Blurred

class Blurred(val radius: Float = 0.04f, val dim: Float = 0.0f) : Fill(source)

The clip's own frame, scaled to cover the output and blurred, behind everything.

The background is the frame scaled uniformly until it covers the output, centre-cropped, then blurred. A gap where no clip plays has no frame to blur, and fills with black instead.

Constructors

Blurred

constructor(radius: Float = 0.04f, dim: Float = 0.0f)

Properties

dim

val dim: Float

How far the background is darkened toward black, in 0f..1f. The background's encoded color channels are multiplied by 1 - dim, so 0f leaves it alone, 0.5f halves the stored value and 1f is black. The multiply lands on the encoded value rather than on linear light, so a backend whose color pipeline works in linear light compensates for its own transfer curve. Applies only to the background, never to the clip's own pixels.

radius

val radius: Float

The blur's standard deviation as a fraction of the output frame's shorter side, in 0f..1f, so the same edit blurs identically at any export resolution.
