Preparing Electronic Slides, Still Images & Movies in Presentations

SIGGRAPH 2018 Slide Templates

Audience Photos and Videos Reference Slide

The audience is encouraged to take pictures or video when appropriate. Within your PowerPoint template, you will find two reference slides: one with a “Photography & Recording Encouraged” icon and one with a “Photography & Recording Prohibited” icon. In all presentations, the second slide must include one of the two icons.


Keeping your presentation within your program’s allotted amount of time is crucial when operating under a tight SIGGRAPH schedule. See below for some timing tips and tricks:

  • Find out how much time is allowed for your presentation, and then plan your talk and your number of slides accordingly to allow for a relaxed pace.
  • Think of what you would change if the presentation had to be shortened or lengthened.
  • Practice your talk before the conference. Time yourself. Then, at SIGGRAPH, come to the Speaker Preparation Room to upload your presentation and practice your timing.
  • Force yourself to slow down a little; a rushed presentation will create more stress for you and won’t be compelling.


The technical session rooms at SIGGRAPH 2018 are large, and your presentation must be legible from the back row. If you can stand two meters away from your computer’s monitor and easily read your slides, your text is large enough. To achieve this, limit each slide to eight lines of text or less and limit each line of text to 30 characters or fewer. Use a bold typeface, no smaller than 28 points, with generous line spacing.

Use keywords so that your slides will be quick and easy to read. You want the audience to hear your presentation, while the slides accentuate the points to remember. Use standard fonts. That way your presentation will be truly portable. Incorporate only the essential parts of a diagram and simplify whenever possible. While it is tempting to include detail for the sake of accuracy, too much will make the slide difficult to read and become a distraction. Break up complex diagrams into sections if you can, so that each section can be made larger and therefore more legible.


Avoid the use of ALL CAPITAL letters. Words written in ALL CAPS are harder to read and take up more space on the screen. Use bold face and italics for emphasis, or use a bright color such as yellow text when normal body text is white. Underlined text is not recommended.

Color and Contrast

Make good use of color and contrast. Dark backgrounds tend to be easier to view, especially with light text and graphics. Good background color choices are black, blue, maroon, or gradient dark colors. Good text colors are white or yellow. If you use a light background, use black or very dark text and graphics. Maintain consistency throughout your slides. Using the same background color, text size, text color, and uniform fonts throughout all the slides makes it easier for the audience to follow the flow of your ideas.

Using Movies in Presentations

Please review this information to be certain your movies will play on the SIGGRAPH 2018 computers. These tips were written for PowerPoint users, but the issues (files, folders, and CODECS) are common to most presentation software.

Files and Folders

Be sure to bring all the files associated with your presentation. (If you have movies that play in your presentation, you must copy each individual movie file onto your presentation disk.) Make sure your PowerPoint presentation and your movies are in the SAME folder. If you put videos in subfolders, they will likely not play (If you have already done this, we can fix it in the Speaker Preparation Room.)


If you used a special CODEC to create video compression, you must bring this CODEC program with you so we can install it on our presentation computer. If you are unsure about your CODEC, try your presentation on a computer other than one you use every day. Try one in another office or at a friend’s house. If you know the person who created the video, please contact that person and ask if the video includes any CODEC issues.

We Can Help

If you are unsure about which CODEC your movie requires, you can email a sample of one of your movies to the SIGGRAPH 2018 Speaker Prep Staff. We will test it and let you know if there are any issues. Send your questions or concerns to the Speaker Preparation staff.
