Hi,

I have imported video (with stereo audio) of my client (speaking at a podium, over a banquet hall house PA) system into Edit Video Enhanced with the following channels:

Left: Camera / ambient mic
Right: Speech giver's wireless lavalier / lapel mic

At times, I might wish to mix in the camera mic (audience applause, questions or other ambient sound), but mostly I wish to isolate the left channel with its clean audio of my client's speech.

When I reveal the audio track, I only see a mix of both left and right.

Is there a way to manage my audio tracks in true stereo fashion? Mostly, I want to isolate the right channel input but deliver it to both channels in my final production's audio mix-down.

Right now, my work-around is to export the audio to a different handler where I create a completely new audio mix-down which I then add back into my production as a music track while muting my video's native audio track.

Thank you in advance for your help.

Matt

1)  Extract the audio from the video using a left click on the video file using Media Manager.
2)  Load that file into "Edit Audio"   and move the little markers below the audio to one  get only one side (see images).
3)  Export that file to a new one and reload it.
4) Go to Sound Effects and select mono to stereo.  Save that file.  Sorry I could not get this part to work.  I looked at 4 other audio editors and none seem to be able to grab only one track and then make a stereo out of it.
5) Add the video to Edit Video -Advanced,   select to show the native track and then mute it.
6)  Add that last saved file to the music or other audio track.

I don't have a file like yours to try but the process should give you what you want. ofr part of it (have only one channel).

More on the above:  

After you silence one of the channels, you can select to export the file as a mono file by selecting "custom".   You should then be able to start a new project and add that mono file and then use the mono to stereo effect.

Hopefilly that covers your question.

See if this old thread will be of help too (steps 1-4), to supplement sknis suggestion above.
