export to MPEG2-DVD audio problem

[Jon Barrie]

Hi Richard,
If you have the audio running the way you like it with filters running and it’s all good in the TL then I suggest you export the Audio out as a seperate uncompressed WAV file. Check it for the prob’s you were facing. If they aren’t there then use this WAV. Or put the wav back into the project and make another Seq. Nest (add a seq to another like it’s a clip) the video only from the edit and use the WAV as your MIX.
Check the sync.
Add a 2 sec black video at the top and tail (before 1st frame of edit and after last frame of edit) so the DVD is loading and buffering itself in the blank section/s.
Let us know how that works.
If there is a targeted problem export each audio track seperately by muting all other tracks at a time. Bring them back and then apply the necessary filter for the problem spot by cutting around that spot this way the filter will only work on the section that you cut around. Reexport.
Audio doesn’t take anywhere near as much time to export as Vision so I usually export the Video as m2v – no imbedded audio and then export the audio as either WAV for Encore or as mpa from PPr for Encore. I think the filters are creating issues with the algorithms for the mpa/ac3 encode.
PS: You can use the MPG file and just remove the audio part of it in the authoring timeline and replace that with your final mix WAV or mpa file.
Cheers,
Jon

Okay, that works for me. Thanks. Now, when I export the audio in 5.1, Encore wont import it as an asset. How do I do what you said with 5.1 audio?

[Jon Barrie]

If you are using 5.1 – you’ll need to export it from PPro using the Surcode Dolby Digital export setting. You get 3 exports for free, then you need to pay for the license. Not many clients I work with need 5.1, it sounds like its cool, but unless they are really going to show it on a full surround system, it’s wasted. Drama uses 5.1 (7.1 really) to make audiences feel surrounded by the scene. Most situations really don’t need surround sound.
Once you export the 5.1 in Dolby Digital Encore will import that file.

That’s what I used, the free trial and it has the static as I described. Any way to export 5.1 and get rid of the static?

[Jon Barrie]

Have you exported the audio into a clean version without the need for any Filters?
Then done the export via surcode? If so there is a problem you need to address with surcode about the codec corrupting the clean uncompressed audio you are using.
Like I mentioned earlier, I don’t need to use 5.1 very often. But few times I’ve had to use it I never had an issue with extra noises.
Surcode might be able to help you with the problem, it might be on there site and have a fix. Only problem is you’ll need to purchase the license to keep working on getting your solution.

No I didn’t export. You mean export each channel that has the static, reimport, the export to 5.1? That sounds like it might work. I’ll give it a try, but to be honest, why should have to? That’s alot of exporting and reimporting. Why can’t I just use the darn filters without doing that? I’ll chalk this one up to another reason to get FCPRO, and add it to the list of problems with this frustrating software.

On a side note, I’m glad that you are happy with stereo with your projects, but I am showing my project in theatres and it must be in 5.1. Just not an option, unfortunately.

Now, how can you only export one or two specific channels without including the others?

[Jon Barrie]

I’d say that the problem is a conflict of some sort with either your computers hardware and the use of the filters while using the surcode export.

Is the file you are working with a single 5.1 surround file or is it made up of other tracks that are being submixed into a 5.1 master output track?

FCP has a painful 5.1 export system I doubt you’ll find it easier. I’m certain this problem you are having is an anomaly.

I do my cleaning in Soundbooth or Audition. Do the Surround MIX in Audition. Export it as a 5.1 WAV. Import the Perfectly clean 5.1 WAV into Premiere Pro and export the single 6 channel mixed file with surcode and never had a problem.

I’d say there is a conflict in the surcode compressor being able to sample and resample with the filters on. Just get the audio setup so the filters aren’t needed for the export to surcode.

“Just get the audio setup so the filters aren’t needed for the export to surcode.”

Can you ellaborate on how to do this?

Thanks!

You also wrote this in another thread:

“Audition will do the 5.1 uncompressed WAV. Bring that into Encore and let encore convert the WAV into the ac3 there. I’ve had plenty of success with it and it sounds great.”

I have my audio exported in 5.1 WAV and it sounds great, but Encore won’t let me import it, saying something about it only being able to support 2 channels, or something like that. You are saying here that you can import 5.1 WAVs. How can I do that?

[Jon Barrie]

Ok. I’ll concede that I thought I was using 5.1 WAVs in Encore. Turns out I was thinking about the Stereo WAVs. 5.1 needs to be compressed for Encore. My apologies.

If you have the 5.1 WAV and it sounds clean – great. Technically I’m assuming that this file doesn’t require any more filters. If so then you have a clean WAV to use.

If you open the WAV in the source monitor you can then export the surcode from there.

Should all work then.

Let me know.
