Planning - Sound Effects

We originally planned to have 2 sound effects in order to compliment our trailer as we did not feel the soundtrack alone would be enough. We wanted one when the ghost disappears and one at the end of the trailer to end emphatically. We chose 'crashing metal' as we believed it would have the desired emphatic effect. However, when placed during the trailer on the scene where the spirit disappears it clashed too boldly with the music therefore we were not able to include this. The use of this sound effect at the end of the trailer was effective though. It allows us to cut the music off ending it cleanly with one noise.
