Run a network test
Make sure you have a good network before you go live
Before you go live, it's important to check the speed and quality of your network connection. A poor network connection can lead to a low-quality stream. Here's how to run a network test to make sure your streaming settings are optimal before you go live.
- From the Bambuser mobile app, select the show you’re going to host from either Scheduled or Upcoming shows.
- On the next screen you’ll have three options:
- Run network test
- Get ready
- Tap on Run network test.
Optimal streaming conditions
Sustained and stable upload speed is the most important factor when broadcasting live video. The Bambuser app automatically adapts to your available network bandwidth by adjusting video quality, but sudden changes in connection speed may manifest as a low frame rate for a moment. If the network drops out entirely, the app will try to reconnect automatically.
A video’s bitrate is the rate at which data is transferred from one point to another. In video streaming, bitrate concerns how much data each second of video consumes.
The higher your video quality, the higher your bitrate. A frame of high-quality video contains more data than a frame of low-quality video, and so it can take longer to transfer that data from point A to point B.
Resolution is the number of pixels in the video frame. The higher the resolution, the more pixels in the image. For example, 720p video resolution means an image with 720 pixels horizontally and 1280 pixels vertically.
Regardless of resolution, your video will be scaled to fit the size of the player. If your video is transmitting at 360p, for example, the image will be slightly blurry compared to 720p.
Before going live, test your connections (Wi-Fi and 5G/4G). You can visit fast.com from your device to get a quick estimation of available bandwidth, especially upload speed.
High upload speed is a good indicator of a strong network — even if it doesn't always guarantee long-term stability.
The highest 720p video resolution uses, at most, 7 Mbps in terms of upload speed.
Good quality 540p video resolution can be attained at around 2 Mbps. As long as the connection is relatively stable, viewers generally don't react negatively to this.
Below 2 Mbps may still be tolerable for some use cases, but may not meet the expectations of viewers on a professional production.
Networks with bandwidth below 1 Mbps, or Wi-Fis with many users that compete for bandwidth, are generally not suitable for professional productions.
The highest 720p video quality will consume 2-3 GB of data per hour, depending slightly on the capabilities of different devices.
A stable, non-crowded network will provide a better experience than a crowded but theoretically “fast” network. Try to avoid Wi-Fi networks that are shared with an unknown number of people, as sudden bursts in traffic by other users can severely affect your upload speed.
