Working with AVX Plug-Ins

Third-party plug-in effects are compatible with the Avid Visual Extensions (AVX) standard. AVX is a cross-platform software architecture designed to allow software effect modules to be dynamically linked with a host application such as an Avid application.

Some of the effects that are supplied with your Avid editing application are AVX plug-in effects, for example, the Illusion FX category of effects. The exact set of Avid-supplied AVX plug-in effects varies depending on the model of your Avid editing application.

 

After you install third-party plug-ins, the effects appear in the Effect Palette in their own category (usually the name of the plug-in vendor). Individual effects each have a plug-in icon. The plug-in icon also appears in the Timeline when you have applied a third-party plug-in effect. After you create an effect, you can save it as an effect template and reapply the template to other transitions or segments in your sequence. Effect templates also appear in a special section at the bottom of the Effect Palette.

Plug In Sample :

SAPHIRE PLUG INS

Sapphire Plug-ins version 2.0 is a package of image processing and synthesis effects for use with Avid and compatible products.

It includes 178 plug-ins, each with many options and parameters which can be adjusted and animated for an unlimited range of results.

 

  1. 1.       Sapphire Distort

Warps the source input clip using the gradient of the Lens input clip. This can generate optical glass-like effects as if the source clip were being viewed through an arbitrarily shaped lens. It is best demonstrated when the lens image contains just a few bold shapes or a simple texture.

In the Sapphire Distort effects submenu.

Inputs:

Source:  The current layer.   The clip to be processed.

Lens:  Defaults to None.   Distorts the source using the brightness values of this input clip.

Matte:  Defaults to None.   If provided, the amount of lens distortion is scaled by this input, so the Source is unaffected where the Matte is black. This input can be affected using the Blur Matte, Invert Matte, or Matte Use parameters.

        
 

 

Parameters:

Amount:   Default: 1,  Range: any.
The severity of the lens distortions. Make negative to invert the direction of the distortions.

Fine:   Check-box,  Default: off.
If enabled, the warping amount is reduced by a factor of 100. This mode is meant to allow subtle expansion or contraction of the source image near the edges of its matte given as the Lens input.

Blur Lens:   Default: 36,  Range: 0 or greater.
Smooths out the edges in the lens image by this amount before using it.

Rotate Warp Dir:   Default: 0,  Range: any.
Rotates the warping direction by this many degrees. If non-zero, this can add some unusual twisting effects to the lens distortion.

Wrap:   X & Y,  Popup menu,  Default: [Reflect Reflect].
Determines the method for accessing outside the borders of the source image.

No:  gives black beyond the borders.

Tile:  repeats a copy of the image.

Reflect:  repeats a mirrored copy. Edges are often less visible with this method.

Filter:   Check-box,  Default: on.
If enabled, the image is adaptively filtered when it is resampled. This gives a better quality result when parts of the image are warped smaller.

Blur Matte:   Default: 0,  Range: 0 or greater.
Blurs the Matte input by this amount before using. This can provide a smoother transition between the matted and unmatted areas. It has no effect unless the Matte input is provided.

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.

Matte Use:   Popup menu,  Default: Luma.
Determines how the Matte input channels are used to make a monochrome matte.

Luma:  the luminance of the RGB channels is used.

Alpha:  only the Alpha channel is used.

Opacity:   Popup menu,  Default: Normal.
Determines the method used for dealing with opacity/transparency.

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.

 

  1. 2.       Sapphire EdgeRays

Generates beams of light emitting from the edges of an input clip. You can provide a Matte input to selectively scale the colors of the rays. If Matte Type is set to Color, you can also use the Matte input to colorize the rays differently in different regions. Set the Rays Res parameter to 1/2 for faster rendering with slightly softer rays.

In the Sapphire Lighting effects submenu.

Inputs:

Source:  The current layer.   The clip to be processed.

Background:  Defaults to None.   The clip to use as background.

Matte:  Defaults to None.   If provided, the ray colors are scaled by this input. A monochrome matte can be used to choose a subset of areas that will generate rays. If the Matte Type is set to Color, a color matte input can be used to selectively adjust the ray colors in different regions. This input can optionally be blurred or inverted using the Blur Matte or Invert Matte parameters.

        
 

 

Parameters:

Center:   X & Y,   Default: [360 243],  Range: any.
The location from which the rays beam outwards.

Rays Length:   Default: 0.25,  Range: -5 to 1.
The length of the rays. A length of 1.0 actually gives rays that continue forever, although though they may still fade out as they go. To make the rays look longer you can also increase the Rel Outer Bright parameter. If Rays Length is negative the rays can beam inwards instead of outwards. Note that processing times increase for longer rays.

Rays Brightness:   Default: 2,  Range: 0 or greater.
Scales the brightness of the ray beams.

Rays Color:   Default rgb: [1 1 1].
Scales the color of the ray beams.

Bias Outer Bright:   Default: 0,  Range: 0 to 1.
Determines the variable amount of brightness along the rays. This is normally near 0 so the rays fade away at their outer ends, 0.5 causes equal brightness along the rays, and 1.0 causes maximum brightness at the ends.

Rays Res:   Popup menu,  Default: Full.
Selects the resolution factor for the rays. Higher resolutions give sharper rays, lower resolutions give smoother rays and faster processing. This ‘Res’ factor only affects the rays: the background is still combined with the rays at full resolution.

Full:  Full resolution is used.

1/2:  The rays are calculated at half resolution.

1/4:  The rays are calculated at quarter resolution.

Show:   Popup menu,  Default: Result.
Selects between output options.

Result:  outputs the rays over the Background.

Edges:  outputs only the edge image. This can useful during the adjustment of the edge or shimmer parameters.

Edge Thickness:   Default: 4,  Range: 0 or greater.
The thickness of the edges which generate the rays.

Edge Brightness:   Default: 1,  Range: 0 or greater.
Scales the brightness of the edges which generate the rays.

Edge Subpixel:   Check-box,  Default: off.
Enables subpixel Edge Thickness amounts. Turn this on you are animating Edge Thickness or if you want finer control of small values.

Shimmer Amp:   Default: 0.5,  Range: 0 or greater.
Modulates the ray source image with this amount of grain texture to give the rays a shimmering look.

Shimmer Freq:   Default: 40,  Range: 0.1 or greater.
The frequency of the shimmer texture. Increase for a finer grained shimmer effect, decrease for softer grain. This has no effect unless Shimmer Amp is positive.

Shimmer Seed:   Default: 0.123,  Range: 0 or greater.
Used to initialize the random number generator for the shimmer texture. The actual seed value is not significant, but different seeds give different results and the same value should give a repeatable result.

Shimmer Shift:   X & Y,   Default: [0 0],  Range: any.
Translation of the shimmer texture. This has no effect unless Shimmer Amp is positive.

Shimmer Speed:   X & Y,   Default: [0 0],  Range: any.
Translation speed of the shimmer texture. If non-zero, the shimmering is automatically animated to shift at this rate.

Affect Alpha:   Default: 1,  Range: 0 or greater.
If this value is positive the output Alpha channel will include some opacity from the rays. The maximum of the red, green, and blue ray brightness is scaled by this value and combined with the background Alpha at each pixel.

Rays From Alpha:   Default: 0,  Range: 0 to 1.
Set to 1 to generate rays from the edges of the source’s alpha channel instead of its RGB channels. This will typically reduce the rays generated from internal edges. Values between 0 and 1 interpolate between using the RGB and the Alpha.

Rays Under Source:   Default: 0,  Range: 0 to 1.
Set to 1 to composite the Source input over the rays.

Source Opacity:   Default: 1,  Range: 0 to 1.
Scales the opacity of the Source input when combined with the rays. This does not affect the generation of the rays 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.

Matte Type:   Popup menu,  Default: Luma.
This setting is ignored unless the Matte input is provided.

Luma:  uses the luminance of the Matte input to scale the brightness of the rays.

Color:  uses the RGB channels of the Matte input to scale the colors of the rays.

Alpha:  uses the alpha channel of the Matte input to scale the brightness of the rays.

Blur Matte:   Default: 0,  Range: 0 or greater.
Blurs the Matte input by this amount before using. This can provide a smoother transition between the matted and unmatted areas. It has no effect unless the Matte input is provided.

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.

Opacity:   Popup menu,  Default: Normal.
Determines the method used for dealing with opacity/transparency.

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 Rays Length: Check-box, Default: off.
Turns on or off the screen user interface for adjusting the Opacity parameter.This parameter only appears on AE and Premiere, where on-screen widgets are supported.

 

  1. 3.       Sapphire GlowDist

Generates glows based on the distances from the edges of the source input. Any edges in the input image, where the brightness crosses the given threshold value, will generate an equally bright glow into the darker side of the edges. This is best observed when used on images with dark backgrounds.

In the Sapphire Lighting effects submenu.

Inputs:

Source:  The current layer.   The input clip that determines the glow locations and colors. This clip is also used as the background and the glows are layered back onto it.

Background:  Defaults to None.   The clip to combine the glows with. If no background is given, the Source is also used as the Background.

Matte:  Defaults to None.   If provided, the source glow colors are scaled by this input. A monochrome matte can be used to choose a subset of Source areas that will generate glows. A color matte can be used to selectively adjust the glow colors in different regions. The matte is applied to the source before the glows are generated so it will not clip the resulting glows.

        
 

 

Parameters:

Brightness:   Default: 0.8,  Range: 0 or greater.
Scales the brightness of the glows.

Color:   Default rgb: [1 1 1].
Scales the color of the glows.

Threshold:   Default: 0.5,  Range: 0 to 1.
Glows are generated at the edges of areas in the source clip that are brighter than this value. A value of 0.9 causes glows from only the brightest spots. A value of 0 causes glows for every non-black area.

Threshold Add Color:   Default rgb: [0 0 0].
This can be used to raise the threshold on a specific color and thereby reduce the glows generated on areas of the source clip containing that color.

Glow Width:   Default: 36,  Range: 0 or greater.
Scales the glow distance. This and all the width parameters can be adjusted using the Width Widget. Note that a zero glow width still enhances the bright areas; set the brightness parameter to zero if you want to pass the Source through unchanged.

Width Red:   Default: 1,  Range: 0 or greater.
Scales the red glow distance. If the red, green, and blue widths are equal, the glows will be a single color given by the Color parameter. If they are not equal, the glows will vary in color with distance.

Width Green:   Default: 1.2,  Range: 0 or greater.
Scales the green glow width.

Width Blue:   Default: 1.4,  Range: 0 or greater.
Scales the blue glow width.

Affect Alpha:   Default: 1,  Range: 0 or greater.
If this value is positive the output Alpha channel will include some opacity from the glows. The maximum of the red, green, and blue glow brightness is scaled by this value and combined with the background Alpha at each pixel.

Glow From Alpha:   Default: 0,  Range: 0 to 1.
Set to 1 to generate glows from the alpha channel of the source input instead of the RGB channels. In this case the glows 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.

Glow Under Source:   Default: 0,  Range: 0 to 1.
Set to 1 to composite the Source input over the glows.

Light Background:   Default: 0,  Range: 0 to 1.
Increase this to give a look of the glow casting light onto the background image. To see this more clearly you can also lower the Background Scale parameter or raise the Brightness parameter.

Source Opacity:   Default: 1,  Range: 0 to 1.
Scales the opacity of the Source input when combined with the glows. This does not affect the generation of the glows 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.

Opacity:   Popup menu,  Default: Normal.
Determines the method used for dealing with opacity/transparency.

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 Glow Width: Check-box, Default: off.
Turns on or off the screen user interface for adjusting the Opacity parameter.This parameter only appears on AE and Premiere, where on-screen widgets are supported.
