IMHO...
It's a great clip, but not because of the screen size.
I don't think it's really worth paying more for this feature since the smaller ones you provide are already of sufficiently high quality such that they can be easily played back in "full screen mode" without much loss in picture integrity. I mention this because many others deliver clips with a smaller default size and/or resolution; enlarging those to full screen only degrades the images more significantly.
So basically, I think there's only a small net improvement in quality (to your clips that are already quite good) at the expense of longer download times, increased memory usage, and increased cost. And, as you noted, the clip lengths are the same.
As for the clip's content, I love it. I haven't gotten to watch it fully in peace as yet, but it looks like a winner to me. (Mercedes(?) seems to really like being tickled..a rare find!) Keep up the good work, TIB. 😎
