Recently I was working on a Christmas production for a church and I decided to use one of my own motion backgrounds for the title. The title was Journey to the Manger, so I picked out one of my most recent Christmas motion backgrounds, Cradle at Night, and decided to build the intro in After Effects.
It was the perfect motion background to use because the subtle light burst accented nicely with the evening silhouette of the manger, creating a dynamic contrast of colors, ultimately making the text stand out. When looking for a great video loop to fill in for a project, look at the end result and work your way backwards. Imagine what it could look like, then tailor it down to what it should look like, and then finally, turn it into what it can look like.
And, if you are like the other hundreds of people that regularly download amazing moving backgrounds off of our site, you are sure to find exactly what you are looking for. I know I always do.
