Prezi

You can insert the following video file formats to Prezi (online editor and PreziDesktop):

FLV, F4V, AVI, MOV, WMV, F4V, MPG, MPEG, MP4, M4V, 3GP

How it works: Prezi has a built-in, standalone video player for these video formats. After uploading a video, you can control the playback using a navigation bar when presenting manually. You can add videos directly to the path. In this case, videos will start automatically as you reach them in your presentation, and will stop as you move along on the path.

How to insert:

• Click Insert>File in the editor
• Choose a video file from your computer
• Insert the file into prezi, just as you would insert an image file. Once the video is uploaded to the canvas, you can click on it to get the zebra and then move, scale, or rotate as needed.

YouTube videos:

How it works: The Prezi editor includes a standalone navigation bar to control playback of YouTube videos. You can add YouTube videos directly to the path. In this case videos will start automatically as you reach them in your presentation, and will stop as you move along on the path.

How to insert:

• Click anywhere on the canvas to open a new textbox.
• Paste the URL of a YouTube video to the textbox (this is not the YouTube embed code).
• Hit OK on the text box. Once the video is selected in Write mode, you can use the Zebra tool to arrange it, or simply drag and move with your mouse.
