AI Architecture Analysis

This repository is indexed by RepoMind. By analyzing SubtitleEdit/subtitleedit in our AI interface, you can instantly generate complete architecture diagrams, visualize control flows, and perform automated security audits across the entire codebase.

Our Agentic Context Augmented Generation (Agentic CAG) engine loads full source files into context on-demand, avoiding the fragmentation of traditional RAG systems. Ask questions about the architecture, dependencies, or specific features to see it in action.

Installing Subtitle Edit on macOS (Unsigned App)

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:

  1. Download and double-click the .dmg file to mount it.

  2. In the window that appears, drag Subtitle Edit.app into your Applications folder.

  3. Open the Terminal app (you can find it via Spotlight or in /Applications/Utilities/).

  4. 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"

Linux

Requires mpv and ffmpeg (ffmpeg is normally already installed) to enable video functionality.

Debian/Ubuntu

sudo apt update && sudo apt install -y mpv libmpv-dev ffmpeg

Arch

sudo pacman -S mpv ffmpeg

Fedora

sudo dnf install mpv-libs ffmpeg

openSUSE

sudo zypper install libmpv1 ffmpeg

⚙️ Note: The provided builds are self-contained and do not require a separate .NET installation.

🔒 Privacy

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.
