Apply Lens Distortion Effects with Barrel and Pincushion Warping

Lens distortion is a visual effect that simulates real camera lens imperfections using radial polynomial transformations. It creates barrel distortion (edges curve outward) or pincushion distortion (edges curve inward), mimicking various lens characteristics.

The algorithm uses a radial polynomial formula: r_distorted = r × (1 + k1×r² + k2×r⁴). Each pixel is remapped based on its distance from center, with quadratic (k1) and quartic (k2) coefficients controlling the distortion strength and shape. Bilinear interpolation ensures smooth results.

Lens distortion is more subtle and controlled than fisheye. While fisheye creates extreme wide-angle barrel distortion, lens distortion simulates realistic lens imperfections with adjustable coefficients for both barrel and pincushion effects.

Yes, completely secure. All distortion processing happens entirely in your browser using Canvas API pixel transformation. Your video never leaves your device and is never uploaded to any server.

Use it for correcting actual lens distortion, creating vintage camera looks, artistic warping effects, simulating different lens types, creative video transformations, or adding subtle cinematic character to footage.
