It's easy to draw a shape in Premiere Elements using the drawing tools in the Title Adjustments workspace -- but drawing a circle gets a little more complicated.
The easier solutions are:
1) Draw you circle in Photoshop Elements and save it as a backgroundless PSD file. It should import right into Premiere Elements.
2) Use the letter "O" in the Title Adjustments workspace. Certain fonts make it look just like a circle. Or you can use a Webding.
But if you'd prefer to actually draw a circle, I can tell you how to do that -- though it's a multi-step process that's more complicated than it ought to be.
What computer operating system is your Premiere Elements 13 running? Have you updated 13 to 13.1 yet using an opened project's Help Menu/Updates? If not, please do so.
Now to the circles and arrows for your video projects.....
a. Have you explored the opportunities for this in the project's Titler workspace Text Styles Animations Shape sections.
Please check out the following for circles....
b. Have you looked at the Expert workspace Graphics Tab offerings....you can use an arrow there (limited but some). You can create new circle or arrow graphics (png)
c. Do you have Photoshop Elements or Photoshop where you can create your circle on a transparent background, save the circle as a .psd or .png and import the .psd and .png into a Premiere Elements Project using Premiere Elements Add Media/Files and Folders. You can also create these graphics as png and place them on the hard drive so that you can access them directly from Graphics Tab within an opened project.
Please review and consider, and then we can decide what next.
