Comp means “Compositing visual elements in video or Film”
Compositing in VFX and CGI as a job title can leave your work open to a large variety of skill sets depending on where you work and what is needed. For example I’ve seen the compositor asked to rely on their skills in lighting, 3d, rendering, modeling, color correction, editing, green screening, camera work, and much more in order to complete their shot. It’s a huge task to complete a shot and compositors in some cases become generalists who enact the vision of the director in the last moments of post production using a bag of tricks that overlaps many other areas of post production.
“Compositing is the combining of visual elements from separate sources into single images, often to create the illusion that all those elements are parts of the same scene. Live-action shooting for compositing is variously called “chroma key”, “blue screen”, “green screen” and other names. Today, most, though not all, compositing is achieved through digital image manipulation. Pre-digital compositing techniques, however, go back as far as the trick films of Georges Méliès in the late 19th century; and some are still in use.”
Past the point of explaining all of the whats and hows of compositing………… my focus now turns to showing you some of my work in this area. I’ve worked in various areas of VFX in film and video for several studios. The film work was mainly 3D / CG and the compositing was easy. The video work I’ve done for corporations such as Sprint, Kansas City Chiefs football, US Army, Marines and other large companies was more intense and integrated live action video and VFX on small scales with short deadlines. Essentially compositing 3D and compositing to make things that were not real visually illustrate the companies proposed objective.
