Preparing your video presentation

Step-by-step guide to a successful in-person oral presentation

Create your slide presentation

The most successful presentation slides are graphically rich presentations of your research that both highlight the main points and fill in the most interesting details.

Your presentation slides should include:

  • All slides formatted for easy understanding of the information on each slide
  • Explanations for each graph, picture, and table
  • Media file(s) embedded in your primary presentation as a slide, and bring a backup of all media files with you onsite.


The session computer will have the standard font sets included in Mac OSX, Windows 10, as well as PowerPoint and Keynote. Please refrain from using custom or purchased fonts, as these will not be available and may impact how your presentation looks.

Aspect Ratio

Please be aware that the meeting will be utilizing 16:9 aspect ratio projectors (widescreen) in all rooms. To utilize the full screen, you should create your presentation in “widescreen” format. The standard 4:3 format will work but it will not fill the entire screen when in presentation mode.

Media Files

LaunchPad supports any media file type, and once again there are no size limits. An important note- please bring all media files with you when you upload your talk, even if you’ve embedded them in your talk. While we can help with many aspects of your talk on-site, we can’t “fix” a missing media file.

Presentation File Types

Your session computer will run both Mac and Windows files natively. The computer has the following software installed.

  • PowerPoint for Windows
  • PowerPoint for Mac
  • Keynote (latest version)
  • Adobe Reader for Mac
  • Google Chrome for Mac

In PowerPoint, please save your file as a .pptx. Do not use .ppt, .pps, or other formats, as this will affect your file’s ability to open correctly. Also please make sure that your file does not have automatic slide advance timings.

Web Links and Online Presentation Formats

  • If your presentation is web based (e.g., Google Presentations), instead of using the upload portal below you may email the publicly accessible link to your presentation.
  • WarpSpeed will send you a confirmation email letting you know that your presentation is successfully uploaded and accessible
  • If you are using Prezi, your presentation should be downloaded for offline viewing and the zip file should be uploaded using this portal

LaunchPad accepts all file types except LibreOffice, and there are no file size restrictions. Should you require assistance with uploading or presenting, technicians will be available at Speaker Check-In and throughout the meeting rooms to help.

Upload your slide presentation

All in-person presentations are handled by our on-site presentation management system, LaunchPad. All presenters must upload their slide presentation to LaunchPad before going to their conference room. There will not be an option to use your own device. There are two ways to upload your slide presentation. Regardless of which upload option you choose, always bring a back-up copy of your slide presentation with you to your session onsite.

1. Upload in advance

Upload slides to LaunchPad

Advance upload deadline: 5:00 PM Pacific Time on Friday 30 July 2021.

2. Upload onsite at Optics + Photonics

Bring your USB device to Speaker Check-In at least two hours before your session begins, or the day before if presenting in the first morning session. Speaker Check-In located in Conv. Ctr. Room 11B.

Preview and test presentation onsite at Speaker Check-In

  • Visit Speaker Check-In and test your presentation at least two hours prior to the start of your session.
  • If you find a mistake, you may submit a revision
  • Speaker Check-In Location: San Diego Convention Center Room 11B
  • Speaker Check-In is open during registration hours

Present in person

  • Bring a back-up copy of your presentation file and any media files to your session
  • Arrive in the conference room at least 10 minutes prior to the start of your session
  • Locate the session chair for your session and check in with them so they know you have arrived
  • When it’s time to present, simply walk to the lectern and click on your name
  • If the person before you left their talk on the screen, press the big glowing “Refresh” button on the lectern, and that will clear out the screen and bring up the list of speakers for your session
  • Your talk will be live-streamed to participants who are unable to attend your talk in person, and then it will be published and viewable on demand

Audiovisual equipment in meeting rooms

  • Apple MacBook - supports files created on either Mac or Windows
  • LCD projection - 16:9 aspect ratio; 1920 x 1080 resolution
  • Lapel microphone
  • Audio connection from the laptop
  • Laser pointer and slide advancer

Publishing your presentation

  • To give full access to all presentations for in-person and remote attendees, SPIE will be publishing all presentations to be viewed on demand, as well as archiving all presentations in the conference proceedings in the SPIE Digital Library
  • The published version of your talk will be available on demand after you present live
  • We offer two options for publishing your presentation:
    1. You can submit a video presentation recording before the conference, giving you the liberty to remove any content from your talk that you are not allowed to publish (must be received by the deadline, ~3 weeks before the meeting)
    2. If you do not submit a video presentation recording, SPIE will publish the in-person recording of your talk (slide capture with audio, no video)
  • SPIE retains rights to distribute and market the official SPIE recording of the presentation and/or poster, but the presenter retains copyright of all presented content

Optional video presentation recording

All in-person speakers will have the OPTION to pre-record their presentation for publication (in place of publishing your live presentation).

  • By submitting a presentation video for publication, you can control what is available on demand and archived in the conference proceedings while having more liberty over what is presented live
  • This option is especially advantageous for authors who have content that they are not allowed to publish, but are allowed to present, as you will have the freedom to exclude that content from the video presentation recording that you submit for publication

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:

  • 15–20 minutes for contributed
  • 20–25 minutes for Invited
  • 25–30 minutes for Keynote

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 are not 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 – other file formats are not supported
  • You may find the following resources helpful as you develop your video:
    • - a third-party site for compressing a video file into an MP4 file
    • - a third-party site for testing your microphone or recording a voice-over file

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?

Submit your video

  • The contact author or speaker must be registered before uploading your video
  • Once the SPIE submission system is open, using any web browser, visit and sign into your account
  • From the Account Dashboard, look under "Submission and Review System" and click on the symposium link
  • Scroll down until you find your paper
  • Click on the Upload video link to submit your presentation video and follow the steps to upload your presentation video .mp4 file
  • Only the contact author can submit the presentation video. The contact author can assign a coauthor as the contact author via the submission system or by sending a request to (include your paper number in message)

What happens next?

  • The contact author will receive an email confirming we have received the video
  • SPIE will check the file for technical issues and notify the contact author if any revision is necessary
  • SPIE will publish the video presentation recording after your live talk concludes to be available on demand to remote participants and archived in the conference proceedings in the SPIE Digital Library
