My new project deals with ARD-Mediathek. Not all videos have a 1x1 image, that could be used as cover thumbnail. And non square images do not please me as thumbnails, because of their aspect ratio is not being preserved ( see here [Preserve aspect ratio for non square cover thumbnails](https://community.mp3tag.de/t/preserve-aspect-ratio-for-non-square-cover-thumbnails/71974) ). If you could fix that, I would also use rectangular thumbnails, and consequently always have thumbnail and full cover urls.

Thumbnail is missing:

Rectangular Thumbnail is distorted:
