BCC Corner Pin Studio

Category: BCC Match Move

Effect Name: BCC Corner Pin Studio

The BCC Corner Pin Studio filter, part of the BCC Match Move category, simplifies the work of creating corner pin inserts, with a single Mocha planar tracker to track the target surface and 4 offset pins to accurately position the source shot onto the target.

Working with the Filter

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.

Effect Controls

Mocha Mask and Track

Continuum effects include integrated masking and matte tools that allow you to restrict the effect to specific regions of the image.

• Mocha masks: used to create custom spline masks. Mocha also includes Matte Assist ML and Matte Refine ML, which use machine learning to generate and track masks.
• Pixel Chooser: used to generate geometric shapes, gradients, or mattes based on channel, luma, or color-based selections. Additionally, an AI depth map generator, and an AI-powered face detection model allow for precise control of masks and mattes.

For more information, see Mocha and Pixel Chooser.

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.

Workflow

Host Specific Workflows

Corner Pin Studio integrates with host specific workflows to generate dynamic results. In addition to basic standard controls, the plugin works with the host specific compositing requirements. Below you will find detailed tutorials illustrating individual host workflows that integrate motion tracking and masking to track text to a wall using corner pin studio.

• Adobe After Effects
• Adobe Premiere Pro
• Media Composer
• Vegas Pro 17
• Resolve

Common Workflow Settings

• Apply to Foreground is a unique workflow that allows you to apply the corner pin to the foreground image.
• Apply to Background is the most typical workflow for Corner Pin Studio. In this mode, your chosen source image will be pinned over the background. When selecting this mode, mocha motion tracker will use your background source for all motion tracking.

• Background/Foreground Layer: Contextual controls determined by the chosen workflow mode. These controls tell Corner Pin Studio what source image to use for the corner pin. After Effects users can use a host native dropdown to select the layer for the background or foreground layer. Media Composer users can simply select the filter layer or first below, while OFX users can select their source A or B layer.
• Show Background/Foreground: Will bring the background/foreground to the front, allowing you to view the background/foreground independently of any corner pin effect.
• Composite Over BG: Composites the foreground image over the background. Enabling this will alow adjustments to the Apply Mode in the Composite Group.

Corner Pins Group

The Corner Pins Group provides access to the four pins used to map the foreground image. You can manually adjust the position of the Top Left, Top Right, Bottom Left, and Bottom Right pins, or, more commonly, you can use the Mocha Motion Tracker to track the movement of the corner pin in the scene.

Transforms Group

The Transforms Group allows you to offset the position of the corner pin, adjusting it’s translation, scale, rotation and skew.

• Translate X/Y: Sets the position of the corner pin on the X or Y axis.
• Master Scale: Sets the scale along the XY axis.
• Scale X/Y: Sets scale individually along the X or Y axis.
• Rotation: Rotates the corner pin.
• Skew X/Y: Skews the perspective of the Corner Pin along the X or Y axis.

Source Pins/Crop Group

Source Pins adjust the locations in the foreground image that get mapped to the pinpoints. Typically they do not need to be adjusted, however, in certain circumstances where you want to set the pin to an area other than the corner of the image (for example if you are pinning a logo, or an arrow), you can manually adjust the location of they source pins. This is also good if you want to select a specific region of the image to crop.

• Crop to Source Pins: Enables crop for the corner pin layer, cropping the corner pin to the location of the source pins.
• Edge Choke: Adjusts the choke along the edge of the crop. higher values will increase the amount of choke.
• Edge Choke Softness: Adjusts the edge softness. Higher values will create more edge feathering, while lower values will create a sharper edge.
• Edge Choke Falloff: Adjusts the gradient of the feathering.

Render Group

Motion Blur allows you to enable motion blur for the scene. After Effects users have an additional option available which allows them to use the host’s built in motion blur controls. When motion blur is enabled in any host, the following controls become available:

• Blur Samples: Sets the number of motion blur itterations. Higher values will produce more samples, resulting in a smoother, more continuous blur.
• Shutter Angle: Adjusts the speed of the “camera” shutter. Smaller values will result in a shorter range of motion blur, while larger values will create a wider blur.
• Shutter Phase: Shifts the relative point in time in which the blur samples are created. Sample can be either generated from the previous or upcoming frame. By adjusting the Shutter Phase, you can change the look of the blur.
• Upsampling Method: Sets the quality of the render. There are a number of options to adjust the speed and smoothness of the corner pin warping.
  • Fast
  • Sharp
  • Standard
  • Smooth
  • Magic Smooth
  • Magic Sharp
• Downsampling Softness: Controls the softness for scale settings where the image is being down sized from higher resolution. provides anti-aliasing to the edges of the corner pin warp. Higher values will provide softer results.
• Inverse Warp: Inverts the corner pin distortion. Typically this is used in conjunction with the foreground workflow to allow you to unwarp a corner pin effect. An example would be if you used Corner Pin to add something to the background image.

Color Correction Group

The Color Correction group provides  a range of foreground color correction tools for aid in matching foreground and background colors to create a more convincing final composite.  A separate set of correction tools for just the foreground edge is found in the Edge Color Correction group.

• Color Correction On:Toggles all foreground color correction.
• Temperature: Sets the temperature of the foreground.
• Tint:  Sets the tint of the foreground.
• Saturation: Sets the saturation of the foreground.
• Brightness: Sets the brightness of the foreground.
• Contrast: Sets the contrast of the foreground.
• Gamma: Sets the gamma of the foreground.

Drop Shadow Group

• Shadow On: Enables an animateable drops shadow on the foreground image
• Shadow Distance: Sets the distance (in pixels) between the shadow and the image.
• Shadow Intensity: Sets the opacity of the drop shadow, scaled as a percentage. At a value of 100, the shadow is completely opaque. Lower Shadow Intensity values make the background visible through the shadow. At a value of 0, the shadow is completely invisible.
• Shadow Angle: Sets the direction of the drop shadow. A setting of 0° places the shadow to the right of the image; a setting of 90° places it directly below the image.
• Shadow Softness: Sets the softness of the edges of the shadows. A setting of 0 produces a sharply defined shadow with hard edges. Increasing Shadow Softness produces shadows with softer edges.
• Shadow Color: Sets the color of the shadow.

Light Wrap Group

The Light Wrap parameters reflects the background image around the edges of the corner pin image to form a border. This creates the illusion that light from the background is reflected onto the foreground. This creates a more convincing composite by making it appear as if the images were shot in the same environment.

• Light Wrap On: Toggle the Light Wrap pass.
• Lightness: Sets the lightness value of the reflected/wrapped image. Negative values make the reflection darker and positive values make the reflection lighter.
• Softness: Softens the edges of the border image that is reflected or wrapped.
• Width: Controls the width of the reflection or wrap that is generated. Higher numbers result in a larger border.
• Apply Mode: Determines the method that is used to composite the border. For descriptions of all the possible Apply Modes Click Here.
• Mix with Original: Blends the original and modified results. Use this parameter to control the effective amount of the light wrap adjustment.

Composite Group

The Composite Group contains options for compositing the foreground image over the background. This group is available when Composite Over BG is enabled.

• Opacity: Sets the opacity of the corner pin image. At an Opacity value of 100, the image is completely opaque. At a value of 0, the image is completely transparent.
• Apply Mode: Determines how the source and corner pin images are composited. This filter is most useful with Apply Modes other than Normal. For descriptions of all the Apply Modes, Click Here.
• Apply Mix: Blends the Apply Mode setting with the Normal apply mode. The resulting mixed mode is used to composite the Corner Pin media over the filtered layer. For example, if Apply Mode is set to Lighten, then an Apply Mix value of 0 uses the Normal apply mode; an Apply Mix value of 100 uses the Lighten apply mode. An Apply Mix value of 50 blends the two apply modes equally. You can use Apply Mix to soften the effect of a given apply mode, or to animate over time.
