    a low-level exception occurred in Importer FastMPEG

    Jeremy Gadd Level 1

      I am having serious problems with a wedding project. When I started it a few weeks ago it was all going ok when all of a sudden some of the files came up pixelated and blocky. I know the next question will be "can you post a clip here?". I will try to but it means showing the Bride and Groom's faces and as I have not yet shown them any of the video files I do not think it appropriate to do so here. In the meantime I am posting this here as I need some urgent help, as the project is getting very close to being overdue now.


      Technical stuff:


      • Files from Sony HXR-MC2000E - SD MPEG files;
      • Using Adobe Premiere CS6
      • Custom built Intel i3 3.30ghz pc
      • Windows 7 with Service pack installed


      When i opened the project today I got an error message: "a low-level exception occurred in Importer FastMPEG". Can anyone clue me up as to what this means please. To me, it seems like it could be related as I am importing MPEGs. I have tried re-importing the original files but they still come up as pixelated.


      Thanks again in advance for your help.

          As well as the answering the general questions here http://forums.adobe.com/message/4200840 please provide DETAILS of your computer hardware


          Especially the amount of RAM and number and distribution of hard drives and your brand/model graphics adapter and driver version


          For instance... my computer

          Asus P6 SE motherboard with Intel i7 930 CPU

          12Gig Ram and nVidia GTX 285 to use Cusa/MPE

          My 3 hard drives for video editing are configured as...

          1 - 320Gig Boot for Win7 64bit Pro and ALL program installs (2)

          2 - 320Gig data for Win7 paging swap file and video project files

          When I create a project on #2 drive, the various work files follow,

          so my boot drive is not used for the media cache folders and files

          3 - 1Terabyte data for all video files... input & output files (1)

          (1) for faster input/output with 4 drives

          - use drive 3 for all source files

          - use drive 4 for all output files

          (2) only 60Gig used, for Win7 & CS5 MC & MS Office & other smaller programs

          Search Microsoft to find out how to redirect your Windows paging swap file



          I can't help with your error (have never had that) but posting hardware details MAY help lead to a solution


          Also, if you are editing HiDef footage, your i3 is VERY underpowered... you need an i7 for "smooth" HD editing... plus, of course, enough hard drives to spread the workload (minimum 2 - or 3 like I have)

            Try this.


            Deactivate PP, close it.  Reboot and then restart PP.  Reactivate.
