# Video

The dome features 6 projectors stitched together, supporting 8k (8192 × 8192 px) or 4K (4096 x 4096 px) fulldome video. For quicker rendering, 1920 x 1920 px suffices. The dome can also do equirectangular 2:1 content which it reframes to fulldome 1:1. All fulldome files are essentially a square with a circular image. Stereoscopic is side by side and similar to the [VR180](https://360labs.net/blog/vr-video-formats-explained) format.

You can test footage yourself in After Effects. Use effect [VR converter > To Fulldome](https://www.youtube.com/watch?v=xM_PDDpaD_Y\&themeRefresh=1).
