How To Improve Video Streaming Quality

Video quality issues. Buffering, lag, low resolution. We’ve all experienced these problems. For professionals and businesses, bad quality videos have a negative impact on your brand. Therefore, this blog will look at how to improve video streaming quality.

Specifically, we’re going to look at what you can do as a broadcaster to improve the quality of your steaming video.

In general, streaming quality seems to be increasing, with video start failures down 33 percent year-over-year, buffering down 41 percent, and picture quality up 25 percent. Let’s keep these trends moving in the right direction with the following tips.

Maximizing Quality Up Front

How To Improve Video Streaming Quality

Before describing how to improve quality, we need to define two different types of quality issues. There are those you can control, and those you can’t.

As a broadcaster, you can control the initial quality: quality in. However, you don’t have much control over the viewer. They may simply have a slow internet connection or an outdated device. There isn’t much you can do to help them.

Viewers don’t like to watch poor quality video. Bad quality reflects poorly on your business. Luckily, good quality in will mitigate some of the issues on the other end.

Camera

Cell phone cameras usually provide a poor quality video. And older cameras may have low resolution and poor image processing. This can’t be redeemed. As the saying goes, garbage in, garbage out. That’s especially true in low light. If your original recording is poor quality, there is nothing you can do to fix it.

Therefore, using a good quality camera will provide the best possible image at the very beginning of your broadcast.There’s no excuse for not using a full HD or 4K camera in 2019 and beyond.

Encoder Settings

Most live streams are transmitted from an “encoder.” An encoder is a software or hardware tool that transcodes your video into streaming compatible formats. This is then sent to your online video platform.

Here are our recommended encoder settings.

  • Video Codec: H.264 (Main or High Profile)
  • Audio Codec: AAC
  • Variable Bitrate: On
  • Frames Per Second: 30 is standard
  • Keyframe Interval: 2 seconds

There are other important encoder settings like video resolution, video bitrate, and audio bitrate. For recommendations on these values, read our full guide to encoder settings.

Upload Speed

How To Improve Video Streaming Quality For Your Viewers

When you broadcast streaming video, you need sufficient internet speed to sustain the streaming. For live video, your upload bandwidth should be at least twice your broadcast bitrate.

To determine your broadcast bitrate, add your video bitrate to your audio bitrate. If you are broadcasting in multi-bitrates, add all of them together.

Here are a few more recommendations for getting the most out of your connection:

  • If possible, use a wired Ethernet connection. WiFi can be unstable
  • If you must use WiFi, move close to the router to ensure a clear signal.
  • Close unnecessary web browsers and applications to free up bandwidth.
  • Remove other devices from the network. Every additional device on a network draws more bandwidth.
  • If necessary, purchase a faster internet plan. Remember, for broadcasters the upload speed may be more important than download speed.

Selecting the Right Online Video Platform

The next method to maximize video streaming quality is to select the right online video platform. An OVP provides streaming solutions for managing and hosting content. They may also provide other tools for monetization, security, and so on.

There are three ways that OVPs can directly influence quality.

  1. First is content delivery. Look for an OVP that uses a large, well-respected CDN like Akamai. A network like this will ensure content is distributed rapidly. Also, it will scale to a large audience smoothly.
  2. Second is quality limits. Look for an OVP that allows you to broadcast in 1080p full HD. In general, 4K broadcasting isn’t ready for the mainstream.
  3. In the next section, we’ll look at the third way your OVP influences video streaming quality.

Transcoding and Multi-Bitrate Streaming

Another way that your OVP can influence video streaming quality is through transcoding and multi-bitrate streaming.

Modern video players are adaptive. This means that they automatically detect the viewer’s internet speed and adjust accordingly. For a viewer on a slow connection, they’ll deliver a lower quality video. For those on a fast connection, video quality will be higher.

This is dependent on your OVP offering transcoding and multi-bitrate streaming. Multi-bitrate streaming refers to the process of sending a live stream out in multiple different qualities at once. Transcoding does a similar thing, but for VOD. Plus, transcoding happens in the cloud.

If you want to improve video streaming quality, make sure your OVP supports these features.

Test Thoroughly

This isn’t a technical recommendation. However, skipping testing is a bad idea. Streaming video has a lot of moving parts. We recommend you engage in thorough testing before launching your content. This could look like:

  • Test video embed on your website. Does everything look correct?
  • If using multi-bitrate streaming, test video quality at different bitrate levels. Are different levels available and viewable?
  • Test videos on both slow and fast internet connections. If buffering minimal?
  • Conduct a test transitioning from fast to slow internet. Does the video player adapt?
  • Do some stress testing for encoders, cameras, and other equipment. Will equipment fail under load?
  • Test your total workflow. Make a test live stream and broadcast privately. Does everything work properly?

24/7 Customer Support

How To Improve Video Streaming Quality

We’ll finish off with another non-technical solution. Customer support is critical for video streaming quality. When a problem arises, you can’t afford to be stuck waiting.

Many video platforms offer limited tech support—or even none at all. In contrast, professionals need a platform that includes 24/7 tech support.

That’s because streaming happens at all times. The evening is peak time for video. Ideally, your tech support should also be available via phone, chat, and email. You don’t want to be stuck chatting with a bot or submitting a ticket while your video streaming quality suffers.

Conclusion

These are only a few of the suggested methods for dealing with the most common video streaming quality problems. As a broadcaster, you need to know how to maximize the quality of your broadcasts. Any problem your viewers have is a problem you have. One survey showed that 62 percent of viewers are likely to view a brand more negatively if they publish a poor quality video.
