# Adding participants on the fly
If the user list panel is displayed on the right side, you can quickly add participants by selecting them in the Users sidebar and drag them with your mouse into the conference settings area:
# Main
This section includes the settings for the conference name, route, ID, and PIN.
# Conference name
The event name, which is also used on the conference connection page. This name can be changed on the fly during the conference, but it will be restored to its original value when the conference ends.
# Route
Route is a mandatory primary identifier used for accessing the conference. It can consist of digits, Latin letters, hyphens, and underscores. By using the 
button, you can choose not to use the conference name as its route. For example, in the picture above, the route would look like this Conf_855958710. To generate a new value, click the 
button; if you need to clear the field, click 
.
# ID
ID is an additional conference identifier consisting only of digits. It is used for alternative access to the conference and for connecting via DTMF. This identifier is generated automatically when the conference is created, but it is not mandatory. You can delete it as described above.
# PIN
A conference can also be protected from unauthorized access with a PIN code. It consists only of digits. One can change the PIN of an ongoing conference. However, when the event ends, the previous PIN will be restored.
# Conference connection page
To let participants join the conference from TrueConf client applications, you can enable and share a link to the conference connection page. To do it, check the box Allow access to conference via link. For more details about the connection page, check the corresponding section.

Select the repetition mode in the pop-up window. Depending on the selected mode, various settings will be available:
Do not repeat – set scheduled date and time.
Weekly – the time and day(s) of the recurring meeting will also be specified
Monthly – the dates selected for recurrence will be specified.
Below you can find the example of a weekly conference repeated on certain days (meeting duration and validity period of the schedule are also included).
# Sending a conference Invitation
To send an invitation to the event, you need to:
Configure the SMTP gateway
Make sure that the invited participants have an email address added in their profile
Set schedule for the conference.
After this, the 
button will become active in the conference control panel; it will allow you to send an invitation.
# Layouts
Video layout configuration is available only for SIP and H.323 connections.
Video layouts can be set both when creating a conference and during the event. By default, the For all participants layout is created. It is received by all the participants who do not have their individual layouts. For example, the global layout will be received by the participant who joined the conference by ID.
To edit the video layout For all participants, click the button 
which is next to the layout name in the list.
You can create an individual video layout for one or more users. To do it:
Click the Add button.
A pop-up with the list of conference participants will open.
Select the users for whom you are creating the video layout, and click the Next button.
You will switch to layout editing mode.
# Editing a video layout
In editing mode, the main video layout settings are available in the General tab. Here you can:
Enable/disable the automatic video layout created by TrueConf MCU depending on the current number of connected conference participants.
Use overlapping video layout mode. In this type of layout, one of the video windows is expanded to fill the entire screen, while the slots of other participants are placed over it.
Set the number of available video windows.
Activate automatic rotation (alternation) of participants. This feature works if the number of participants is greater than the number of video windows.
When the automatic video layout is disabled, you will be able to select the type of layouts and access the layout constructor described below.
# Layout constructor
To use the constructor:
Disable the automatic video layout
Select the layout type:
Flexible — works with any number of video windows in the layout.
Predefined — works with a predefined number of video windows that cannot be changed (the number is specified next to the thumbnail).
3. Select the video layout, specify the number of video windows, and activate the overlay mode, if necessary.
4. Click Fill windows automatically or configure video windows as shown below.
# Manual configuration
Select a video window in the constructor menu. The settings window will be displayed on the right side. Choose one of the options in the Video window type drop-down list (various settings will be available depending on your choice):
Empty — an empty video window, for example, for a participant who might be invited during the conference
Fixed participant: one of the participants will be permanently displayed in the selected window
Active speaker — display of the participant who is currently speaking
The active speaker will be displayed in the video window only when voice activity detection is enabled. Available only in the General mode.
Autofill — automatically displays one of the participants. To enable automatic rotation of participants in this video window, check the Shuffle participants box. The rotation time can be configured in Administration → Video.
Content: the window will be used for displaying the content shared by participants, e.g., desktop or slides.
Only one video window can be selected for content sharing.
You can set scaling for each video window, if it is not of the Empty or Content type:
Crop video — this mode is intended for displaying the maximum number of windows in the layout.
Don’t crop video — in this mode, a participant's video is scaled to fit the layout windows. In this mode, the video is not cropped which helps to improve MCU performance when rendering the layout.
Auto: TrueConf MCU determines the best video scaling mode depending on the current resource usage.
Below there is an example of a general overlapping layout consisting of six video windows with all types represented.
After setting up the video layout, click the Save button to exit editing mode.
# Editing the layout on the fly
If you need to quickly change the current video layout, for example, to rearrange windows, you can do it by simply dragging one of the video windows in the constructor:
# Audio channels
In TrueConf MCU, you can split video conference participants into audio streams, each of which can be assigned a speaker or listener role. This option significantly simplifies the organization of events where simultaneous translation into several languages is required.
To create a new channel, press the Add button. In the window that appears:
Enter the channel name.
Add attendees and speakers.
Click the Create button.
# Design
By default, all conferences follow the layout style defined in Administration → Skin styles. To apply a different style for all layouts of a given conference, check the Enable custom settings box and customize everything as you see fit. Сheck the Customizaton section for more details on styles.
# Additional
In the Additional section, you can configure the settings of recording and video/audio transmission for the selected conference:
Enable/disable noise suppression and AGC
Select audio and video codecs to be used
Set the resolution, bitrate, and scaling mode
Specify settings for using participants' avatars in the video layout.
By default, values from the global call and video settings are used.
Disabling some codecs can solve compatibility issues with some SIP endpoints. To learn more about this question, please contact our technical support team.
# Recording of the conference and presentation
To optimize conference recording, you can select the quality:
Highest
Optimal
Minimum size.
You will also see the maximum duration of the video recording which will be estimated based on the available space in the video storage:
To configure presentation (secondary stream) recording or disable it, select the corresponding option in the settings (by default, the presentation will be recorded in full-screen mode):
