Guidelines for Presenters

We are using Preseria to manage all on-demand video presentations for our virtual conference. Presenters should have received an email with information on how to

  1. Upload a video presentation (see instructions for recording below).
  2. Upload a profile picture (quadratic images works best).
  3. Submit a short biography (less than 600 characters).

Instructions for Video Recording

Videos should contain a prominent view of the presentation slides, along with audio of the spoken presentation, and a shot of the speaker’s head for increased engagement (this shot should be thumbnail-sized and overlaid on the slide images as shown here). Video clips or other visual presentation formats can also be included, but please plan to include a thumbnail view of the presenter speaking when possible. Many presentation software tools allow recording audio and video directly in the application and can export appropriate video files. Please see the notes below for detailed instructions for Microsoft PowerPoint and Apple Keynote. Another possibility is to use Zoom’s “Local Recording” to record yourself sharing your screen and talking. Make note of where the video file is saved if prompted in a dialog. Zoom recordings are saved in a folder named “Zoom”, usually located inside your “Documents” folder.

Microsoft PowerPoint
  1. Follow these instructions to add audio (and optionally video) to your slides.
  2. Follow these instructions to generate a MPEG-4 (.mp4) file from your slides and audio/video.
  3. Alternatively, you can follow this video tutorial which goes through both of these steps
Apple Keynote
  1. See this video tutorial

Video file format

The presentation video must be in MP4, M4V, MKV, MOV, MPG or AVI format, with a resolution of 1080p HD or 720p HD. The video must not be longer than 15 minutes and its file size can not exceed 500 MB.

Tips for recording:

  1. Use as quiet an area as possible
    1. Avoid areas that have echo. Rooms should be fairly small
    2. Sound dampening can be done with carpeting, curtains, furniture
  2. Hardline internet connection recommended, but if unavailable, use a strong Wi-Fi connection
  3. Good headset with microphone close to mouth BUT away from direct line of mouth to reduce “pops”. Avoid using default built-in microphone on computer.
  4. Do a test recording of a couple of minutes and review the sound and picture quality, video format, and resolution before recording the entire presentation. Make adjustments if needed.
  5. You can download free software for re-encoding your video from https://handbrake.fr to adjust bit rate, resolution and format. Lowering the values will reduce the file size.
  6. You can trim and edit your video using the Photos app on Windows or by using iMovie on your Mac.
