Feathering
What is feathering and how does it soften edges in motion graphics?
GLOSSARY
Feathering in motion graphics is commonly applied to masks, effects, or any graphic element that requires a soft transition at its edges. By gradually decreasing the opacity of the element's edges, feathering avoids harsh lines and helps integrate elements more naturally into the scene, crucial for creating depth and a polished look.
When creating a vignette effect around a video frame, feathering is used at the edges of the darkened area to ensure it blends smoothly into the center, enhancing focus without noticeable borders.
Technical definition
The process involves adjusting the feather radius — larger values create a wider, softer edge. This is done through software controls, allowing animators to dial in the desired degree of softness to seamlessly integrate elements within the scene, whether for aesthetic purposes or to highlight specific areas of the composition.
