I'm using UVS 11.5 Plus on Vista.

I know it's something stupid because it's always worked for me in the past. In fact, while fooling around with these clips tonight I got it to work once. But try as I might now, I can't get Duplicate Audio Channel to stop appearing as grayed out.

Anyone got any suggestions?

Thanks folks!

Ok, so you are in Audio view mode. Can we assume you have selected (i.e. clicked on) the clip in question so that it's highlighted. That when the Duplicate button becomes active...

Yes, the audio clip is selected.

However, I think I found the answer. Some of the clips are stereo -- with nothing in the right channel (hence the need to duplicate), while others (the ones I can't select this option for) are in 5.1 surround.

I can select the option for the stereo clips, just not the 5.1 clips.

I'm not sure how they got that way, although I suspect I did it with a default setting while trimming clips, etc.

I'm guessing that "Duplicate Audio Channel" is not possible for a 5.1 audio clip. It makes sense, although it might be a nice option to have in the future.

So, is there any way -- short of saving the sound as a file and using Audacity to convert it -- to change the audio properties to stereo from 5.1 using UVS?

I appreciate the response.

Hi Steve

You should be able to change the project properties to stereo from Digital Dolby 5.1 (Dolby Digital Audio, 48 KHz, 3/2(L,C,R,SL,SR)

Then render the clips using File Create Video File ¡VSame as Project Properties.

Or just select Customise and set the appropriate properties.

There is also the option to ¡¥batch convert¡¦ from the tools menu.
Here you can set your convert properties.

If the clips are part of a project, then at some stage the project will be rendered to a Mpeg 2, assuming you are creating a DVD.

Leave the audio conversion as it will be changed at this point. Just choose the correct audio properties for the render.

Is there a way to duplicate a mono track to both channels for the entire project rather than clip by clip? On projects with a lot of scenes, it's time-consuming to select each clip one at a time, and duplicate the audio. Also, I'm nervous I will have missed one. I tried highlighting the whole project, but then the Duplicate Audio option is greyed out. Thanks for your help!

I think there's a way to do this when it comes to creating the video file for some video formats; however, I am creating an AVCHD video format, and it doesn't let you do it with that format.

Hi pwholzel

Unfortunately there is no method to batch convert the clips from mono to stereo.
But there may be a work-round.

With the project editing complete,
Share--Create a Sound File (i would choose Wav then 'Options', select 48.000Hz 16 bit stereo from compression tab.)

The new sound file is a stereo copy of your projects sound.
Use this clip in one of the sound tracks.

Audio sync¡¦ should be ok

With your project on the timeline go to Share>Create Audio File. This will create one WAV file. You can then insert that WAV file onto an audio track for editing.

Trevor/Black Lab: curiously enough I was in a similar situation a few days ago. In fact, I had to remove one channel from the stereo audio of a VCD file which was 1 hour 40 minutes long. And of course, I wanted to duplicate the remaining channel... I tried your suggested work-around(s) and they did not work!

Yes, I could make a single .wav of the whole remaining channel of the project. And yes, I could insert it in one of the audio channels of VS and reactivate the original audio in the main video track. But all that achieved was to have two identical sound tracks *in the same audio channel* overlaying each other.

I finally managed the trick using a third party audio editing program (I used, in fact, a combination of the new Steinberg WaveLab 6 which came with X2 Ultimate, and Nero WaveEditor). In effect, I copied the existing single channel and inserted the copy in the other channel of the editing program, then re-rendered it. Then inserted *that* back into X2, and it worked just fine.

With your project on the timeline go to Share>Create Audio File. This will create one WAV file. You can then insert that WAV file onto an audio track for editing.

Seemed logical to me...

Good ideas, guys.

Ken, it sounds like you didn't render the wav file in stereo mode? And maybe you didn't mute/remove the original audio and replace it with the rendered wav file?

This should do the trick. Thanks!

Hi Ken

I understand what you are saying.

There seems to be a little confusion regarding Mono and Stereo

If the file was true Mono then creating the sound file would work as described, In fact changing the project properties to Stereo would probably achieve the same effect.

If we were to capture from VHS via Composite using video cable and only one audio cable, we would capture Stereo but one of the channels would be silent.
So what files are we working with Mono or Stereo???????????
I suspect we are talking Stereo with a silent channel.

A Stereo file with a silent channel is another proposition.

The change to stereo can be achieved with VS.
After completing the editing.
Change the project properties---audio to mono.
Render the project, the resultant video file having ¡¥true¡¦ mono can be used to Create a Sound File in Stereo

Add this sound file to the Project.
Remember to change the project settings back to Stereo.

A bit laborious but if you have a lot of clips the extra render may well be worth the effort.

Trevor -- that's it exactly! FWIW, the audio I started with was dual channel stereo. I had to remove the audio from one channel because, as I said, it was from a VCD, and I guess the only way they had of making it bilingual (Korean and Mandarin!!) was to put the Korean in one channel and Mandarin in the other -- the idea being simply, on playback, to mute whichever channel you didn't want to hear. I wanted the Korean, so deleted the Mandarin.

But as you say, that still left me with a stereo audio file, only one channel of which had anything on it. So I then had to copy that one active channel into the other to get dual channel stereo again!

I was close! Thanks for the clarification Trevor.
