Editing Premiere Elements

I have a VERY LONG list of tutorials in http://www.direct2usales.com/PrE2021.txt

It is a simple text file so you will need to copy-paste the links into your browser

You're asking, by the way, a pretty basic question about video editing. Combing little videos into big video IS video editing.

If you're intersted, I created a free Basic Training tutorial series that should get you started.

1.  Register the small videos with Add Media into  Project Assets 

2.  Select and slide the clips from Project Assets to the Timeline.

3.  Arrange and edit the clips to your satisfaction.

4.  Use Export and Share to select your desired format then Share to a location on your computer.

There are several good tutorials on YouTube that may make this easier.
