Videos in blog posts

I don’t know WordPress but if you can post via HTML you should be able to do the same.

I’m using YouTube to do this. You just create an account there and upload your videos and they provide the HTML code to put on your site.

Not sure if you’ve seen this, but there is a media insert plugin that works great for video.

You can find the plugin here:
