Description
TweakColor has the ability to target specific hue and saturation ranges for hue and saturation adjustments. For example, you can target highly saturated reds (> 75% saturated) and reduce just them, leaving things like skin tones alone.
Based on the built in Tweak filter.
Requirements
- [x86]: AviSynth+ or AviSynth 2.6
- [x64]: AviSynth+
- Supported color formats: YUY2, YV12
Syntax and Parameters
- TweakColor (clip, float "hue", float "sat", float "bright", float "cont", bool "coring", int "startHue", int "endHue", int "maxSat", int "minSat", int "smooth")
- clip =
- Input clip.
- clip =
- float hue = 0.0
- Adjust the color hue of the image.
- hue>0.0 shifts the image towards red.
- hue<0.0 shifts the image towards green.
- Range -180.0 to +180.0, default=0.0
- Adjust the color hue of the image.
- float hue = 0.0
- float sat = 1.0
- Adjust the color saturation of the image by controlling gain of the color channels.
- sat>1.0 increases the saturation.
- sat<1.0 reduces the saturation.
- Use sat=0 to convert to GreyScale.
- Range 0.0 to 10.0, default=1.0
- Adjust the color saturation of the image by controlling gain of the color channels.
- float sat = 1.0
- float bright = 0.0
- Change the brightness of the image by applying a constant bias to the luma channel.
- bright>0.0 increases the brightness.
- bright<0.0 decreases the brightness.
- Range -255.0 to 255.0, default=0.0
- Change the brightness of the image by applying a constant bias to the luma channel.
- float bright = 0.0
- float cont = 1.0
- Change the contrast of the image by multiplying the luma values by a constant.
- cont>1.0 increase the contrast (the luma range will be stretched).
- cont<1.0 decrease the contrast (the luma range will be contracted).
- Range 0.0 to 10.0, default=1.0
- Change the contrast of the image by multiplying the luma values by a constant.
- float cont = 1.0
- bool coring = true
- When set to
true(the default), the luma (Y) and chroma are clipped to TV-range; - When set to
false, the luma and chroma are unconstrained.
- When set to
- bool coring = true
- int startHue = 0
- Starting hue to effect, in degrees. Exact magenta is ~ 50 degrees.
- Colors are 60 degrees apart. +/-30 around center covers full color.
- Colors run clockwise: magenta(50), red(110), yellow(170), green(230), cyan(290), blue(350)
- Range: 0 to 359, default=0
- int startHue = 0
- int endHue = 359
- Ending hue. If < startHue, we go clockwise.
- Range: 0 to 359, default=359
- int endHue = 359
- int maxSat = 115
- Max saturation level to effect. Sat is in percents running from 115%-0%.
- Default=115
- int maxSat = 115
- int minSat = 0
- Min saturation level to effect. Must be < maxSat.
- Default=0
- int minSat = 0
- int smooth = 16
- Interpolates past max/min sats to smooth out changes (avoid contours).
- Range: 0-64, default=16
- int smooth = 16
Examples
TweakColor with default settings:
AviSource("blah.avi") TweakColor(hue=0.0, sat=1.0, bright=0.0, cont=1.0, coring=true, startHue=0, endHue=359, maxSat=115, minSat=0, smooth=16)
