Youtube field not showing creating blogpost

Hello,

I have set up a blog in which the editor can choose between a post with an image and a post with a video. I have created a post_video.html template, including the following region:

<perch:content id="video" type="youtube" width="743" height="387" label="YouTube URL" output="embed" autoplay="1" modestbranding="1" />

I've also added the API key to my config file.

Now when I'm creating a post, choose post_video as post type, I can't see a "YouTube URL" field.

What could be wrong?
