Illustration stock animation is a type of digital media content that uses pre-made illustrations or graphics to create an animated sequence. These illustrations can be vector-based or raster-based, and they are often used to create explainer videos, advertisements, or social media content. The process of creating an illustration stock animation typically involves using software like Adobe After Effects, which allows animators to import and manipulate the pre-made illustrations in various ways. Animators can add movement, color, and effects to the illustrations to bring them to life and create an engaging animated sequence.
