What problem does it solve?

Manually creating short videos from audio files requires tedious work including transcription, subtitle syncing, scene design, animation, and video rendering, which takes hours of repetitive effort for content creators. This Skill fully automates the entire workflow to turn raw audio into a polished vertical short video in minutes.

Core Features & Use Cases

  • Automated Speech Recognition: Uses OpenAI Whisper to extract precise timestamped subtitles from audio files in multiple languages.
  • AI-Powered Content Structuring: Automatically corrects transcription errors, splits audio into logical scenes, and extracts keywords for subtitle highlighting.
  • Remotion-Based Video Rendering: Generates animated scene components matching audio content, adds synchronized highlighted subtitles, and outputs 1080x1920 MP4 videos optimized for social platforms like Douyin and Xiaohongshu.
  • Use Case: A podcaster can feed a 10-minute episode audio file to the Skill and get a fully produced short video with scene animations, keyword highlights, and synced subtitles ready to post, without any manual video editing work.
