CERN Academic Training lectures in YouTube

This project - completed in August 2018 - is about making our corpus of recorded Academic Training (AT) lectures more widely known via a dedicated CERNAcademicTraining YouTube channel. See the project description here

The implementation was discussed and agreed with the CERN Academic Training Committee (ATC), CERN Communications experts and the IT/CDA management (Example).

Concerning rights to publish the recorded lectures on the web, the Speaker's Release Agreement they signed covers this case.


The YouTube channel "CERN Lectures" was created on 2018-06-26 and the first video published was the Academic Training lecture of 2018-06-06 by Vint Cerf.

The video is in two playlists on the channel: "CERN Academic Training Lectures" and "Computing". The owner of the account is which links to a CERN egroup Members: K.Kahle, J.Fichet, M.Dimou, M.Domaracky.

The documentation on the video editing tool is here. Please send comments to Maria Dimou (editor).

Project phases

  1. Evaluation of other such videos: Done - see result in ArtAndScienceCoolVideos.
  2. Suggested good lecture series to use as pilot entries in the channel are below. Done - submitted to the ATC members - please say if you agree and if there are some that are OBSOLETE and others, not listed here, that MUST be there! Also, please send to Maria a list of keywords, per area, to facilitate searching in YouTube.
    1. Pilot list on Physics lectures.
    2. Pilot list on Applied Physics & Technology lectures.
    3. Pilot list on Other Disciplines lectures.
    4. A Playlist on Statistics. ATC members, what do you think on such playlists? Are all series in this list still worth publishing in YouTube?
  3. The blue CERN logo .mp4 was selected to wrap the video. The CERN IR Communications team agreed (J.Fichet & K.Kahle). Please find the Begin CERN logo and End wrappings with the logo.
  4. Additional functionality: We can get a transcript of all AT lectures' text and attach it to the SHOW MORE section. See how here.

Workflow for the automation

A script is being developed by 2018 Summer Student G.Tourpetas using the ffmpeg command option - see details here. The workflow was agreed in a meeting with J.Fichet, M.Domaracky, M.Dimou, G.Tourpetas on 2018-06-11.

  1. Insert the URIs of the High speed camera and slides channels of an AT video from CDS in the form (see mockup here). See points 2.1-2.4 above for candidate CDS records. Example: For Vint Cerf's lecture on 2018-06-06 click on Download -- More and take this for camera and this for slides.
  2. The script will convert internally the URI into the file path in \\\dfs\Services\MediaArchive\Video\Masters\WebLectures\YYYY\Indico_Event_number\[camera.mp4] | [slides.mp4].
  3. Insert the Begin CERN logo
  4. Define a time interval to only show the camera channel during speaker's introduction by the lecture sponsor.
  5. Define a time interval to only show the slides channel for the duration of the lecture, during which... EITHER:
    1. Introduce periodic appearences of the lecturer as a Picture in Picture (PiP) at a fixed interval (for 20'' secs every 100'' secs) Example OR
    2. Keep the PiP with the speaker throughout the whole lecture Example.
  6. Define a time interval to only show the camera channel during Questions & Answers.
  7. Insert the End CERN logo to close the video.
  8. The new video produced will be automatically saved in \\\dfs\Services\MediaArchive\Video\Masters\WebLectures\YYYY\Indico_Event_number\podcast_master.mp4
  9. Test for various devices, in particular the PiP rendering (check this and more for precautions).
  10. During the development: Keep a copy of the final version in the e-learning project space. Access allowed to the e-learning-interest-group and the atc-members. The script, when in production, deposits the output file directly in the right MediaArchive directory.
  11. In production: Open and follow the instructions in The output of the script is always written in a file in the format: \\\dfs\Services\MediaArchive\Video\Masters\WebLectures\YEAR\INDICO_EVENT_NUMBER\media\podcast_master_new.mp4.
  12. Open a SNOW request to audiovisual-support for replacing the mobile version in the published video version in CDS by the one created with AVEditor. See here how to clearly phrase such a ticket. It should be assigned to Webcast. See here the mobile version of the Vint Cerf lecture example mentioned above.
  13. Submit the output for YouTube publishing and inclusion in the CERNAcademicTraining playlist. This is done by email to K.Kahle. The keywords are put by M.Dimou in the Abstract field of the CDS record.

How to get a transcript of any video using YouTube

This video and the suggested lists of lectures above are made by Alex Manzoni - CERN/IT/CDA student in the IT e-learning project.
