With AV content, it's possible to provide a thumbnail, or a placeholder canvas to be shown before the content is displayed, but there is no way to provide thumbnails for time-stops.

It is supported by WebVTT: https://www.webtvsolutions.com/support.php?s=ws_webtv_docs&d=clips_video_thumbnails&lang=en with additional support for a spite-map style URLs.

Taking an example from the archive.org IIIF implementation of AV content, they have a list of thumbnails for the various time-stops that are used on the main site for previews while scrubbing.

For example: https://iiif.archive.org/iiif/3/APOLLO16MMLAUNCHVIEWS/manifest.json

Has the following thumbnails attached:

However, there no duration to tie them back to the canvas duration.
