Using the “Blog” add-on I’m showing only the excerpts for the main blog page.
If no Post Format is set, a post which begins with a video URL won’t display the video but just the text beneath it, following the word count rule you can set within the aforementioned add-on (55 words default).
Instead, if I set the Video Post Format, it display the video as expected, but, it also displays the full text. (I think this post explains this behavior, right?)
What if I need to write a lot about a video and need a read more link?
Is it possible to display the video and an excerpt automatically?
BTW, if you use the read more button in the editor
it works.
