EX-4D

About EX-4D

EX-4D is an open-source AI framework developed by the Pico/Bytedance team that converts a single 2D video into a controllable 4D experience. It enables users to explore videos from various camera angles with smooth transitions, thanks to its innovative Depth Watertight Mesh technology.

Review

EX-4D introduces an interesting approach to video manipulation by allowing dynamic camera control over standard footage. Its ability to maintain geometric consistency at extreme viewpoints sets it apart from traditional video editing tools. This makes it a promising option for those looking to enhance video interactivity without capturing footage from multiple angles.
