i have made a movie with audio (first time) quite chuffed with myself, however as I used an IPhone and daftly videoed in both landscape & portrait when I came to uploading to movie maker I had to rotate some of the clips, this has left a smaller view with a lot of background ...... can I change this to match the clips before and after that are in larger 'widescreen' thanks in advance for any help

regards
