Noise Type - select the noise type:
Scale - increase/ decrease the scale of the noise [x,y].
Offset - offset the noise position in x the y directions.
Minimum - set a minimum value for the noise (0 = black).
Maximum - set a maximum value for the noise (1 = white).
Time - this attribute is automatically connected to the comp's frame number. Disconnect it if you want static Noise.
Time Scale - increase/ decrease the speed of the noise.
Frequency - increase/ decrease the frequency of the noise. A higher value will give you
Amplitude - multiplies the Minimum and Maximum values.
Octaves - the number of octaves over which the noise function is calculated. Each octave is at about twice the frequency, i.e., half the size of the previous one, but you can alter this with the Lacunarity control.
Lacunarity - a higher value will create more or larger 'gaps'.
