Scarlet 0.1.22 for Ubuntu 24.04 x86-64 (Linux preview)
Download Scarlet 0.1.22 for Ubuntu 24.04 x86-64
From the directory containing the download, run the following command. Ubuntu will install the required FFmpeg and GStreamer packages alongside Scarlet.
sudo apt install ./Scarlet-0.1.22-Ubuntu-24.04-amd64.debOpen Scarlet from the applications menu. Local transcription downloads its speech model on first use.
The packaged editor was tested on Ubuntu 24.04 under X11 on an AVX2-capable runner. The test imported an H.264/AAC clip, transcribed it with the bundled Whisper runtime, played the timeline and exported an MP4. Physical microphone capture, native Wayland and older CPUs without AVX2 still need hardware testing. Build and test run

Scarlet Early Access 0.1.4
Scarlet Early Access 0.1.4 adds a usage-reporting switch. Open Settings → About and turn off Send usage reports to stop sending events. This update also fixes dependency advisories and includes licence notices and a credit for the filler-word model in the app.
Install or update
Quit Scarlet Early Access before installing the update. Install over your existing Early Access copy to keep your projects and settings.
On a Mac, open the disk image and drag Scarlet Early Access into Applications. First-time users also need FFmpeg and FFprobe. Download the helper and run bash ~/Downloads/Install-Scarlet-FFmpeg-macOS.sh. The helper verifies the downloads before installing them. These Mac previews are ad hoc signed and unnotarized.

Scarlet Early Access 0.1.3
Scarlet Early Access 0.1.3 adds /dialogue-pass for a cut-only first edit. It can remove false starts, redundant takes and pauses while keeping the speaker’s meaning and timing. Editors who customized /first-cut-dialogue keep their existing guide as a separate command. Screen framing also follows the footage and the requested composition. Browse the seven editing workflows

Scarlet Early Access 0.1.2

Downloads
First installation
On macOS, download the FFmpeg setup helper and run bash ~/Downloads/Install-Scarlet-FFmpeg-macOS.sh in Terminal. It downloads FFmpeg and FFprobe from their publisher and checks their hashes. Open the disk image and drag Scarlet Early Access to Applications. The Mac builds are ad hoc signed and unnotarized. Apple’s first-open instructions
On Windows, install the media tools with winget install --id Gyan.FFmpeg.Essentials --exact in PowerShell, then run Scarlet Setup. The installer is unsigned and uses CPU transcription and speaker analysis. Windows may show a warning when you open it.
Connect Claude Code or Codex in Settings → General. Scarlet stores projects locally. Your connected AI provider can receive project context such as transcript excerpts and frames when you ask it to edit.
Usage telemetry
Packaged builds send usage events to PostHog in the US by default. They cover engine starts and project count, feature use, editing and transcription requests and their outcomes, export outcomes, and explicit Keep, Revise, or Undo actions on applied edits. Revise and Undo are counted when you submit the request. An anonymous installation ID links events across sessions, and an installation-specific code links decisions about an edit.
Settings → About lists every event field and tracked feature. Reports exclude footage, audio, transcripts, project names, file paths, prompts, edit titles, revision text, and raw project and edit IDs. To turn reporting off, set SCARLET_TELEMETRY_ENABLED=false in the app’s launch environment and restart Scarlet.
