Creating a Crop Box
 
 
 

Use a crop box to view the colour changes to a limited region of the front clip. Colour changes only appear in the area within the crop box. This feature speeds up processing and lets you see the difference between the source clip and the result clip.

For example, while colour correcting, you can use the crop box to split the image window. The split window allows you to view the front clip and the result or matte clip at the same time.

To create a crop box:

  1. Do one of the following:

    Show small imageShow large image

    The crop box appears in the image window. The display inside and outside the crop box depends on how many clips are loaded.

    If you loaded: Inside the crop box: Outside the crop box:
    A front, back, and matte clip Shows the front clip in the opaque area of the matte and the back clip in the transparent area of the matte. Shows the back clip.
    A front and back clip Shows the front clip. Shows the back clip.
    A front clip only Shows the colour-corrected clip. Shows the non-colour corrected clip.
  2. To adjust the size of the crop box, drag on the corner points of the box, or modify the values in the Left, Right, Bottom, and Top fields in the Setup menu.
  3. To move the crop box in the image window, click a side of the box and drag to a new location. Alternatively, press Ctrl and redraw the crop box.
    TipIf Overlay user interface is enabled, the crop box will extend beneath the Overlay user interface. To access the bottom edge, be sure to grab from an area where there are no user interface elements.

To disable a crop box:

  1. From any Colour Corrector menu, disable the Crop button.

    When you disable the Crop button in a Colour Corrector menu, it is also disabled in the Setup menu.
