Post Production Supervisors are responsible for the post production process, during which they maintain clarity of information and good channels of communication between the producer, editor, supervising sound editor, the facilities companies (such as film labs, CGI studios and negative cutters) and the production accountant. Although this is not a creative role, it is pivotal in ensuring that the film's post production budget is manageable and achievable, and that all deadlines are met. Because large amounts of money are involved, and most of a film's budget is spent during production, the post production period can often be difficult and challenging.
The role of the Post Production Supervisor varies according to the type of film and the budget. On big budget films using complex CGI (Computer Generated Images), they start work during pre-production, liaising with the CGI Company and ensuring that the producer is aware of all the creative and budgetary considerations and how they may impact on the post production period. On smaller budget films they also advise about any limits that may need to be applied to the shoot, as well as providing an overall picture of what can be realistically achieved in post production. Most Post Production Supervisors also liaise with the editor and producer (and sometimes the director), about the hiring of post production personnel (sound editors, titles designers, mixers, etc).
