Hi, I currently have the blog post featured image set to show on all posts. Ideally i would like to be able to HIDE it on Video posts so that the video instead can be at the top of the post.

Can you help me to know how to set this for these specific posts only

I figured it out ... alll good!

.post_format-post-format-video .post-featured-img {
    display: none;
}
