Is there a specific reason you have not updated to 8.0.1?
Also, what kind of camcorder did this video come from and how did you get it into your computer?
It has been updated to 8.0.1and converted mpeg files to avi file format and using the same files in pre elements 8.0.1
and even I have used windows sample videos (that comes with windows ) and it was doing the same thing with even those files.
so it does not matter for me from where I got these video clips .
Actually, it does.
What specs did you use to create your AVIs and what software did you use?
When you add these AVIs to your timeline, is there a red line above them? There should not be if you are using properly formatted AVIs and the appropriate project settings.
So we do need details if you want us to help you, bonhomie. Yours is not a typical problem, so we need to figure out what is unique about your computer, your settings or your video files that's causing it.
I have tried with windows wildlif.wmv file that comes with windows.
and got error with the same file as well.
I have downloaded one clip from website which is .mov and it was doing the same thing
i have tried with a new admin user account and tried to launch the software and used motion trakcer again did the same thing, error
Instead of WMV (tough to edit normally), or MOV, can you try with a DV-AVI Type II (note: all AVI's are NOT equal), and test?
