Waveform Height

The video-wave-h parameter sets the height of the waveform bounding box. The value is interpreted differently depending on its magnitude:

• Values ≤ 1.0 are treated as a fraction of the canvas height. For example, 0.2 occupies 20% of the canvas height.
• Values > 1.0 are treated as absolute pixels.

The default is 0.2 (20% of the canvas height).
