    Premiere Elements 13 Audio in MTS file not present after 3:30 of a 20:42 video. How can I solve this problem?

    AaronGib

      Just to clarify:

      It does not show waveforms in the audio track after that time or have sound when playing back, but the audio "track" continues to the end of the video file. So the video plays fine for 20 minutes and 42 seconds, but the audio only plays fine for 3 minutes and 30 seconds of that total time.

       

      The file is an .MTS file. MediaInfo says:

      To complicate diagnosis: I installed the Camera Raw update last night before leaving for the day.

          On what computer operating system is your Premiere Elements 13 running? And, are you playing back this video in the Premiere Elements 13 Editor or the Elements Organizer 13 player?

           

          When did this problem first present itself....you mention installation of the Camera Raw update last night. Did the problem exist before and after the Camera Raw update installation?

           

          If you open a new project, are you getting the same result. Are there any irregularities in the video playback in the Premiere Elements 13 Editor? If so, are you seeing an orange line over your Timeline content when doing the playback in the Edit area monitor?

           

          Thanks for your video audio properties. Looking forward to your reply.

            Unfortunately ATR, I'm not entirely sure the problem did not exist before the update. Although I suspect I would have noticed it already, but as it happened, the audio terminates just after where I left off last night before installing the update.

             

            I'm running Win 7, 32-bit, SP1. Ultimately, I'm trying to edit the video file, once I finish annotating it and marking places, and I'm exclusively using the editor for these purposes.

             

            I tried opening a new project editing the same video, and the error was repeatable. There are no irregularities in video playback, only audio. I do see the orange lines over timeline content, and I have used the effects, keyframes, etc. to moderate volume, opacity, etc. before, but that is certainly not what's going on here.

             

            In fact, the waveform displays only to 3:30, after which time, the waveform is not pictured in the audio track, although the file clearly runs through to the end of the 20:42 total video length.

             

            I'm assuming it's some kind of codec error. The same video file plays properly in Windows Media Player or Corel VideoStudio X7. In fact, I "saved trimmed clip" in Corel and the problem has disappeared in Elements. I'm still interested in getting to the bottom of this, as I purchased Adobe Elements but not Corel, and have plenty more files that may have similar issues.

             

            If there is anything else I can provide information about in order to help you and others understand what is happening, please let me know.

              Just to clarify (and bump my thread): Once I saved the "trimmed" (I didn't actually trim it) file using Corel, it became a new file of the same type with the following MediaInfo, and is now allowing me to see the full length of the audio portion of the muxed .MTS file. Maybe the_wine_snob has a suggestion. I've read most of his posts about codec problems, but the GSpot tool isn't providing any especially helpful information, and I'm not sure how best to proceed.

                I did not get to your thread until now, and it is very late where I am. But, I did want to keep ypur thread as elevated as possible until the morning.

                 

                I would be interested in exploring

                (I didn't actually trim it) file using Corel, it became a new file of the same type with the following MediaInfo, and is now allowing me to see the full length of the audio portion of the muxed .MTS file.

                Apparently you posted the MediaInfo video audio information for the Corel export and say "..became a new file of the same type...". Do you have a MediaInfo video audio readout for the file before it went into Corel? Or, are you saying that before Corel and after are exactly the same. Obviously something has happened to the file going in and out of Corel, and I would seek clarification on what you have before and after Corel with regard to video and audio properties which include codecs.

                  No worries ATR. Thanks again for your interest in helping me with this problem.

                   

                  I have not experienced a recurrence of the issue with any subsequent files yet. I am working with the 3rd file in this series now. The problem occurred in the second file and was repeatable. The first, fourth, and fifth files in the five part series are small. Two is big and three is slightly bigger. I was working on file two when I experienced the error.

                   

                  To restate the error, in file two, the audio just drops out after minute 3:30 of the 20:42 total file length. The file is muxed. It is MTS format.  More detail about the file is in the first MediaInfo paste, before running it through Corel, in my first post. This problem only occurs when attempting to edit in Premiere Elements 13. The file plays fine (WMP, VLC), and may be editable in Corel VideoStudio Pro X7, although I did not bother to do any actual editing. What I did, was open the file in CVSPX7 and then use the command "save trimmed video". I don't really understand what that command does, but it took some time to render the video and output to a new file. The new file, let's call it, 002-1, generated the MediaInfo output in my 3rd post. It looks like some bitrate stuff changed and the file size changed slightly. But the previously missing audio reappeared in Premiere Elements 13 after the transcode to the new file in Corel.

                   

                  So what I'd like to avoid is having to do any transcoding. I want to make these chops from the original MTS file. I will accept making the chops to a gigantic uncompressed video file format as I have seen the_wine_snob recommend several times to avoid lossy transcoding. I would like a recommendation for what tools to use for this.

                   

                  The other video files are working for editing in Premier Elements 13 without this audio issue. They are from the same day and camera (I'm not sure what camera).

                   

                  Thanks again to everyone who has taken the time to read this thread, and especially ATR for his active participation.
