One important task of compositing is the removal of bluescreen or greenscreen. You can also drag the handle in the graph. You can also drag the handle in the graph.Įnter the value for delimiter D in the range graph. You can also drag the handle in the graph.Įnter the value for delimiter C in the range graph. You can also drag the handle in the graph.Įnter the value for delimiter B in the range graph. The A delimiter marks the value where you want the keying to start, the distance between B and C mark the length of the full effect and delimiter D indicates where the effect stops.Įnter the value for delimiter A in the range graph.

min keyer - use the minimum values of the red, green and blue channels to pull the key.ĭrag the A, B, C, and D delimiter handles in the graph to adjust your keying result.

max keyer - use the maximum values of the red, green and blue channels to pull the key.saturation key - use the saturation value to pull the key.luminance key - use the luminance value to pull the key.bluescreen - subtract the blue channel from other channels.greenscreen - subtract the green channel from other channels.redscreen - subtract the red channel from other channels.

blue keyer - use the blue channel to pull the key.

green keyer - use the green channel to pull the key.

red keyer - use the red channel to pull the key.

Select which keying tool you want to use for keying your sequence: Inverts the use of the alpha channel so that the result is a non-white matte.

union - create a combination of the matte and the existing channels.

intersect - create an intersection of the matte and the existing channels.

replace - replace the existing output channels with the matte.

Select how you want to combine the matte with the existing output channels. Render the resulting image into this output channel. Disabling this checkbox is the same as setting the channel to none.

Select the layer you want to use for keying.Įnables the associated output channel to the right.
