Overview of the MPEG V3C standard for immersive video coding

A volumetric video consists of a sequence of frames, where each frame is a static 3D representation of a real-world object or scene capture at a different point in time.

However, such contents can consume significant bandwidth. Compression of volumetric video is required to obtain data rates and files sizes that are economically viable in the industry. Standardization is required to ensure interoperability.

The Visual Volumetric Video-based Coding (V3C) standard specified by the MPEG group defines a generic mechanism for coding volumetric video and can be used by applications targeting different types of volumetric content, such as point clouds, immersive video with depth or transparency of visual volumetric frames.
