Edit a video by talking about it — cut out a part, join clips, change the speed, even out or replace the sound, make it vertical — and add subtitles made from what is said in it, or captions and titles placed on screen (telops). Uses ffmpeg in the terminal and whisper.cpp for the speech, writes a new file beside the original, and opens the result in the pane on the right of the terminal (showInPane). Use when the user asks to trim, cut, join, speed up, resize, subtitle, caption, translate the…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Edit a video
The user points at a video and says what they want in plain words. They do not write ffmpeg
commands; you do, in the terminal, and show them the result. Talk to them about their video —
the part from 0:12 to 0:40, the subtitles, the title at the start — not about codecs and filters,
unless they ask.
## What you need
- `ffmpeg` and `ffprobe`. Check with `ffmpeg -version`. If it is missing, say so and give the
install command (`brew install ffmpeg` on a Mac); do not install it yourself.
- For subtitles or captions drawn onto the picture, ffmpeg built with libass. Check:
`ffmpeg -hide_banner -filters | grep -E ' (subtitles|ass) '` prints two lines when it is.
- For subtitles made from speech, `whisper-cli` from whisper.cpp (`brew install whisper-cpp` on a
Mac; the same package MulmoTerminal's voice input uses) and a model. Look for one MulmoTerminal
has already downloaded, in the workspace's `models` folder:
```sh
ls "${CLAUDE_CWD:-$HOME/mulmoclaude}/models"/ggml-*.bin
```
Use the file you find (prefer `ggml-large-v3-turbo.bin` when there are several) as `$model` below.

How to install
mdr add receptron/mulmoterminal/mulmoterminal-video-edit@sha256:41791c7756780402The line at the top of this page pins the label git:20261021.7fc4c50, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
