Struct VideoLayer 

pub struct VideoLayer {
    pub source: PathBuf,
    pub x: i32,
    pub y: i32,
    pub scale: f32,
    pub opacity: f32,
    pub z_order: u32,
    pub time_offset: Duration,
    pub in_point: Option<Duration>,
    pub out_point: Option<Duration>,
}

A single video layer in a MultiTrackComposer composition.

Layers are composited in ascending z_order, with 0 rendered first (bottom of the stack).

Fields

source: PathBuf

Source media file path.

x: i32

X offset on the canvas in pixels (top-left origin).

y: i32

Y offset on the canvas in pixels.

scale: f32

Uniform scale factor applied to the source frame (1.0 = original size).

opacity: f32

Opacity (0.0 = fully transparent, 1.0 = fully opaque).

z_order: u32

Compositing order (0 = bottom layer; higher values render on top).

time_offset: Duration

Start offset on the output timeline (Duration::ZERO = at the beginning).

in_point: Option<Duration>

Optional trim start within the source file.

out_point: Option<Duration>

Optional trim end within the source file.
