Review the Lecture Presenter Guidelines

Please reference the Lecture Presenter Guidelines as a resource as you prepare for your presentation at DDW 2015. Information regarding oral presenter expectations, preparing your slides, Speaker Ready Room hours, FAQs, tips, and more can be found in this central guide.

Prepare Your Slides

Supported Formats

DDW’s presentation management system is optimized for PowerPoint, whether created on a PC or Mac. To take advantage of advanced media support in PowerPoint, we recommend all PPT files be converted to the PPTX format. You can find the convert feature located under “File, Help” when you have your PowerPoint open. PDFs are also supported.

Mac users: Please note that Keynote files are not supported. Please export your presentation as a PowerPoint or PDF file for upload and be sure to review the result in the Speaker Ready Room where there will be technicians available to assist you.

Prezi files are not currently supported for upload.

Video and Audio File Support

Please see this article for file formats supported within PowerPoint.

Please consider compressing your videos. If you’ve authored your PowerPoint as a PPTX, there are tools within PowerPoint to do this automatically. Instructions are found here.

If you will be converting or authoring videos, we recommend H.264 encoding at less than a 5 Mbps bitrate for best performance. Typical resolutions in the meeting room will be 1024x768 for 4:3 presentations and 1280x720 for 16:9 presentations. A 1080p, maximum bit rate encoding will bloat the size of your presentation with no visual improvement and may actually hurt performance.

If you plan to play a DVD as part of your presentation, please notify a technician in the Speaker Ready Room so arrangements can be made for assistance in your meeting room.

Custom fonts

Only fonts included with Office 2010 are supported. For a list of these fonts, see this article. If you plan to use a specialized font, it must be embedded in your PowerPoint presentation. Some licensed fonts may not embed and should be replaced with a font included with Office. Click here for an explanation of this process.

Links to Web Pages

Meeting Room computers are not connected to the Internet. Links to Web pages will not function and may cause issues if clicked accidentally during your presentation. We strongly recommend removing all links from your presentation.

Backup Your Presentation

Please bring a copy of your presentation along with you when you depart for your meeting. Copy your PowerPoint and all movies to a folder on a USB or CD-ROM. While PowerPoint 2010 and later will embed movies by default, you should still bring the videos just in case. Prior versions of PowerPoint will not embed movies. It is a good practice to keep a second copy of your presentation and movies in your luggage.

Upload Your Presentation to the Presentation Management Site

Presentations can be submitted in advance of the meeting via the speaker presentation upload site or onsite in Washington, DC at the Speaker Ready Room. Presenters will receive an email with instructions on submitting their presentations when the upload site opens in March 2015.

Promote Your Presentation

Social Media Promotional Videos

DDW uses social media to promote the meeting and to encourage communication among meeting attendees, exhibitors and presenters. We invite you to participate by submitting a video about your upcoming presentation to be featured on the DDW YouTube channel.

You may use your video as an opportunity to introduce yourself and explain why attendees should attend your presentation. Please do not include any unpublished data in your video and limit your video to 2 minutes in length. To submit your video, simply email the file along with your presentation number to After review, it will be posted to a special playlist for 2015 videos. Visit the DDW YouTube channel to view examples of  2014 Presenter Promotional Videos.

Provide Your Twitter Handle

Provide your Twitter handle, if you have one, to help attendees of your presentation do a good job tweeting your talk. You can provide your Twitter handle up front, in your opening remarks or in your first slide. If you’re not on Twitter, it’s worth thinking about signing up, just so people can provide attribution for your work. To learn more about social media, plase visit the DDW website.
