Cutting Room

Record a screen capture, cut it, caption it, export it. Runs in the browser with your own key.

Cutting Room replaces Skreencast Pro.

Teardown

3 parts, wired together

  1. 01MediaRecorder APITODO — captures the screen and microphone straight from the browser, no native app to install.
  2. 02ffmpeg.wasmTODO — trims, crops and re-encodes locally, so the footage never leaves the machine.
  3. 03Whisper APITODO — turns the audio track into a caption file. This is the only step that spends your key.

What it does

TODO — replace this placeholder description.

Cutting Room records a screen capture, trims it, burns in captions and exports an mp4. Everything except transcription happens on the machine it runs on, so the footage never uploads anywhere. Transcription calls the Whisper API with a key you supply and pay for directly — a twenty minute recording costs a few cents.

It handles the loop most screen recordings actually go through: capture, cut the dead air off both ends, generate captions, export. Nothing beyond that.

Run it yourself

Bring your own API key. Three commands from clone to running.

$ git clone https://github.com/rebuiltlabs/cutting-room.git$ cd cutting-room && npm install$ cp .env.example .env  # add your own API key

What I cut

Where it stops short of Skreencast Pro

  • TODO — no cloud storage. Exports land in your downloads folder and nowhere else.
  • TODO — no team library, no sharing links, no comment threads.
  • TODO — transcription runs one file at a time, not in a queue.
  • TODO — export tops out at 1080p; there is no 4K path.
