Based on the current pandemic situation and further projections, we have decided to hold a virtual conference in April 2021.

8th European Conference on Space Debris

Instructions for recording presentations

Please note: There are two supported ways for creating and uploading your recording. Using the provided web based recording tool is highly recommended unless you have specific needs (e.g. PowerPoint animations that you cannot convert into an embedded video or recording multiple presenters).

Web based recording
  • No software installation needed
  • Easy to use
  • Enforces correct video format and overlay placement of the video showing the presenter
  • Both PPTX and PDF files supported
  • Supports embedded MP4 h.264 video clips within PowerPoint files
  • Best recording quality
  • PowerPoint animations are not supported (Note: If PowerPoint animations are needed, they could be recorded as a video and inserted into the slides as a video file)

Option 2: Recording without the web based recorder
  • Most flexible
  • Use of PowerPoint animations 

 

General recording instructions (either option 1 or 2)

  • Whether you use recording option 1 or 2, the recordings should look like "live recordings" - that is, recorded in one piece. Therefore, in the web-based recording tool, it is not possible to pause and resume the recording. 
  • The recording should not be longer than 15 minutes. During the live session at the conference, after the transmission of your pre-recorded presentation, as a default 3 additional minutes will be given for moderated questions and answers. If you would like to allow more time for the Q&A session, you will have to shorten your presentation accordingly, so that the total allocation of 18min is not exceeded. Note that the presence of you or a presenting co-author at the indicated time in the conference schedule is therefore mandatory for oral presentations.
  • Presentations should start immediately at the beginning of the recording and stop right after the presentation ends.
  • Using a wired headset is strongly recommended to avoid any body-borne noise using the built-in microphone, such as keystrokes, clicks on trackpad and fan noise.
  • Ensure sufficient lighting conditions
  • Use a neutral background if possible
  • The camera should ideally not be lower than your eyes
  • Enable “do not disturb mode” on your device to avoid audio notifications
  • Close all other applications before you start the recording

Preparation of your PowerPoint or PDF presentation (either option 1 or 2)

Only presentations with 16:9 aspect ratio are accepted.

During recording, a camera overlay showing the presenter will be positioned in the bottom right corner of the slides. You have to make sure that there will be no overlap with presentation content and keep free a rectangular area. This area for the overlay must have a 4:3 aspect ratio and the following dimensions:

  • width: 18% of document width
  • height:  24% of document height

The web based recording tool provides an indication where the camera overlay will be placed during playback. Please check with a test recording whether the overlay of the presenter video fits to your presentation slides.

Using the web based recorder (Option 1)

Prerequisites and limitations:

  • Only recent desktop versions of Google Chrome are supported (version 66 and above)
  • Mobile devices and devices in portrait orientation are not supported
  • Do not use „incognito tabs“
  • Maximum allowed size for PDF files is 25 MB
  • Maximum PowerPoint file size is 25 MB without embedded videos (100 MB including videos)
  • At most one video per slide is allowed
  • First slide must not contain an embedded video

Create and submit your presentation recording:

Note: Recordings can be created and submitted until 31 March, 2021.

  1. You can access the recording and submitting tool for the presentations via your submitter account (camera icon / “add recording”).
  2. Clicking on the link will load the recording tool and start a quick introduction on how to use the tool
  3. Select your PDF/PPTX file with your slides for upload
  4. Start recording your presentation (Note: the presentation should not be more than a maximum of 15 minutes. If the recording is exceeding the limit, the recording tool will stop automatically). During the live session at the conference, after the 15-minute presentation, three minutes will be left for questions and answers. If you want to allow more time for the Q&A session, you will have to shorten your presentation accordingly.
  5. Check your recording with the tool’s player
  6. If you are not satisfied, you can start a new recording. The old recording will be overwritten and not be saved.
  7. If you want to use modified slides, you can upload a new PDF/PPTX file. The previous recording will be deleted.
  8. Submission: If you are satisfied with your recording, you can upload your recording to the conference system.
  9. You will then receive a confirmation email for the submission of the presentation. This will include a link to watch the submitted video again. Please check the video for possible transmission errors during upload. If this is the case, please contact the conference office (contact@space-debris-conference.com).

Note: 
You can create new recordings and upload them to the conference system until the deadline (March 31, 2021). The previous version will be deleted (reverting back to an older version is not possible).

You can take as many recordings attempts as you like. A recording previously submitted to the conference system will not be overwritten until you submit the new recording to the conference system
 

Produce a recording without the web based recorder and upload as video file (Option 2)

The recording tool can also be used to upload your self-produced presentation recording in MP4 format.

During the live session at the conference, after the 15-minute presentation, 3 additional minutes will be given for questions and answers. If you want to allow more time for the Q&A session, you will have to shorten your presentation accordingly.
  • We recommend a camera overlay showing the presenter in the bottom right corner of the slides. You should make sure that there is no overlap with the content of your presentation and that a rectangular area remains free.
    • Width of camera overlay should be 1/6 width of presentation (320px width)
    • Camera overlay should be in 4:3 aspect ratio (240px height)
    • Bottom right corner of camera overlay should be positioned as follows:
      • Distance from bottom: 0.7% of video height (~8px)
