Video Use
This project is an AI video post-production suite that uses large language models and programmatic tools to automate editing, transcription, and subtitle generation. It functions as an AI editing agent that translates natural language instructions into shell commands, providing a programmatic interface for manipulating media via FFmpeg.
The toolkit includes a motion graphics engine that generates technical animations and visual overlays through code-driven rendering and mathematical definitions. It distinguishes itself by combining an AI-powered transcriber for word-level timestamps with an automated system for removing filler words, false starts, and dead space.
The system covers a broad range of post-production capabilities, including audio-based video cutting, cinematic color grading through filter chains, and the integration of synthetic AI voiceovers. It also provides observability tools such as timeline visualization through composite filmstrips and waveforms, as well as self-evaluation loops to validate rendered output for visual jumps or audio pops.
Session data and editing history are persisted in text files to maintain project continuity across different execution contexts.
