    Audio problems when exporing from Premiere Pro CS6

    SteveD333 Community Member

      I have a sequence in Premiere Pro CS6 which is I wish to export as a H.264 Blu-ray video file.  I have an issue with the audio.  Generally, I choose Dolby Digital as the Audio format and set the multiplexer settings to TS, leaving the bitrate and buffering details set to the default of zero.  The resultant video file (mt2 file extension) plays fine with Windows Media Player and that’s it.  No other software media player will play the file without omitting the sound.

       

      If I import the newly created video file back into Premiere Pro CS6 as a new project/new sequence, and play the file back in Premiere Pro, all I get is a high pitched humming sound instead of any proper audio.

       

      I compared against video files I’ve created with Premiere Pro CS5.5 and they playback correctly on everything I have.

       

      Using one of the CS5.5 created files, importing into Premiere Pro/Encore CS6, and exporting back out creates the same problem.  This is the first time I’ve used the CS6 version so I don’t know what’s happening. Any thoughts would be appreciated.

          set the multiplexer settings to TS

           

          Don't do that, leave it at None.

            Hi Jim, If I set the multiplexer to none, the audio format is PCM (which is fine) but I end up with a separate audio file.  That's not what I want.  I need the resultant file to include the sound, which is why in the past, I've multiplexed the audio.

             

            This is something I've done many times before, it's only since I moved to CS6 I've noticed this problem.

             

            Like I say, Windows media player plays back the video file fine, but even Adobe's own products can't handle it.

             

            The same problem appears whether I create a Blue-ray H.264 or Blu-ray MPEG file.

             

            If I compare two m2t files, file (a) created with CS5.5 and file (b) created with CS6.  Import them both into Premiere Pro and then check their file properties, they are identical, but file (b) just doesn't play the audio.  I get no sound from software media players, and Premiere Pro just produces a high pitched tone.  I have two CS6 installations on separate PCs, I get the same problem on both.  It's consistent in its results.

             

            Try it.  Load a video clip in to Premiere Pro (with audio) and export with these settings:

            Format: H.264 Blu-ray

            Preset: You can either choose a pre-defined preset or customise, I’ve tried all options.

            Multiplexer: set to TS – this forces the audio format to be Dolby digital.  All settings are defaults.

             

            Try and play back the resultant .m2t file.  Windows media player (Windows 7 x64) handles it fine, I get sound and picture.

            Import the file you just created back into Premiere Pro and play it.   High pitched hum where the audio should be.

              I end up with a separate audio file.  That's not what I want.

               

              For Blu-ray, it is.

               

              If not for Blu-ray, then use the H.264 presets, not the H.264 Blu-ray presets.

                Yes, same problem with me, worked fine in previous versions CS5 and CS5.5. For now i need to go back to those versions to work for Blu Ray Production again.

                  Definitely a bug in CS6.  We have dozens of Adobe Creative Suite installations at my place of work, both CS5.5 and 6.  All the CS5 versions work as expected.  All the CS6 versions have the same problem that even CS6 can't read it's own files.   If you export a H.264 blue-ray media file from CS6, then import it back as a new sequence, the audio is gone- or at least Premiere Pro can't interpret it.

                    This is not a standard or advisable work flow guys.  If you want a single file, use the H.264 output, not the H.264 Blu-ray presets.

                     

                    And if you want to use the export for further editing, you shouldn't be using either option, but a better lossless option like the UT codec in an AVI/MOV file.

                      The work flow is very different, depending on what material and what preferences are used. e.g. if we deliver to TV Stations for broadcast and online streaming TV we need to send them Blu Ray compatible TS Streams. For further editing the best way it to use HQ H264 encoding and uncompressed Audio, either Quicktime or MXF works fine.

                       

                      For now we need to export in intermedia file format and encode with Procoder, which works absolutely fine.

                        I am now experiencing the same issue.  However, I started with Adobe 6.0 and it this stuff was working.  I recently installed the 6.03 patch update - could that be the cause?

                         

                        Did anyone speak with Adobe support or report a defect?   

                         

                        So is the issue just playback within PP or is the encoding off somehow?  I too can play with WMP, but VLC has issues as does my Sony BD player in some cases.

                         

                        Layman's question: is the quality of using H.264/.mp4 for playback on a PC and PS3 the same, worse, or better than H.264 Blu-ray/.m2t?

                          I am having the same issue.  We need the TS for a custom STB playback.  When we encode is CS6 the audio is either choppy or non-existant.  But is fine if we encode in CS5.  Something has defintely changed.  This is a big issue for us.  We are looking for other encoding solutions now.

                            I just encountered a similar issue with a mp4 file when played back on a newer Sony BD player via a USB thumb drive.  Video looks great but no sound however when played on a PC with VLC or Windows Media Player everything works.  I have created other h.264 files with 5.5 that were used on this player and this is the first time we have had this problem.  Feeback from others that have looked at the issue is that they feel it is caused by a VBR AAC audio rather than using CBR as with bluray.  I checked some of the h.264 files created with 5.5 and in fact they were using CBR audio but that is not the case with 6 ( nor an option )?
