No. Windows Movie Maker records in .wma (Windows Media Audio) format. However, you can import and edit .wav files in the program.
You cannot convert a Windows Movie Maker file into any other format. The only way to change the format is to Publish/Finish the project, which exports (mixes-down) audio/video properties into Standard viewing format. Once that is done, you can convert the file into whatever format you wish.
First you need to Publish/Finish the Audio project in Windows Movie Maker. The finished product when exported from the program is .wma. Then you will have to convert the .wma audio into .mp3 format using an audio converter.
If you are saying your audio/music can't be imported into Windows Movie Maker, then it is an incompatible format for the program. Audio formats compatible with Windows Movie Maker include:aif, .aifc, .aiff, .asf, .au, .mp2, .mp3, .mpa, .snd, .wav, and .wmaCheck the file name extension (format).
You can't change WMM (Windows Movie Maker) files into other formats. The way files are converted to other formats is through the Publishing/Finishing process.Publishing/Finishing the movie in Windows Movie Maker "mixes-down" audio and video properties resulting in conversion from WMM project format to a finished format.Depending on the Windows Movie Maker version you are using, you must either Publish or Finish/Save the movie project in order to change the file format.
You do not have any other audio publishing options other than .wma if you are editing it in Windows Movie Maker. My suggestion is... edit the audio in Windows Movie Maker; publish/finish it in .wma format; then convert it to .mp3 using an Audio Conversion program.
It means the file name extension (format) is incompatible with Windows Movie Maker, or you are attempting to import a DRM (Digital Rights Management) protected audio piece.
First you have to mute the video's audio in Windows Movie Maker. Once the audio portion of the Video is muted, you can import and drop the desired audio you want to use into the Audio/Music track.
You need an Audio Converter to do that.During the Publishing/Finishing process Windows Movie Maker automatically converts audio into .wma files. It does not allow you to choose any other audio format.Google: Free Audio Converters and download one online. Install the converter and follow the instructions for conversion. In your case, you want to make sure the Output Source Formatselected is .mp3.
