Here is the scenario:  I am editing a project shot on film.  On day five the lab screwed up and didn't sink sound to picture so I had to import three tapes of sound from the sound mixer - but he rolled at 48K since the lab was syncing - my project type is 23.976 thus requiring 48048 to sync correctly.

The above is just information - NOT the question.

Question:  I want to bring that sound in again now stamped as 47952 with Michael Phillips' tool.  Is there any way to import the corrected sound files into Avid without having to completely recut the scenes? 

I just tried the files and Avid recognizes them and tells me I already have them in the project.  So can I somehow have Avid unlink and relink to new or do I have to rename them all, reimport, relink to video and rebuild the affected scenes?

THANKS!  Sure hoping there is a simple fix.

1) Try the "decompose" command on the seq, or delete the involved audio files from the media tool

2) batch import the sound files, You'll need to trick Avid driving it to the new files instead of the original ones; You MAY need to rename the new files as the old ones

3) relink to the video files

my best guess is that this will only work if the old and the new sound files are of the same duration; please let me know if this works

No  need to decompose (bad idea actually), no need to relink any files.

You would want to batch import the audio master clips you previously created (no specific need to deleted the current imports). You have synced those up to picture, and if you reimport them, you'll replace the data in the audio master clip, without breaking the link with the sync clips.

However, I doubt that batch import will work, since there is a difference in duration between the 48K and the 47K files (which even is the point of the exercise).

Can you try one clip? Just batch import the sound for one take, see what happens. If it does import correctly, double check for sync (it has changed since the speed of the file has changed). You might want to use the Perf Slip command to correct the sync on the already AutoSynced clips.

Job ter Burg:

Thanks man - you are right....when I try one clip Avid says this:

"The file "whatever.wav" contains a start time.  How do you want the start time imported?"

Then there is a drop down listing: 23.976, 24, 29.97 non drop...etc.

Then below the drop down: "The tape "whatever.wav:2007-1015" already exists in this project and is marked as "Non-Drop".  If this is correct select OK to continue the import.  If this is not correct, select Cancel and rename the tape in the deck control settings."

So...it actually looks like this will work if I choose the right setting.  The project is 23.976 but should the sound be imported as 29.97 non drop?  It seems like when you import new sound files Avid does them non drop but...29.97?

bump...

not sure if i should do 23.976 or 29.97 non drop...anyone done this before?

I believe the answer is that you need to know how the files were recorded, with 23 or 29.

okay, here's the answer for anyone else in this predicament:  what job ter burg suggested (batch capture) works beautifully...

job ter burg - i owe you big time.  THANKS.

2) batch import the sound files

So this is it, either getting rid of the offending files or not (via decompose or media tool as suggested) , now You're left with a bunch of audio corpses, but that won't hurt too much! I'm glad You did it.

audio corpses?  not sure what you mean... 

one note on this for anyone else reading:  even though the reimport worked, since frame sample rate is different, some of the in points on the slates were off and I had to adjust.  FYI.

the original audio files

You can't avoid that, but You've been lucky the files were the same lenght, You'll also notice that the clips will go out of sync while playing. This is what I feared when writing "please let me know if this works" in my first post. If I was You (and if I may) I would ask the lab to sync the very same tapes they delivered wrong and I'd redigitize the footage: three of them is too many and Your editing will be very unconfortable having to manually fix the sound every now and then (quite often actually). If You need any help as to how modify the clips to batch capture them again with the proper audio channels please feel free to ask.

via decompose

Again, decompose is a bad idea, since it might destroy all links between A, V and master clips and sequences. Decompose is not a method to delete media. Deleting the media is possible (from bin or media tool), but not even necessary if you batch import.

You'll also notice that the clips will go out of sync while playing.

I don't think so. The original, unmodified audio should run out of sync. The newly imported files should be in perfect sync. That was basically the purpose of the whole exercise to begin with.

Job ter Burg:

Decompose is not a method to delete media.

I suggested this as a way to make an offline copy of a clip without deleting the media, that can be safely deleted after fixing the troblemakers; never seen a case of destroyed links between A V and master clips but maybe I've just been lucky (I use Avid since 1990)

Job ter Burg:

this is the ABC of Avid, You know that I know that!

Job ter Burg:

I do agree with that, but as all this has been an unusual and iffy issue I can take into consideration any option and its opposite too (and in fact the clips imported and relinked fine but the slate was off sync) this is why in my post I used words like "try - may - my best guess - let me know if this works".

Jasper, are You back to normal?

Jasper/Job/everyone-across-the-board: have a nice week end
