The conference itself will run on February 5-9, 2023 in parallel sessions with live introductions and Q&A. All parallel sessions will be streamed online and recorded. Online participants will have the opportunity to ask/answer questions through the online conference platform (e.g. MS Teams, details announced closer to the conference start date). 

Instructions for Recording: The easiest way to prepare your presentation video will be to subscribe to the free version of Zoom and use it to record your presentation video. A 10-minute presentation should be well below 100MB. See video instructions below,

·       Please check the recording for quality and understandability, and for time limits, as it needs to fit into the specified duration. 

·       Presenters record their face video side by side (this is possible with Zoom recording). This will help achieve higher audience engagement with the online presentations.

·       We recommend using a headset, so you won’t get laptop fan noise etc. in the recording.

·       Please play the recording after you make it to verify the audio quality.

·       Check the microphone setup.

·       We will preview the recording for quality and ask you to re-record if necessary.

How to install and setup Zoom and create recording

Detailed instructions on setting up a Zoom meeting to make recordings.

Alternative to Zoom recording,

You can use PPT Export Video or any other alternative software to create a recording of your presentation in MP4. 

Note if you use Voice-over-PowerPoint (available in PowerPoint 2016 & later) and create a PPTSX file, Export it to MP4. 

The MP4 generated by PPT is typically enormously large (vs Zoom et al) and will likely need to be compressed to meet the size limit of 100MB for author uploads. Please note a zip file will not be accepted, the video file must be in MP4 file format when uploading. Be sure to verify that the audio is included as there have been problems with PPT recordings. See the Microsoft support article,
