BCC Film Glow

Film Glow

Deprecated – replaced by BCC Fast Film Glow 

We recommend use of BCC Fast Film Glow instead of BCC Film Glow in BCC10 and higher.  The newer BCC Fast Film Glow is fully GPU accelerated using OpenCL and provides the same feature set but with much faster rendering.


The BCC Film Glow filter generates a traditional film glow look, where the frame is subjected to a strong light source causing the image to bloom.  A common use of the glow filter is to make the whites in an image appear to glow and the filter will do this at its default settings.  To generate that flash to white glow, you need only animate the Glow Intensity parameter from 0 to the maximum desired value.  The Glow Threshold control is very useful in adjusting which regions or the image will contribute to the glow based on the brightness ranges found in a particular source clip.  Setting the Threshold Color value to anything other than white will prevent pixels of the same color value from contributing to the glow.  Toggling between box and triangle blur types allows for interesting stylized variations on the glow look.


Parameter Controls

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.

Compare Mode

The BCC Compare Mode provides a convenient mechanism to compare the effect result with the original source layer. It provides several variations on basic split-screen views with the filtered clip placed next to the unedited original.

Avoid Clipping: (Available on in After Effects and Premiere.)  This feature enables the glow to expand beyond the edges of the filtered image, thereby generating an even glow out past the edges of the image.  Disabling the feature clips the glow with a soft falloff toward the edge of the filtered image.  Note that when Avoid Clipping is enabled, the Pixel Chooser is not available.

View: This four way pop-up is useful when setting up the filter:

  • Output This is the main result of the full  glow effect applied back over the input clip
  • Glow Displays just the generated glow prior to being applied back to the input clip via the apply modes.
  • Threshold Displays the intermediate result of the threshold setting
  • Threshold w Boost + Desat Displays the intermediate result of the Threshold with Boost and Glow Desaturation applied

Glow Intensity: Use to control the intensity of the glow result. Higher values yield a stronger glow with a total white image when this parameter is set to it’s highest value.

Glow Color: Used to set the color of the glow. Default is white.

Glow Radius: Use to set the radius over which the glow spreads to surrounding regions.

X Width: Independent control for the width of the glow.

Y Width: Independent control for the height of the glow.

Glow Desaturation: This function alters the glow result by adjusting the chroma values that are used for the input. At 0 the function has no effect on the result generating a traditional film glow, increasing the value in this parameter yields a result that looks colder and less saturated.

Glow Threshold: Used to set the pixel values that are affected by the glow – a setting of 0 will apply a glow to all of the pixels in the input clip, while a setting of 100 will not apply any glow to the image

Threshold Color: The RGB values of this color are added to the threshold slider value to make an independent threshold for each channel. (e.g. if this is set to pure blue, the blue channel is not glowed, regardless of the channel values or the threshold slider setting.)

Matte Layer: If a matte layer is selected, the alpha premultiplied RGB values of this layer are used as a matte, applied to the RGB Glow (before the blur) independently for each channel E.g. if a pixel in the matte layer is pure blue, the corresponding source pixel will only contribute to the blue channel before the glow is applied.

Matte Type: This pop-­up offers 6 channel options for the matte input:

  • Color – matte is based on the color values of the matte input
  • Color Inverted – inverted matte, based on the color values of the matte input
  • Luma ‐  matte is based on the luma values of the matte input
  • Luma Inverted – inverted matte, based on the color values ov the luma input Alpha – matte is based on the alpha values of the matte input
  • Alpha Inverted – inverted matte, based on the alpha values in the matte input

Blur Type pop-­up: This two way pop-­‐up offers the option of using a Box or a Triangle blur for the glow effect.

Triangle Blur Iterations: Use to set the number of times the triangle blur is applied to the glow. Higher values will generate a smoother glow but will increase render times.


RGB Independent Group

RGB Independent Glows: This checkbox enables independent scaling of the glow dimensions for R, G, and B.

Red Scale: Scales red glow uniformly.

Red Scale X: Scales red glow along horizontal axis.

Red Scale Y: Scales red glow along horizontal axis.

Green Scale: Scales green glow uniformly.

Green Scale X: Scales green glow along horizontal axis.

Green Scale Y: Scales green glow along horizontal axis.

Blue Scale: Scales blue glow uniformly.

Blue Scale X: Scales blue glow along horizontal axis.

Blue Scale Y: Scales blue glow along horizontal axis.


Glow From Alpha: The Glow From Alpha option generates the image glow from the alpha channel instead of or in addition to the color channels. The selection in the Glow From Alpha Mode determines how the alpha glow and the color channel glows are combined.

Glow Alpha Mode: This pop-­‐up is used to select how the alpha glow and  the color channel glows are combined. If it is set to Blend (the default) increasing glow from alpha decreases the impact of the RGB channels on the glow. If it is set the Add, the glow from each color channel is added to the alpha glow.

Glow Boost Alpha: Controls how much the spread of glow pixels caused by the blur boosts the alpha channel of non-­‐opaque pixels.

Glow Under Source: Allows you to animate between compositing the glow over the source (default setting), under the source (setting of 0) or anything in-­‐between.

Source Opacity: The opacity of the source image that is composited with the glow. At a setting of zero only the glow is rendered.

Apply Mode: This pop-­‐up is used to set the apply mode that the filter uses to composite the glow over the input image. The default apply mode is “Screen” and there are 27 different apply modes to select from.

Apply Mix: Use to blend between a normal apply mode and the user selected apply mode.

Mix with Original: Used to blend the filter effect back with the unfiltered input image.


Motion Tracker

The BCC Motion Tracker allows you to track the motion of an object, then use the motion path to drive other geometric properties of the effect without the need for keyframing.

For more information on the Motion Tracker, Click Here.



The BCC PixelChooser provides simple, built-in masking of the effect result.  The PixelChooser is generally used to select a portion of the image and restrict an effect to just the selected area while maintaining the original image content in unselected regions.  The selection can be based on geometric shapes or on the image’s luma/color properties.

For more information on the PixelChooser, Click Here.

Note that when Avoid Clipping is enabled the Pixel Chooser is unavailable in Film Glow.


Beat Reactor

The BCC Beat Reactor is an animation control suite which drives effect properties based on the contents of an audio track. This lets you seamlessly tie visual FX to an audio soundtrack without the need for ANY manual keyframing.
