It has been a couple of years since I built a movie with the program. I think I am doing the same procedure to add mp4 videos to the movie, but the program rejects the file saying something is damaged. I am at a loss to know how to bring the video into the movie studio. Any help would be appreciated.

name of version is movie studio 14, I have changed the phone that I used to capture the mp4 videos ( samsung 42). I can play the video on the computer but when I try to add it to the studio task it is rejected. Help Help
