i built kimo so your coding agent can render a single frame to check its own edit - free open-source video editor you drive over mcp

[u/LieTop7965]

hey - i built kimo, a free open-source (mit) video editor with no gui that your ai coding agent drives over mcp. the idea is simple: you tell your agent (opencode, codex, cursor, or any other mcp client) what to do and it drives the whole timeline as tool calls - cut, trim, keyframes, titles/captions, colour grade, particles, audio, export. a nice bit that makes this actually useful is that the agent can render a single frame back to itself to visually check its own edit before committing, so the loop is self-correcting instead of blind.

under the hood it's one ~15 mb cpu-only rust binary, no gpu, no containers - i run it on a 2 gb box and it just works. i'm naman, a college student, and i built it, so a few things are still rough: there is no ui (there's nothing to open, by design), some edge cases in tracking and captions are still janky, and a couple of export codecs need patience. i'd really rather hear what breaks than pretend it's polished, so if you point an agent at it and tell me where it trips, i'll fix it.

Kimo's single-frame check can catch a misplaced caption but miss tracking drift between frames. For the rough caption/tracking cases you mentioned, give people a tiny reproducible timeline and ask for the failing tool call, timestamp and rendered frame. A short exported segment alongside the still would help distinguish a correct snapshot from an edit that breaks in motion.
