The operation of a Step. Inputs are indices of earlier steps.

Variants

Clip

The picture of the clip showing the composition.

Media

A host-supplied source at start plus the composition time.

Fields

source_id: SourceId

The source.

start: MediaTime

Source time at composition time zero.

Generator(Generator)

A picture the engine draws: a generator node, or a media node naming a generated source.

Effect

A registered one-input effect.

Fields

input: usize

The processed image.

effect: ClipEffect

The effect.

Transition

A registered transition at an explicit progress.

Fields

from: usize

The image at progress zero.

to: usize

The image at progress one.

effect: ClipEffect

The transition.

progress: Animated<f32>

Progress in 0..=1.

Transform

The input placed by a transform.

Fields

input: usize

The placed image.

transform: VisualProperties

The transform.

Merge

Layers composited over transparency, bottom first.

Fields

layers: Vec<StepLayer>

The layers.

Matte

The input kept where a second image says.

Fields

input: usize

The kept image.

matte: usize

The coverage image.

mode: MatteMode

Which property of the coverage image counts.

ShapeMask

The input kept inside shapes.

Fields

input: usize

The masked image.

masks: Vec<ShapeMask>

The shapes.
