Social Share Images per page and per video?

I have a social share image uploaded that is a screenshot of my homepage. But when I share a link to my photo gallery or contact page it just shows the main social share image regardless of the page link. Is there a way to determine a social share image per page?

AND VIDEOS PAGE

Currently sharing a link to a page created by the video page. it shows a white box with a grey line through it. The screenshot below shows this.  How do you define a social share image for video pages? it does not use the one for the main site.

You can add a social image per page in the page settings.

Can you explain how specifically for video pages. I've checked the settings for this collection and for each individual video page and the SEO settings do not have a social sharing option the way regular pages do. Are we missing something?

In this case it may use the video thumbnail, but would default to the social image for the main video page.
