Making my video - continued

We have found a technique we would love to use in our video called ducking which is used for many media topics such as radio (when they talk about a song over it playing) or when a film is advertised and they use a track from it while they use some dialog from the film over the top then it would end with just hearing a track for a few seconds louder. Here is a song that uses this technique by F.I.R which is called 'Our love'.
