F2QMask function convolves the input clip with the given mask frame in spatial domain. The clip and mask(s) are transformed into 2d frequency using fft, multiplied and inverse transformed to get the convolved output. Mask can be a single frame, to be used for all the input clip frames or can be from a seperate mask clip, using successive frames as corresponding masks
Rescale facility is available.
Only YUY2 and YV12 formats are acceptable. Y values only are processed.Frame height and width must be multiples of 4.
