Audio channel duplication

[erdna]

I have a number of short HD (.mts) files from an interview session. Unfortunately they have all "left channel only" audio. I can duplicate the channel to get dual channel mono audio. This takes quite some time to get them all separately processed. Is there a way to use the batch conversion option in VS to get the dual channel audio without converting to .mov?.

Hi Andre

I do not think you can do that as Batch will render the video.

Why don’t you set Duplicate channel, complete the project and render the project to a new video file.

Why bother converting individual clips?

By the way Copy and Paste attributes will paste the duplicate channel from first clip to all clips.

Hi Trevor,,
Thanks for your reply. The problem with those clips is that the audio is stereo with the right channel muted, see e.g.https://www.dropbox.com/s/0sznapd7iq7zw ... 3.MTS?dl=0
Rendering out without dupliication doesn't deliver two audio channels.
Putting all the clips together and rendering with the copied duplation attribute works, but I need separated dual channel clips, because they are needed in another NLE to be edited togheter with other (2 channel stereo) clips .
Splitting up again the combined/corrected clip is not an option because the splitted clips are only available for use within VSX.
I finally batch convert all clips (~40) tp .mov. This seems to work because .mov mixes both channels by default.
