Sound/Music

Sound is a very important element when making my film; the screens on computers or mobile phones aren't huge therefore the picture has less of an effect than it would if it was on a cinema screen. However, the sound is always going to be as loud as the computer or mobile speakers can go so I need to make sure it is good; this could be a major element that keeps my audience interested.
 
J-Cuts; This is whereby you lay in a couple of seconds of sound from one clip over the end of the one before to help the viewer follow the trailer.
Soundbridge; A soundbridge is similar to a J-Cut however the sound from one clip will follow on to the next and could follow on for many scenes. Similar to a J-Cut, its connects the frames together and helps the audience follow.

Types of Sound:
Sound is overall divided into two categories, this being Diegetic and Non Diegetic Sound.
Diegetic; Generated by things we can see in the picture. E.g. A dog or a person talking
Non Diegetic; Generated outside the picture. E.g. A voice over or music.

DIEGETIC:
Location Sound; this is sound that is in the shoot itself - it is often enhanced with sound effects.
Ambient Sound; this is any natural noise outside. Usually added to create realism.
Room Tone; this is any natural noise inside. Added to create realism also.
Dialogue; this an important part of diegetic sound, and depends on vocal delivery.
NON DIEGETIC:
Soundtrack; this is previously-recorded music chosen because of its fit to the rhythm, content and mood of a sequence. If a song, the lyrics may add meaning to the images.
Score; this is music specifically composed to accompany images. As well as enhancing mood and atmosphere, it can be used thematically - e.g. a character can be represented by a musical theme every time they appear, or the audience can be reminded of a situation every time a musical theme recurs (e.g. the 'shark theme' in JAWS).
