Sapphire Plug-ins for Open Fx: FreeLens

S_FreeLens

Generates a distorted, defocused and light leaked version of the source clip to simulate the in-camera technique of holding a detached lens in front of the camera and moving it to create focus and light effects.

In the Sapphire Blur+Sharpen effects submenu.


Inputs:

Source: The clip to process.

Matte: Optional. If provided, the effect is only applied on regions of the source clip specified by the bright areas of this input. Pixels outside this matte are not affected, and do not contribute to the resulting affected pixels within it. This input can be affected using the Invert Matte, or Matte Use parameters.

Parameters:

Load Preset: Push-button .
Brings up the Preset Browser to browse all available presets for this effect.

Save Preset: Push-button .
Brings up the Preset Save dialog to save a preset for this effect.

Mocha Project: Default: 0, Range: 0 or greater.
Brings up the Mocha window for tracking footage and generating masks.

Blur Mocha: Default: 0, Range: 0 or greater.
Blurs the Mocha Mask by this amount before using. This can be used to soften the edges or quantization artifacts of the mask, and smooth out the time displacements.

Mocha Opacity: Default: 1, Range: 0 to 1.
Controls the strength of the Mocha mask. Lower values reduce the intensity of the effect.

Invert Mocha: Check-box,  Default: off.
If enabled, the black and white of the Mocha Mask are inverted before applying the effect.

Resize Mocha: Default: 1, Range: 0 to 2.
Scales the Mocha Mask. 1.0 is the original size.

Resize Rel X: Default: 1, Range: 0 to 2.
The relative horizontal size of the Mocha Mask.

Resize Rel Y: Default: 1, Range: 0 to 2.
The relative vertical size of the Mocha Mask.

Shift Mocha: X & Y,   Default: [0 0], Range: any.
Offsets the position of the Mocha Mask.

Bypass Mocha: Check-box,  Default: off.
Ignore the Mocha Mask and apply the effect to the entire source clip.

Show Mocha Only: Check-box,  Default: off.
Bypass the effect and show the Mocha Mask itself.

Combine Masks: Popup menu,  Default: Union .
Determines how to combine the Mocha Mask and Input Mask when both are supplied to the effect.
Union: Uses the area covered by both masks together.
Intersect: Uses the area that overlaps between the two masks.
Mocha Only: Ignore the Input Mask and only use the Mocha Mask.

Shift: X & Y,   Default: [0 0], Range: 2 or less.
Offsets the lens horizontally or vertically. Note that the image moves opposite to the lens motion. This parameter can be adjusted using the Tilt X Widget.

Tilt X: Default: 12.5, Range: -45 to 45.
Rotates the lens left or right about a vertical axis. This parameter can be adjusted using the Tilt X Widget.

Tilt Y: Default: 0, Range: -45 to 45.
Rotates the lens up or down about a horizontal axis. You can use Tilt X and Tilt Y together to rotate about an arbitrary diagonal axis. This parameter can be adjusted using the Tilt X Widget.

Distance: Default: 0, Range: -0.3 to 0.5.
Moves the lens away from or toward the camera. This parameter can be adjusted using the Distance Widget.

Rotate Highlights: Default: 0, Range: -180 to 180.
Rotates the lens about the line of sight. In a real lens this would rotate the iris, so the rotation is perceived as a rotation of any defocus highlights in the image.

Perspective Amount: Default: 1, Range: 0.25 to 4.
Controls the amount of lens telescoping while applying Tilt X and Tilt Y. Increase for more 3D perspective.

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

Defocus Width: Default: 0.104, Range: 0 or greater.
Scales the overall amount of defocus blur and highlights.

Focal Point Offset: X & Y,   Default: [0 0], Range: 2 or less.
Offsets the location of best focus in the image. This parameter can be adjusted using the Focal Point Offset Widget.

Focal Uses Mocha: Check-box,  Default: off.
Controls whether the focal point is controlled by the Focal Point Offset parameter or follows the Focal Point Offset tracked inside of Mocha.

Smooth Focal Track: Integer,  Default: 0, Range: 0 or greater.
Controls how many points to average when stabilizing the Mocha point track.

Chroma Distort: Default: 0, Range: any.
Adds some chromatic aberration around the edges of the image; red and blue wavelengths of light refract differently in real lenses, producing fringes of color where the rays strike the lens at oblique angles.

Rel Height: Default: 1, Range: 0.01 or greater.

Highlight Roundness: Default: 0, Range: any.
Modifies the shape of the simulated camera iris. A value of 1 produces a circle; 0 gives a flat-sided polygon with a number of sides given by the Shape parameter. Less than 0 causes the sides to squeeze inward giving a star shape, while a value greater than 1 causes the corners to squeeze inward, giving a flowery shape. Has no effect if the Shape is set to Circle.

Boost Highlights: Default: 1, Range: 0 or greater.
The amount to increase the luma of the highlights in the source clip. Increase this parameter to blow out the highlights without affecting the darks or mid-tones.

Vig Color: Default rgb: [0 0 0].
The color of the vignette.

Vig Blur Amount: Default: 0, Range: 0 or greater.
Blurs the borders of the image in addition to darkening them.

Vig Blur Inside: Check-box,  Default: off.
If checked, the center (undarkened) area of the image is blurred instead of the border.

Vig Source Brightness: Default: 1, Range: 0 or greater.
Scales the brightness of the source clip. To see only the vignette, set this to zero.

Vig Combine: Popup menu,  Default: Mult .
Determines how the vignette is combined with the Source.
Composite: composites the vignette over the source clip.
Mult: the vignette color is multiplied by the source clip. If the Color is not black, this will selectively colorize the vignette area.
Add: the vignette color is added to the source clip. This will have no effect if the vignette color is black.
Screen: the vignette color is combined with the source clip using a screen operation. This will have no effect if the vignette color is black.
Subtract Inv: the inverse of the vignette color is subtracted from the source clip. Inverse means white for black, yellow for blue, and so on. This mode looks similar to Mult, but a bit more severe; it crushes the blacks and leaves the highlights more. This will have no effect if the vignette color is white.
Vignette Only: shows the vignette pattern without the source clip. The output will be white where the amount of vignetting is greatest (e.g. where the source clip would be darkened completely).
Vignette Only Inv: shows the inverted vignette pattern without the source clip. The output will be white where there is no vignetting (e.g. where the source clip would not be darkened at all).

Luma: the luminance of the RGB channels is used.
Alpha: only the Alpha channel is used.

Blur Mask: Default: 0.05, Range: 0 or greater.
