I downloaded some interesting videos, and want to redub in them using video edit software and send them to my friends. I tried Windows Movie Maker. It can mute the audio of source video, and add new audio. But I really want to remove the audio from source video completely, rather than mute. Who can kindly recommend me some software?
Resolvent:
Strongly recommend Aimersoft Video Studio Express. Both Windows and Mac version are available. Just download the right version according to your computer system.
Click "Import" or "Media" tab to locate your target videos into the editing software, take the Windows version of Video Studio Express as the example. All the added video clips will be listed in the media library as the following picture shows.

Drag the videos from the media library into the timeline panel. Both the video and audio will be displayed separately in the video and audio line. Unlink the video and audio by right-clicking to choose "unlink". Then click "remove" to delete the original sound.
Note: if you would like to add some new sound, just add the sound recordings you wanted into the media library and then drag it to the timeline panel.

Preview the edited movie to make sure you have got what you want. Then save the edited video to iPhone, iPod, PSP, etc or computer. You can also upload to YouTube if you would like to share it online with more friends.

Note: If you would like to save the edited video to DVD, Aimersoft DVD Creator, which has both Windows and Mac versions, is a good choice to help you burn any video to DVD.
