Help me, please

I'm working on putting some posts together for this blog, but I need some help from my fellow bloggers. Can you guys help me understand how to get a video up. I have found some Pilots videos on other sites, and on YouTube but am a complete idiot on how to put them in my post. I know that some of you do it quite often, and would love some help. Thanks in advance to all you wonderful, helpful blog friends.
