-===== Record a video conference =====
+===== Record a Meeting =====
-==== Do Not Use BBB Recordings! ====
+==== Important to Consider ====
-There are multiple reasons why recording videoconferences is not a good idea:
-  * Availability: **You will not be able to download BBB recordings!**
-  * Personal and privacy-related reasons: you will need explicit consent from everyone every time.
-  * Environmental reasons: video files are huge!
-  * Technical: BBB will set 1-hour limit to all video-calls if recordings start to take too much space on HfG servers. This includes seminars that are not being recorded.
-Despite all these, in some fringe cases, it could be useful to record BBB sessions.
+There are several reasons **//not//** to record video conferences:
+  * Data protection: you need the explicit consent of all participants every time.
+  * Video files are very large. Especially for longer seminars or conferences, they become huge.
+  * Recordings on the server may be deleted if the available server capacity is exceeded.
+Nevertheless, in some cases it may be useful to record a BBB conference.
+==== Consent ====
-==== How to Record a Meeting ====
-=== Consent ===
 First and foremost, **you need to inform __all participants before recording__ and get their __explicit consent__** in order to hit the Record button. You must also state for how long and for what purpose you want to record. Beware: General Data Protection Regulation (GDPR) and other legal frameworks apply.
-If you fail to obtain explicit permission from a single participant, the recording must never begin. Participants do not need to explain or reason why they do not comply with recording and must not be forced to voice out such reasons under any circumstance, although they are of course welcome to do so if they find it appropriate.
+:!: //If you fail to obtain explicit permission from a single participant, the recording must never begin.//
-=== Technical Resources for Recording ===
+Participants do not need to explain or reason why they do not comply with recording and must not be forced to voice out such reasons under any circumstance, although they are of course welcome to do so if they find it appropriate.
-If you follow the above guidelines for consent, then you are allowed to record the session. Because it is strongly advised against using the BBB recording function, here are some screen-recording tools that you can use in different platforms.
+==== How to Record a Meeting ====
+If you follow the above guidelines for consent, then you are allowed to record the session.
+  * Start a room and click on 'Start recording' at the very top
+  * Confirm the recording
+  * A counter will start of the time recorded
+  * Eventually, stop the recording and end the meeting
+  * Your recording will be available in your BBB Homepage, **but not immediately!**
+BigBlueButton will immediately start working in the background to process your video and make it available to you on your BBB Home Page, but this will take time. The longer the video, the longer it will take to process; this could range from minutes to several hours and potentially even a whole day.
+{{:en:00.png?1000|Fig.6 Previous recordings show in your BBB dashboard}}
+===== Editing a Recording =====
+Once you recorded a BBB-conference you might want to share it with the participants or even publish it.
+:!: //Always make sure that you have explicit **consent for publication** from all participiants. Otherwise the recordings must not be published.//
+Technically a BBB recording consists of several components:
+  * Video(s) of the individual participants with audio track
+  * Presentations
+  * Public chat
+These components of a session are stored separately on the server. Their views can be changed individually by the participants during the course of the conference.
+When a recorded session is opened in BBB, these different streams are merged again at runtime. During playback, the viewers have the possibility to change the presentation (e.g. set it to full screen, hide it, etc.). This means that the conference was not stored on the server as ONE video file that could be downloaded.
+This leads to two possibilities for editing a recording:
+  - Download the video files individually and arrange them afterwards with an external tool (video editing).
+  - Play the recording in the browser and record your screen with a screen capturing tool.
+==== Two Variants ====
+Download individually:
+  * Chat not available
+  * Video editing tool required (and knowledge)
+  * Videos can be freely arranged
+  * Individual post-editing possible (e.g. sound)
+Screen capture:
+  * Chat available
+  * Screen recording tool
+  * Live arrangement during runtime
+  * Only post-editing of the entire recording
+  * Duration of screen recording = duration of recording
+==== Variant 1: Download Video Files Individually ====
+After a video conference has been recorded, BBB stores two individual videos on the server:
+  * Webcams
+  * Presentation
+These videos must be downloaded and merged (edited) using a video editing tool.
+:!: //The chat history cannot be downloaded. It is not available when using this method. If you need the chat history to be part of the recording, please use method 2.//
+=== Download Videos from the BBB Server ===
+The BBB recording can be accessed in the browser via the start page of the room in which the video conference took place.
+The recording consists of two windows that can be played simultaneously (→ Play button). Webcams and presentation are individual video files.
+For this method we have to download the two video files individually. First, move the mouse over the webcam video. With a right click in the browser ( Firefox in this case) a menu appears. Click ''Save video as...''
+{{:en:02.jpg?600|Fig.7 Download a video by right-clicking and selecting ''Save video as''}}
+Choose a folder where you want to save the video file.
+{{:en:03.jpg?600|Fig.8 Name and save your BBB recording}}
+Repeat this process for the second video: Move the mouse over the presentation video, right-click and select ''Save video as...''
+After a successful download, you have saved both videos on your hard disk. In the next step you can import them into the video editing tool of your choice and arrange them.
+==== Variant 2: Screen Recording ====
+As described above, the individual streams can be arranged in the browser while the recording is running. Therefore, screen-recording should only be done with someone present who will follow the conference attentively and, during the course of the recording, zoom in on the presentation when it should be in the foreground, etc.
+Here are some screen-recording tools that you can use in different platforms.
+=== OBS Studio (Open Broadcaster Software) ===
-== OBS Studio (Open Broadcaster Software) ==
 We recommend OBS Studio, a free and open source software that works on all computer operating systems: Windows, Mac, Linux, FreeBSD. It is feature-rich and has both a good knowledge base and an active community to help you learn to use it in depth. You can download it from their webpage, https://obsproject.com/.
 If you want a //quick fix//, a simpler tool that “just works”, below are some alternatives for each platform.

 Kazam: streamlined and extremely simple to use, it is available through [[https://launchpad.net/kazam|Launchpad]]. Here you can find a simple, [[https://itsfoss.com/kazam-screen-recorder/|step-by-step guide]] for installing and using it in Ubuntu.
-== Mac ==
+=== Mac ===
 The simplest way is to use the built-in application Quicktime Player:
   * Launch Quicktime

   * Hit 'Record'!
-== Windows ==
+=== Windows ===
 Windows 10 has a built-in recording feature but it is a bit hidden. It is built into the 'Game Bar' application. [[https://www.pcmag.com/how-to/how-to-capture-video-clips-in-windows-10|Here you can find a guide]] on how to open, configure and use it. [[https://www.techsmith.com/video-editor.html|Camtasia]] and [[https://www.bandicam.com/|Bandicamp]] are other popular options.
-== Mobile Devices (Android, iOS) ==
+=== Mobile Devices (Android, iOS) ===
 Modern versions of both iOS and Android have built-in screen recording capabilities. If you have Android 11 or over, have a look at the [[https://support.google.com/android/answer/9075928?hl=en|official Google documentation]]. If you have iOS 13 or over, have at the [[https://support.apple.com/en-us/HT207935|official Apple documentation]].

 For earlier versions of iOS, popular apps available via the App Store are 'Record it!' and 'Go Record'.
-==== When and How to Use a Recording ====
-If you need to record a specific session for a few days, without further archival or post-processing features, then BBB Recordings can be used.
-  * Start a room and click on 'Start recording' at the very top.
-  * Confirm the recording.
-  * A counter will start of the time recorded.
-  * Eventually, stop the recording and end the meeting.
-  * Your recording will be available in your BBB Homepage, **but not immediately!**
-BigBlueButton will immediately start working in the background to process your video and make it available to you on your BBB Home Page, but this will take time. The longer the video, the longer it will take to process; this could range from minutes to several hours and potentially even a whole day.
