Blend Layer Width

Sets the width of the blend layer image. By default the image is drawn at its own size.

A value above 1 is pixels. On a still output that honors dpr, pixel values are multiplied by it, and an image layer drawn at its own size is scaled by it too; dpr does not apply to video output. A value of 1 or below is a fraction of the picture, less the pad on both sides. Setting only blend-w keeps the picture’s aspect ratio for the height, matching the Rendering API’s behavior.

Color layers always cover the picture, so blend-w applies to image layers only.

Aliases: blendw, bw.

Use blend-w[N] to target a specific blend layer, where N is 0–3. Layer 0 is either the bare blend-w or blend-w[0]; if both are supplied, the bare name wins.
