Sorry for the delayed message. Terrible Internet connection failures on my side, and my message got wiped out in the process.
The Elements Organizers each have known problems, either in import format or playback in its player. Although the properties
of your source media are important, I think we would get quick direction on this - Elements Organizer irregularities or actual problem
in the sources file by doing the following:
1. Open Premiere Elements to its Export workspace, and try to import this file from the hard drive to the project using Add Media/Files and Folders/Project Assets from
where you bring your file to the Timeline. Can you do that without any problems in video audio? If you can, then we are dealing with
an Elements Organizer issue that may or may not be resolvable.
Side note: when you import a file into Premiere Elements Editor project, a copy is automatically placed in the Elements Organizer that came with the product.
2. Then we might use the free codec utility named GSpot to try to get video and audio codec information.
We will be watching for your progress.
