Preparation of your presentation

Note: Further information on the preparation and submission of all contributions in the Upload Centre was sent to all speakers and ePoster-authors by e-mail at the beginning of July. If you are an active speaker or ePoster-author and have not received any message, please contact us via


As a plenary, invited speaker or abstract talk

Please prepare your presentation as usual in PowerPoint in 16:9 format. State on your first slide your potential conflict(s) of interest(s), if there are any.

Choosing the programme for recording
A recording of the presentation is necessary to guarantee a smooth conference. You can find your exact speaking time in your personal engagement overview (sent via e-mail). 

It is up to you which programme you use for recording your presentation. However, we recommend using Microsoft PowerPoint from 2019 or Office 365 to record with a webcam. This works with Mac or Windows. You can find an instruction video here:

Older versions of Microsoft PowerPoint allow only the recording of sound. You can find instructions here:

Moreover, you can use the following services:

- OBS saves your recording(s) locally on your computer. It is an open-source recording tool. Since the tool can also be used for livestreams the handling is slightly complicated. However, if you need to record presentations frequently in the future, an installation of OBS could be useful.

- LOOM saves your recording(s) on servers in the cloud. With LOOM you can record presentations up to 5 minutes free of charge. There is also a one-time 14-day trial version to create unlimited videos (without automatic subscription) (for Windows and Mac).
Note: the activating page is a bit hidden. You can follow this link:

- Mac users can record their presentation with the QuickTime Player, but without a webcam.

Advice on recording:
• Test microphone and webcam settings before recording
• If possible, record with daylight or another suitable light source
• Avoid surrounding noise, remove disturbing sources (telephone, pets etc.)
• Record in small/not empty rooms (carpeting has a positive effect on the sound quality)
• Please enter you name in the footer of your presentation („Insert“ > „Header and Footer“)


As an ePoster-author

  • All ePoster-authors are requested to submit their poster in electronic form (ePoster)
  • Please prepare a one-page document (1 slide)
  • Allowed file types: PDF, JPG, PPTX
  • The choice of software for creating your ePoster is basically up to you (e.g. PowerPoint)
  • As the ePosters will be seen by the participants via their screens, we recommend to prepare your ePoster in landscape format. However, if you have already prepared your ePoster in portrait format, this is also acceptable.
  • Please ensure that the ePoster has sufficient quality, minimum resolution: 3840x2160, 72 dpi
