How to improve video quality in conferences. Theory and practice

The quality of the video often depends on the effectiveness of the negotiations or communication. There are many factors that can affect image transmission. In this article, we will analyze the main issues and share ways to solve the most popular problems related to the quality of the video stream.

Equipment

The camera responds by stealing the video. It can be a built-in camera in a laptop or phone, a connected WEB or PTZ camera. They differ in quality and purpose. The weakest, as a rule, are cameras built into the device, since manufacturers often save on quality and supply the cheapest modules in the kit.

WEB cameras are the most popular devices on the market with thousands of models: from budget devices to the business segment with premium quality. PTZ cameras are used to equip various types of meeting rooms, lecture halls, conference rooms and have a high-quality sensor and the ability to remotely control.

Let’s take a look at what can get in the way of a video call and which camera provides the best video quality.?

What are the problems of video quality from the camera??

“Weak” camera

As mentioned above, built-in cameras, like budget WEB-cameras, do not allow us to Get a good quality image. When the resulting image is expanded to full screen, all its flaws become clearly visible.

Let’s compare the image from the built-in camera of an ASUS laptop and a Logitech c920 webcam:

In the same way, you can compare budget WEB-cameras with another segment. Just Display your image on the screen and try to look at the quality in different scenes.

Weak computer

The processor is responsible for processing and transmitting the image. If he does not have enough computing power and he noticeably “freezes” during video calls. then the problem is in him.

The signal can be a high level of processor load during a call (can be viewed in the task manager), system freezes as a whole, significant heating of the laptop.

The processor load can be viewed in the task manager

Try to close applications running in the background, extra tabs in the browser, or clean the system the second way, up to reinstalling the OS.

Also, the problem may be in the camcorder driver. Try installing or updating it. You can always download the driver from the manufacturer’s website.

If that doesn’t help. time to change the processor, RAM and the second computer hardware.

Weak communication channel

With a weak Internet connection, the video can be significantly distorted, partially displayed and disappear for seconds. This may be due to a weak connection channel. Check your speed on the website: http://www.Speedtest.Net/ Recommended connection speed for good quality video calls. 500 kbps. 1.5 Mbps on incoming and outgoing channel. If your connection DOES NOT provide this speed, but the provider’s tariff is higher, check: Internet cable, WI-FI router and programs that can download the channel on your computer.

Why does the image get noisy?

Image noise. this is an attempt to compensate for the lack of light in dark areas with the camera and weak matrices will produce a poor-quality picture.

The difference between clean and noisy images

This is most often caused by low light on the subject. Try increasing the brightness or number of lamps, or increasing the lighting from a natural source. open the curtains! Some cameras may produce a “noisy” image after extended periods of use. This is due to an increase in the operating temperature of the chamber. You can try to give her time to cool down and repeat the video call. Many modern cameras are equipped with a high-quality sensor, which copes with the delight of the image even in low light and does not make noise. We draw your attention to PTZ cameras.

What is the maximum angle of view and rotation needed for conferences?

If you are placing the camera in meeting rooms, then you need everyone to fit into the frame, the camera’s angle of view is responsible for this, with its increase, the camera’s field of view also increases.

Try to choose a camera with a viewing angle of at least 75 degrees, then most of your room will accurately fit into the frame, but do not forget that with increasing angle, objects, especially distant ones, will become poorly visible. In this case, PTZ cameras with the ability to zoom (zoom) come to the rescue. With them you will be able to show the general plan, and significantly bring the speaker on the screen closer, which gives an additional effect of presence.

But not all PTZ cameras have a wide maximum viewing angle, but the undoubted advantage lies in the ability to control the rotation of the lens using the remote control, through a computer via RS232 protocols | 485, or via a driver using the UVC protocol. For example, the CleverMic Wide PTZ camera has a viewing angle of 105 °, can rotate 340 ° on the horizontal axis and 120 ° on the vertical axis. Other PTZ cameras can be viewed in the corresponding section on our website.

Why is the image dark or only the silhouette of the speaker is visible??

The silhouette may appear in strong light behind the subject. In this case, we advise you to choose the right place so that the light illuminates the face, and does not drown out your image with its brightness. Conversely, if the image is generally dark, it is recommended to increase the light level. Move closer to a window or install more powerful lamps. Note that modern cameras are more effective in dealing with both problems and are able to produce high-quality images even in poor conditions. Maybe it’s time to update?

Small objects, the interlocutor cannot see the faces

Videoconferencing often involves many people from both sides, different speakers, presentations, and more. A static camera can capture a general shot, but it will not be able to focus the attention of the interlocutors on a specific speaker. In this situation, we recommend using PTZ cameras. They are equipped with optical zoom, can be conveniently installed above the monitor or on the ceiling, are remote controlled and some are equipped with a speaker tracking function. Your interlocutors will appreciate it. You can watch the work of the PTZ camera CleverMic 1020z in our video.

Image has streaks or flickering

This effect is called flickering and is caused by the desynchronization of the refresh rate of the artificial lighting and the WEB-camera.

You can deal with this programmatically. We’re looking for refresh rate settings. For video communication, I use TrueConf Online and I found the following column in the webcam settings:

Choosing 50 Hz completely solved the problem. I also found a similar setting in the driver settings of my webcam:

Poor video quality when making a video call from a mobile phone

This may be due to one of the following reasons:

• Poor connection quality or wireless wi-fi. The solution will be to find a place with the best mobile network signal or deal with the state of wi-fi.
• Bad software. Many applications are NOT optimized and cannot provide quality communication. We recommend trying TrueConf Mobile.
• The loaded RAM of the phone. We recommend that you close all unnecessary applications in the background and try to conduct the session again.
• Poor phone camera quality. You can only solve this problem by buying a new device.

The video of the interlocutor freezes

If more obvious problems besides this one are NOT noticed and the computer generally works fine, then there can be two reasons:

• Bad communication channel
• Problems on the side of the interlocutor

Picture and sound out of sync

We recommend that you update your device driver or use other software. Try TrueConf Online.
