Video Downloader & Translator — MP4, HLS, m3u8 Stream

MP4/HLS/m3u8 video downloader + AI translator. Save any open stream, then translate & dub it into 30+ languages.

🎬 Save any open stream as a clean MP4 — then translate and dub it into 30+ languages. Dub Any Video combines two tools in one. First, a quick way to download open MP4, HLS (.m3u8) and MPEG-TS sources from almost any website and keep them as a single, tidy file. Second, an AI translator that re-voices a clip into another language with natural speech. Grab a playable source, keep it offline, or send it straight to translation — no extra software, nothing installed on your computer. ⬇️ DOWNLOAD — MP4, HLS, m3u8, TS It works as an MP4 downloader, HLS downloader and m3u8 downloader in a single click: • Grab a direct .mp4 file instantly. • Turn an .m3u8 playlist into ONE playable MP4, assembled right in your browser. • Merge fragmented TS and fMP4 / CMAF segments automatically — no command line, no extra apps. • As a stream downloader it listens to the tab and lists every open source it finds. • Nothing is re-encoded: the original quality stays intact through a fast, lossless "copy" remux. • Preview first — tell full-picture sources from audio-only ones, and play each inline before you keep it. 🌍 AI VIDEO TRANSLATOR & DUBBING — 30+ LANGUAGES Turn a clip into English, Spanish, French, German, Hindi, Portuguese, Arabic and dozens more: • A true video translator — translate video with real voice-to-voice dubbing, not just subtitles. • The original speech is re-voiced, so the result sounds natural rather than read aloud. • Going the other way? Translate video to English from any supported source. • Choose a language and a voice, then get a dubbed clip back. 🔒 PRIVATE & SAFE BY DESIGN • Segments travel straight from their host to you — never through our servers. • Protected / DRM material is never touched and never listed — by design. • No account is needed to find and keep open sources. ⚙️ HOW IT WORKS 1. Open a page and press play. 2. Click the extension — every open source on the tab appears. 3. Preview and pick the one you want. 4. Keep it as a single MP4, or hit "Dub" to translate it. ✅ SUPPORTED FORMATS MP4 · HLS (.m3u8) · MPEG-TS (.ts) · fMP4 / CMAF segments. 👤 WHO IT'S FOR Language learners, creators, marketers, educators — anyone who needs to keep a clip or watch it in their own tongue. 💡 WHY CHOOSE DUB ANY VIDEO Most tools only download or only translate. This one does both, so you capture a source and get it in any language without juggling separate apps or websites. ❓ FREQUENTLY ASKED QUESTIONS ❓ Which sites does it work on? 💡 Almost any page that plays an open stream. The source is detected automatically, while protected or DRM-locked playback is skipped and never listed. ❓ Do I need an account to save a file? 💡 No. Finding and keeping open sources is completely free and needs no sign-up. Only dubbing opens our website, where a free account starts the job. ❓ Will the saved file play everywhere? 💡 Yes. Segmented sources are assembled into one standard MP4 with a proper header, so it plays in any common player, not only inside the browser. ❓ Does it re-encode or lose quality? 💡 No. The original streams are copied as-is in a lossless remux, so the result keeps full quality and finishes fast. ❓ How many languages can it dub into? 💡 More than thirty. Pick a target language and a voice on our site, and the original speech is re-voiced for you. ℹ️ ABOUT DUBBING Dubbing runs on our website and needs a free account. The "Dub" button opens the site with the source link, so you sign in and start in seconds. Finding and keeping open sources works without any account. This extension never downloads or decrypts DRM-protected material and never bypasses a site's protection.
