Method and apparatus for creating digital video effects on a frame of original image data containing pixel values. First spatial frequency banded frames are created from the frame of original image data, such that each spatial frequency banded frame contains pixels having pixel values defining an image of a different spatial frequency band of the original image data. At least some of the spatial frequency banded frames for different frames are then selectively processed to different extents. In this selective processing, the pixel values of all pixels in each spatial frequency banded frame are adjusted to the same extent. The processed spatial frequency banded frames for different spatial frequency bands are then combined to result in a processed frame having an image that is modified with respect to the original image data.
