Light Bender

What it does: Light Bender transitions between two clips while radiating shifting, curved flares from highlights in the image.

How to use it: First prepare the light source. This is the part of the video image from which the light flares should shine. Adjust the Source parameters to isolate the portion of the picture that will source the light. Next, design the light behavior with the Light control group. Finally, set the Blend controls to adjust how your clips transition between each other.

  • The Source group sets up the initial intensity of the light source:
  • Color sets the color of the light source. Typically, this is white, for a bright light. However, it can be any color, light or dark. Colors close in brightness and hue to the chosen color radiate light rays even if that color is dark. Examples are a white light, blue sky, or a bright red flower.
  • Sensitivity sets the strength of the light source. As the sensitivity is increased, more and more of the image becomes part of the glow source.
  • The Light group sets up the light behavior:
  • Color sets the actual color of the light. Use the color dropper to select a color directly from the video. Or, click on the color swatch to create or edit the color directly.
  • Blend determines the blend of the light color and original colors.
  • Blur adjusts how much the light flares blur the original image.
  • Skew sets the initial angle of the light flares.
  • Center sets the point around which the light flares rotate.
  • Rotation adjusts how fast the light flares move and which direction they are moving in.
  • The Blend group controls how the first and second clips transition between each other:
  • Liquify adds water-like ripples to the transition. Positive values make the image ripple outward towards the screen, and negative values make it shrink backward.
  • Light adjusts the strength of the light flares. Use this together with Blur to control how visible the light flares are.
  • Tempo sets the speed at which the effect changes the image. For a sudden change, set the Tempo high. For a gradual change, set it low.
  • Cross Fade sets the percentage of the transition that includes a cross fade of the image from the first to second clip. Turn down Cross Fade for an abrupt switch between images. Turn it up for an increasingly gradual mix.
