Student Filmmakers 360/VR Series- Using Mettle SkyBox Transitions 2


There is a tremendous surge in 360 VR Video as a professional format. The demand for content is growing daily but content creators need good information and accurate “How to” guides to navigate this very different visual space. I will be posting a continuing series of these helpful stories to inform and help you get into the 360 VR Immersive Video technology.

The magic makers at Mettle have released some new tools to help us 360 Videographers perform our magic. The new drag and drop seamless transitions are a valuable addition to the other 360 transitions already available. The new set supports the Equirectangular format, mono 2:1 or even 3D Stereo 1:1 Over-under.

Let’s take a look at what is included and how they look in action.

Chroma Leaks:

  • Change the Strength of the Vertical and Horizontal length of the Chroma leaks separately.
  • Adjust Leak angle to change the Rotation of the leaks.
  • Decrease Luma Threshold to effect more pixels in the image. The higher the threshold, the fewer pixels affected.
  • Adjust Leak Brightness and Saturation to effect how bright and saturated the Chroma leaks.
  • Change the Blend factor to adjust how the Chroma Leaks blend into your footage. The smaller the value, the less of a blend.
  • View Adjustments by toggling on VR Display mode or viewing in Skybox VR Player.

Light Leaks:

  • Adjust the Base Leak Hue to decide the initial color of the Light Leak. See this clearly with a lower Spectrum Width.
  • To add more colors from the Base color/hue increase the Spectrum Width. “0” has no color variations from the Base hue while 100 has several.
  • Lower Leak Intensity to effect the blend of the Light Leaks over your Equirectangular footage.
  • Adjust Leak Exposure to affect the gamma (midtones) of the light leaks.
  • Adjust Dissolve Length to affect how the light leaks dissolve into one another.
  • Change Point of Rotation to alter the point of the Rotation Angle will start from across your Equirectangular footage.
  • The Rotation Angle rotates your light leaks around the Point of Rotation.
  • View Point of Rotation adjustments by toggling on VR Display mode or viewing in Skybox VR Player.
  • Random Seed will randomize several of the above-listed parameters. This is a great way to explore variations over the entire light leak.

Light Rays:

  • Change the Start and End Point of Light Rays to determine where the Rays start and end.
  • The Start and Endpoint parameters have on-screen controls in the program Monitor.
  • Inverse the direction of the rays by clicking the empty box to enable it.
  • Clicking the box next to Follow Start Point will have the rays ignore the End Point value.
  • Adjust Luma Threshold to determine how many bright pixels are influenced. The higher the value, the fewer pixels affected.
  • Enable Use Tint Color to have your Rays tinted with the color you select under Tint Color.
  • Adjust Exposure to control the overall brightness of your rays.
  • Adjust Dissolve Length to manipulate the expansion of the rays dissolve.
  • View Adjustments by toggling on VR Display mode or viewing in Skybox VR Player.

Spherical Blur:

  • Change Point of Interest to Change region the Spherical Blur appears across equirectangular footage
  • View Point of Interest Change by toggling on VR Display mode or viewing in Skybox VR Player
  • Use Blur Strength to increase or decrease the amount of Blur
  • Use Exposure to effect gamma as well as blur the image during the transition
  • Add additional rotation animation during the transition to the outgoing or incoming clip
