Creating and uploading your video presentation

Step-by-step guide to a successful video presentation

Create your video

The most successful presentation videos are well narrated, graphically rich presentations of your research that both highlight the main points and fill in the most interesting details. The least effective presentation video is a simple reading of your slides or manuscript. 

Suggested presentation video duration is:

  • 15–20 minutes for contributed
  • 20–25 minutes for invited presentations
  • 25–30 minutes for keynote presentations

Your slides will need to have audio narration embedded, and then you will need to export the presentation as an MPEG-4 (.mp4) file. SPIE can only accept the .mp4 format — other formats will not be supported. Presentation video files should be no larger than 2GB.

Your presentation video should include:

  • All slides of your presentation, formatted for easy understanding of the information on each slide
  • Clear narration with a pause for transitions between slides. PowerPoint, for example, does not record audio during slide transitions
  • Explanations for each graph, picture, and table
  • Widescreen format, using the 16:9 aspect ratio, to utilize the full screen — the standard 4:3 format will work but it will not fill the entire screen when in presentation mode

To record your audio:

  • Use any kind of microphone, including those built into laptops or tablets, so long as the resulting audio is clear and easily understood
  • Follow these step-by-step instructions on recording your audio in PowerPoint and exporting a PowerPoint file to .mp4
  • If you're using a web-based presentation program, such as Prezi, Slideshare, or Google Slides, you will need to use screen capture software to record your screen and presentation narration
  • Be sure to export your video, including all audio, as an .mp4 movie file for submission

Review your video

  • Is your file saved as an .mp4 movie file?
  • Is your file size less than 2 GB?
  • Is the audio consistent and clear, free from static, hums, hisses, or interference?
  • Is the audio at the right level, without having to adjust your volume very high or very low?
  • Does your talk start promptly? (Your narration should begin within the first 3 seconds)
  • Does your recording end promptly after your closing remarks, without being cut off early or continuing for too long?
  • Is there audio on every slide? Having audio on every slide ensures that each slide gets the correct timing before advancing. If a slide is self-explanatory, you can simply say, "This slide is self-explanatory."
  • Do all your slides, movies, and animations appear correctly?
