Hi Vijay:
Can you specify the video you are talking about? Is it the video in the virtual classroom or the video uploaded in content area [like this one here:
http://www.wiziq.com/tutorial/39563-Conception-Animation]. In the first case, when you share the video in the virtual classroom, choose show in the whiteboard option [just below where you select your device] in the video selection window. Now, use the + and - signs to control the display size. In the video in content area, just click on the icon next to where WiZiQ is written.
It is possible to link your live physical classes to virtual classroom. You will need a high quality camera as well as portable mic to capture your voice. In the virtual classroom, select the appropriate devices to broadcast your video and audio. We know of a couple of teachers who have tried this with great success.
Thanks
