Video thumb preview not show on facebook

Hello, this is my video post

now I’m trying to get this when I post video post on facebook

but i get this

Facebook will pull whatever image is noted as the og image in your head php data (view source on that page to see which image is there in the og:image tag).

Usually you can do couple of things:
a) make sure the video thumb is grabbed as the ‘featured image’ for post
b) use Yoast SEO to custom specify an image you want to use for Facebook

Thank you Chris,

it’s strange because I’ve insert a featured image into post too. I’ll try with yoast tomorrow, thanks

All the best,
Antonio
