Scheduled recordings and live streaming in classrooms

Some auditoriums are equipped to film a lecture or conference from the control room. This stream can be broadcast live.

Schedule recordings

Available auditoriums: BCH 2 201, CE1, CE3, CE4, CE6, CM3, CM5, CO2, CO3, Rolex, SG 1 and STCC C, as well as CM1 and CM2 since Fall 25.
The CO1 lecture hall is no longer in service due to the ongoing Double Deck project.

Request the scheduling of a recording in advance using this form. When the request is validated, recording is automatically triggered at the requested times and dates. The videos are found in the ‘my media’ space of the persons who made the request. They can be then manually or automatically broadcast (publish) in their dedicated channel.

The recording is valid for a whole semester: if an unforeseen event happens, please notify [email protected] well in advance (minimum 24 working hours).

Recording Settings

Each recording includes two streams:

  • the room camera, which films the whiteboard
  • the connected computer (the slides)

These two streams do not have the same status: one is defined as the parent and the other as the child. The parent stream appears larger in the video (and live streaming) and benefits from higher quality. This relationship is managed directly by the room’s recorder (Extron recorders of various generations), not via mediaspace.

  • The choice of the parent stream is predefined and cannot be changed in rooms BCH 2 201, CE1, CE3, CE4, CE6 and STCC C.

  • In rooms CM1, CM2, CM3, and CM5, it is possible to select the parent (main) stream at the beginning of the class via the touch panel.

  • Once the recording is finished, you can send the URL of the video to [email protected]  either to swap the streams in the combined video or to delete one of the two streams.

 

Live streaming of the lectures

It is possible to stream a course. Students can follow the course virtually, but with a one or two minute delay, and without the possibility of interaction (chat, questions, etc.).
The ‘live’ stream is an option to choose when scheduling  the recording. It is not possible to modify this parameter from one course to another, live streaming is valid for all sessions.

Room CM3

This room is equipped with a screen that allows you to act on a scheduled recording:

  • On the auditorium touch screen, choose the “recording” menu then “start kaltura recording”
  • Enter your Sciper number (ID B = your Sciper number)
  • Click on “start recording”
  • At the end of your lesson, press “Stop” and confirm that the recording has stopped.

Use the microphones in the room carefully. A screen displays the two video streams that are recorded. The recordings are then available on the mediaspace.epfl.ch platform (log in, go to ‘my media’, then publish the videos in the relevant channel).

If you have technical issues about the system, contact the audiovisual department SAVE.

What to do if you are not in one of these auditoriums ?

You can use the Kaltura Capture module from mediaspace.epfl.ch with your own computer. But the quality of the recording is not guaranteed, it depends on the local parameters of your machine (available bandwidth, RAM, etc.)

To install Kaltura Capture, please download the latest version from the provider’s official page.

You can also use Zoom, then upload and publish your videos to mediaspace.epfl.ch later.
