Fixing the end!

The only thing now left to do in terms of sound, is fixing the end of the sound to fade out rather than just cut out at an awkward time. To do this, I had to take the sound from the climax before the 'COMING SOON' and repeat it at the end. To do this, I split the sound at the climaxed part and then copied and pasted it to the end of the trailer.

I then took another section of the music in the same way and to fade the climaxed bit into, so that the music didn't cut out too abruptly. 

The last thing that I needed to do was fade out the end completely into silence. I accidentally went about this the long way, but still came out with the same result. To do this I took the second section that I pasted and muted the sound completely, I then dragged it over (faded it into) the climaxed bit before. 

The silenced bit, although at the opposite extreme, still made the trailer cut out too abruptly. Therefore, I very slightly increased the decibels one more time to get the effect that I wanted. 

This proved successful in getting the fading out that I wanted at the end.
