Struct Scene

pub struct Scene {
    pub fps: f64,
    pub canvas: Option<(u32, u32)>,
    pub lavfi_overlay: Option<String>,
    pub video_tracks: Vec<SceneVideoTrack>,
    pub audio_tracks: Vec<SceneAudioTrack>,
}

Expand description

A whole timeline’s worth of playback work, described without the editing model.

Fields§

§fps: f64

Presentation frame rate. Clamped to at least 1.0 by the runner.

§canvas: Option<(u32, u32)>

Explicit output canvas (width, height), or None to size from the base track.

§lavfi_overlay: Option<String>

Optional timeline-global lavfi filtergraph string (e.g. color=s=1920x1080:c=black@0.0,drawtext=text='Title') generated and composited as the topmost video layer, matching the export path. None = no overlay.

§video_tracks: Vec<SceneVideoTrack>

Video tracks, composited bottom-up: index 0 is the V1 base, 1.. are overlays.

§audio_tracks: Vec<SceneAudioTrack>

Dedicated audio-only tracks (A1, A2, …).
