editing text. Shorten a chapter, swap the narrator's language, move the call to action earlier, and re-render. Videos go up to 5 minutes per render, and longer projects can be chained with consistent characters and locations.

Long-form AI video generator questions.

What is a long-form AI video generator?+

A tool that produces a complete multi-minute video from a brief, rather than a single short clip. In ClipNova that means the storyboard, the scenes, the voiceover and the captions are all generated from your image or text, your own music track is mixed in if you add one, and everything is assembled into one finished file.

How long can the video be?+

A single render goes up to 5 minutes. Long videos are built from shots of about 6 seconds, each animated from its own start image, so a 60-second cut has around ten shots and a 5-minute video is organised in chapters. For longer projects you can chain renders with the same characters and locations.

Do I need to write the script?+

No. ClipNova writes the storyboard and the narration from your brief. If you already have a script, paste it and the tool follows it scene by scene instead.

Which languages are available for the voiceover and captions?+

The narration is available in 18 languages, and captions are transcribed from the voice, so both switch together. You can re-voice a finished video for another market without regenerating the scenes.

Can I edit the video after it is generated?+

Yes. Re-cut scenes, swap a shot, change the narrator, adjust the music or fix a caption, then re-render the variant in minutes. Because the plan is text, most edits are a change to the brief.

What formats can I export?+

16:9 for YouTube, or 9:16 for Shorts, Reels and TikTok, at up to 1080p and watermark-free. Pick the format before you render and every scene is generated for it.
