AI Video Generator

Turn a document into a narrated video.

Upload a PDF, article, or note. VocalVia writes a short narration, reads it with a natural AI voice, pairs each scene with an AI-generated image, and renders an MP4 you can share.

What you get

Not a slideshow. A narrated video, scripted from your source.

Most AI video tools stitch stock clips. VocalVia plans a narration from your document first, then builds scenes around it — so the video stays on-message and editable before you render.

AI narration from your document

Upload a PDF, article, or note. VocalVia writes a short narration script and reads it with a natural neural voice — no recording booth needed.

Scene visuals, auto-generated

Each narration scene is paired with an AI-generated image, with shared visual guidance available when you want a more consistent look.

One studio, four scenarios

Training Video, Product Explainer, Knowledge Explainer, or a Custom format — pick the scenario that fits your source.

Reuse the full voice library

Choose any catalog voice or a cloned voice for narration, with the same picker used across the TTS and podcast studios.

Edit before you render

Review the narration and scenes first. Tighten the script and swap visuals before spending render credits.

Download-ready MP4

Render a 1280×720 MP4 with optional subtitles, ready to share, embed, or upload where your audience is.

Frequently asked questions

What is an AI video generator?

An AI video generator turns a source document into a narrated video. VocalVia writes a short narration script from your source, reads it with a neural voice, pairs each scene with an AI-generated image, and renders an MP4.

What kind of source can I use?

Paste text or upload a PDF, article, note, or report. Very long files are summarized to a narration-friendly length before the script and scenes are planned.

How long does a video take to generate?

Planning and narration scripts take under a minute each. Scene image generation, audio synthesis, and the final FFmpeg render typically take a few minutes for a short video.

Can I edit before rendering?

Yes. The narration segments and scene visuals are fully editable before you spend render credits. You can change the script, swap a narrator voice, and refine scene images.

What scenarios does Video Studio support?

Training Video for onboarding and SOPs, Product Explainer for demos and launches, Knowledge Explainer for education and research, and a Custom format for anything else.

Can I control the finished video?

Yes. Review and edit every narration segment, choose the narrator, replace scene images, and decide whether to include subtitles before the final render.
