I just finished a cue for a three minute clip, which was supplied as an Mpeg. I only have to supply an mp3, but for my own records I wanted to combine my wav file with the Mpeg and resave them as a single video file. So I put them together in Windows Video Maker. Unfortunately, when I resave it, the quality of the audio track is massively degraded. It doesn't seem to matter what format I save it in either. I tried all the 'high quality' options, some of which produced enormous files, but the audio still came out with added hiss, lost frequencies and a kind of scratchy quality.
I don't particularly want to shell out for Nuendo or Avid or anything in that league. Is there anything free or cheap which will combine my two files without trashing my wav file?
