Add French Subtitles to Video
ViralMint is a free French subtitle generator — Whisper transcribes your video locally and adds accurate Français captions you can burn in or export.
Free French subtitle generator, powered by local Whisper
ViralMint adds French (Français) subtitles to any video using local Whisper transcription, which handles French liaison, elision and accented characters cleanly. Paste a video and get word-level French timestamps in seconds, then burn word-by-word animated captions or export a .srt/.ass file. Need a French cut of an English video? translate-and-dub transcribes the original locally, translates it to French, and re-times the subtitles — handy for reaching audiences across France, Québec, Belgium and francophone Africa. Nothing uploads, there's no per-minute cap, and there's no watermark on the output.
How to add French subtitles to a video
-
Open the caption tool
Launch ViralMint and open Tools → Captions. It accepts mp4, mov, mkv and webm.
-
Drop in your video
Local Whisper transcribes it into French (Français) with word-level timestamps — on your machine, nothing uploads. If the audio is another language, translate-and-dub can convert it to French first.
-
Style or export
Burn word-by-word animated French captions (viral / classic / bold), or export a standalone .srt / .ass file for any editor.
-
Render the mp4
ViralMint burns the French subtitles in with FFmpeg and writes the final mp4 — original untouched, zero watermark.
Frequently Asked Questions
Does it handle French accents and special characters?
Yes. Whisper outputs proper French orthography — accents (é, è, à, ç), apostrophes for elision (l', d'), and liaison-aware word boundaries — so the subtitles read naturally without manual fixing.
Can I get French subtitles from an English video?
Yes, via translate-and-dub: it transcribes the English audio locally, translates to French, and re-times the captions for an accurate French version.
Can I export an .srt for my editor?
Yes. Export a standalone .srt or .ass file, or burn the French captions directly into the mp4 with the viral / classic / bold preset.
