thanks ill give that a go.

Help! I'm producing a video that has mainly imported clips at 16:9 and 2 clips at vertical video dimensions that must have been shot on a mobile. When I edit these clips the preview insets black strips down each side. All good. But I can't find a way to export the MP4 file that preserves these borders. If I stretch the aspect ratio, the black borders disappear and the vertical video gets distorted. Any help gratefully received about compiling a video with mixed aspect ratio clips.
