To add another slide in Prezi, open your presentation and click on the "Insert" button in the top menu. From the dropdown, select "New Frame" to add a new slide or frame to your presentation. You can then choose the type of frame you want, such as a blank slide or a template. After adding the slide, you can customize it with text, images, and other content as needed.
They are called animations.
Just create a new text box in Prezi and paste the URL into it.
If you are talking about adding text to animations using Windows Movie Maker, click on the "Titles and Credits" option in the Task pane. Follow the instructions.
Add more cool things like moving animations and crap. :)
You can't, not yet, but what you can do is to bend the text in an external program, e.g. SAI, then upload it onto Prezi.
To create a slideshow in your Prezi account, start by logging into your account and selecting "Create from template" or "Start from scratch." Once in the editor, you can add content, images, and transitions to your presentation. To present your Prezi as a slideshow, click the "Present" button in the upper right corner, which will allow you to navigate through your content in a slideshow format. You can also use the "Path" feature to define the order in which your slides appear during the presentation.
