In order to maximize the exposure for your paper, to account for different learning and participation styles, and to allow for interactive and engaging discussions with fellow attendees, each paper will be presented in several ways:
- Live presentation through Zoom, with scheduled time (zoom link will be sent via email), and
- Pre-recorded video that will be available at all times during the conference and will also be available afterwards on the SCDM Website
Kindly upload your pre-recorded presentation video before 28 May 2022.
Due date: May 28, 2022
The instructions for uploading the video are as follows:
Pre-recorded Video Instructions
The idea behind the pre-recorded presentation video is to provide attendees with a way to gain some insight into your contributions that is engaging, but does not require live interaction. This video will be posted within your assigned session on the SCDM 2022 on-demand online platform, and will subsequently be made available through the SCDM Website.
We are aware that each of you may have a different idea on how best to engage your audience, and we are happy to provide you with some flexibility to explore that. However, we are also aware that guidelines will be helpful to ensure a uniformly excellent experience for all. With that in mind we would like to establish the following minimum expectations:
- A brief introduction on a web cam, followed by
- A voice over slides presentation
There are a number of ways in which this minimum expectation could be enriched, and you are encouraged to consider them. These include having a video of the presenter in the corner of the slides, including animations that illustrate the concepts that underlie the work, including videos of practical implementations, and incorporating other techniques associated with the best practices of online pedagogy. If you would prefer not to include the brief on-camera introduction, we will understand.
We are also aware that each of you may have a different idea on the optimal duration of a pre-recorded video for the purposes of engaging online attendees with your work, and we are also happy to offer you some flexibility to select the length. However, our expectations are that your presentation video will be:
- A minimum of 5 minutes in duration, and
- A maximum of 15 minutes in duration.
The technical requirements of the video are as follows:
- Duration: At least 5 minutes and at most 15 minutes. Within that interval, choose a duration that you feel will best engage your audience
- File size: 100MB max
- Video file format: mp4
- Dimensions: Minimum height 720 pixels, aspect ratio: 16:9
Please note the final specifications will be checked at the time of submission and files not compliant may not be uploaded.
Please be sure the video includes the title of the paper, the authors, and a mention to SCDM 2022.
Tools for preparing the video
You can prepare your video using any recording and editing tool that will produce an output that will meet the above specifications. One simple way to record the presentation would be to use a video conferencing tool to record the content displayed by your computer screen and your voice recorded by the computer microphone, or an external microphone. In that way, you can show your face via webcam and display your slides as you talk. You can use any meeting software, as long as you get a good quality recording and your final file is in the MP4 format. Based on our experience, we recommend the use of Zoom, but the choice is yours. You may wish to edit the video after having recorded it. Here are some links to instructions on recording a meeting on common platforms:
- WebEx: Video Conferencing – Record a Cisco Webex Meeting
- Skype: Skype for Business: Recording a Meeting | Information Technology Services | Bemidji State University
- Google Meet: Record a video meeting – Meet Help
- Zoom: Local Recording – Zoom Help Center
- Gotomeeting: How to Record a GoToMeeting Session | Techwalla and How to Convert and Open the GoToMeeting Recordings
- Microsoft Teams: Record a meeting in Teams – Office Support
- Use of the free software OBS, which allows also to capture simultaneously yourself while speaking and your slides: https://obsproject.com/
In the case that your video size is exceeding the maximum file size, you can compress the video using the following tools:
- FreeConvert online video compresser: https://www.freeconvert.com/video-compressor
- Clideo online video compressor: https://clideo.com/compress-video
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.
- Show no more than 1 slide per minute of speaking time. This means approximately 10-15 slides MAXIMUM for the 15 minutes presentation. Remember, the last three minutes of the presentation are for questions from the audience. It detracts from the quality of the presentation to flash numerous graphs, equations, or tables on the screen in rapid sequence in an effort to squeeze a presentation into its allotted time.
- We recommend a presentation format of 16:9, 4:3 is also acceptable.
- Make the letters on your slides BIG ENOUGH. Suggested minimum font is 14.
- Put no more than 12 lines of text or 4 curves on any slide.
- Avoid lengthy tabulations of numerical data and limit equations to those for which the terms can be properly defined.
- Your audience needs time to interpret the data that you present. While you are very familiar with the data displayed, the audience is not. Describe the abscissa, coordinates, units and the legend for each curve.
- When you display a curve, tell the audience what they should be looking for in order to grasp the point you are trying to make. The audience will not have time to figure it out for themselves.
- Use repetition in your talk to ensure the facts are understood by the audience.
- In addition to the body of the talk, present an introduction and a summary or conclusion.
- Include only information or data that can be properly explained in the allotted time.
- Repeat any questions that are posed to you.
- If a question requires a lengthy reply, suggest that you and the person asking the question meet after the presentation. Then take the discussion out of the meeting room.
