VectorBlur2

VectorBlur: motion blur along motion vectors — every pixel is smeared along its u / v vector (uv channels) times motion amount (0.5), over the shutter set by motion offset (-0.5 centres it).

raw .md

VectorBlur: motion blur along motion vectors — every pixel is smeared along its u / v vector (uv channels) times motion amount (0.5), over the shutter set by motion offset (-0.5 centres it). Uniform or gaussian blur type; motion falloff (0.33) softens the ends. The vectors can be offset, inverted, un-premultiplied (uv alpha) or blurred first. Output uvs shows the prepared vectors. Use it after AIVectorGenerator, MotionBlur2D or a render with motion vectors.

Nuke equivalent

Imports from and exports to Nuke's VectorBlur2. The standard Nuke mask knobs (channels, mask, invert, (un)premult, mix) are mapped too.

Nuke knobs not in this list import as a knob of the same name, or are kept unchanged for export. See .nk import.

Defocus

Defocus: blurs the image with a lens disc (bokeh): defocus is the disc's radius in pixels, aspect ratio squeezes it.

ZDefocus

ZDefocus: depth of field from a depth channel — the image is cut into depth layers, each blurred by its distance from the focus plane and laid back over the others from the back to the front.
