I need to insert music from an ogg into a silent wmv video file. Is there any way of doing this without causing any quality loss? I've tried some applications that can be used to insert music into videos, but they're all all-purpose video editing programs with general editing options, and cause image quality loss when exporting the video, even if I select the original format. I don't need to edit the video in any way beyond inserting the music or change its format, so there's no need to re-process its frames' pictures like the tools I tried do. Does anyone know of any software or method to do what I need? Thank you.
