Collapse Transformations
What are collapse transformations and how are they used in compositing?
GLOSSARY
Collapse Transformations is a feature in Adobe After Effects and similar software that allows for a more seamless integration of vector graphics and certain transformations when compositing. Activating this option for a layer or pre-comp ensures that transformations applied to it are rendered at the highest possible quality, and effects are preserved accurately. It's particularly important for maintaining the crispness of vector graphics and the integrity of 3D layer interactions within complex compositions.
When incorporating a vector-based logo into a motion graphics piece, enabling collapse transformations ensures the logo remains sharp and clear regardless of how it's scaled or which effects are applied, ensuring that it scales perfectly and integrates seamlessly with other composited elements.
Technical definition
Using the collapse transformations feature effectively manages how After Effects handles the rendering order of transformations and effects, particularly for vector graphics and nested compositions. It ensures that transformations like scaling are performed before rasterization, maintaining the vector data's integrity for crisp, clean outputs. This feature is essential for avoiding pixelation in high-resolution projects and when working with 3D layers, as it maintains the correct rendering order and spatial relationships between elements.
