ffmpeg how to edit the saturation of a video

Written by John Riselvato - original link

Although the hue filter has a saturation variable, FFmpeg also has another filter called vibrance which is used to adjust the color intensity. Both filters give slightly different saturation effects but each has its place.

{width=“436” height=“240”}

In this example, all colors are boosted in the video, as seen in figure 59.0:

 $ ffmpeg -i input.mp4 -filter_complex "vibrance=intensity=2" -pix_fmt yuv420p output.mp4

{width=“436” height=“240”}

A specific color can also be set to apply a saturation. In this example, a negative intensity with a green saturation is applied. As seen in figure 59.1:

  $ ffmpeg -i input.mp4 -filter_complex "vibrance=intensity=-2:gbal=10" -pix_fmt yuv420p output.mp4

intensity
    Indicates the strength of the saturation boost. Positive value boosts while negative value alters (2 to -2 with default 0)

rbal
    Indicates the red balance (10 to -10 with default 1)

gbal
    Indicates the green balance (10 to -10 with default 1)


bbal
    Indicates the blue balance (10 to -10 with default 1)

rlum
    Indicates the red luma coefficient (1 to 0 default 0)

glum
    Indicates the green luma coefficient (1 to 0 default 0)

blum
    Indicates the blue luma coefficient (1 to 0 default 0)
