# Collaboration tools

# Chat

Instant messaging (or chat) allows users to exchange text messages or files during video calls or group video conferences. You can use chat not only during video calls or conferences, but every time you need to send a message to other users.

If you sign in on a different device, your previous chat history won’t be available.


# File sharing

To send a file simply drag and drop it to the chat panel. Alternatively, you can click on the paperclip icon on the left side of the input field.


Click to select a file (it will be sent to the chat immediately without prior confirmation).

If users are not currently online, you can send them an offline message, they will get it immediately when they are online.

The default location of downloaded files is:

  • C:\Users\User_Name\Downloads for Windows

  • /home/User_Name/Downloads for Linux

  • /Users/User_Name/Downloads for MacOS.

To change the download folder, go to Settings → Preferences → Tools menu in the application window. Then click the /client/media/gui/file_save_button/en.png button in the File Transfer section and specify the required folder.


If you want to open the files sent to the chat, click on the chat avatar and choose Files.

# Conference recordings

If other participants allow, you can record your conferences.

# How to record video conferences

During a call or conference, click on the button /client/media/gui/conference_tools_button/en.png and choose Video recording. In the pop-up window, click /client/media/gui/record_object_button/en.png in the upper left corner to select the recording source, specify the conference participants you want to record (all, only yourself or someone else) and click /client/media/gui/record_button/en.png.


Each recorded conference participant will see the icon /client/media/gui/recording_icon/en.png in the upper left corner of their video window.

In this case, the user who is recording the meeting will see the button /client/media/gui/recording_button/en.png at the bottom of the video window. Click on this icon to open the conference recording window.

If you are recording a video call or a conference from your client application and want to include the content being shared during the meeting in your video recording, use the Screen sharing tool. Share your screen or a separate application window. The shared content will immediately appear in the recording instead of your webcam video.

Please do not place the content in a separate window: in this case it won't be recorded.

# How to configure permissions for conference recording

Each participant can configure permissions for conference recording individually (to do it, proceed to Settings → Preferences → Tools → Video Recording, Who can record me field in your client application).


Possible settings options:

  • Nobody. Your video window cannot be recorded.

  • Ask me each time. Before recording starts, a conference participant will get the following request:


If granted, the permission cannot be revoked. Recording will stop only when you leave the conference.

  • Users from my Address Book. Automatic recording of your video window is allowed for your address book contacts, while other users will have to ask for permission.

  • Everyone. Automatic recording of your video window is allowed for everybody.

# How to find conference recordings

By default, video conference recordings are saved in .mp4 format to the Videos folder on your PC. This folder can be found in your profile folder by following the path given in the Video Recording section, Settings → Preferences → Tools.


# Selecting recording options

You can record video conferences in different formats and with different parameters. By default, recordings use .mp4 format, but you can choose another one in the available formats: .avi and mkv. You can also change the video recording resolution, but keep in mind that the maximum resolution depends on your computer performance and may vary from device to device.

If you uncheck the Show participants' names in the recording box, the recording will not contain user names.

# How to watch conference recordings

You can watch recorded conferences on your PC using any video player (such as VLC) that supports VP8 codec.

# Slideshow

During video conferences, participants can not only hear and see each other, but also share content or show slides.

Importing slideshows from ppt and pptx files is available only in TrueConf for Windows and requires Microsoft PowerPoint preinstalled on your computer.

TrueConf for Android and iOS users can use the content sharing feature.

# Supported formats

You can import slideshows in the following formats: ppt, pptx, slides and pdf file pages.

You can also create a slideshow from your pictures right in the application or add some pictures to the list of the slides imported from a slideshow or a PDF file. For images, you can use jpeg, png, gif formats.

# Opening a PDF file

To import PDF file pages into a slideshow, click on the button /client/media/gui/open_pdf_button/en.png when creating it.

To use PDF files, you must have the Ghostscript plugin installed in the system.

If it is not installed, you will see the Framework settings window when trying to import the file. Click on the Install button to automatically download the required plugin.

# Content sharing

During conferences, you can share your screen or separate windows using TrueConf client application.

Your content will be visible to all conference participants connected via TrueConf client applications and browsers (using WebRTC technology). Besides, the content shared during the conference can also be recorded for future reference.

Only maximized windows are correctly displayed during content sharing. Minimized windows will not be shared.

To switch to sharing content during a video call or group conference, click on the button /client/media/gui/share_content_button/en.png in the control panel.

Select the screen or application you wish to share in the drop-down list.


After that the application window will be minimized and the control panel will appear in the right bottom corner of the screen. This window will be displayed on top of all windows during the whole sharing period. Other conference participants will see your self-view video instead.


The content control window contains the following elements:

  • The shared screen/application name is located in the window title

  • /client/media/gui/view_content/hide/en.png button to minimize/expand the widget
  • /client/media/gui/view_content/move/en.png area to move the widget
  • /client/media/gui/view_content/end/en.png button to disable content sharing: the minimized application window is maximized in one click
  • /client/media/gui/view_content/mode/en.png button to set up content sharing: select the source and self-view settings
  • /client/media/gui/view_content/video/en.png button to select an image to be shown in the preview area (available only when the screen is shared)
  • /client/media/gui/view_content/control/en.png button to view the list of participants who gained [remote control over your desktop](#desktop-control-settings) during a conference (here you can disable this option)
  • /client/media/gui/view_content/more/en.png button to switch to the additional conference controls

By clicking on the button /client/media/gui/view_content/mode/en.png and selecting Show my video and content in separate windows, you can share content with conference participants as a separate stream. This way, the shared content can be viewed on third-party video conferencing endpoints (via BFCP/H.239 protocols).

# Sharing multiple screens

During a meeting, multiple speakers may share their screen or separate application windows. In this case, participants have a useful option to switch between the screens or move the video window to an additional monitor so that they don't miss a single detail.


# Remote desktop control

During video meetings, you can take control over the desktop of the participant who is sharing the content.

To this end, click on the mouse icon /client/media/gui/mouse/en.png at the right edge of its video window.

After you have been allowed to control the desktop, the control panel will appear in the upper-right corner of the video window:

  1. Collapse / expand the panel

  2. Finish the remote control session

  3. Keyboard input emulation

  4. Display remote desktop control window in full screen.

# Configuring access to your remote desktop

You can set up remote desktop control policies in the client application settings: enable all users in your address book to access your remote desktop, disable users to access your remote desktop, or enable users to access your remote desktop on request.

To do so, go to Settings → Preferences → Tools and choose a corresponding option in the Who can access my desktop field.


Ask me each time is a default setting; by selecting this option, you will be notified when someone tries to access your desktop control:


The notification will be visible for 100 seconds after which the user who has requested access will see the following message:


# Can multiple meeting participants take control over your desktop simultaneously?

Several conference participants can request access to control your desktop. In this case, the button /client/media/gui/view_content/control/en.png will become active in the content control window.

Click on this button to grant access to one or several participants, or deny requests:


# PTZ camera control

During conferences, you can rotate and zoom users' PTZ cameras (including cameras of video conferencing endpoints).

You can control conference participants' PTZ cameras only if you are a conference moderator.

# How to manage access to my camera

By default, PTZ camera control is available on request. This means that if you attempt to control a camera, its owner will see the notification about the request to take control of their camera.


In client application settings, you can disable this option. You can prohibit sending requests (thereby making your camera unavailable for external control) or allow all users to access your camera in one click without having to ask for permission.

To do this, go to Settings → Audio and Video → PTZ camera control, choose one of three options under Who can control my PTZ camera heading: Ask me each time, Everyone or Nobody.


# How to control other users' cameras

To control the camera, click on the button /client/media/gui/control_ptz/en.png in the user's video window or right-click on the video window and select Control camera in the pop-up menu.

If a user enabled Ask me each time in camera control settings, the application will prompt you to send such a request. The user will receive a notification about your request.

After you have been granted access, the camera control panel will appear in the center of your video window.


When closing the panel, click on the button /client/media/gui/control_ptz/en.png in the user's video window to return the camera control window.

# How to control my own PTZ camera

If you have selected a PTZ camera in the client application, the /client/media/gui/control_ptz/en.png icon will appear in the corner of your video window. By clicking on this icon, you will open the camera control panel.
