You can't do that with audio on Windows Movie Maker. The application is very basic with limited features/functions. Masking is not a feature that is included.
No. There is only one audio track to work with in Windows Movie Maker. You can drag an audio backwards on the time-line to overlap the music... but it may not sound the way it would if it were on two different tracks. Perhaps you can try to use a streaming audio recorder to record audio on windows movie maker.
You can't do that on Windows Live Movie Maker, but you can extract the audio from a video in Windows Movie Maker v2.6 and save/publish it as an audio file.
No, you can't do that in Windows Movie Maker. You can overlap video by dragging the last import on the track, backwards over the first track though. However, this does not make for a great video. Then again, to each his own.
Use Windows Movie Maker
Speeds faster than 1x does not support audio in Windows Movie Maker.
Unfortunately, you can't do that with Windows Live Movie Maker (2011). It is a stripped-down version of Windows Movie Maker with very basic features, and only one audio track to work with. Sorry.
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.
No narration feature in Windows Live Movie Maker. Sorry.
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.
Microsoft Windows Movie Maker lets the user create video/audio projects.
Music / audio can be imported into Windows Movie Maker as long as the file is compatible. Drag and drop the audio file into the Music/Audio track in the Time-line view of the program. You will see the file appear in the Music/Audio track if the file is compatible.
Make sure you have Published/Finished your Windows Movie Maker project file first. Once you have done that, download and install an audio converter on your computer. Use the converter to convert the .wma audio file (produced by Windows Movie Maker) into a .mp3.
