Audio Issues with Encore Blu Rays
Hi,
I’ve been have a recurring problem when authoring Blu-ray discs in Encore in regards to the audio, both 5.1 and stereo. My workflow is as follows:
-Export individual AIFFs of each channel from Final Cut
-Use compressor to encode AC3 files either using the Dolby 2.0 or Dolby 5.1 preset depending on the source files
-Import the AC3s into Encore and drag to the appropriate timelineThe audio quality is extremely poor, regardless of whether it’s played back on a 5.1 system or stereo system. It just sounds quiet and tiny. I’ve used the exact same AC3s in DVD Studio Pro and these DVDs have sounded phenomenal. I’ve tried retranscoding the AIFs to AC3 files and the issue has remained.
Any suggestions would be appreciated!
Thanks -

If Encore is not re-transcoding the files, then it has nothing to do with encore.
Is there any way you can play the ac3 files back in an application to test before bringing it into Encore?

As mentioned in my original post I’ve had no issues burning the AC3s in DVD Studio Pro or playing back in Quicktime/FCP/VLC.
Encore is set to ‘Don’t Encode’
Any other suggestions?

Are you using Adobe media encoder prior to importing to Encore? Because Media Encoder uses a very low bit rate for audio by default -for both PCM and Dolby, if memory serves me rightly its around 115Kbs – you need at least 224Kbs to get decent stereo, but you have to manually alter the bit rate in the Audio panel in the export Dialogue box – not sure if this helps.
