vertical video how to export without black on the sides
I've been given a video in a vertical format. If you were to look at the video on your screen, it would be about 6.5" wide and 7.5" tall. I've been asked to blur out a face. I import the clip, and FCPX fills up the 960x1080 with black bars to the sides. No matter what setting I use, there are always gigantic black bars on either side of the video. I can't find a setting for oddly shaped video or vertical video. How do I maintain the vertical video shape on import so that I can blur the face and then export at the same dimensions?
