Hi there, when I include a video block in a blog post and select it to NOT autoplay/loop it will come out as a big black rectangle. I have included (intentionally) a static image in the first frame of the video which I would like to be the still image when the video has not started playing yet.
When the video is selected in win file explorer the preview window shows the still image.
Also when I copy the video address from the blog post and open it in a separate window the still image shows ??
