Best Formats for Slides and Presentations

When you are sending us your slide decks or presentation, there are some important steps to follow to ensure that the streamGo platform can display your slides correctly and as intended.

Things we will cover:

  • PowerPoint - the software to use when making your presentation
  • Widescreen (16:9) - the layout and size that we will use when making your slides
  • .MP4 - the type of file we will use for any videos in your presentation
  • .PPTX - the file type for your presentation once finalised and sending to streamGo

Creating your presentation:

Before you do anything, you need to consider how you are going to make your presentation. We would recommend that you use PowerPoint, as this is what our system uses to display your slides and it ensures good compatibility.


In PowerPoint, create your presentation including and text, images, animations etc. If you use a custom font you have purchased or downloaded, you must let your Project Manager know in advance of your event and send us a copy of the font files. For the layout of your slides, you should use a widescreen 16:9 ratio. To access this, click on 'Design', 'Slide Size' and finally 'Widescreen (16:9)'.


When adding videos to your PowerPoint, make sure to review your presentation to check if the videos are playing back correctly. We recommend sending the presentation to a colleague and checking the can view the videos through the presentation, without needing the original file. Good points to check include seeing whether the video is playing smoothly and the sound is working correctly. Whenever you include videos in your presentation, we suggest that you set up your event as a playlist event. More information on this event type can be found here.

Note: We cannot play videos in your slides that link to other websites such as YouTube or Vimeo. These videos must either be embedded or played as part of a playlist.

Once your presentation is complete and finalised, you will need to save is as a .PPTX file. This is something plainly referred to as 'PowerPoint Presentation'. If you have chosen to use another type of software such as Keynote on a Mac to make your presentation, then in most cases you can still save this as a PowerPoint Presentation (.pptx) file. If you do use another software, we cannot ensure that all your design and content will display in the same way.
