BCC Lens Correction

Category: BCC Image Restoration

Effect Name: BCC Lens Correction

The BCC Lens Correction filter, part of the BCC Image Restoration category, was designed to reduce or remove image distortion in source image clips that were shot using a wide angle or fish-eye lens and to make simple perspective corrections. The filter includes presets that were specifically designed for go-pro cameras.

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.

Compare Mode

The Compare Mode is used to view the filtered result alongside the original source layer. Several split-screen and side-by-side display options are available.

For more information, see Compare Mode.

• Correction: Controls the magnitude of the lens warping correction. Smaller values will correct for moderate warping, whereas more exaggerated fish-eye / wide angle distortions will require higher values. Use negative values to correct for Pincushion distortions.
• Scale Master: Controls the amount of scaling/zoom applied to your clip after the distortion has been removed. Tweaking the scale control may allow you to recover more of the original shot but at the risk of reintroducing some lens warping at the outer edges.
• Scale X: Controls a separate scale factor in the horizontal direction. Useful in tweaking footage that appears squished or stretched after perspective correction.
• Scale Y: Controls a separate scale factor in the vertical direction. Useful in tweaking footage that appears squished or stretched after perspective correction.
• Rotation: Adjusts image rotation around the center point to allow fine tuning of the framing/perspective.
• Vertical Perspective: Make vertical perspective adjustments to restore straight lines to being exactly vertical.
• Horizontal Perspective: Make horizontal perspective adjustments to restore straight lines to being exactly horizontal.
• Pan: Adjust the framing of the final shot by translating the already corrected image horizontally and vertically.
• Lens Center: This parameter can generally be left at default settings but can be useful in fine tuning the lens distortion correction pass in situations where the lens center point (and hence the center point of the distortion) are slightly misaligned with the center of the image.
