The Mux Developer Hub

Welcome to the Mux developer hub. You'll find comprehensive guides and documentation to help you start working with Mux as quickly as possible, as well as support if you get stuck. Let's jump right in!

Get Started


Getting a thumbnail or poster image with Mux Video is easy. Just plug a Playback ID into the Image URL API and get your first image. Use the time querystring parameter to choose a thumbnail time (in seconds).


Of course, you might want to do more than just this, like cropping the image or choosing a different frame. The Image URL API supports a number of other options via querystring parameters: width, height, rotate, cropping, and more.


Note that there is a default limit of 30 thumbnails per asset. If you need more, contact Mux.

See the Thumbnail Reference for detailed documentation.
