Presenters are free to choose how to record their presentation. The options described in the following (recording with Powerpoint, WebEx or Zoom) are suggestions only. Recorded presentations can be uploaded to ConfTool as .mp4 (preferred) or .avi files. The maximum file size is 200 MB.

Please make sure that your recording is of good quality (e.g. by using a headset or external microphone; please double-check the recording quality when using the integrated microphone of your laptop or desktop computer). 

PowerPoint 2010 or newer versions offer the feature to export a "narrated presentation" as a video. Please use the following link for instructions of how to record a slide show with narration (Microsoft`s official guide):

Follow the steps below to record your presentation:
