プロジェクトの歴史

Subtitle Edit was developed as a free, open-source editor for video subtitles and accumulated support for hundreds of text, binary, and image-based subtitle formats.

The project later undertook a ground-up Avalonia rewrite. Subtitle Edit 5 retained the core editing workflow while adding a shared cross-platform codebase, a JSON settings format, and bundled media components in selected packages.

採用の歴史

Subtitle Edit became a mature open-source Windows subtitle workstation with extensive format support and workflows for timing, waveform editing, OCR, spell checking, and conversion.

Subtitle Edit 5.0.0, released in June 2026, brought the project to Windows, Linux, and macOS through one Avalonia-based codebase. The project continued to offer Subtitle Edit 4 for older Windows systems and specialized workflows not yet present in the rewrite.

使われ方

Users open or create subtitle files, align text with video or waveforms, repair timing and formatting, convert among more than 380 formats, and save or export the result.

Optional workflows can generate subtitles through speech recognition, translate text, OCR image-based subtitle streams, or burn subtitles into video. Some integrations use third-party online providers, but the core editor operates offline.

Subtitle Edit 5 stores settings in Settings.json within its platform data folder. Official documentation provides an in-application shortcut for opening that folder.

パッケージ好きにとっての重要性

Subtitle Edit combines work often split among several media tools: format conversion, timing repair, waveform synchronization, OCR, speech recognition, translation, and subtitle rendering.

The fifth-generation rewrite is especially notable to packagers because it replaced the Windows Forms architecture with a cross-platform application and added native macOS and Linux distributions while retaining portable builds.

タイムライン

• Before 2026: Subtitle Edit developed into a feature-rich Windows subtitle editor with broad format and media-tool support.
• 2026: Subtitle Edit 5.0.0 introduced a rewritten Avalonia application for Windows, Linux, and macOS.
• 2026: Subsequent Subtitle Edit 5 releases continued expanding the new cross-platform generation while Subtitle Edit 4 remained available.
