More information is need to address your issue.
First what are the properties of this video that is giving you this error message?
I am looking specifically for video and audio compression, frame size, frame rate, interlaced or progressive, file extension for starters.
If you do not know, the name of the camera from which it came or better yet a MediaInfo (tree view) properties readout would be needed.
Assuming that your Premiere Elements 11 is on Windows. What is your computer operating system?
Let us start here and then move on from there.
From your post, I see no mention that you are trying to import one project file (project.prel) into another (project.prel). In your own words, you wrote
every time I try to open up a video file in Premeire Elements 11
So, I am proceeding in my questioning on the basis of what you wrote...you are dealing with the import of a video file of some sort. If my conclusion is incorrect, please let us know.
Thanks. Looking forward to your follow up.
Thank you for your prompt responses!
As it turns out, I had an outdated version of Quicktime on my computer, which somehow stopped functioning entirely. I didn't realize that Quicktime is necessary for using Premeire Elements. I downloaded the current Quicktime program and presto! Everything is working just fine now.
Great, great news. Great troubleshooting by you to identify the problem and correct it.
Thanks for the follow up which is important to all.
