Convert WMA to MPG4

Encoding WMA audio to MPG4 video is what users commonly are attempting when converting Windows Media Audio Files directly to MPEG-4 Videos (.wma to .mpg4 conversion).

Use media editors and (online) converters, such as Freemake Video Converter, which lets you import WMA audio and export it in MPG4 format.

Also, you can refer to the WMA to MP4 conversion entry, since both file types are essentially identical. They merely differ in their suffixes.
