How to apply same editing to further audio tracks...

Hello all,

i've just made a very complicated sync between a video and audio track within an FCS project.

The video was untouched and i edited the stereo audio track.

Now i would like to apply the same editing to the .ac3 version of the just edited stereo version.

There is a way to do that without remake manually the full work on the ac3 version?

Many many Big Thanks in advance 🙂

You can't use .ac3 audio in Final Cut Pro.

Master the audio track you just edited and make a new .ac3 in Compressor. It will only take minutes to process.

Thanks Nick.

But this solution is not correct for me since in my editing i don't have the 5.1 channel that are instead present in the .ac3 version.

I think that it should be possible to convert the ac3 file in 6 mono aif channel and then i should edit those 6 channel with the same editing i've already made on the 2 channel version...

Then the question is:

Is it possible to "automatically" apply the same editing already made for a 2 channel track to a further 6 mono tracks ?

I know that there is something called EDL but i don't know if it could help in some way...

You might (and I emphasize might) be able to do this by making a duplicate of your sequence, selecting the audio clips in the timeline and making them independent and the reconnecting them to your new audio clips. Probably need to duplicate the audio tracks for each new audio element of the 5:1. Things could get screwed up, so make sure you have your project backed up. Might be simplest just to match your edits.

Thanks to all.

Finally i re-edited the six channel putting them below the already edited stereo in the same sequence.

Now it works well and the sync is quite perfect.

Now the BIG problem is how to send those 6 (FL FR C LFE SL SR) channels to compressor to make the DD 5.1.

Some help from anyone?

Thanks again..

Thanks for the link but i don't have Pro Tools... in that article there is the guide to make DD 5.1 with compressor (that is very easy to understand just opening the program) starting from the 6 mono channel produced by PT but nothing on how to export the required 6 mono channel from FCP...

If I remember correctly, just export each audio track individually. And then bring them into compressor.

Sorry, I thought that info was in the article as well.

Michael is right, you export them out of FCP individually.

This will work, althought there's probably a better way. Select all the clips but the one you want to export in the timeline and go to Modify: clip enable. This will turn off all the other tracks. Then do an export. Rinse and repeat as needed.

go into Sequence Settings - Audio Outputs.

there you select 5.1 monitoring & selec tmono for each track instead of stereo.

Back in the timeline you can control click on the track - ex. A1 & a popup menu will appear allowing to select which track you want. ie. A1 select A1, A2 select A2, etc.

Thanks a lot Jason!

To complete your solution i can add that after the 5.1 Audio output Sequence setting if you choose

to export audio to aiff(s) from FCP file menu and you choose channel grouped you will have your 6 mono channel exported with this single command.

Thanks again to all
