When it comes to audio and video files - some companies reserve the right to make these files available freely and thus have to be purchased to gain the right to use these types of files. This is the main reason why you will find that we have not been able to make any preset Video FX templates available with backgrounds and audio files.
But the great thing is that you still have preset templates to that you can simply add your own background and audio files: VideoFX template Basics
With that said, we have found some great resources that will help you source some really awesome (Royalty-free) backgrounds and/or audio files:
