What you need to know
You can use the "Screen share" feature with alfaview to share a section of your desktop with other participants.
Presenters can use this feature by default, as a participant you need VIP rights to use it. For more information on how to assign VIP rights, please refer to
What you have to do
Share selected areas or applications by clicking on "Share content" ().
A submenu with four options opens.
You have the choice between "Application", "Region share", "Screen" and "Second camera". (If other screens are connected, they will also be listed in the selection menu).
Application: if you have a program open that you want to share with participants, click the "Application" option and select a desired program from the list.
Screen: if you choose this option, the entire desktop (full screen) of your connected monitor will be filmed.
Region share: select a desired area of your desktop by scaling and moving the window, and then click "Start".
The desktop transmission starts. (Recognizable by the changing color of the window from blue to red and the changed title "Live").
If you subsequently move or scale the window, the transfer is paused for this period until you release the window again.
Be careful not to film the area of the video image transfer in alfaview, as in this way you will create an optical duplication of the video material, a kind of infinity effect.
Avoid the PowerPoint presentation setting Full Screen mode. Better choose windowed mode so that you can keep control of what's happening in the online lecture room during your presentation.
To start PowerPoint presentation with animations in window mode, click on "Set up slide show" and select the option "View through a single person (window)" there. In this mode, animations are output and you can use the drawing tool. However, you will not have access to the notes area.
Alternatively, you can leave the PowerPoint presentation in "Edit mode" and thus retain access to the notes area, but have to do without animations that have been created.
Optional "Markers" step: To make marks, click on the pencil icon in the title bar of the acquisition window.
Select one of the displayed color points and make the desired marks in the image section.
You can now make as many marks as you like in your recording window.
To remove existing markers in the recording window, click the pencil icon again.
Stop the "Screen share" function by clicking the Stop icon in the title bar.
The recording is stopped. (The stop can be recognized visually by the fact that the window frame turns blue again and the text "Screen share" is displayed in the title bar).
