    importing AVCHD file (*.m2ts)

    I work with MC 6 (trial version). Importing AVCHD file (*.m2ts) gives the following message:

    "Exception: NEMFileWriter: ExecuteInternal TIMEOUT - NEMFileWriter has detected upstream pipe stall..."

    How can I solve this problem?

    I also like to import this file using AMA. I use a SONY HDR-CX550VE camcorder.

    Now I can import using AMA.

    Re: importing AVCHD file (*.m2ts)

    Glad you got it sorted.

    Just for clarity, as this can cause a lot of confusion for folks, importing is the process of making Avid media from external source files. AMA is the link to of external source files with no Avid media being created.

    So calling AMA importing is unclear which process you are using.

    So for AMA you mount volumes (folders) or files and that effectively links to the external media.

    Hope that helps.

    Re: importing AVCHD file (*.m2ts)

    Just installed the MC 8.4 version for PC.  Using Dell T7500, 24GB RAM.

    Have always had not problems importing by AVCHD files until now.  Now I get the dreaded "...upstream pipe stall.

    Please tell me what I can do to have my AVID import the files normally into the bins.  I am willing to try anything.

    Thank you for any help you may have time to offer.

    Are you importing or (AMA) linking?

    Re: importing AVCHD file (*.m2ts)

    Maybe this can cure the AVCHD problem. In earlier vetrsions (6) of MC, also errors show when importing the mt2s files. Impossible to play the cips.

    I deleted the whole project and media. Restarted MC and tried to import again. File by file (not a whole bunch of files). Test each file if it plays well from the source window.

    Be  aware of using AvidFX filter. It might also show errors and completely impossible to use AvidFX.

    If nothing helps, then a re-install of MC can help to solve the problem.


    In my case, it did. Version 6.0.5


    BTW I don't use AMA.
