Bad Audio .MTS Files Premiere Pro CS4

Tags: #mts #adobe_premiere_pro_cs4 #avchd_audio #sony_nex_fs100

Hello, I've looked around and haven't been able to find anything related to this post. I'm importing an AVCHD 29.97 1920x1080 .mts clip shot on a Sony FS100 into an AVCHD 1080p 30 sequence in Premiere Pro 4.2.1. Everything looks fine except the red render bar appears and the audio is nothing but really bad static. If I render the work area it plays fine except for the audio (still static). If I play the clip in VLC it plays fine. Same with Final Cut Express  import via log and transfer (apple intermediate) - looks and sounds great. But I can't get anything but bad static in Premiere CS4 and After Effects CS4.

    There is a problem with certain audio formats from Sony AVCHD cameras.  I don't recall what (if any) the solution was.  Do some forum searching/browsing.

    If you have a red bar upon import but no work, that means your project does not match your file

     

    Are you 100% sure your video is 1080p and not 1080i ?

    >why would a 1080i sequence be the proper sequence for something shot progressive?

     

    I am on CS5 and you are on CS4... so my only GUESS is that CS4 is doing something different than CS5... or your camera is really shooting 1080i

     

    For more information on exactly what is inside your file...

     

    Read Bill Hunt on a file type as WRAPPER http://forums.adobe.com/thread/440037

    What CODEC is INSIDE that file? http://forums.adobe.com/thread/440037

    .

    Report back with the codec details of your file, use the programs below... a screen shot works well to SHOW people what you are doing

    .

    For PC http://www.headbands.com/gspot/ or http://mediainfo.sourceforge.net/en

    For Mac http://mediainspector.massanti.com/

    .

    If you have a red line over the timeline after importing a video and before adding any effects... your project is wrong for your video... read above about codecs

    .

    Once you know exactly what it is you are editing, report back with that information... and your project setting, and if there is a red line above the video in the timeline, which indicates a mismatch between video and project

    Audio Codec: LPCM

     

    Yep, that's the issue.  Sony cameras don't write the necessary header information to the file correctly, so PP has trouble with it.

     

    Like I said, search/browse the forums.  I just don't recall if there was a fix.

    CS6 should be out soon.  5.5 already blows FCP (7 and especially X) out of the water.  After 6 is released, Final Cut will at long last live up to it's name for many, many professionals, I think.
