Some of the NASS authors (Podium Presenters, Best Paper Presenters and Innovative Tech Presenters) have been asked to also add a audio or video narrated presentation to their Stack in Learning Toolbox, as well as adding the Powerpoint presentation itself. Other authors can of course also choose to do the same.
If you are one of these authors then we recommend following the instructions from Microsoft (see links below) to add a narration to your powerpoint presentation and then save that as a video file to add to your Learning Toolbox stack. These instructions cover multiple different versions of Powerpoint.
Record a slideshow with narrations and timings (just follow the basic steps 1-5 in this guide) then: Turn your presentation into a video
Please note that Learning Toolbox does not support .PPSX files, so when you save your presentation as a video you should save it as an MP4 file, not as  a PPSX file.
Please also note that you should choose to save your video in 720p (or internet) resolution (not the 1040p default that Powerpoint offers) as this is the most suitable format for videos playing on the web.
Following these instructions will reduce the chance of hitting any upload issues due to the file size.
