noise

Add noise on video input frame.

The filter accepts the following options:

all_seed

c0_seed

c1_seed

c2_seed

c3_seed

Set noise seed for specific pixel component or all pixel components in case of all_seed. Default value is 123457.

all_strength, alls

c0_strength, c0s

c1_strength, c1s

c2_strength, c2s

c3_strength, c3s

Set noise strength for specific pixel component or all pixel components in case all_strength. Default value is 0. Allowed range is [0, 100].

all_flags, allf

c0_flags, c0f

c1_flags, c1f

c2_flags, c2f

c3_flags, c3f

Set pixel component flags or set flags for all components if all_flags. Available values for component flags are:

‘a’

averaged temporal noise (smoother)

‘p’

mix random noise with a (semi)regular pattern

‘t’

temporal noise (noise pattern changes between frames)

‘u’

uniform noise (gaussian otherwise)

Examples

Add temporal and uniform noise to input video:

noise=alls=20:allf=t+u
