Tutorial Paper: Multilevel Compositing in the Digital Domain
Digital post-production is now a reality, but digital compositing equipment does not yet offer the features of an analog switcher. Digital recording equipment has much lower degradation than analog recording equipment, and it is possible to go through many generations and retain acceptable quality. Most compositing systems currently offered rely on this capability, and permit compositing of only one image layer at a time. This article examines the reasons for requiring multilayer compositing in analog suites, and suggests that the need exists also in the digital suite. An approach is described which offers capabilities equaling or exceeding those of traditional analog suites.
