Tips & tricks

Settings for the Best Perfomance

Optimal streaming preferences depend on the requirements of the platform you stream to, and on the equipment you have.

Higher resolution and higher frame rate ensure better live stream video quality. The bitrate should correspond to the selected resolution and FPS: the higher video quality requires a higher bitrate.

At the same time, streaming platforms limit streaming quality to reduce the load on their servers. Besides, increasing the resolution and frame rate increases your processor load, as well as high bitrate requires a lot of network resources.

Thus, optimal streaming preferences are always the balance between video quality and resource consumption. Here are factors that affect this:

Bitrate settings. As it was mentioned above, the bitrate should correspond to your resolution and fps. General bitrate recommendations can be found in this table. Besides, the Streamster bitrate recommendation feature is designed to help you set the right bitrate.

Streaming platform requirements. Streaming websites set limitations for broadcasters’ stream quality. If your stream preferences are higher, your video may be invisible on the platform or have issues. We recommend checking the platform’s requirements before you start your stream. 

Web camera specifications. Depending on your web camera, it can support a maximum of 720p, 1080p, 2K, or 4K resolution. It can also support a maximum of 30 or 60 FPS. We don’t recommend set up higher preferences than your web camera can handle because it will not improve your video quality.

Computer specifications. If your video quality is higher than your computer can process, Streamster will show you warnings: your CPU(1) and/or Encoder(2) indicators become yellow or red. Please reduce your Resolution and/or FPS, in this case, to make indicators green.

Internet upload speed. The bitrate you set is the data amount that is sent to the internet per second. So if your upload speed is, for example, 2 Mb/s, we don’t recommend setting more than 1000 kbps bitrate. In case if your internet connection is unable to proceed with the bitrate you set, your Streamster bitrate indicator becomes yellow or red (while other indicators are green). In this case, please reduce your bitrate and Resolution/FPS.

Your Streamster tariff plan. Streamster doesn’t have any limitations for Resolution and FPS in each pricing plan, but has the following bitrate limitations:
Free  – 4000 Kbps;
Lite – 7000 Kbps;
Regular – 10000 Kbps;
Professional  – 15000 kbps;
Premium – 25000 Kbps.
Higher bitrate limits are possible with individual pricing plans, please contact our support team for more information.

Bitrate is Lower than Expected or Unstable

There are at least 3 possible reasons why your bitrate may be unstable and 3 different solutions for this issue. Streamster indicators will help you to understand what causes the problem in your case.

Case 1. Processor/Encoder overloaded. CPU load indicator (1) and/or Encoder indicator (2) are red.

Solution 1. Close unnecessary applications or decrease video quality.  Use your Windows task manager to understand what applications have high CPU capacity and close them if it is possible. Reduce video resolution of FPS using Streamster main settings or encoder video quality using additional settings. Read more about encoder overload.

Case 2. Network problems (bad internet connection). The First 3 indicators are green, but the Bitrate indicator is yellow or red.

Solution 2. Use a cable internet connection instead of wireless, or switch the Streamster server. If the issue still persists, contact your internet provider. 

Case 3. Streaming platform’s issue. All 4 Streamster indicators are green, but the website bitrate is lower than expected.

If the issue is not resolved, please submit a support ticket.

Encoder Overload

Encoder overload affects your stream quality. Please keep attention to stream health indicators. If the “gear” indicator is red, the encoder is overloaded at the moment.

Case 1. One of the video or audio sources is unavailable. It may happen if you plug out the web camera that was used in your scene, or if another app uses it. In this case, the layer or audio device is highlighted light-red. 

Solution 1. For video devices/layers: ensure the device is available for the app or the data comes from a different source (web page, window, etc.). Or simply remove this layer. For audio devices: make sure that the device is connected, choose a different device, or mute the audio.

Case 2. The quality you set for the video is too high for your CPU.

Solution 2. Try to reduce your processor load with the methods, described in this article.

If the issue is not resolved, please submit a support ticket.

How to Reduce Your CPU Load

If, according to stream health indicators, your encoder is overloaded and/or your CPU load is close to 100%, you need to decrease your recourse usage to avoid issues with your live stream. 

1. Close unnecessary applications

Live streaming requires a lot of computer resources. Thus, please open your Windows Task Manager to check what other applications are using your CPU recourses and close unnecessary ones. 

2. Make sure that the encoder is set to Hardware/Auto.

Go to the app settings. In the “Encoding” section, find the “Encoder type” setting and switch it to “Auto” or “Hardware“.

3. Switch your "Performance vs. Quality" setting to "Speed".

Go to the app settings. In the “Encoding” section, find the “Performance vs. Quality” setting and switch it to “Speed“.

4. Fit your video to the full scene size.

Open the layer setting (e.g. your web camera). Click the “Maximize” button to fit your video source feed to your broadcasting scene. 

5. Remove unnecessary layers.

Click on the video preview, check the list of layers that are visible on your video, and delete unnecessary ones. 

6. Decrease your Resolution and/or FPS.

Click on the video preview. Select a lower value for your video resolution and/or FPS. 

Stream to Platform Error

The channel is highlighted red and the stream doesn’t start.
