When trying to investigate why thumbtime wasn't working as I expected I noticed that the reason for this was that the thumbnails were not being correctly generated (from this test page).
The thumbnail link which fails to load (https://upload.wikimedia.org/wikipedia/commons/thumb/6/6c/En_liten_film_om_GLAMig_data.webm/120px-seek%3D15-En_liten_film_om_GLAMig_data.webm.jpg) simply returns the error message:
There have been too many recent failed attempts (4 or more) to render this thumbnail. Please try again later.
Trying to render it at a different size (https://upload.wikimedia.org/wikipedia/commons/thumb/6/6c/En_liten_film_om_GLAMig_data.webm/150px-seek%3D15-En_liten_film_om_GLAMig_data.webm.jpg ) gives me
