Linking audio to visuals and applying P4 (d)

As you can see from the screenshot Adobe After Effects reflect all the changes in the song. The audio from the actual shots are on the first audio line but it is disabled as they were only used to match the shots with the music. So all the shots are being matched with the song playing on the second audio line in the timeline. 

When the editing process was finished I removed the sound from original videos as it was no longer useful. I clicked on unlink and separated video and its sound. 

Than I clicked on an original music track and deleted it.

Below you can see the picture of the audio mixer, it allowed me to control the volume of the music video, if the volume would be too loud that the quality of sound would be bad the indicators would turn red showing that the frequency is too high. By adjusting the level of volume I would be able to solve that problem. This helped me to improve the quality of the music video as if the sound was too loud then this would be uncomfortable for people to watch it.

I also used sound effects panel to control the sound. As some moments I wanted the song to gradually become more loud when it starts I went to Sound Effects Control and then to the volume.

As you can see, the in the timeline the volume is now gradually goes up at the beginning of the song as I wanted.
