    A solution to the infamous "NEMFileWriter has detected upstream pipe stall" error

    Hello fellow editors,

     

    This past weekend I've been trying to make a timelapse from three huge AVCHD spanned files.

     

    I've been plagued numerous time by the "NEMFileWriter has detected upstream pipe stall" error. whether I was trying to transcode AMA, import or render the timewrap effect.

     

    First task was to convert these huge files to DNxHD 36. I couldn't do it with Avid, and couldn't do it with Sorenson Squeeze 8 neither (Anyway, it would have taken at least 5 times longer).

     

    So I searched the forums for solutions. None of these worked:

     

    - Playing a HD youtube video at the same time

    - Stitch the spanned files into one

    - Lower the priority of Media Composer in the task manager

    - Only allow Media Composer to run on one core through the task manager

    - Try the whole process on a SSD (It went way faster, but crashed all the same. My Samsong EVO is set for high performance in Samsung Magician).

     

    After countless unsucessful attemps, ultimately, the only thing that work for me is:

     

    Check the "Run in the background" box for transcodes (from AMA) and Timewrap renders. I then open the background queue to monitor, and left the priority as normal. And everything finally worked. (I didn't even have to stitch the spanned files together, AMA took care of everything).

     

    Hope this helps, even though I think this feature is only available from version 7 onward.

     

    Here are my system specs:

     

    Media Composer 8.3.1
