In a movie, computer generated imagery can take anywhere from a few weeks to several years to complete. For small scenes or limited effects, CGI work may take 2–3 months. In a large CGI film or a movie with heavy visual effects, the process can take 1–3 years. The time depends on concept design, 3D modeling, texturing, animation, lighting, simulation, rendering, and final compositing. When computer generated imagery in film is used for realistic characters, creatures, or large environments, more time is required because every movement, texture, and light interaction must look natural. To understand what is CGI in movies, it is the use of computers to create or enhance visuals that are difficult, costly, or impossible to shoot in real life, such as fantasy worlds, explosions, or digital characters.
Conclusion:
The time needed for computer generated imageryin movies depends on scene complexity, realism level, and team size. Simple CGI may take weeks, while a full-scale CGI film can take years to achieve high-quality, realistic results that blend smoothly with live-action footage.
