The quality of your video call requires that several dependencies be met first! 

By: Leonidas Georgiou

Did you know that your meeting video quality is dependent on many factors?

One side of it is the hardware you’re using, from the webcam to the microphone. Lighting and specifically the brightness of the room, also makes a huge difference in your image quality. Remember, a webcam is not a $ 1000 DSLR camera.

On the other hand, the quality of your internet connection is also essential, if not more important, than the hardware aspect in some cases. An unstable internet connection will immediately invalidate the price tag of your video streaming setup.

Meeting Quality Profiles

As a host, 3CX VC (Video Conferencing) allows you to set 3 profiles for your meeting. From Low (800 kbps) to Balanced (1800 kbps) and Quality (3500 kbps) mode. Each profile defines how much each participant should send into the meeting.

Download

The chart below shows how each meeting user requires much download bandwidth. You’ll notice that the increase in bandwidth requirements isn’t linear across all profiles, e.g., you don’t need as much download bandwidth as you’d think if there are more and more users piling into a meeting. The reason behind how this works will become apparent in the following chart that shows upload bandwidth requirements and the correlation between download and upload bandwidth increases.

Upload 

The chart below shows how each meeting user requires much upload bandwidth. You’ll notice that the more users, the less upload bandwidth each user needs to have. You might think this is strange, but there’s some sound reasoning behind this. 

The more users with video connected, the more video panes you’ll see in 3CX. The more video panes, the smaller they’ll be so they can fit on your screen. The smaller they are, the less detail you’ll be able to discern in video quality. 

3CX takes advantage of this, and rather than continuing to use too much bandwidth for a tiny video pane, it decreases bandwidth slightly. The bigger your video pane, the more bandwidth you’ll use and vice versa.
