Your question seems misplaced. This venue is for dealing with an output named "AirHelp" from the Adobe RoboHelp application.
But I'm not sure where it actually should be.
Although, I think that if you wanted a video of an AIR app, you might need to use a tool that would simply record the screen as you manipulated the AIR app. Then produce a video from that.
Adobe offers a few tools that might help. Adobe Captivate has the ability to record your screen (or a smaller segment of the screen) and produce that as a video. There is another tool called Adobe Presenter Video Express that records your screen and produces a video.
Outside the Adobe realm, you might consider TechSmith Camtasia or TechSmith SnagIt to record your screen and produce a video.
And there are on-line tools, such as ScreenCastOMatic that can do it.
