Chroma Keying - Advanced Settings

[jannickgl]

Is there a way to set and read advanced upstream key settings like Key Adjustement, Chroma Correction or Color Adjustement of the Upstream Key when using Chroma ?

And if not, is it planned to add this functionality in the future ? 😄

Thanks in advance.

Hi @jackygeee,

Having a look at the Set methods documentation I find a few methods to make adjustments to keys and keyers (sorry... don't know the difference)

Have you tried with any of these ?

Keys

• setKeyChromaGain(mE, keyer, gain)
• setKeyChromaHue(mE, keyer, hue)
• setKeyChromaLift(mE, keyer, lift)
• setKeyChromaNarrow(mE, keyer, narrow)
• setKeyChromaYSuppress(mE, keyer, ySuppress)
• setKeyDVEBorderBevel(mE, keyer, borderBevel)
• setKeyDVEBorderBevelPosition(mE, keyer, borderBevelPosition)
• setKeyDVEBorderBevelSoftness(mE, keyer, borderBevelSoftness)
• setKeyDVEBorderEnabled(mE, keyer, borderEnabled)
• setKeyDVEBorderHue(mE, keyer, borderHue)
• setKeyDVEBorderInnerSoftness(mE, keyer, borderInnerSoftness)
• setKeyDVEBorderInnerWidth(mE, keyer, borderInnerWidth)
• setKeyDVEBorderLuma(mE, keyer, borderLuma)
• setKeyDVEBorderOpacity(mE, keyer, borderOpacity)
• setKeyDVEBorderOuterSoftness(mE, keyer, borderOuterSoftness)
• setKeyDVEBorderOuterWidth(mE, keyer, borderOuterWidth)
• setKeyDVEBorderSaturation(mE, keyer, borderSaturation)
• setKeyDVEBottom(mE, keyer, bottom)
• setKeyDVELeft(mE, keyer, left)
• setKeyDVELightSourceAltitude(mE, keyer, lightSourceAltitude)
• setKeyDVELightSourceDirection(mE, keyer, lightSourceDirection)
• setKeyDVEMasked(mE, keyer, masked)
• setKeyDVEPositionX(mE, keyer, positionX)
• setKeyDVEPositionY(mE, keyer, positionY)
• setKeyDVERate(mE, keyer, rate)
• setKeyDVERight(mE, keyer, right)
• setKeyDVERotation(mE, keyer, rotation)
• setKeyDVEShadow(mE, keyer, shadow)
• setKeyDVESizeX(mE, keyer, sizeX)
• setKeyDVESizeY(mE, keyer, sizeY)
• setKeyDVETop(mE, keyer, top)
• setKeyLumaClip(mE, keyer, clip)
• setKeyLumaGain(mE, keyer, gain)
• setKeyLumaInvertKey(mE, keyer, invertKey)
• setKeyLumaPreMultiplied(mE, keyer, preMultiplied)
• setKeyPatternInvertPattern(mE, keyer, invertPattern)
• setKeyPatternPattern(mE, keyer, pattern)
• setKeyPatternPositionX(mE, keyer, positionX)
• setKeyPatternPositionY(mE, keyer, positionY)
• setKeyPatternSize(mE, keyer, size)
• setKeyPatternSoftness(mE, keyer, softness)
• setKeyPatternSymmetry(mE, keyer, symmetry)

Keyers

• setKeyerBottom(mE, keyer, bottom)
• setKeyerFillSource(mE, keyer, fillSource)
• setKeyerFlyEnabled(mE, keyer, flyEnabled)
• setKeyerFlyKeyFrame(mE, keyer, keyFrame)
• setKeyerKeySource(mE, keyer, keySource)
• setKeyerLeft(mE, keyer, left)
• setKeyerMasked(mE, keyer, masked)
• setKeyerOnAirEnabled(mE, keyer, enabled)
• setKeyerRight(mE, keyer, right)
• setKeyerTop(mE, keyer, top)
• setKeyerType(mE, keyer, type_)

If you don't find what you need there, I'm afraid I won't be able to add it myself (would take too much time as it needs protocol reverse engineering), but the issue could be kept open in case somebody wants to have a go with it.
