Weibo Video Downloader · 微博视频下载
Paste a weibo.com post link and save the video as original-quality mp4 — works from outside China, no Weibo account needed.
Why download Weibo (微博) videos with ViralMint?
Weibo streams video through signed CDN URLs that expire after a session, which is why right-click-save never works and most online parsers break within weeks. ViralMint resolves the current signed stream for public posts at parse time and saves the highest tier Weibo serves (typically 720p or 1080p on original uploads). It works from outside mainland China without a VPN for most public posts. Combined with local Whisper transcription — which handles Mandarin natively — it's a practical research tool for tracking what's trending on Chinese social media without screen-recording.

Frequently Asked Questions
Do I need a Weibo account or a VPN?
Neither, for most public posts. Weibo serves public video to international visitors; ViralMint resolves the stream directly. A minority of posts are restricted to logged-in users — those need cookies from a Weibo session (Settings → Cookies).
Can it transcribe or translate the Chinese audio?
Yes. ViralMint runs Whisper locally, which transcribes Mandarin with strong accuracy. You get the Chinese transcript in the Videos page; pair it with the Translate tool for an English version — useful for competitor research on Chinese viral formats.
Why do other Weibo download sites keep dying?
Weibo's video URLs are signed and short-lived, and the signing scheme changes regularly. Server-based parser sites break every time it does. ViralMint ships yt-dlp locally and updates it continuously, so fixes arrive as fast as the open-source community lands them.

Supported URL Example
https://weibo.com/1234567890/O1a2b3c4dEquivalent yt-dlp command
If you already use yt-dlp, the desktop app's Weibo (微博) download is equivalent to running:
yt-dlp -f "bv*+ba/b" --merge-output-format mp4 "https://weibo.com/1234567890/O1a2b3c4d"ViralMint also auto-runs Whisper transcription, downloads the thumbnail, and extracts AI hook / structure / tone insights — steps that take a separate command chain in raw yt-dlp.
