Prezi

Prezi doesn't currently have direct sound file support (e.g. for .mp3 and .wav files).

If you would like to include sound in your Prezi you should convert sound files to FLV or SWF format before inserting into your Prezi. Please read the step-by-step description on how to do this (and when to choose which file format) below.

1. FLV sound

How it works: Prezi has a standalone .flv video player that can also be used for adding sound files to your prezi.

• Add it to the path to automatically start when it appears in the path.
• Advance to the next path item to stop the video.
• You can also navigate in the sound/video file using the flv player's navigation bar.

How to implement: To use the player for sound, first add video content to your sound file - the same way you upload music tracks to YouTube.

• Import the sound file and an image as video content to a video editor software package. (We recommend iMovie for Mac, and Windows Movie Maker for Windows computers).
• Save the project in any video format the software offers.
• Convert this video file to FLV using a file format converter. We recommend the free online tool, called Zamzar.
• Once your video file has been converted to FLV format you can upload it to your Prezi by selecting Insert -> File from the Bubble menu.

Short summary: Prezi eats sound in FLV format. Sound files cannot be converted to FLV, since it is a video format. Solution: convert your sound file to a video file. Then you can easily convert your video file to FLV.

When to use FLV format: When you want to control precisely when the sound plays in your prezi.

2. SWF sound

How it works: Unlike FLV files, SWF files cannot be added to a standalone player inside Prezi. They appear as images do in your prezi. SWF files can be animations or still images, with or without sound. Once you upload them to Prezi, they will start to loop in continuous playback as long as the prezi is open.

How to implement:

• Upload an SWF sound file like an image (Insert/File in the bubble menu in Edit Mode. Always add an image to SWF sound or else your uploaded file will be invisible.
• Select and manipulate it with the Zebra tool just as you would with other media files.
• Note for developers: If you create swf files with code inside, you can have them start playing upon clicking. However, they cannot be inserted to the path and you can't have them start to play upon zooming with the path.

Short summary: You can upload sound to Prezi in SWF format. There is no player for this inside Prezi -- SWF files work like images you upload. If you add sound to an SWF it will loop continously. You must add an image to the SWF, otherwise it will be invisible in the Prezi editor.

When to choose SWF format: When you want your sound to play continuously as a loop throughout your whole prezi
