Aescripts – Responsive Tools for After Effects is the newest tool for all types of responsive design, where objects and compositions are created to be responsive to any screen size or orientation.

Pixcode – Responsive Tools Features

• Adaptive text layers: The product has four Modes of auto-adapting text layers. These modes allow the text to fit in new contexts effortlessly.
• Anchor point locking: The locking of anchor points at nine different locations makes it neatly possible to determine the scaling and placement of elements.
• Layer locking: Fitting the layer to the composition frame in eight different positions allows it to respond dynamically and helpfully when the size or aspect ratio changes.
• Non-destructive workflow: The product allows completed desired effects to be executed without touching new layers or existing animations, keeping the workspace clean and efficient.
