CubeVi SpatialHub is an online video hub like YouTube, but designed specifically for spatial videos such as SBS (side-by-side) videos. Users can upload their own SBS videos, and anyone with a CubeVi display can watch them directly in 3D.

A side-by-side (SBS) video is a format where the left-eye and right-eye images for 3D content are placed next to each other in a single frame, usually with the left-eye view on the left and the right-eye view on the right.

The video often looks horizontally squished when viewed normally, because each half of the frame contains a full image. A 3D display, VR headset, or compatible software then stretches and routes each half to the correct eye, creating a sense of depth.

If you own a CubeVi display, you can access SpatialHub directly inside Cubestage. The display will automatically recognize the video format and play it in 3D.

You can convert 2D videos to 3D using our built-in tools or third-party tools like Owl 3D. These tools accept standard video formats (MP4 or MOV) and output SBS-enabled videos that you can watch in 3D on a CubeVi display.

Most SBS creators assume that VR videos, 3D movies, or iPhone Spatial Videos should look even better on a spatial display. But desktop 3D monitors operate in a completely different perceptual scale: instead of placing viewers inside a giant world, they create a miniature world in front of them. This single shift explains why many existing 3D formats look wrong, and why AI-generated or 3DGS-based SBS content often looks far more natural. This article breaks down that hidden geometry—so creators can design SBS videos that truly shine on spatial displays.
