I had a question about the intro video that I use. I paid someone on the website Fiverr to create the intro. My recommendation is if you go this route, you might shorten an intro video to 3 - 5 seconds. Mine is a little long at 10 seconds.
Go to Fiverr.com, search "logo intro video", and find the vendor you would like to use. I always look for those that have done the most transactions with the highest ratings.
