BCC Grunge

BCCGrungeHelpDoc

The BCC Grunge filter combines procedural algorithmic methods with real photographic image textures that can be used on titles to create unique grungy, degraded, torn-up, or melting looks.  These same effects can be applied to background plates.

Function

Presets and Common Controls

BCC 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™.

BCC filters also include common controls that configure global effect preferences and other host-specific effect settings.

For more information about working with presets and other common controls, Click Here.

 

Load / Save Preset Mechanism

The built-in load save mechanism is used to access the factory installed or user generated presets.

Use Texture:  Enable to composite a selected texture image over the input. The texture image file is selected from the Textures pop-up.  When disabled the other Grunge operations are applied to the original source image instead of to the texture-source combination.

Textures:  Pop-up menu for selecting from installed textures.  This filter includes a series of factory installed photographic textures that can be used to create the grunge look. Additional texture files may be added to the filter by placing them into the following directory:

Mac : Macintosh HD/Library/Application Support/Grunge Texture/
Win : C:\Program Files\Boris FX,Inc\Grunge Texture\

Images added to this directory will appear in the filter Textures menu the next time the host application is launched.

This filter includes textures that were created by the following photographers:

Apply Group

A built-in set of Apply modes can be used to blend the selected texture with the filtered source input.  The selected apply mode can be mixed back with the normal apply mode to create unique looks.

Apply Mode:  Menu containing a listing of 27 different apply modes.

Apply Mix:  Specifies the amount of blending between the selected apply mode and the normal mode.

 

Color Group

Use to refine the basic color properties of the  source+texture combination.

Color On:  Enable/Disable the color correction features and access the feature’s parameter controls.

Brightness:  Positive values brighten the image, negative values darken the image.

Contrast:  Positive values increase contrast in the image, negative values decrease contrast.

Saturation:  Positive values increase saturation in the image, negative values decrease saturation.

 Tint Color:  Set the tint color.

 Tint Amount:  Use to set the amount of color tinting that is applied to the image.

 

Transformation Group

The controls in this group modify the geometric transforms applied just to the texture and do not affect the geometry of the filtered source clip.  Note that when geometric transformations cause the texture to fail to fill the clip region, the texture is seamlessly tiled to ensure the entire clip is covered.

Position XY:  Use to set the position of the texture along the XY axis.

Rotation:  Use to rotate the image around the Z axis.

Scale Lock to X:  When checked, locks the Y scale transform to the X scale transform values.

Scale X:  Use to scale the texture along the X axis (or XY if Scale Lock to X is enabled).

Scale Y:  Use to scale the image along the Y axis independently of the X axis.

Opacity:  Use to set the opacity of the texture.

Use Source Alpha:  When checked, restricts the filter result to the confines of the image’s alpha channel.

 

Displacement Map Group

The controls in this group are used to distort the filter result and can, for instance, create animated ripped or torn textures. The Displacement Map distortion works by using the channel values in a map layer to specify how much to distort the matching pixel in the main layer.   By default, the selected image from the Textures group is used as the reference map to distort the image, but any layer from the host can be used as the basis for image distortion.

Displacement Map on:  Enable/Disable this feature and access the feature’s parameter controls.

Source:  Specify which image is modified by the distortion.

  • Composited:  Apply to the combined source + texture result.
  • Texture: Apply just to the texture.
  • Source:  Apply just to the original source clip.

Map:  Specify which image is used as the reference map which defines the amount/direction of the distortion.

  • Composited:  The combined source + texture result defines the distortion map.
  • Texture:  The texture image alone defines the distortion map
  • Source:  The source clip alone defines the distortion map.
  • Layer:  An alternate host layer defines the distortion map.

Layer:  When the Map is set to use an alternate host layer, this menu defines which host layer will be used as the distortion map.

Lock To Scale X:  When checked, locks the Layer Y scale transform to the Layer X scale transform values.

Layer Scale X:  Use to scale the displacement map layer along the X axis (or XY if Scale Lock to X is enabled).

Layer Scale Y:  Use to scale the displacement map layer along the Y axis.

Layer Pattern:  Determines how the displacement map layer edge regions are handled if the scaled map layer is smaller than the full frame.

  • None:  No edge handling is applied and regions outside the layer map boundaries are treated as empty.
  • Tile:  The layer map is tiled to fill in the empty regions.
  • Mirror:  The layer map is mirrored to fill in the empty regions which ensures smooth transitions along the edge boundaries.

Channel X:  Specifies which channel in the displacement map is used to define the distortion amount in the X direction.

Amount X:  The magnitude of the distortion in the X direction.

Channel Y:  Specifies which channel in the displacement map is used to define the distortion amount in the Y direction.

Amount Y:  The magnitude of the distortion in the Y direction.

Edge Type:  Controls the handling of distorted regions that extend outside the main image edges.

  • None:  No special edge treatment is applied and regions outside the image boundary are treated as transparent.
  • Repeat:  Boundary pixels are repeated off the edge which can be used to ensure that transparency does not creep into the final result when applying Grunge to full frame footage (as opposed to titles or other alpha objects).

 

Bump Map Group

The controls in this group add a 3D bump map look to the result.  The bump can be set to use the combination of the source input / texture map composite or you can use any layer from the timeline.

Bump Map on:  Enable/Disable this feature and access the features parameter controls.

From Layer:  When set to None the source + texture combination is used to define the bump map.  When set to an alternate host layer, that layer will then define the bump map.

Lock To Scale X:  When checked, locks the Layer Y scale transform to the Layer X scale transform values.

Layer Scale X:  Use to scale the bum map layer along the X axis (or XY if Scale Lock to X is enabled).

Layer Scale Y:  Use to scale the bump map layer along the Y axis.

Layer Pattern:  Determines how the bump map layer edge regions are handled if the scaled map layer is smaller than the full frame.

  • None:  No edge handling is applied and regions outside the layer map boundaries are treated as empty.
  • Tile:  The layer map is tiled to fill in the empty regions.
  • Mirror:  The layer map is mirrored to fill in the empty regions which ensures smooth transitions along the edge boundaries.

Use Alpha:  Enable to use the source image’s alpha channel as a mask for the filter, so the texture appears only in the opaque regions of the source. If this option is deselected, the source image’s alpha channel is ignored.

Height:  Determines the height of the bump map used to create the texture of the bricks.

Smoothness:  Adjusts the amount of blur applied to the bump map. Higher values produce more blur, which tends to reduce the amount of detail and noise in the filtered image.

Light Type:  Determines the type of light source.

  • Point: combines both focused (specular) and diffuse light. You can use this Light Type to create the appearance of a shiny surface lit by a point light source.
  • Distance: creates a non-directional infinitely distant diffuse light, similar to sunlight.
  • Spot: creates the look of a traditional theatrical spotlight. Spot creates a small spot of intense light whose falloff can vary.

Light XY:  Controls position the light source in space by moving the light parallel to the image plane along the X and Y axes.

Light Z:  Positions the depth of the light source relative to the image plane. A value of 100 places the light one source width above the image plane. Light Z can be negative, which places the light behind the image plane. If Light Z is negative, the light is seen only if the object is rotated or displaced so that all or part of it is behind the light source (that is, the light source always points in toward the object, never out at the viewer).

Light Intensity:  Controls the intensity of the light.

Light Color:  Controls determine the color of the light.

Spot XY:  Controls set the X and Y coordinates for the point at which the spotlight is aimed. Unlike the X and Y Light controls (under the Light Type menu), adjusting the Spot parameters does not change the shape of the light.

Spotlight Angle:  Sets the angle of the light. This is analogous to focusing the light. Decreasing values create a smaller, more focused light.

Spotlight Falloff:  Controls the relative softness of the edges of the lit region. Leave Spotlight Falloff at its default setting if you prefer a soft edge, or decrease this value to harden the edges of the lit region. Spotlight Falloff removes light from the edges of the lit region. To maintain the size of the region while softening the edges, you need to increase Spotlight Angle accordingly.

Use Texture Color:  Select to use the color values from the underlying track to which the filter is applied. Deselect this checkbox to use the luminance values only. When this checkbox is deselected, the Color control below sets the color that is used with the luminance values.

Color:  When Use Texture Color is deselected, this sets the color that is used with the luminance values.

White in Specular:  Increases the amount of white in the specular light. Increasing this value can create a more metallic surface effect. This parameter is only useful when Specular Intensity has a value greater than 0.

Ambient Intensity:  Adjusts the total amount of diffuse light on the image. The default setting of 100 does not add or subtract ambient light from the source image. Decreasing this setting makes the image darker before the other lights are applied. Ambient light illuminates or darkens the image evenly, and is unaffected by any other lighting parameters.

Diffuse Intensity:  Determines the amount of non-directional diffuse light applied to the object. Increasing Diffuse Intensity brightens the object uniformly.

Specular Intensity:  Simulates lighting a glossy surface from a point source, creating a small spot of intense light whose falloff can vary. Increasing this value adds reflected light to the surface.

Shininess:  Controls the rate at which the Specular light falls off from the center of the lit region. A higher Shininess value creates a more concentrated highlight, simulating a shiny, highly reflective surface. A lower Shininess value spreads light more evenly throughout the lit region, simulating a rougher, less reflective surface.

 

Erosion Group

The parameters in this group enable you to completely or partially erode the texture and / or shape of the source over time.  The erosion pattern is defined by an erosion map layer which can be taken from the source/texture or from a separate host layer.

  • Composited:  The combined source + texture result defines the erosion pattern.
  • Texture:  The texture image alone defines the erosion pattern.
  • Source:  The source clip alone defines the erosion pattern.
  • Layer:  An alternate host layer defines the erosion pattern.

Layer:  When the Map is set to use an alternate host layer, this menu defines which host layer will be used as the erosion pattern map.

Lock To Scale X:  When checked this locks the Layer Y scale transform to the Layer X scale transform values.

Layer Scale X:  Use to scale the erosion pattern map layer along the X axis (or XY if Scale Lock to X is enabled).

Layer Scale Y:  Use to scale the erosion pattern map layer along the Y axis.

Layer Pattern:  Determines how the erosion pattern map layer edge regions are handled if the scaled map layer is smaller than the full frame.

  • None:  No edge handling is applied and regions outside the layer map boundaries are treated as empty.
  • Tile:  The layer map is tiled to fill in the empty regions.
  • Mirror:  The layer map is mirrored to fill in the empty regions which ensures smooth transitions along the edge boundaries.

Channel:  Specifies which channel in the erosion pattern map is used to define the erosion amount.

Amount:  The amount of erosion.  It can be animated to 100 to make the image disappear completely.

Smoothness:  Defines the smoothness of the transition between eroded and non-eroded regions.

Softness:  Softens the erosion pattern map to create smoother and less abrupt changes in the erosion pattern across the image.

Inverse:  Inverts the erosion pattern map so the erosion progresses in the opposite order – i.e. from light to dark parts of the map instead of dark to light.

Max Length: Specify the maximum length of the scratches as a percentage of the image height.

Random Seed:  Determines which value is input to the random number generator used for generating the random pattern of scratches.  Adjust this value when you like the overall effect but want to re-randomize the scratch lines.

 

Orbs Group

The orbs group is used to add randomized spots into the image, similar to the effect of water spots on the surface of a camera lens.

Orbs On:  Enable/Disable this feature and access the feature’s parameter controls.

Grain Group

This feature uses procedural methods to emulate film grain.

Grain On:  Enable/Disable this feature and access the feature’s parameter controls.
