Struct ScenePlacement

}

One video clip placed on the timeline.

Fields are pre-resolved model projections (e.g. in_point defaulted, speed clamped, xfade_dur computed); media-dependent resolution (the effective clip duration when out_point is None) is done by the runner at open time.

Fields

source: PathBuf

Source media path.

offset: Duration

Global timeline position where this placement starts.

in_point: Duration

Source-file PTS at which playback starts (Clip::in_point, defaulted to zero).

out_point: Option<Duration>

Source-file PTS at which playback ends (None = play to EOF).

speed: f64

Playback speed multiplier (1.0 = normal), clamped to at least 0.01.

xfade_dur: Duration

Crossfade duration from the previous placement into this one. Meaningful on the V1 base track only; Duration::ZERO = hard cut.

xfade_kind: Option<XfadeTransition>

The xfade transition kind for this crossfade (V1 base track only). None when there is no transition; the runner defaults to Fade if a duration is set without a kind.

opacity: f32

Per-clip opacity in [0.0, 1.0].

layer: RealtimeLayerDescriptor

The dimension-free compositing description (effects, blend, position, and the opacity/position animation tracks). The runner realises it per frame via RealtimeLayer::with_dimensions.

fade_in: Duration

Audio fade-in duration (Duration::ZERO = none).

fade_out: Duration

Audio fade-out duration (Duration::ZERO = none).

volume: AnimatedValue<f64>

Resolved audio gain (dB), static or animated. A static value is applied once at open; an animated one is evaluated per tick.
