box |
N/A |
The area of the input image you want to keep. Anything outside this box is cropped. You can adjust the following: • x - the distance (in pixels) between the left edge of the original image and the left side of the crop box. • y - the distance (in pixels) between the bottom edge of the original image and the bottom edge of the crop box. • r - the distance (in pixels) between the left edge of the original image and the right side of the crop box. • t - the distance (in pixels) between the bottom edge of the original image and the top edge of the crop box. • w - the width of the crop box. This is only available if you click the wh button. • h - the height of the crop box. This is only available if you click the wh button. You can also adjust the crop box in the Viewer by dragging its edges. |

black outside |

This renders as black pixels outside the image boundary, making it easier to layer the element over another. If you uncheck this control, the outside area is filled with the outermost pixels of the image sequence. In most cases, you should keep black outside checked. However, you may want to turn this off for camera shake, or if you want to texture-map or intersect the output with a similar shape. Note: Enabling black outside also adds a solid alpha covering the input image area if no alpha is present. |
