What is this?
Subtitle Edit is an open-source subtitle editor: it creates, edits, converts and syncs subtitle files, with video playback built in so you can time lines against the actual media.

Since v5.1.0-rc13 it is signed and notarized, so it opens normally — no Terminal quarantine-removal step needed.

Only native Linux packages expect mpv and ffmpeg to already be present.

Older Windows 10 builds are end-of-life and may fail to start with a .NET runtime error (0x80131506).

Only optional online services such as translation, speech-to-text, OCR and text-to-speech send the minimal data needed for that request directly to the provider you picked.

It also offers optional translation, speech-to-text, text-to-speech and OCR through third-party online services.

The macOS .dmg and the Linux Flatpak bundle them; on native Linux packages you install them yourself.
