I want to try making my blog post thumbnails into YouTube video embeds, sort of like in this video.
However, I don’t see any Format option for posts as shown in this video, and what I’ve read suggests that a missing Format option is due to the theme.
Any tips/ideas on how to customize the thumbnails of posts would be appreciated.
I want to cut down on how many images I will be uploading to my website media over time by relying more on embedding than uploading image after image, essentially.
