2021 Speaker Resources

This webpage has been created to help you, a presenter at the CIBSE Technical Symposium, to prepare and deliver your video presentation for the virtual symposium. The content of this page will develop as queries are raised but the information below will provide sufficient information so that you can confidently and simply produce a great video of your presentation. 

The 15 minute video below will provide the information and help that you need to produce the correct format video. 

If you are already confident in producing video of presentations the key information is that your video should be a 1280 x 720 MP4 video (known as 720p or HD) and it should last for (no longer than) 18 minutes for main presentations and 4 minutes for ‘compendiary’ poster presentations.

When your video is complete please submit it to the URL that you were given in your recent personal email. 

If you have any suggestions, tips, hints or queries please email them to
