Thanks, for some reason the problem solved itself. Weird, thanks for help a lot tho!

Thanks for quick answer, hopefully i can solve this. Cheers!

Different sizes. For some yotube videos it’s 480 × 360 and for one vimeo it’s 640 × 427. Altho one video was saved as 1280 × 720 (even og dimensions in head meta are like this), but it’s still really small when sharing post on facebook.

I’ve found out that the thumbnails is probably supposed to be above 600px for facebook, how do i change that, so the video thumbnails done in my admin panel will be bigger?

I’ve managed to achieve video thumbnails by using “Video Thumbnails” plugin, where it sets featured image from video. It takes a quite big screenshots, but unfortunetly when i post it on youtube, the thumbnail is really really small, like 112×64 px.

Anyone has idea how to change it?

Thanks for answer. The thing is that the blog im creating is made for non-advanced users and i want to make it really simple for them. So as far it solves the problem, uploading Youtube thumbnail manually is far from the perfect solution.

Ps. Facebook cache isn’t a problem since i can test the links in facebook debugging tool.

You need to add this line in your functions.php to activate post thumbnails (which is featured image obviously):

add_theme_support( 'post-thumbnails' );
