Here is a tutorial of how to organize all of your clips in the bar of premiere pro. In order to get a neat clip bar, you can use bins to store your clips. The bin icon is located in the lower left corner and looks like so:
Click on that and a new folder should appear among your clips.
Go on and title this folder, I had a lot of text slides in this particular video so that was the first one I created.
Next, just click and drag clips into that folder.
Then you can continue and make more folders for the other clips you have like the bloopers one I made below.
Once you have placed all the clips you needed into folders, you are good to go! Now your clips are neat, in folders, and easy to find.
Now, next time you start a new project and need some order, use this tutorial to keep some organization during your project!
