Aegisub vs Subtitle Edit
Side-by-side comparison of features, pricing, ratings, and alternatives.
Aegisub is a free, cross-platform, open-source subtitle editor focused on advanced timing and styling rather than basic caption entry. It includes a real-time video preview synced to the subtitle track, waveform/audio-based timing tools for lining up dialogue precisely, and a powerful styling system historically favored by fansub and anime subtitling communities for karaoke-style effects. Distributed under BSD-style open-source licenses with development hosted on GitHub, Aegisub supports English, Spanish, Turkish, and Simplified Chinese interfaces among others. It remains widely used for advanced typesetting work that goes beyond what mainstream captioning tools support.
Subtitle Edit is a free, open-source Windows/Mac/Linux application for creating, editing, and converting subtitle files, developed by Nikolaj Lynge Olsson. It plays video alongside the subtitle timeline for accurate synchronization, converts between dozens of subtitle formats, and offers optional integration with third-party services for translation, speech-to-text, text-to-speech, and OCR of image-based subtitles. The app is offline-first and states it does not collect, store, or transmit subtitle or media content, appealing to editors who work with sensitive or unreleased footage. It's distributed under an open-source license with active development on GitHub, and includes local auto-backup so in-progress edits aren't lost.
