Diagnose: subject is cut off or the video is unexpectedly cropped

Direct answer
Compare the original export with the destination's playback preview. The crop may be in your original, or it may be added by the player's frame. Editing a 9:16 crop cannot recreate detail that was already removed by an earlier crop.
