Encore CS6 and multiple AC3 tracks

[Bill Stephan]

Jef,

Are you running Encore on PC or Mac? I ran into the same issue and found that Encore CS-5 and CS-6 on Mac has the option for “Do Not Transcode” in the drop-down next to the media, while Encore CS-5 on PC does not. I have not used Encore CS-6 on PC. All my 5.1 .ac3 files are DVD & Blu-ray spec-compliant.

I am on mac – OS10.6.8. I saw those selections in the DVD columns but not in the blu ray column.

Any other ideas?

Thanks,

Jef

Jeff,
you need to look at your project-preferences. if your project was created using “PCM-Audio”-preset, then all your audio will be trascoded to PCM, as it was selected project-wide.

you can´t change that afterwards – or in other words, you need to create your project from scratch.

encore only allow PCM or dolby digital audio

cheers

Thanks for the info. I had set the project up with Dolby Digital as I knew that the files were being created as AC-3.

These AC3 files were created with Compressor. They work just fine in a SD DVD project created in DVD Studio Pro with the same basic structure. So I have a fairly high confidence level that they are correct.

Any more ideas?

oh – my good,
jef – I remember some other guys mentioned the same problem, that 5.1 within encore will result into stereo-sound – seem to be a (one more) bug within encore.

please let me do some more investigations on that. I could have a deeper look into the projects and the resulting BDMV.

normally I create BDs using the pro-tools (scenarist, DoStudio or others).

keep you posted….

cheers

short update:
I created a short test-project with encore with 2 audio-trackt:

1. dolby digital 192khz 2.0 stereo
2. dolby digital 256khz 5.1 surround

afterwards I took the multiplexed BDMV-folder and demuxed it using EasyBD, which also created a project-file straight away. within this EasyBD-project I could see, that both streams will be shown correct.

1. DD2.0
2. DD5.1

also tested with a software-player – which showed DD2.0 and 5.1 within the on-screen-info.

as I haven´t got a 5.1-surround-sound-playback at the moment – I could only analyse what I could see so far – this is looking OK.

cheers

Thank you for testing.

Could you possibly make a screen grab of your asset page for me?

I am trying to compare how assets are brought into Encore as I feel this may be a part of the issue.

Cheers,
Jef

Hey Jef,
here you´ll see the screen-grab:

Great info. Thanks so much.

Here is my problem. I can NOT get my AC3 files to be “Don’t Transcode” and your screen shot clearly shows that you have been able to do this.

So — How did you do that!!! 😉

Jeff,
if you created your AC-3-files using compressor they should be valid for BD as well, or your global project-transcoding-setting is set to PCM audio.

could you please upload a small sample of your AC-3-files (2.0 + 5.1) so we could have a look at it.

cheers
