Audio/Video Issues (Recording and Playback)

The most common VoiceThread issues involve issues recording or playing VoiceThreads. 

Settings for Your Computer

Make sure that the correct audio/video input/output is selected on your computer. The easiest way to test is to try using different programs. Are you able to play sound on your computer? Can you use the microphone/webcam in a different program (such as Skype for Business).

Adobe Flash

Having the latest version of Adobe Flash will ensure that VoiceThread is running smoothly. See Install and Enable Flash Player for more information.

Even if your computer’s audio settings are accurate, you might need to adjust your settings in Adobe Flash. Follow the steps below to verify and adjust them:

Right click anywhere on a VoiceThread slide.

Select “Settings…”

Click on the image of a microphone and/or webcam.

Select the correct input source.

Click “close”.

File Upload Issues

File Types

While VoiceThread does accept most file types for images, audio, video, documents, and presentations, you may want to confirm that your file is an acceptable file type. See File Types Accepted for more information.

File Size

Please note that VoiceThread does have a file size limit. No single file can be larger than 25MB. If you have a larger file you may need to break it up into smaller files or, in the case of video, compress the file.

Tips for uploading PowerPoint:

If your presentation uploads but the pages do not look quite right, please save your presentation in PDF format, and then upload that version to VoiceThread.
