How Does Zoom Reduce Video Quality?

Zoom has become a staple in our daily lives, especially in the wake of the pandemic. It’s a popular video conferencing platform that allows users to connect with people from all over the world through video calls.

However, one of the biggest issues with Zoom is its video quality. In this article, we will discuss how Zoom reduces video quality and what you can do to improve it.

What Causes Zoom Video Quality Reduction?

When you use Zoom for video conferencing, the app automatically reduces the video quality to ensure that everyone can participate in the call without any disruptions. This is done by compressing the data being transmitted over the internet.

Bandwidth Limitations

The main reason why Zoom reduces video quality is due to bandwidth limitations. When you’re on a Zoom call, your computer or mobile device is constantly sending and receiving data over the internet. The more people there are on the call and the more data being transmitted, the lower your overall bandwidth becomes.

Internet Connection Speed

Another factor that affects Zoom’s video quality is your internet connection speed. If your internet connection speed is slow or unstable, it can cause delays and interruptions during a call. This can result in poor audio and video quality.

How Does Zoom Reduce Video Quality?

To reduce bandwidth usage during a call, Zoom uses several techniques to compress and optimize data transmission:

Video Compression

One of the ways that Zoom reduces video quality is by compressing videos using codecs such as H.264 or VP8. These codecs are designed to reduce file size while maintaining acceptable image quality.

Frame Rate Reduction

Zoom also reduces frame rates during a call to save bandwidth. By default, Zoom uses 30 frames per second (fps) for desktops and 24 fps for mobile devices. However, you can adjust this setting in the app’s video settings to improve video quality.

Resolution Reduction

In addition to frame rate reduction, Zoom also reduces the resolution of the video being transmitted. By default, Zoom uses a resolution of 640×360 pixels for desktops and 360×240 pixels for mobile devices. However, you can also adjust this setting in the app’s video settings to improve video quality.

How Can You Improve Zoom Video Quality?

While it’s true that Zoom automatically reduces video quality to save bandwidth, there are several things you can do to improve your experience:

Upgrade Your Internet Connection

Upgrading your internet connection speed is one of the best ways to improve your Zoom experience. A faster internet connection will help ensure that your call isn’t interrupted and that you get better audio and video quality.

Close Unnecessary Applications

Closing unnecessary applications on your computer or mobile device can also help improve your Zoom experience. Running multiple applications at once can slow down your device and reduce its performance.

Use A Wired Connection

If possible, use a wired internet connection instead of Wi-Fi. Wi-Fi connections are often slower and less stable than wired connections, which can result in poor audio and video quality during a call.

Conclusion

Zoom is an excellent platform for connecting with people from all over the world through video calls. However, its automatic reduction of video quality can sometimes lead to frustrating experiences. By understanding how Zoom reduces video quality and taking steps to optimize your internet connection and device performance, you can ensure that your Zoom calls are smooth and enjoyable.
