Editing clip settings

Click the button above the video preview to edit clip playback settings.

Select the Use flip, rotate, and desqueeze settings check box in the Export pane if you're working with video that was filmed with an anamorphic lens and want to preserve the Flip horizontal and Flip vertical, Rotate preview, and Anamorphic desqueeze settings when transcoding. When the check box is not selected, letterboxing will be applied.
