Lens Effects Gradients Video Post toolbar > Add Image Filter Event > Choose Lens Effects Highlight from Filter Plug-In list > Setup > Gradients tab A gradient is a smooth linear transition from one color or brightness to another, as shown below. Lens Effects use gradients to control aspects of the lens flares, such as colors and transparency. Lens Effects use several gradient types on page 6907. Lens Effects Gradients are always interpreted from left to right. Gradient Flags Gradients use Flags to indicate points along the gradient bar where you want different colors or brightness values to be. The colors between the flags are interpolated automatically by Lens Effects. Each Gradient inside Lens Effects can contain up to 100 flags. The current flag is highlighted and green. The position number above the gradient bar indicates the position of the current flag, in relation to the overall length of the gradient. A gradient always has non-moveable start and end flags. You can add up to 98 intermediate flags to alter the overall appearance of your gradients. You can also change the color or brightness of the end flags to suit your needs. When you place two gradient flags on top of one another, you create a sharp break in the gradient. When a third flag is placed on top of the second flag, a sharp edge appears in the gradient. WARNING When you animate Lens Effects parameters, this creates pointers into the actual scene, so Lens Effects animation is lost if you save the Video Post queue in a VPX file on page 8165. To preserve the animation, save the Video Post data, including Lens Effects animation, in the MAX file. 6902 | Chapter 22 Video Post
