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
- Oral Presentation: Maximum duration of 10 minutes
- Video Presentation: Maximum duration of 8 minutes
- Invited Oral Presentation: Maximum duration of 15 minutes
- Format: MP4
- Dimensions: Minimum height 480 pixels
- File size: Maximum 100 MB
- Aspect Ratio: 16:9 (widescreen format)
Tips for recording
- Check that your final video and audio plays directly in common web browsers like Chrome/Chromium, Firefox, etc. by dragging the video file onto a browser window. You may need to re-encode the video file with different parameters if there is no audio or video portion played on the web browser.
- Use as quiet an area as possible.
- Avoid areas that have echo:
- Rooms should be fairly small;
- Sound dampening with carpeting, curtains, furniture.
- Hardline internet connections are highly recommended, but if unavailable, a strong Wi-Fi connection should do the job.
- 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.
- 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.
Uploading Your Presentation Video and other Media Files
In addition to the video presentation, GNSS+R 2021 allows authors to upload other types of media to be used with the virtual presentation.
||An MP4 video (Regular Oral: 10 minutes; Video Presentation: 8 minutes; Invited Oral: 15 minutes) of your presentation. Please read the Video Preparation Instructions above for more detailed formatting requirements.
||A text transcription of your video presentation, following the WebVTT format. If provided, this will be used to enable the closed-caption feature in the video playback. Create a WebVTT file at https://www.vtt-creator.com/
||A single photograph of the presenter or authors. Dimensions should be no larger than 1024 pixels in either height or width, and should be in PNG or JPEG format only.
||A PDF or Powerpoint file containing your slides used in the presentation.
Only ONE file of each type may be submitted. New uploads will REPLACE existing uploads of the same type.
Authors will be required to electronically sign a Consent and Release statmement, which grants the conference the permission to receive, display, and archive the media files submitted for use during the virtual conference.
