I have two hour long of video, for some reasons, the audio cable was broken while recording and there is no audio in the right, but left track has good audio. I wonder how do i fix this problem, I am wanting the right to have the same soound track or the left one. Any idea of suggestion?
 
One way would be to save as elementary files with option set to save audio as LPCM/WAV. Then using Audition or Audacity or similar audio editor either copy / paste left track onto right track or create mono tracks depending on the program features.

How can you choose to save the audio as a wave file? I have been trying to figure that out and it keeps coming out as a AC3 file.......

Click the Options button in the file save dialog box and select LPCM for audio.

Pasting Audio

I have seen in this thread mention of pasting audio. I have a mpeg file with no sound on it, however I have an old VHS recording with the sound on and I would like to paste this sound onto the MPEG. I have found a programme, DVD Audio Ripper which looks as if it will allow me to extract the audio to a wav file but I can't work out how to paste it back into the mpeg. Can videoredo do this? Is DVD Audio ripper the best programme to extract the audio ( I have tried audacity as mentioned but that didn't seem to work.)

Any ideas gratefully received.

its the age of specialization

First, you have VRD save your original file into MPV/MPA formats.
The MPV will be the video with no audio, and the MPA will be audio with no video.

But, to answer the question, you can't paste the audio into VideoReDo.
The reference was to some audio-processing program, described above.

However, once you have a stereo sound track you want to merge with your video, you'd need to mux (multiplex or interleave) the sound track with your silent video track.
VideoReDo isn't really meant to handle that job either, but there are other programs which do.

IFOedit is a bitch to use, but it might do the job of re-muxing.
MuxMan is easy but very particular, and may or may not work, depending on the specs of your sound and video files.

Once the video and audio tracks are combined , then VideoReDo can edit and manipulate them.

I use two specific programs, both freeware for muxing & converting audio. ffmpegGUI which lets you convert AC3, MP2(A) or WAV to each other and ImagoMPEGmuxer to mux either AC3 or MP2(A) audio to MPV or M2V video.

I just wanted to follow up on this old thread because I was in the same situation. I am in the process of converting some old 8MM video into DVD. The 8MM tapes and camera I have are mono only so I ended up capturing all my audio to the "right" channel. Of course this is a less than optimal listening experience. I really didn't want to have to go through the demux/copy/remux solutions previously posted, it seems like too much work :). I ended up just using ffmpeg to "downconvert" the audio to 1 channel with this command:

ffmpeg -i tape1.mpg -vcodec copy -acodec mp2 -ab 192k -ac 1 tape1-mono.mpg

This saves all the steps and, if you have lots of tapes to do, can be scripted easily like this:

for /f %a in ('dir /b tape*.mpg') do ffmpeg -i %a -vcodec copy -acodec mp2 -ab 192k -ac 1 %~na-mono%~xa

Of course if VideoReDo could do it for me that would be best, but I'd rather have H.264 support first :)

Thanks!
