Lagging, buffering, and lagging streams will repel viewers faster than anything else. You may already be aware of this issue if you’ve seen your live chat responding a few seconds earlier than you have on your live stream. The bright side of this issue is that you do not have to build up all your system from scratch to decrease latency of your stream – most of what needs to be done can be done at the infrastructure level, not at the platform selection stage. This blog will discuss how to reduce streaming latency using your infrastructure without changing your streaming platform.

Why Latency Happens in the First Place

If you want to reduce streaming latency, you should first learn what causes this problem. In order for video to be delivered to a user’s device, it must go through your encoder, ingest server, process and transcode, content delivery network, and finally reach the end user. All of these processes take some time, and when everything goes wrong, they add up to several seconds and even minutes.

Many people believe that the issue lies with the platform; however, many times, the problem comes from the route the data takes to get to the platform. The place where streaming server latency optimization truly makes a difference is in the actual transport of the data. The YouTube, Twitch, or custom player is simply the presentation layer, while the work is being done below.

Server Location Is a Bigger Deal Than You’d Think

One of the easiest but often ignored methods to reduce streaming latency is by choosing servers close to the location where your audience is located. There are certain delays when it comes to data transmission; speed of the internet connection is not an exception.

If your audience is concentrated on the East Coast, routing through a New York streaming server for low-latency US delivery cuts out a lot of unnecessary travel time compared to bouncing traffic across the country first. The same logic applies on the opposite coast — a Los Angeles streaming server for West Coast viewers keeps that leg of the journey short for anyone tuning in from California, Oregon, or Washington.

This isn’t just a US consideration either. Streamers with a Canadian audience often see noticeable improvement using a Montreal streaming server for low-latency Canadian delivery, especially compared to routing everything through US-based infrastructure by default. And for creators building an audience across the Atlantic, a London streaming server for low-latency European audiences can shave off a meaningful chunk of delay for viewers in the UK and nearby countries.

The pattern here is simple: the closer your server infrastructure sits to where your viewers actually are, the less distance your stream has to travel, and the easier it becomes to reduce streaming latency without changing anything about your platform or software.

Encoding Settings Matter More Than People Realize

Whereas server location deals with the time of transit, encoding settings have a direct impact on the amount of processing that must be done prior to sending the stream out of your system. Low-latency encoding profiles process videos more quickly, albeit with somewhat larger file size.

Intervals between keyframes also come into play. The smaller the interval is, the quicker the stream will be able to re-synchronize, which will help reduce streaming latency, especially when it comes to viewers tuning into the stream in the middle of it or having an unreliable connection. This setting is very minor and often overlooked by many streamers.

Protocol Choice Changes Everything

But not all streaming protocols are fast streaming protocols. The conventional HLS protocol, although reliable and compatible with many systems, usually adds a few seconds of latency, as the protocol requires buffering videos in segments prior to its transmission. If minimizing latency is your primary concern, then low latency video streaming protocols, such as LL-HLS or WebRTC, should be considered regardless of whether your platform uses them out of the box.

Protocol changes do not always involve platform changes. It is often possible to configure current systems such that a lower-latency protocol is added below the interface that users have come to expect. This is a change in technology rather than in branding – and this is the type of change required in order to reduce streaming latency without breaking the user’s viewing experience.

Live vs On-Demand: Different Priorities

Latency is also not a constant concept based on the type of data being transmitted. In the case of a Live Streaming VOD platform, the importance of latency differs in each format. Live content requires immediate transmission, particularly in cases where interaction is expected and the viewer depends on timely responses. In the case of VOD data, there is no time constraint given that users have no expectations for a timely connection.

Grasping the difference is essential when it comes to knowing how to prioritize the areas in need of optimization. For example, if the majority of your latency issues occur during live sessions, then it is exactly those sessions where your efforts to select a proper server and protocol can make the biggest impact – not by optimizing VOD.

Testing Before You Commit

All efforts made towards reducing latency need to be tried out in a real-life setting rather than simply assuming that everything will work based on the specifications. Stream to a test environment and measure the actual latency from your source to the viewer’s screen before making any changes, such as changing the location of the server, encoding, or the protocol used.

It is important because latency problems are never usually the fault of any one factor. A streamer could change servers, notice a difference, and think the problem was resolved only to find out months later that the encoding had been adding latency all along. Testing is more tedious than trial-and-error, but it is the only method of reduce streaming latency that actually works.

Conclusion

There is no need to completely switch platforms if you need to make your streaming less delayed since most of the delays will be caused by server location, video encoding techniques, or protocols used, and each of them can be changed without altering anything visible to viewers. Be it rerouting video through servers that are closer to your viewers or using some other protocol under the hood of the software you use, there are ways to reduce streaming latency that won’t require you to start from scratch.
