Styled subtitle playback demo
Features
Drop a video, get subtitles. Local Whisper transcription with word-level timing, no cloud, and no API keys.
Show original and translation together, style each line independently, with automatic CJK font handling for Chinese, Japanese, and Korean.
Fonts, colors, shadows, glow, outlines — every visual property is yours to tweak. Add karaoke sweep, highlight, or bounce animations with fade, pop, and slide transitions. Eight pro presets to start, then make it your own.
Download as SRT for universal compatibility, ASS for advanced styling, or burn subtitles directly into your video with FFmpeg — three export paths, zero friction.

SubVela itself is open source, and the core app is MIT licensed. The Windows installer and translation features also rely on third-party components that remain under their own licenses.
Core app

Windows installer bundle
The Windows download includes FFmpeg and FFprobe. The bundled FFmpeg build is distributed under GPLv3, so the installer carries additional third-party license obligations beyond the MIT-licensed core app.

Third-party notices
The project also references other third-party components, including libmpv and the NLLB translation model artifacts used for local translation, under their own notices and terms.
