Captions that move with every word.

VIDRA times captions to the voice word by word — the karaoke style that keeps people watching on mute — in the lettering style you choose, and it auto-subtitles any line spoken in another language. No manual timing, no caption files, no drift.

Every image and clip is generated uniquely for you, never reused — no stock footage, no shared library.

What it is

Most short-form is watched on mute, so captions aren't optional — they're the difference between a scroll and a view. VIDRA generates word-timed karaoke captions automatically, highlighting each word as it's spoken, in a lettering style you pick. When a character speaks a different language from the video's base, it adds translated subtitles for those lines automatically, the way films handle foreign dialogue. You never touch a timeline or upload an SRT.
