Specify whether MediaConvert generates images for trick play. Keep the default value, None, to not generate any
images. Choose Thumbnail to generate tiled thumbnails. Choose Thumbnail and full frame to generate tiled thumbnails
and full-resolution images of single frames. MediaConvert adds an entry in the .mpd manifest for each set of images
that you generate. A common application for these images is Roku trick mode. The thumbnails and full-frame images
that MediaConvert creates with this feature are compatible with this Roku specification:
