fastCutVid

fastCutVid is a lightweight, native video editor designed for quick trimming and sequencing without the overhead of full-featured suites. Built in Rust with an egui interface, it lets you load footage, find key moments, split clips, and arrange sequences efficiently. The tool exports both MP4 files and portable JSON timelines that AI agents can parse and process identically to human editors.

It's purpose-built for workflows where you need to cut video quickly before passing it to an AI agent for further processing. The maker built it with OpenAI Codex to solve the problem of agents struggling with timing and cutting based on transcription alone. Projects reference source media rather than bundling it, keeping file management simple.
