Thumbnail Generation
This section defines the behavior of the thumbnails generation. Thumbnails are just preview images supported by the DASH spec (check DASH IF IOP v4.3 spec and, in particular, the paragraph 6.2.6 Tiles of thumbnail images). You can see them when scrolling video forward or backwards, just as you see it on YouTube, for example. These settings are used in the Image Extraction Phase.
