The first picture shows how the video looks after rendering (Stretched out). The second picture shows how it appears on the movie maker preview with bars on the sides, as it should be. For some reason, the landscape oriented video clips are also appearing upside down in the rendered product, despite displaying correctly on the movie maker preview. I have never had this problem before, and I've made many videos like this. Do you have any suggestions on how to fix this? I have tried publishing it multiple times with the same poor results.
