How it works

You pick the topic. ClipNova makes the upload.

Every step below runs inside one generation. Here is one project, a 5 minute deep ocean documentary for a YouTube channel, followed from the first line of text to the exported files.

    Your idea

    Start from a topic, a brief or your own script

    Type what the video is about and who it is for. One sentence is enough. Already have a script? Paste it or upload it as a PDF or Word file and ClipNova follows it line by line. Set the length yourself, up to 5 minutes, or let Auto size it to the narration.

    Script

    The narration is written for your runtime

    From your idea, ClipNova writes a natural voiceover script timed to the length of the video, then plans what each scene shows under it. You never stare at a blank document before a recording session again.

    Scenes

    Every scene is generated, no stock footage

    Each beat is rendered as AI video in the style you choose, from photorealistic and cinematic to anime, claymation or watercolor, with one consistent look from the intro to the outro. Nothing is filmed, nothing is borrowed from a stock library.

    Voiceover and music

    A narrator in 18 languages, your music underneath

    Pick a natural AI voice and the language it speaks, or upload your own recording instead. Add a music track by file or link, set its volume under the voice and ClipNova mixes everything into the cut.

    Captions

    Captions highlighted word by word

    Subtitles are generated from the voiceover and burned in, with the spoken word highlighted as the narrator says it. Pick a caption style once and it holds for the whole video, so viewers who watch muted still follow along.

    Export

    A finished file, ready for YouTube

    Scenes, voice, music and captions come back as one MP4 in 16:9 for a regular upload or 9:16 for Shorts, up to 1080p and without a watermark. Want to tighten it? Open it in the ClipNova Studio to trim, split or reorder scenes and rewrite the narration.

Long form and Shorts

One tool for the whole channel, both sides of YouTube.

16:9

Long form videos in 16:9

Explainers, documentaries, top lists and story videos of up to 5 minutes per render, narrated and captioned, in the horizontal format YouTube recommends for the home feed and search.

9:16

YouTube Shorts in 9:16

Switch the format to vertical and the same idea becomes a Short with a hook in the first seconds and big captions. Turn one long video topic into several Shorts that point viewers back to it.

YouTube automation with AI

Run a channel on a schedule without filming or editing.

YouTube automation means the work behind each upload, the script, the footage, the voice, the captions and the edit, no longer depends on you sitting in front of a camera or a timeline. A topic list becomes a publishing calendar, and a new video is a new line of text instead of a new weekend.

ClipNova handles the production side of that workflow. You keep the decisions that grow a channel: the niche, the topics, the titles and thumbnails, and the upload schedule in YouTube Studio. ClipNova turns each topic into a finished video with the same narrator, style and caption look, so the channel feels consistent from one upload to the next.

Because each video starts as text, iterating is fast. Change the hook, swap the narrator's language for a second channel, or cut a long video into Shorts, then render again.

Need more than one render's worth of runtime? See the Long Form AI Video Generator for documentaries and explainers, or the Faceless Video Generator for narrated story channels with no one on camera.

AI YouTube video generator questions.

What is an AI YouTube video generator?+

A tool that turns a topic or a script into a complete video ready to upload to YouTube. In ClipNova that means the narration script, the AI scenes, the voiceover and the captions are generated in one job, your own music can be mixed in, and you get one MP4 in 16:9 or 9:16.

How long can a YouTube video be?+

Up to 5 minutes per render. Choose the length yourself or leave it on Auto and ClipNova sizes the video to the narration. Shorts usually run 30 to 60 seconds.

Can I make YouTube Shorts too?+

Yes. Pick the 9:16 format for a vertical Short or 16:9 for a regular video. The script, scenes, voice and captions are generated the same way for both.

Does ClipNova upload or schedule videos on my channel?+

No. ClipNova produces the finished video file. You download it and upload it, or schedule it, in YouTube Studio, where you also set the title, description and thumbnail.

Which languages can the narrator speak?+

The AI voiceover is available in 18 languages, including English, Spanish, French, German, Portuguese, Hindi, Arabic, Japanese and Chinese, and captions follow the voice. You can also upload your own recording.

Can AI generated videos be monetised on YouTube?+

YouTube's Partner Program rewards original content with real value to viewers, whether or not AI helped make it. Videos built from your own topics and scripts with freshly generated footage fit that, and YouTube asks creators to disclose realistic synthetic content when they upload.
