Full Changelog: v0.2.0...v0.3.0

Snitt 0.2.0

Snitt 0.2.0

v0.1.0 could record a window and trim it. 0.2.0 is where Snitt became an editor —
123 commits, 304 files, +28,013 lines — plus on-device transcription, a real agent
surface, and an open-source licence.

Universal (arm64 + x86_64), signed with Developer ID, notarized and stapled.

The editor

The timeline stopped being a scrub bar.

• Waveforms and a filmstrip in every track — log-scale, with clipping marks, one
  band per audio source. Dark surface, orange waveform.
• Per-track gain and mute, applied live in the preview and honoured by the export
  mix.
• Crop as a bounding box you drag and adjust before committing — nothing reaches
  the edit until you press Apply.
• Auto-deep-trim: cut the spans where nothing happens, with presets and the
  criteria behind them stated. An automatic fold says what it removed.
• Expanded folds insert space, so the playhead skips them instead of walking
  through footage that isn't there.
• A chapter panel for markers, with typed times and drag-to-move.
• Transport: rewind, scrub-stops-playback, zoom and snapping with on-screen
  controls.
• Opens centred at 75% of the screen.

Transcription — on device, and editable

Runs on your Mac with Apple's recognizer. The audio never leaves the machine.

• The transcript is an editing surface: click a word to jump there, select a phrase
  and delete it to cut those seconds.
• Correct a word in place — double-click, type, done.
• Tell it what to expect. A recording carries a vocabulary of the symbol names,
  file names and product names a general speech model has never heard, and
  re-transcribes against them.
• The spoken word highlights as playback reaches it, and the transcript breaks into
  lines at the speaker's own pauses.
• Confidence is rendered, not hidden — a word the recognizer doubted looks doubted.
• Marker transcripts export as WebVTT subtitles.

Agents

• snitt_auto_deep_trim, snitt crop, pause/resume, and screenshot-the-recording over
  both MCP and the CLI.
• snitt setup registers the MCP server with agent hosts.
• Snitt starts on demand when a client finds it closed.
• A client can report input the OS never saw — an agent's synthetic keystrokes and
  clicks land in the event log as content-free beats, and clicks can be drawn on the
  exported video.
• Agent-initiated recordings disclose themselves in the UI.

Capture and export

• Pause and resume a recording, from the menu bar or over the agent surface; a
  paused recording looks distinctly paused.
• Microphone recording from the GUI, with a warning when your speakers will bleed
  into the mic.
• A configurable save destination.
• Customizable hotkeys for record and marker.
• Export gained a resolution knob and a pre-flight menu that prices every option
  before you commit to one.
• .snitt bundles get a Finder icon drawn from the recording itself.

The project

• Licensed MPL-2.0, with a contributor agreement — file-level copyleft, so a
  commercial competitor cannot take the code closed, and GPL-compatible.
• A README, a spec conformance pass, and CI.

Notable fixes

• Clicking a transcript word highlighted the word before it — intermittently. The
  seek target quantizes to 1/600s, landing up to 0.8ms before the word's start, so
  the previous word won the lookup whenever a word's start time rounded down.
• The Settings window was released out from under itself — a use-after-free that
  crashed shipped v0.1.0 when you toggled "Log input events".
• Timeline gestures were interpreted on the wrong axis after the view moved to
  output time.
• Transcription only covered the tail of a recording; it now runs per utterance.
• Silence detection measures against the 90th percentile, not the max, so one loud
  moment no longer makes a quiet recording read as busy.
• snitt trim discarded existing cuts instead of preserving them.
• Adjusting gain no longer resets the playhead to the start.
• events.json now guards its schemaVersion, like edit.json.

Upgrading

edit.json and events.json from v0.1.0 open unchanged — there is a pinned test
against a real captured v0.1.0 bundle, including the read-then-save path.

Existing installs with automatic checks enabled will be offered this build by Sparkle.
Updates are verified three ways before they install: TLS to github.com, the Developer ID
signature, and an EdDSA signature over the archive.
