G Diffuse is an improvement on the in-built FCP Diffuse filter that takes pixels in the image and spreads them randomly in a circle around the pixel position. Diffuse Radius controls the size of that circle, and governs the amount of that effect. G Diffuse improves on the in-built effect by allowing a number of iterations which improves the quality of the diffuse effect at the expense of render time, also allowing the iterations to be blurred before being added together to further soften the effect. To make the averaging work with the iterations, each application of the diffuse effect for a single frame must be random. If Random? is selected, the diffuse effect will also be random for each frame/field, not just within a frame.
1 to 20
The number of random diffusions that get added together to create the effect. Increasing Iterations increases both render time and the smoothness of the effect.
0 to 100
The size of the diffuse effect.
0 to 100
Size of the softening blur that gets added to the diffusions.
Sets wether the edges of the video get repeated by the diffuse effect or not. Turning this on keeps the video going right to the edge of the screen, instead of diffusing inwards.
Sets wether the frames use random diffusion or not - diffusion is always random for the iterations within a frame.
