歌詞から文字PVを自動で組み立てるブラウザアプリ

What it solves

JIZURA is an automated composition tool for creating "lyric motion" videos (text-based music videos). It eliminates the manual effort of designing layouts, animations, and transitions for every line of lyrics, allowing users to quickly generate visually dynamic text animations synchronized to music.

How it works

The tool uses a library of 860 modular components across 10 categories (such as layout, appearance, persistence, exit, and camera effects) and 27 visual styles. Users input lyrics and music, and the system automatically assembles these components into a sequence of cuts.

Key technical features include:

  • Automatic Synchronization: Detects BPM and beats from uploaded audio to align cuts.
  • Randomized Generation: An "Omakase" (automatic) button randomly varies styles, color schemes, and compositions based on a seed.
  • Multi-platform Output: Works as a browser app (processing everything locally via WebCodecs) and as an After Effects panel (via ScriptUI or CEP) for professional editing.
  • Customization: Supports manual timing adjustments, specific layout overrides per line, and the ability to export configuration data as JSON for use in After Effects.

Who it’s for

  • Content creators and musicians who want high-quality lyric videos without manual keyframing.
  • Motion designers using After Effects who need a starting point or automated layout for complex text animations.
  • Users on mobile devices who need a simple way to generate social-media-ready vertical videos.

Highlights

  • Massive Component Library: 860 parts including specialized packs for Japanese style, kinetic typography, and horror themes.
  • Local Processing: No server uploads; lyrics and audio are processed entirely within the browser.
  • Professional Integration: Direct export to After Effects via JSON or dedicated panels to allow for fine-tuning.
  • ** uma Versatile Export**: Supports MP4, PNG sequences, and transparent PNGs (with green/black back options) for compositing.
  • Intelligent Typography: Features automatic character spacing and sizing adjustments for Japanese, Chinese, Korean, and English text.
