You can composite equirectangular imagery on top of other equirectangular imagery as long as you do not change its vertical position and scale. For example, Horizontal Squeeze or Wipe works, while a simple Picture-in-Picture effect looks distorted, because it scales both the vertical and horizontal dimensions of the image.Īlso consider compositing. Consider how a pixel’s vertical position affects its horizontal distortion once perspective is applied. The basic rule is that if an effect changes a pixel’s vertical position, it’s unlikely to work. These effects do not alter a pixel’s position enough to cause an issue. Three common effects used in equirectangular projection are Dissolves, Color (Lumetri), and Speed. For example, 160 by 90 degrees presents a 16:9 view window. Also note that these settings determine the aspect ratio of the view window. For example, using a value of 90 horizontal by 60 vertical degrees approximates an Oculus Rift headset 160 by 90 degrees simulates viewing within YouTube. The Monitor View fields allow you to control what portion of the sphere you view-where you can simulate different viewing experiences-while in the VR Video Display mode. Typically, you leave controls set at the full-sphere defaults of 360 horizontal by 180 vertical degrees. The Captured View describes what part of the sphere the video frame represents. When working with immersive video, think in degrees of view, in addition to pixel dimensions.
If you choose one of the stereoscopic layouts, you’re given a choice of a Stereoscopic View, either the Left or Right eye, along with a red/cyan anaglyph composite. Frame Layout lets you declare if your video is Monoscopic or Stereoscopic, the latter also allowing you to choose between an Over/Under or Side-by-Side layout.
