Crop the source before encoding

In the Export Settings dialog box, select the Source tab.

Select the Crop button and do any of the following:
•
To crop the image interactively, drag the sides or corner handles of the crop box around the source image.

From the Crop Setting menu, choose one of the following:
Scale To Fit
To eliminate letterboxing and pillarboxing resulting from cropping, or from using video of different pixel size.
Black Borders
Applies a black border to the video even if the target dimension is smaller than the source video.
Change Output Size
To automatically set the frame height and frame width of the output to the height and width of
the cropped frame. Choose this setting if you want to export content for use with Flash Player or other web applications
without black borders such as those used with letterboxing or pillarboxing.
Exporting video at the same dimensions or aspect ratio as the source video will prevent the black borders created when
scaling or cropping.
Note: The minimum size to which you can crop an image is 40 pixels by 40 pixels.
