How To Separate Sound From Video?

You can use a video converter software(eg: Xilisoft Video Converter). Convert the video into WAV.. N play..

Adobe Premiere is a world know video editing software for both professional and home users. We can use Adobe Premiere to separate the sound track from video track. Every digital movie has separate tracks for sound and video. A video is a sequence of frames. A single frame is a picture or an image.

If we want to have both track separate then open the movie in the Adobe Premiere. The VCD (.that) file format is not supported by the Adobe Premiere. The movie must be in AVI, MPG or any other supported format. We can convert the file formats by using different video converter software.

Once we have opened the movie, we can seed the project window, a time line and a video window. On the time line we can see the at least two tracks, one for video and for the sound. We can right click of the sound track and then select the save option. The sound track will be saved separately.  Normally, this track is saved in Wave format. We can convert the wave file format to any other file format, if required. This can be done by using the sound converter software. The converter software can be found at download.com

The method of separating sound from video is that first of all by using VirtualDub we will separate from the video and save it in .WAV type. This .Wav file runs through cool Edit 96 and if we want any change, we can edit where required. This tape to which we are converting is recorded in hi-fi stereo, some time one side of the type become higher in level as compare to other side. We will then run .WAV file with the help of Diamond Cut Audio Restoration Tools. This tool is only use to smooth out any impulse noise in our source audio. After this, we will convert this .WAV file in to AC3 by using ffmpegGUI. This GUI has the same rate of bit that TMPGEnc take during the encoding of mp2 in frame serving job. The new AC3 file is same as mp2 in size. Then we will discard the mp2 in favor of AC3 for authoring to DVD.
We can do any sound enhancement with the help of DC-ART. We will start to handle 1st generation tapes. These tapes may be stereo or may be monaural audio.

This is not very hard thing to do.. The difficult thing is,, how can you edit the sound, like "splitting the voices and the musics". Sometimes, human voices are too low and the background music is too high,, so, how can you will edit? The answer for your ? Is this,, all the procedures are already mention in those previous comments... The only thing I want to say is,,, in every video editing soft wares, it is possible to split the voices and the video, that you may edit your video as you like... Thanks(may not be very completed answer)
