In powerpoint once you have recorded your voice over , select File Export and select either mp4 or mov from the file formats, both are video files.
You can then upload your video in MyStudies by selecting Create Item>Mashup>panopto>upload.
That’s it.
Who does this?
People with older Mac’s that can’t run the panopto desktop recorder application can use this route to pre record and upload a video to MyStudies.
