iPhone footage ends up with black border
Hi,
I'm editing iPhone footage to use on Instagram and I can't figure out how to NOT end up with a vertical black border on either side, once it's on Intsa. I've uploaded clips dircetly from the same phone and there have been no borders - the video filled the whole screen.
I imported the iPhone footage and dragged it to the sequence timeline and Premiere automatically created these settings for it:
And I used these output settings:

I also tried 'Scale to frame size' which usually fixes this problem for me but this time it made no difference.
I'm using an iPhone 14 and the latest version of Premiere Pro (as of this post).
My iPhone footage has the following properties:

Any help would be greatly appreciated!
Thanks in advance,
Mark
