## F2QBlur

the script call is:-

## vcm.F2QBlur(clip [, int line = 1][,int x = 2][,int y = 2])

clip: input clip must have constant dimensions and of RGB or YUV or Grey format only. All 3 planes of RGB, and YUV formats are processed.
line: If set to 1 linear type (motion blur). If 0 circular type such as camera out of focus.
x: x coord of line end. Must be in range of 0 to 1/8 of frame width. For circular blur this is radius of circle. Minimum 1, max 1/8 of width. Value is symmetrical to origin i.e. -x to + x.;
y: y coord of line end. Valid values are from - 1/8 to 1/8 of frame height. Value is symmetrical to origin (-y to y). For circular blur Y value is ignored.

This transforms data into frequency domain utilising libfftw3f-3.dll ( or, FFTW3 dll, or fftw.dll) of fftw.org being available in path.
