- Description
- The SI file format is associated with Softimage, a now-discontinued 3D graphics application developed by Autodesk. Originally designed for creating 3D models, animations, and visual effects, Softimage was widely used in the film, gaming, and advertising industries. SI files typically contain project data, including 3D models, textures, animations, and other related assets. Despite its discontinuation, the SI format and Softimage's tools remain influential in the 3D modeling and animation sectors.
- Based on HEVC (High-Efficiency Video Coding), the HEIF format is an image file container with one or multiple images and is the default image format for Apple Live Photos. It replaced the JPEG format as it's smaller in size and has lossless compression ensuring high-quality photos.
