This WordPress plugin makes embedded media responsive.
To embed a video or another object into a WordPress post or page, place its URL into the content area. 
Make sure the URL is on its own line and not hyperlinked (clickable when viewing the post).
WordPress will automatically turn the URL into a YouTube embed and provide a live preview in the visual editor.

When placing a YouTube or Vimeo video within the first 4000 characters of a post, the thumbnail of that video will automatically be uploaded and set as the featured image for the post as long as the post does not already have a set featured image.
In addition, after setting the video thumbnail as the featured image, an “is_video” post meta field is updated to allow for the use of conditional statements within your loop.

Automatic Featured Images from Videos

Tried this a bunch of times and it doesnt work. No errors or warnings, it just never sets the featured image

No longer works

An essential part of our Wordpress website. Saved hours of work. Thanks very much.

Just cool

If a YouTube or Vimeo video embed exists near the start of a post, we'll automatically set the post's featured image to a thumbnail of the video.
