Get Started

Thumbnails

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).

GET https://image.mux.com/Dk8pvMnvTeqDk9dy5nqmXz02MM4YtdElW/thumbnail.jpg?time=35

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.

GET https://image.mux.com/Dk8pvMnvTeqDk9dy5nqmXz02MM4YtdElW/thumbnail.png?width=400&height=200&smart_crop=true&time=35

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.
