Hi, this is a great program. But sometimes I have a problem with the resulting .mov videos. In some areas of the image burned a strange stain appears sharply demarcated. It's weird because it only appears in some specific and not all. What can be the cause? I tried it on windows 7 and windows 8.1 with the same result. I use a 5D mark III with the latest magic lantern. A greeting and thanks for developing this great program!
