aeFiller is a time saving node for removing unwanted elements, such as tracking markers, blemishes, or wires. Inpaint uses surrounding pixels to fill an area marked in the alpha channel of the source image or Matte input. The Stretch controls bias the inpainting in a defined direction and the Detail controls allow for greater control and cloning of high frequency textures from another part of the source image, or even from a different image using the Detail input. Inpaint also benefits from GPU acceleration to provide fast results.
