Video clarity in video conferencing could be great when you are video chatting with a friend close to the screen. Most programs also boast clarity during video conferencing session when you have a multipoint session on laptops or desktops.
However, in a group setting it may be a challenge to see necessary documents.
Usually most video conferencing sessions are in a group setting.
In group settings the screen is usually placed at a distance where it is viewable by the whole room.
This is where it gets challenging.
The further the screen from the audience, the bigger the screen you may have to have the conferencing on so everyone can see. But the bigger the screen, the more pixels are required for an extra clear picture.
For example, if the pixels on your screen are 640 by 480 it would look clear on a 32 inch screen. If you have a larger crowd to present to, that same 640 by 480 pixels on a 60 to 70 inch screen would look blurry.
For a screen that size, 1024 by 600 or 1080 would be ideal for a clear picture. Another concern is the codec (compressor / de-compressor). This has to do with how video conferencing works and how fast video is transferred from the giver to the receiver. This affects frame rate.
In an average or poor video conferencing system you will get poor frame rate (according to professional standards). As a result, this will cause the video to freeze many times or be choppy during your conference. This could be a major drawback to your meeting.
This is why more professional businesses go with telepresence with the highest video clarity in video conferencing experience to ensure that this doesn't happen.
