If you are talking about 'locking' tracks in Windows Movie Maker, there is no feature for doing that in the program. Other video editing software applications offer that feature, but not Windows Movie Maker.
I was able to view a video clip on a website a week ago and suddenly I can only get audio...no video. No change made in installation of Quicktime program on my Windows XP Home edition PC. No answer has appeared yet.
MP3- audio MP4- audio and video MP5- audio, video
Traditionally podcasts are only audio, however video podcasts (also known as vodcasts or sometimes vidcasts) are becoming more popular as well.
In AVS Video Editor, you can extract the audio.
To change the audio in the Audio/Music track, simply delete it and put something else in its place. To change the audio of a video in the video track, first Mute the audio of the video. Then place alternate audio in the Audio/Music track.
There is only one audio track to work with in Windows Movie Maker. The only other audio track is connected to the Video Track (the video's audio).Therefore, you can only have one video (with audio) in the Video Track and one audio/music insertion in the Music/Audio Track.
Video is Audio's partner.
Power Video to Audio Converter
No thats just for converting Audio not Video
You can't run the video's audio while video is paused. But, if you want to hear the video's audio without the distraction of the video, click the + button beside the Video track in the time-line view. Then, click, hold and drag the Audio track down into the Audio/Music track below.Close up the Video track. Then delete the video (or Remove it). The only thing remaining should be the original video's audio in the Audio/Music track. If you want the video back in the project, drag it back down into the Video track.
Audio-visual is a video having video as well as audio. Movies are example of some audio visual technology.
It can be video, audio but mainly its video and audio together. Found on Wikipedia
