I have an old AviUtl project and the source files. But I lost the old index files. The project uses 4 .wmv files. Now, the audio is way, way off. It is playing audio from some unknown part of the file. Everywhere. The video is all OK. I think I created this project using Windows 7 and I am using 10 now. Just a wild guess - maybe the wmv importer is too different under 10?
Is there any way to recover this project? It has a lot of edits and transitions, etc.
