When you are editing a Post/Page, just click the button “WP Money Machine Video”
There you will see a Popup where you can select the video (you need to have previously created it under WP Money Machine Pro > Videos).
If you want to customize the video, you can fill the optional settings (skin, player, etc); then just click “Ok” and the shortcode will be inserted in your post/page. Then just save the post you were editing and watch the result.
