Virtual Symposium: Video Preparation Instructions

Related Links
  1. The technical program will be organized similarly to a regular conference, but each presentation will be pre-recorded and will be played back in a live video stream on a defined schedule. Attendees may join the stream, watch the presentations, and submit questions to the speakers. The speakers will answer the questions during the live video stream event. The presentation videos will also be available before and after the live video stream. These are the official submission instructions for all presentations:
    1. Please plan to submit your presentation as soon as possible after you register and NO LATER THAN 10 July 2020. This submission deadline cannot be extended.
    2. Your presentation will be made available only to registered Symposium attendees for a limited period of time, beginning 21 September 2020 and ending on 9 October 2020 (one week after the symposium ends).
    3. Symposium attendees will be able to pose questions to authors either through an online discussion forum, or during the live stream.
  2. There are several tools available to easily record a presentation.

    The simplest is to create a Voice Over PowerPoint presentation:

    and convert it to MP4

    Alternatively, you can use a software suite such as Camtasia to achieve a similar result.

    Finally, you can use any meeting software, as long as you have a recording of good quality and your final file is in the MP4 format. Here are some links to instructions on recording a meeting on common platforms:

Audio/Video File Requirements

  • All files must be in MP4 Format
  • Duration: Maximum 5 minutes
  • Arrangement: Your voice, over 4-5 slides
  • Format: MP4
  • Dimensions: Minimum height 480 pixels
  • File size: Maximum 100 MB
  • Aspect Ratio: 16:9 (widescreen format)

Tips for recording

  1. Use as quiet an area as possible.
  2. Avoid areas that have echo:
    1. Rooms should be fairly small;
    2. Sound dampening with carpeting, curtains, furniture.
  3. Hardline internet connections are highly recommended, but if unavailable, a strong Wi-Fi connection should do the job.
  4. A good headset with a microphone set close to your mouth BUT away from direct line of mouth to reduce “pops”. Try to avoid using default, built-in microphones on your computer, if possible.
  5. Do a test recording of a couple of minutes and review the sound and picture quality, in the MP4 format, and check the bit rate before recording your entire presentation. Make adjustments as needed.
