Please provide your slides in either Microsoft® PowerPoint (.ppt or .pptx file) format. Password protection and auto-advance functionality should always be disabled. For Pro webinars, builds and animations are supported. We also recommend that your first slide be a large image (or large text), as it will serve as the thumbnail of your webinar in your channel and on BrightTALK.
The size limit for your slides is 100MB and the best aspect ratio to use is 16:9. If you have more than one presenter on the live day, you'll need to merge the slides into one file to be able to upload into the BrightTALK Presenter Screen.
