Editing - review

Once sounds have been recorded, and though there is still a vast amount of the project to go, it's important to put the animation and sound together and to review what stage you're at. Music must be edited, foley must be moved around so that it's timed better, more echo needs to be added in some areas to create depth, a floorboard needs to creak a little louder. All of these little subtitles have to be reviewed, considered and appropriately altered. This is an important stage as it adds real finess to a film and can be the difference between a film being realistic or a badly dubbed flop. If the sound of hammer dropping on the floor takes place 2 seconds after it actually occurs and sounds like a stone being thrown down a well, something isn't going to fit. There are a number of jobs for sound engineers and sound editors in the film, T.V. and animation industry. This website shows a number of small jobs looking for people to work on the sound for their respective films, video projects etc ... Albeit in America, it still gives a good idea of the kind of jobs available.

As you can see from one of my earlier posts, the editing -review stage takes place twice in the pipeline, this is important to ensure that any alterations to the animation are taken into consideration within the sound of the piece. For example if they've removed a section in which a character is punching a punch bag, it's no good keeping the sound of the punchbag in the file. A website produced by Channel 4 giving a tutorial on animation said this about the second part of the editing process. 

'Post-production sound editing primarily involves preparing the sound track for import into the video editing software, this may involve adjustments to the sequence or occurrence of particular sounds due to changes made in the Editing stage. Many sound changes may take place simply within the Video Editing software itself and may not require much, if any, changes to made within the Sound Editing software.'
