First just so you know we are not the metasploit forum, nor directly a support resource for metasploit. Having said that yes it is in BT4 and there are members here who can or will answer questions about it.
Now as for your videos you can post them so long as it meets the requirements of the "readme" in the video section, and does not directly violate the rules of the forum.
Take a look at both of those before posting to ensure compliance.
Also this is a question and as such has been moved to the beginner forum.
