For example, if Map Black Level is set to 50, all pixels with a value of 50 or less output to a value of 0. All pixels whose value is lower than the Map Black Level value become pure black. Map Black Level sets the channel values of the map that are output as pure black. This is particularly appropriate for a displacement map, which can severely distort areas of the image where the Map Layer changes rapidly. Increasing Blur Threshold blurs parts of the image with rapid changes in color without blurring subtle details. After the Map Layer is blurred, the blurred track is compared to the original Map Layer, and the color change for each channel is reduced by a relative amount. Blur Threshold softens the Map Layer before computing the displacements. Increasing Pre Blur can help eliminate sharp edges in the map to create a smoother effect.ĭisplacement filters often look rough if the Map Layer is high-contrast or has sharp edges. Pre Blur applies a blur to the Map Layer. The Map parameters control the appearance of the map used to distort the source image. You can also try using a title or logo to create a displacement as shown in the example at right. Luma gradients also make good Map Layers. Note: You can use the Noise Map filter to create auto-animated noise patterns that create a continuously flowing displacement effect.Pixels whose map alpha is 0 are not displaced. Note: If the Map Layer is partly transparent, the displacement amount is scaled by its alpha values.The Map Layer menu determines which clip layer in the timeline is used to create the distortions in the source image.

Vegas Pro Workflow Tip: To use the Light Wrap feature in Vegas Pro you must apply the filter in Custom Composite Mode.Selecting the Process Alpha Channel Only checkbox allows you to distort the alpha channel without changing the underlying colors. This filter creates a distorted version of the source whose distorted regions correspond to the luma or color channel of the Map Layer’s media.īCC filters come with a library of factory installed presets plus the ability to create your own custom presets and preview them with the BCC FX Browser™.īCC filters also include common controls that configure global effect preferences and other host-specific effect settings.įor more information about working with presets and other common controls, Click Here. The BCC Displacement Map filter uses the luminance or color information from an alternate video or still image track (the Map Layer) to displace the pixels in the source image horizontally and vertically.
