Composites rainbow halos and/or glint-like rays at locations where the Source
clip is brighter than the threshold.
Lower the threshold parameter to produce glares in more areas.
Use the Style menu to select different glare types.
Set the Glare Res parameter to 1/2 for faster rendering with slightly softer glares.
Use the Convolve option for smoother results, but possibly slower rendering.
Glares are best observed on dark images with a few bright spots.
In the Sapphire Lighting effects submenu.
Source: The current layer. The input clip that determines the glare locations and
Background: Defaults to None. The clip to combine the glares with. If no background is
given, the Source is also used as the Background.
Matte: Defaults to None. If provided, the source glare colors are
scaled by this input. A monochrome matte can be used to choose
a subset of Source areas that will generate glares. A color matte
can be used to selectively adjust the glare colors in different
regions. The matte is applied to the source before the glares are
generated so it will not clip the resulting glares.
Popup menu, Default: rainbow_rays.
The style of glare to apply. Custom glare types can also be
made, or existing types modified, by editing the "s_glares.text"
- rainbow_rays: rays with rainbow.
- rainbow_rays2: rays with larger rainbow.
- rays_60: cluster of 60 rays.
- rays_20: cluster of 20 rays.
- rays_16: cluster of 16 rays.
- rays_12_rand: 12 rays with random orientations.
- rays_6: cluster of 6 rays.
- rays_4: cluster of 4 rays.
- rays_4_ring: 4 rays with ring and glow.
- rays_multi: several clusters of rays together.
- rainbow_only: rainbow.
- rainbow2_only: larger rainbow.
- rainbow_double: 2 rainbows.
- round_coin: simple solid circle.
Popup menu, Default: NO.
Determines the method for applying the glares to the
- NO: by default, the center of each bright spot is found
and a glare is rendered at that location. In this mode, if there
are multiple moving bright spots that merge or separate, pops in the
glare locations can occur.
- YES: the convolve option smoothly adds glares for each
pixel of the source image above the threshold value. This gives a
different look which can be preferable. However, if there are many
bright areas needing glares, it can be unbearably slow, so in this
mode the processing times are estimated and very slow frames are
- Even if slow: use this option if you are sure you want to
convolve all the frames of a clip even if they might be slow to
- Brightness: Default: 1, Range: 0 or greater.
Scales the brightness of all the glares.
- Scale Colors: Default rgb: [1 1 1].
Scales the color of the glares. The colors and brightnesses
of the glares are also affected by the Source and Matte inputs.
- Saturation: Default: 1, Range: -2 to 8.
Scales the color saturation of the glare elements.
Increase for more intense colors. Set to 0 for monochrome glares.
- Threshold: Default: 0.8, Range: 0 to 1.
Glares are generated from locations in the source clip
that are brighter than this value. A value of 0.9 causes glares at
only the brightest spots. A value of 0 causes glares for every
- Threshold Add Color: Default rgb: [0 0 0].
This can be used to raise the threshold on a
specific color and thereby reduce the glares generated on areas of the
source clip containing that color.
- Threshold Blur: Default: 2, Range: 0 or greater.
Increase to smooth out the areas creating glares.
This can be used to eliminate glares generated from small speckles or
to simply soften the glares. Increasing this may put more highlights
below the threshold and darken the resulting glares, but you can
decrease the Threshold parameter to compensate.
- Size: Default: 72, Range: 0 or greater.
Scales the size of the glares.
- Rel Height: Default: 1, Range: 0 or greater.
Scales the vertical dimension of the glares, making
them elliptical instead of circular.
- Rotate: Default: 0, Range: any.
Rotates the ray elements of the glares, if any, in
- Glare Res:
Popup menu, Default: Full.
Selects the resolution factor for the glares. Higher
resolutions give sharper glares, lower resolutions give smoother
glares and faster processing. This 'Res' factor only affects the
glares: the background is still combined with the glares at full
- Full: Full resolution is used.
- 1/2: The glares are calculated at half resolution.
- 1/4: The glares are calculated at quarter resolution.
- Affect Alpha: Default: 1, Range: 0 or greater.
If this value is positive the output Alpha channel will
include some opacity from the glares. The maximum of the red, green,
and blue glare brightness is scaled by this value and combined with
the background Alpha at each pixel.
- Glare From Alpha: Default: 0, Range: 0 to 1.
Set to 1 to generate glares from the alpha channel
of the source input instead of the RGB channels. In this case the glares
will not pick up color from the source and will typically be brighter.
Values between 0 and 1 interpolate between using the RGB and the Alpha.
- Glare Under Source: Default: 0, Range: 0 to 1.
Set to 1 to composite the Source input over the glares.
- Source Opacity: Default: 1, Range: 0 to 1.
Scales the opacity of the Source input when
combined with the glares. This does not affect the generation
of the glares themselves.
- Bg Brightness: Default: 1, Range: 0 or greater.
Scales the brightness of the background. This parameter
only has an effect if the background input is provided, and is
visible due to a partially transparent Source image or a reduced Source
Opacity parameter value.
- Invert Matte: Check-box, Default: off.
If on, inverts the Matte input so the effect is applied
to areas where the Matte is black instead of white. This has no effect
unless the Matte input is provided.
- Expand Borders: Check-box, Default: off.
If enabled, transparent borders are added to the
input image before processing. This allows the result to include soft
edges beyond the original image size. When off, the effect only
occurs within the frame and the result will retain an edge
at the borders. This parameter does not appear in FCP or DF because
those applications don't support image expansion.
Popup menu, Default: Normal.
Determines the method used for dealing with
- All Opaque: Use this option to render slightly faster when
the input image is fully opaque with no transparency (alpha=1).
- Normal: Process opacity normally.
- As Premult: Process as if the image is already in
premultiplied form (colors have been scaled by opacity). This option
also renders slightly faster than Normal mode, but the results will
also be in premultiplied form, which is sometimes less correct.
- Show Size: Check-box, Default: off.
Turns on or off the screen user interface widget for
adjusting the Size and Rel Height parameters.This parameter only appears on AE and Premiere,
where on-screen widgets are supported.
