Thumbnail Generation transform

A thumbnail generation transform is an operation that generate a thumbnail image, a series of thumbnails images or a sprite for a given input content.


Thumbnails generation is only available for MP4 content and requires a server manifest (.ism) file provided as input to the job.

Thumbnails generation transforms are not exposed in the UI and can be created using the transform endpoint in MK.IO API.

When selecting an thumbnail generation transform, you will need to select the source asset, and select the .ism manifest associated with asset. If you have assets in smooth streaming format you will first need to convert them using one of the Asset Conversion Transforms we provide.

Sample thumbnail generation transforms are provided in the Generate thumbnail images page.

Once thumbnails are generated, you can create a new streaming locator and use a Predefined_DownloadOnly streaming policy to retrieve the download URLs.
