AVVideoCompositionCoreAnimationTool

An object used to incorporate Core Animation into a video composition.

Declaration

class AVVideoCompositionCoreAnimationTool

Overview

Any animations will be interpreted on the video’s timeline, not real-time, so you should:

  1. Set animations’ beginTime property to AVCoreAnimationBeginTimeAtZero rather than 0 (which CoreAnimation replaces with CACurrentMediaTime());

  2. Set isRemovedOnCompletion to false on animations so they are not automatically removed;

  3. Avoid using layers that are associated with UIView objects.
