Hey, we're glad you're here. Coub is a place where you can create and share short, looping videos with audio. We call them coubs. You can use up to ten source videos for your coub, so if mashups are your thing, you've come to the right place.
No. In short, coub is not a file format, it's a looped video which can be set to music. Coubs take less time to process than GIFs, are HD quality, and coubs show the video and audio sources, thus keeping you aware of the content's origins.
Your timeline is a stream of all your friends' coubs and channels that you follow. Follow friends on Coub, follow channels related to your interests, and you'll have a pretty cool timeline. You can find the featured Channels section at the top of your screen.
If you want to share a coub with your Coub friends, recoub it. If you want to share it on social networks, you'll find all sorts of sharing options under each coub: Twitter, Facebook, Tumblr, Pinterest, etc. You can also embed coubs on your blog or website, here's how.
