These tools are designed specifically for working with 360° video.
360° Video Transform
On 360° video, this can be applied to adjust the position of the video layer without losing its wraparound appearance. It can also be used effectively on wraparound environment maps.
Applying this to an ordinary layer will create distorted, unusual results.
360° Video Viewer
Apply this effect to a 360° video layer to wrap the layer onto a spherical shape for viewing. This wraps the selected layer onto a spherical shape.
When placed as the bottom layer in a 3D composite shot, this creates a convincing, wrap-around background for 3D shots. Examples would be a sky background for a cityscape or plane shot, or a space nebula for a spaceship fly-by.
The environment map viewer will automatically update as the camera is panned in all directions.
