I'm trying to import some videos of gameplay I've recorded into Windows Movie Maker 2010, all of which are AVI format files. However, when I import into the program, I get 7 second long clips without sound or video. In attempting to fix it, I get an error that says the following: "This file is corrupted or in a format that Movie Maker does not recognize," followed by a 0xC946001C error. In order to save or export the file, I have to remove these clips, which refuse to be fixed. In a bit of research, I downloaded several codec packs that include codecs for AVI files, but none of them have worked. The video files are fairly large too, (over half a gigabyte on average), so I don't know if there are any free trial video converters that would like to converter video formats of movies that size. Help please? I'm using Windows 7 32 bit Home Edition.
