I have a a sequence in Premiere built of After Effect compositions. In export, I have black bars on either side. The size of the sequence and compositions are equal (1920x1080). I tried to change my export settings to "stretch to fit," which worked the way I wanted to but did not apply to the first composition. The composition's settings are identical to the rest. In preview on the export page, it even shows that the entire sequence will be stretched the same in export. I am so frustrated, and this project is due at midnight. Please help!
