The LucasFilm Format (LFF) is a specialized file format that was developed by Lucasfilm Ltd., a prominent American film production company. It is primarily used for storing digital audio and video data, often related to visual effects, computer-generated imagery, and digital content production for movies. LFF files are designed to support high-quality multimedia content, ensuring that detailed textures, complex animations, and intricate sound designs are preserved during the production process. This format is part of the proprietary technologies used by Lucasfilm and its divisions, including Industrial Light & Magic (ILM), to create and manage digital content for their cinematic projects.
Image stored in the JPEG XR format, which was originally developed by Microsoft for Windows Media software; supports deep color images with 48-bit RGB; used for high-resolution professional image editing; also supports lossless and lossy compression.
