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 audio mode.
Open vinnervi.com/subtitles, paste the X post URL (either x.com or twitter.com), pick a target language and a subtitle format (SRT, VTT, ASS, or TXT), and hit Generate. The finished subtitle file arrives in your Jobs tab and your inbox — useful for archiving political clips, breaking-news footage, or research transcripts across languages.
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.
