CERN e-learning project


This project aims at promoting features, tools and, mostly IT, services via very short videos - ideally not exceeding 5 minutes. These short informative and educational sequences can be recorded by the CERN audiovisual services and/or screen capture tools at the desk. Our aim is to provide tools and advice for content owners and/or users of the information to do this.

Tools' index

  • Project description here. It contains some Use Cases and Content owners.
  • e-group here. Members can be viewed.
  • vidyo portal here. It can be used for any meeting or rehearsal.
  • Indico category dedicated to e-learning here.
  • CDS category dedicated to e-learning here
  • CERN e-learning logo in progress. Request sent by Maria Dimou to the CERN designer Fabienne Marcastel on 2016/01/20. CERN decided to make a common logo for all such activities. Pending.


  • Teleprompter mirrorscript: A free-of-charge teleprompter on the web, easy to use, removes all speaker's stress to remember the text and pronounce it without hesitation.
  • Terminal recording tool asciinema: A simple to use from a terminal tool that records/replays what you type. Example thanks to Pedro Ferreira.
  • Screen capture tool ffmpeg: A free, open source and cross platform command line tool to make tutorials from your desk. Example thanks to Alexandre Racine (attached to this twiki).

Points for speakers' preparation and recording set-up:

  • Create an event in the e-learning indico category for every rehearsal to keep trace of the process and notes for future use.
  • Write down every word you plan to say. Attach it to the relevant indico event. Example the lhcathome tutorial's text by Karolina Bozek.
  • Give a structure to your text and say where you are s you go on, e.g. "This tutorial is about this cool feature... I'll explain what it does, how to install, how to configure, how to start, stop, monitor..."
  • Use a teleprompter (like a TV news' broadcaster). !! At least until the 50th rehearsal it is needed. This free-of-charge teleprompter on the web allows very esay upload of your text.
  • Rehearse, rehearse, rehearse. Use colleagues familiar with the domain as your public to obtain feedback.
  • Measure the time. Mini-tutorials should not exceed 5' to maintain audience attention. Dropping from 8' to 4' requires many rehearsals.
  • Check what is already available on the web, as examples to learn from.
  • Make sure everything you type in the video respects security rules. No personal emails, logins, passwords etc. The CERN IT recording team cannot edit video to blur text.
  • Avoid typing commands 'live'. Rather make slides, screenshots or web page tabs with the commands on.
  • If you have slides, select the 16*9 landscape format for the slide dimension.
  • Make sure the web pages of the application you present are clear for new-comers. Else, talk to their webmasters before recording the tutorial.
  • Browser and terminal windows should be in one of the CERN official languages. Starting point should be a CERN web page.
  • If you present a tool that works on multiple Operating systems, make a generic introduction and shorter episodes per Operating System.
  • The camera should show the speaker first with a CERN picture in the background and then the slides, web pages and command lines of the tutorial.
  • Display the tailor-made CERN logo before starting and at tutorial closing. A CERN e-learning logo is in preparation common to the whole organisation.
  • Make sure no items get in the video belonging to commercial brands (e.g. water or soda bottles). Laptops are fine.
  • Write "Do NOT disturb" on the door when recording to avoid people entering during your best try.
  • Use a normal chair (no wheels, not twisting) to minimise body movements during the video. Keep hands visible.
  • Screen capture tool and example
