YouTube default thumbnail

Per YouTube’s guidelines, your thumbnail image should be 1280 x 720 pixels, with a minimum width of 640 pixels . An aspect ratio of 16:9 is ideal as it’s used most often in YouTube players and previews. Making a thumbnail image that’s too small is a big mistake.

Use video player plugin as thumbnail.
