To do a proper nice pro intro take a lot of effort resource and time, and the majority of time if its not topical to the video, viewers tend to skip it anyway. I have started just cut straight to a brief clip of something interesting, then fade into a brief 5-10 second theme tune shot of your logo to create a hook, then cut back to the conclusion that you showed your audience.
If you look at the best vloggers out there, they are not that flash. they are just good at setting up audience anticipation thro story telling. creating suspense, intruige etc. that way out trumps any special effects in a protracted, and irrelevant intro.
My opinion anyway. Please dont think I am happy with my intros tho. lol.
