Motion Skill

Motion Skill is a voice- and script-driven motion graphics video tool that uses Codex and Remotion to turn audio and text into editable videos.

Motion Skill is an open-source tool designed for creators who want to produce videos without appearing on camera. It functions as a voice-to-video skill and an editable Remotion project, allowing users to organize audio, real footage, captions, and motion graphics. The system uses Codex to understand content and arrange shots, Python for time and constraint checks, and Remotion for previewing and rendering. It features 96 motion studies, 19 categories, 10 production components, and 5 semantic structures. The software supports script and voice modes, 16:9 default aspect ratios, and custom dimensions like 9:16 and 3:4. Users can provide their own scripts or voice recordings, while optional integrations like ACE-Step handle local music generation and local Whisper manages audio transcription.
