What is Twitch?
Originally launched in 2011 as a platform to stream gaming content, Twitch is now an interactive live streaming platform for music and other creative content.
It is a highly popular platform among youth, with over 240 million unique visitors per month and 100 million downloads. The USA alone accounts for nearly 35 million viewers, which is still expected to continue growing exponentially in 2025.
The popularity of Twitch can be attributed to its features, like being an interactive platform, a wide reach that brings global audiences, and monetization methods like ads, subscriptions, and affiliate programs.
Being one of the most popular platforms among gamers, streaming speed and quality remain constant considerations among users. The next section covers the important aspect for your video streaming, namely, bitrate.
What is Bitrate in Streaming
Bitrate is the amount of data transmitted per second during streaming. Bitrate affects the quality of your video and ensures it is buffer-free.
It is measured in megabits per second (Mbps) or kilobits per second(kbps). To have excellent video streaming quality, your bitrate should be high. The ideal bitrate is often suggested by the streaming platforms.
Generally, the options are Constant Bitrate (CBR) and Variable Bitrate (VBR). CBR ensures a consistent data flow with a constant bitrate, whereas VBR adjusts the bitrate according to the complexity of the content in the same video.
Standard recommendations of bitrate for Twitch
Twitch suggests the bitrate required for streaming. It has fixed an upper limit of 6000 kbps, above which streaming may experience lag.
| Resolution | Frame Rate (FPS) | Recommended Bitrate |
|---|---|---|
| 1080p | 60 fps | 6000 kbps |
| 1080p | 30 fps | 4500 kbps |
| 720p | 60 fps | 4500 kbps |
| 720p | 30 fps | 3000 kbps |
| 480p | 30 fps | 1000–1500 kbps |
You should choose a bitrate that the platform can process based on its recommendations. If not, it will affect the streaming quality.
Video Bitrate vs. Bandwidth: Understanding the Difference
Video bitrate and bandwidth are often confused but play distinct roles in streaming quality. Bitrate refers to the amount of video data transferred per second during playback, directly impacting video clarity.
Bandwidth, on the other hand, is the maximum data transfer capacity of your internet connection. For smooth streaming, your available bandwidth must exceed the video's bitrate—otherwise, buffering and playback issues may occur.
Common Bitrate Problems and How to Fix Them
| Problem | Cause | Solution |
|---|---|---|
| Buffering During Playback | Bitrate too high for available bandwidth | Lower the video bitrate or upgrade internet speed |
| Poor Video Quality | Bitrate too low | Increase bitrate to match resolution and frame rate |
| Audio-Video Sync Issues | Inconsistent encoding or high bitrate fluctuations | Use consistent encoding settings and proper keyframe intervals |
| Frame Drops or Lag | Network instability or CPU overload | Optimize encoding settings and use hardware acceleration |
| Playback Freezes on Some Devices | Device compatibility issues with high bitrates | Offer multiple bitrate options (adaptive bitrate streaming) |
How to choose the best bitrate for streaming on Twitch?
Internet speed
The speed of your internet connection is the most important factor in choosing the right bitrate. The general thumb rule is to follow the 75% rule. This will allow a stable connection for your other activities that use the internet without any fluctuations.
For instance, your bitrate should not be more than 75% of the total upload speed. If you have an upload speed of 10,000 kbps, the maximum bitrate possible is 7500 kbps only, beyond which you may face disruptions in streaming.
You should run a speed test to determine the upload speed in real time for your platform.
Internet speed of the audience
Your audience’s internet speed is as important as yours. With very high bitrates, viewers may experience lag. This is because not all viewers have a high-speed connection. For those with slower net speed, videos will stream with a lot of buffering in between. This way audience will lose interest in watching a live stream. An optimized bitrate would be a good option for streaming on the Twitch platform.
Viewers who are Twitch partners have the option of choosing a lower resolution if their internet speed is not stable.
Type of content
The best bitrate to choose depends on the kind of content you want to stream. If it is fast-paced like gaming, you need a high bitrate. For slow-paced streaming, a lower bitrate is sufficient as the chances of pixelation are low.
Tips to improve bitrate for streaming on Twitch
1. Internet connection
The first thing is to improve your internet connection as a high-speed internet connection can only handle higher bitrates, and deliver seamless streaming.
Check the upload speed with the help of a speed test online. Ensure that the upload speed is almost 2 times your bitrate so as to allow smooth upload without any breaks.
Sometimes, where wifi isn’t stable, you could try using an Ethernet connection to improve speed. Wired connections are more consistent and are well-suited for live streams.
2. Streaming software
You should adjust your bitrate to find the optimum limits for seamless streaming. This is based on your internet speed and hardware.
Hardware encoders help achieve quality streaming even at higher bitrates and is generally preferred over software encoders, that place more strain on the CPU.
3. Quality equipment
Professional-quality equipment can also help improve bitrate. For example, a good microphone ensures good audio quality, essential for high audio bitrate.
4. Adjust your bitrate
Watch if the bitrate is just fine for your system or is causing a strain during the stream. If it causes pressure, you can understand that there will be lag in streaming, so adjust the bitrate to only that much the system can handle.
5. Twitch inspector
This is a free tool provided by Twitch where streamers can diagnose the quality if their stream including bitrate, drop in frames, etc.
The tool provides a bitrate graph from which you can check the minimum and maximum bitrates. By identifying stable bitrates, you can adjust your streaming accordingly before it is live.
Steps to test streaming bitrate on Twitch
- First, set your streaming setup right. See if all equipment is connected and good to go.
- Select the bitrate for streaming recommended for Twitch.
- Initially run a test stream with the Twitch inspector to find out how the streaming would be.
- Check if the bitrate is just right, which is indicated in the graph. You will find the ideal bitrate for streaming.
- Adjust your bitrate if it falls short of the ideal one for streaming.
- Test repeatedly to set up your ideal bitrate before actually going live.
- Once you are sure of all the above steps, you can start your live streaming.
Conclusion
Live streaming on Twitch is very popular, with over 35 million daily active users. If you are looking to leverage this for streaming your content, one of the important aspects you should consider is bitrate. With allthe advanced equipment and great quality content, if the bitrate is not correct, you may fail to attract your target audience.
