Hi
i tried to add video at the bottom of a article in news category exactly like you add in the blog articles but it was not working.
I used an article from the blog category and added it to the news category.
Then i was able to add video at the bottom but the problem is that i cannot hide the right image that has in the blog articles.
see here in the following reply which is private

Except if i can add video in the news articles so that i do not have to use the articles that are formatted for blog
