Watch any video posted on X with translated subtitles overlaid on the player, or download a finished SRT/VTT/ASS file. Works on x.com and the legacy twitter.com URLs. 50 free credits at signup — no card required.
Pick the workflow that matches how you watch. Both use the same translation engine and the same 30+ target languages.
Install the VinnerVi browser extension, open any X post that contains a video, click the extension icon, and pick your target language. Translated subtitles appear on the X video player, synced to playback. X videos are usually short, so most translations cost a fraction of a credit at 3 credits per minute in speech mode.
When processing finishes, your subtitle file is available in History. If the browser extension is installed, it alerts you when the translation is ready. Download SRT, VTT, ASS, or TXT from History whenever you need it.
X is one of the fastest channels for breaking news, political commentary, and on-the-ground footage from every corner of the world — and most of it never gets captioned. A video clip from a press conference in Tehran, a market interview in São Paulo, a politician's response in Tokyo, or a livestream replay from Berlin can sit on X for hours before any English-language summary appears. The platform's built-in translation handles tweet text, but does nothing for the audio inside posted videos.
VinnerVi fills that gap. The browser extension overlays translated subtitles on the X video player as you scroll, so you can follow international news, foreign-language creators, and quoted clips without leaving the timeline. The URL workflow gives you a downloadable subtitle file — useful for journalists, researchers, and analysts who need to cite an exact transcript, build a translated archive, or share footage with colleagues who don't speak the source language.
Because X rarely carries built-in caption tracks, most videos run in audio-transcription mode at 3 credits per minute. X clips are short by nature so the per-video cost is typically tiny. Both x.com and twitter.com URLs work, including quoted retweets and replies that contain video. Live X Spaces audio is not supported — only finished video recordings — and X Premium is not required.
