Welcome to subtitleedit-avalonia — the early preview of the next major release of Subtitle Edit!
This version is being rebuilt using Avalonia UI to enable true cross-platform support.

Because Subtitle Edit is not signed with an Apple developer certificate, macOS will block it by default. You can still install and run it by following these steps:
-
Download and double-click the
.dmgfile to mount it. -
In the window that appears, drag
Subtitle Edit.appinto yourApplicationsfolder. -
Open the Terminal app (you can find it via Spotlight or in
/Applications/Utilities/). -
In Terminal, run the following commands to remove macOS’s security quarantine flag and add adhoc code signature:
sudo xattr -rd com.apple.quarantine "/Applications/Subtitle Edit.app"sudo codesign --force --deep --sign - "/Applications/Subtitle Edit.app"
Requires mpv and ffmpeg (ffmpeg is normally already installed) to enable video functionality.
sudo apt update && sudo apt install -y mpv libmpv-dev ffmpegsudo pacman -S mpv ffmpegsudo dnf install mpv-libs ffmpegsudo zypper install libmpv1 ffmpeg⚙️ Note: The provided builds are self-contained and do not require a separate .NET installation.
Subtitle Edit is an offline, open-source application.
It does not collect, store, transmit, or analyze the content of your subtitle files, media files, or any associated metadata — not for analytics, not for model training, and not for any other secondary purpose, now or in the future.
All core features, including editing, converting, video playback, and local auto-backup, run entirely on your device.
If you choose to use optional third-party online services within Subtitle Edit (such as translation, speech-to-text, text-to-speech, OCR, or dictionary/lookups), only the minimal data required to perform that specific request is sent directly to the selected provider. Any such data transfer is governed by the provider’s own privacy policy, and Subtitle Edit does not retain or forward this data in any way.
Subtitle Edit aims to give you full control over your files — your data stays yours.
