I am making a slideshow of pictures and videos on windows 7 movie maker. I am using pictures and videos saved on my computer. My video is half an hour long.
All of the pictures I am using are very good quality, but when I open my movie maker project some of the pictures become very very pixalated and blurry. Every time I open my movie it's a different picture that's blurry.
Is there a way to fix this????

Please help me!!!
