    A low level exception occurred in ImporterFastMPEG(Importer)

    rant7

      I have recently purchased and installed Photoshop Elements 14 and Photoshop Premiere Elements 14.

      Having problem adding media files from hard disk to Photoshop Premier Elements 14 for editing.

      I had successfully edited one MPEG-2 TS Video file and exported as a .mp4 file.

      Now any subsequent video file does not open.

      I am getting "A low-level exception occurred in ImporterFastMPEG(Importer)" constantly.

      What does this error message mean? And what are the likely causes?

      When the mouse is moved over the video timeline strip near the bottom of the application window, the file name displayed is correct, but no pictures are visible.

      Getting this same error on the same original file that was edited successfully earlier.

      Have restarted Premiere Elements 14. No change.

      Rebooted PC and restart Premiere Elements 14. Still getting the same error when any video file is opened.

      Premiere Elements14 is up to date.

      Is a re-installation necessary?

      Running Windows 7 Pro 64-bit with 16GB memory.

          Uninstalling, running CCleaner and reinstalling may work. So might clearing the preference file (by hold down the Ctrl+Alt+Shift keys on the LEFT SIDE of your keyboard as the program launches). And, of course, make sure you have Quicktime 7 installed, per the program's requirements.

           

          What model of camcorder is your video coming from and what resolution is it?

            "A low-level exception occurred in ImporterFastMPEG(Importer)" possibly refers to either a CODEC or compression error. The generic error could be a bit more descriptive to be more helpful to assist the Premiere Elements user troubleshoot this error when opening files. I have uninstalled/re-installed the application, but the problem still remained. Premiere Elements is having difficulty opening up MPEG-2 files. A workaround to this problem is to use another application to convert the MPEG-2 file to a .mp4 file. Once the file is converted to an .mp4 file, edits can be performed using Premiere Elements.

                Very strange. What model of camcorder are these MPEG/MTS files coming from?

                  Steve,

                  The source of the MPEG-2 TS file is a Humax Personal Video Recorder.

                  Adobe Premiere Elements 14 will open some MPEG2 files from this device and some will get the exception error.

                  The strange part is Premiere Elements, having successfully opened a MPEG2 file from the Humax device, will get an exception error when the same file is attempted to be loaded at another time.

                  Using a video converter application to convert the Humax MPEG2 file to a .mp4 file before editing using Premiere Elements 14 is a workaround.

                    That's a DVR, isn't it?

                     

                    That's probably the issue. DVR video is not meant to be edited. It's meant to simply save video in as little space is possible -- which sometimes means compromising the video in ways that a camcorder would not.

                     

                    Have you tried converting the file to an MP4 with constant frame rate using Handbrake?

                     

                    Otherwise, we can dissect the video file with a program like Media Info and see what it's made of. But the end result will likely be the same: Some videos from this device simply wont' be editable while others may be.

                      Steve,

                      Don't know for sure about the DVR files not meant to be edited. The MPEG-2 files from the DVR could be played using the MS Windows Media Player, and that's a very fussy player. However; I have a workaround now by changing the MPEG-2 files that Adobe Premiere Elements won't open into .mp4 files by using either Any Video Converter or Format Factory (recommended by Adobe Help Desk). All's well.

                      Cheers.

                        Good news, rant! The converter is probably doing the same thing Handbrake would have done.
