Coub Downloader
Save a Coub as a real MP4 with its sound — the loop and the audio arrive as one file, not two.
Why download Coub videos with ViralMint?
A Coub is not one file. The platform stores the looping video and its audio as separate assets and marries them in the player, which is why so many Coub downloaders hand back a silent clip — they fetch the video asset and stop. ViralMint muxes the two into a single MP4 so the result plays the way the Coub does. The loop itself is a player behaviour rather than something baked into the file: a Coub that appears to run for a minute is usually a few seconds of video repeated, so expect a short file and set your editor to loop it. Coubs are small and quick, which makes them a good candidate for batch downloading a whole channel in one pass.

Frequently Asked Questions
Why is my downloaded Coub silent?
Because the tool you used fetched only the video asset. Coub keeps the audio as a separate file and combines them at playback, so a downloader has to fetch both and mux them. That is what ViralMint does by default.
Why is the file so much shorter than the Coub I watched?
Coub loops a short clip. The video asset really is only a few seconds long — the length you experienced came from the player repeating it. Loop the file in your editor to reproduce it.
Can I download the audio only?
Yes. Use the Extract Audio tool on the downloaded file to write an MP3, which is the usual way people lift the music from a Coub they liked.

Supported URL Example
https://coub.com/view/abcdefEquivalent yt-dlp command
If you already use yt-dlp, the desktop app's Coub download is equivalent to running:
yt-dlp -f "bv*+ba/b" --merge-output-format mp4 "https://coub.com/view/abcdef"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.
