There is an auto scene detector. But, just to be sure, what is it you're trying to auto scene detect and where is the video?
Just want to make sure we're talking about the same tool.
BTW, have you downloaded the free trial of Premiere Elements 15 and given it a test drive? That's the best way to find out if it will meet your needs.
I downloaded Premier Elements 15 and I have not found that functionality. I am wondering if I missed it or if it is not there.
Right-click on a video clip in the Project Assets panel and select Auto Analyze.
Thank you for your help.
