How to upload presentation material ahead of the event

This article explains how a presenter can upload presentation material like their poster, slides, figures or video ahead of the event.

Updated this week

See this article on how to edit your submission. Below are some specifications about the different presentation material you can upload.

Poster

The poster needs to be:

  • Image format (jpeg, png, gif or PDF);

  • Maximum of 100 Mb;

  • The landscape format is ideal, but the portrait format will work as well.

  • There are no specific dimensions, but as a matter of comparison, something like 16 x 9 ratio would work.

Note: If you upload a PDF with multiple pages, the first page only will be converted into an image.

The poster will appear full screen in its tab. Buttons will be visible to zoom in and out. You'll be able to scroll through it using the mouse.

Slides (Powerpoint)

The Slides field accepts Microsoft Powerpoint file formats:

  • A Powerpoint format (.ppt, .pptx);

  • Maximum of 100 Mb;

  • Can have audio, but this will increase the file size.

How to compress a PowerPoint presentation

If the PowerPoint presentation's size is over 100 Mb, follow Microsoft's support article here to compress it.

If the file is less than 10Mb, a Powerpoint viewer will allow participants to view the Powerpoint directly on the presentation page.

Figures

You can add as many figures as needed using the upload section. The format accepted is:

  • Image format (jpeg, png, or gif);

  • Maximum of 100 Mb for each figure;

Click the Edit button to change the title and the description.

Video file

You can upload a video file as well. Make sure to respect those specifications:

  • .mp4 format;

  • Maximum of 1 Go;

How long is a 1 Go video?

It depends on the resolution:

  • 720p (HD) is ~5 Mb per minute: 3h20 minutes;

  • 480p (SD) is 2 Mb per minute: 8h20 minutes.
