Video Template Cover Art Available sizing

I was wondering if it is possible to acquire the preview cover art files for each of the video templates? They’re only posted in the tiny 590x332 dimensions. If I remember correctly, the authors are required to submit their cover art in at 1920 x 1080? It would be very helpful for those of us who use the cover art for their respective folder icons, making it easier to identify when seeking out/using one of the many downloaded templates.
