About the Geometry Pane

You use the Geometry pane to choose cropping and sizing settings, output media file sizes, and the aspect ratio (the ratio between image frame width and height).

Source Inset (Cropping) Settings

You can use the “Crop to” pop-up menu to apply a center crop or enter cropping settings in the fields described below.

  • Left, Right, Top, and Bottom: The four cropping fields (Left, Top, Right, and Bottom) allow you to crop the frame of your source media file in pixel increments. Most broadcast video files have overscan areas. If the output file will be shown exclusively on a computer screen rather than on a television screen, you can safely remove some edging from your file without affecting the picture area. The numbers give the distance (in pixels) between the edge of the original frame and the resulting cropped frame. All fields default to 0.

    Note: The regular (action safe) overscan area is the outer 5 percent of the image on all four sides. Cut in an additional 5 percent and you have the more conservative title safe area. So you can safely crop anywhere between 5 and 10 percent of your outer frame area and still preserve the essential material.

Dimensions (Encoded Pixels) Settings

The settings in the Dimensions section are only active when using the MPEG- 4, QuickTime Movie, and Image Sequence output encoding formats. For other formats, the settings are dimmed but show the settings that will be used when the batch is submitted.

  • Frame Size Width and Height fields: These text fields and associated pop-up menus allow you to customize the frame size and aspect ratio of your output media file. Enter a value in either the Width or the Height field or choose an option from the associated pop-up menu.

  • Pixel Aspect field: You can choose Custom from the Pixel Aspect pop-up menu and enter any value in this field. The pixel aspect ratio refers to the shape of the pixels in a digital image. This is especially important when using some filters. For example, if the graphic you use for the Watermark filter uses a circle and you want to be sure it still looks like a circle when finished (as opposed to an oval), you must choose the pixel aspect setting that matches your output format.
Output Image Inset (Padding) Settings

Use the following settings to apply and adjust padding.

Figure. Padding pop-up menu.
  • Left, Right, Top, and Bottom fields: Use these fields to add pixels of image “padding” around the sides of a frame. This is the opposite of cropping. In cases where the frame size of the output media file differs from that of the source media file, you may wish to pad an image rather than scale it.
