Is it possible to change trailer thumbnail to a promo still because of low quality?

@Maya​ hmm interesting. Is it different for newer shows? Because a lot of newer titles have a promo still which is much higher quality than the trailer. Also, I've looked through the trailer for the title I posted and the thumbnail isn't even in the trailer, it's just a low quality image from somewhere else.

@Adam1234​ - Can you post a link to one of the newer titles you are referring to?

here is one, a new season just came out for this show. You'll see the aspect ratio and the watermark from the trailer aren't there and if you reverse search the thumbnail, it's a promotional still image and not a screenshot from the show or trailer itself.

@Adam1234​ - Thank you for providing the example! In certain cases, thumbnails for featured videos may be manually applied by our Editorial team which is why they might differ from others. 

@Maya​ oh ok, so is there no chance of updating it for this specific show? All the trailers came out in the 90s or early 2000s so the thumbnails are very low quality

@Adam1234​ - Correct, they can only be from the current main trailer displaying on them.
