Dissolve

Dissolve creates a weighted average of two inputs.

Inputs and Controls

Connection Type	Connection Name	Function
Input	0-9999	The image sequences to mix between.
mask	An optional image to use as a mask. By default, the dissolve effect is limited to the non-black areas of the mask. At first, the mask input appears as triangle on the right side of the node, but when you drag it, it turns into an arrow labeled mask. If you cannot see the mask input, ensure that the mask control is disabled or set to none.

0-9999

The image sequences to mix between.

mask

An optional image to use as a mask. By default, the dissolve effect is limited to the non-black areas of the mask.

At first, the mask input appears as triangle on the right side of the node, but when you drag it, it turns into an arrow labeled mask. If you cannot see the mask input, ensure that the mask control is disabled or set to none.

Control (UI)	Knob (Scripting)	Default Value	Function
Dissolve Tab
channels	channels	all	The dissolve effect is only applied to these channels. If you set this to something other than all or none, you can use the checkboxes on the right to select individual channels.
which	which	0	Select the inputs to dissolve between. Set this to an integer (whole number) to show that input, or a fractional value to dissolve between the two nearest inputs. For example, if you set this to 3, Nuke displays input 3. If you set this to 3.5, Nuke displays a mix between inputs 3 and 4.
mask	N/A	disabled	Enables the associated mask channel to the right. Disabling this checkbox is the same as setting the channel to none.
mask	maskChannelInput	none	The channel to use as a mask. By default, the dissolve is limited to the non-black areas of this channel.
inject	inject	disabled	Copies the mask input to the predefined mask.a channel. Injecting the mask allows you to use the same mask further downstream.
invert	invert_mask	disabled	Inverts the use of the mask channel so that the dissolve is limited to the non-white areas of the mask.
fringe	fringe	disabled	When enabled, only apply the effect to the edge of the mask. When disabled, the effect is applied to the entire mask.
