Video Thumbnail Transformations

Generate thumbnails from your videos using our transformation parameters.

​
Basic Usage

​
Timestamp Selection

Generate a thumbnail at a specific timestamp:

thumb-so_5.0

The so (seek offset) parameter specifies the timestamp in seconds. Default 5.0.

​
Combining with Image Transformations

Thumbnail generation can be combined with other image transformations:

thumb-so_10.0,w_300,h_200,c_fill

Thumbnails support all image transformation parameters. Refer to the Image Transformations documentation for the complete list of available parameters.
