Styled subtitles

Pick one of twelve presets, or just describe the look in plain words: "yellow text, black outline, bottom." The burn runs locally on ffmpeg: no upload, no queue, no account. Several languages? Each SRT gets its own finished video.

Translate subtitles

Hand over any SRT and name the languages you want. Several at once is fine, one pass covers them all. Every line keeps its exact original timing, appearing and disappearing at the same moments as before. Before delivery, the result is checked for lines that run too long or read too fast.

Short clips

Timecodes in, vertical shorts out: reframed 16:9 → 9:16, named, and ready for subtitles. Or hand over the transcript and AI picks the moments that work as shorts: opens on a hook, rides the reaction to its peak, cuts before the energy drops. 30–90 seconds each.

Dubbing and lip-sync

One run takes a file, a whole folder, or a YouTube/TikTok URL and dubs it into several languages from a single upload. Videos over the plan limit split, process, and merge back on their own; an interrupted run resumes exactly where it stopped, never re-billing finished parts. Dubbing clones the original voice into the new language, and lip-sync moves the mouth to match that cloned audio.

Subtitles from speech (STT)

No subtitles yet? Speech-to-text runs on Perso's servers and uses credits to turn the video's audio into an SRT in the original language, for one file or a whole folder. Every step after the SRT exists is free: translating, styling, burning.

Voice separation

Splits a video or audio into clean tracks: the voice and the background. With several speakers, each person's voice comes out as its own track. Swap the soundtrack, remaster the dialogue, or reuse any track on its own.

Free where it can be. Paid where it must be.

MIT, free and open-source. Everything that runs on your machine costs nothing and needs no account: styling and burning subtitles, translating an SRT you have, cutting clips at timecodes. Credits come in only when a job runs on Perso's servers: dubbing, lip-sync, voice separation, and speech-to-text, billed per processed second via the Perso Dubbing API.

No setup ceremony. The first time a server job runs, a browser opens: sign in, one click, key stored encrypted. Free steps never ask.
