Prompt to Video: AI-Generated Story Videos | RemotionAI Blog

· 5 min read · Feature

Generate complete story-style videos from a single prompt. Includes AI-generated images, script, voiceover, and synced subtitles.

Prompt to Video is RemotionAI's fully automated pipeline that transforms a single text prompt into a complete story-style video with AI-generated images, ElevenLabs voiceover, and word-by-word animated subtitles. The output is optimized for vertical social platforms (TikTok, Instagram Reels, YouTube Shorts).

The full pipeline

Here's what happens when you submit a prompt:

  1. Script generation — Claude writes a script based on your prompt, breaking it into scenes with natural pacing and narrative flow.
  2. Image generation — For each scene, AI generates a matching visual custom to your script.
  3. Voiceover — ElevenLabs generates narration that matches the script, with appropriate pacing and tone for each scene.
  4. Subtitle sync — Word-by-word animated subtitles are generated and synced to the voiceover timing.
  5. Composition — Everything is assembled into a Remotion composition with transitions, timing, and Ken Burns effects.
  6. Render — The final MP4 is rendered and ready to download.

What works well

Story mode is at its best for narrative content: educational explainers, "did you know" style social posts, product origin stories, listicles, and motivational content.

Vertical-first design

The default output is 9:16 — optimized for mobile viewing and social platforms. The text placement, font sizing, and animation pacing are all tuned for how people actually consume short-form vertical content.
