The only software that uses .wve files is Filmora, or previously Wondershare Video Editor, and these are video projects saved with the software. So avi to wve conversion is more of import and edit of AVI videos using that software and saving the edits and changes as projects.
Otherwise, we do not have any information about what the use of such export might be, so if you struggle with .wve projects, it might be best to contact Filmora support or reach out to the online community for help.
