Bitrate in Streaming

Bitrate in Streaming

Data transfer strongly influences the resulting quality of video and the size of its data.

This is why it’s a good idea to decide what video you’ll be publishing and where you want to place it. It’s also necessary to take the scene in the video into consideration. If you only have one moving object in the shot – a moderator, for example, in front of a static background – you can get away with lowering the bitrate to as low as several hundred kb/s. The image will lose some quality, but it will still run smoothly and stay “watchable”. But, if the background of the scene is moving (the waves of the sea, trees waving in the wind, rain, or snow), the resulting video will become choppy when running at such a low bitrate. This is because the scene at the given moment is creating such a large amount of data that it’s too much for the data transfer settings to handle. This is when it’s better to turn up bitrate to speeds higher than 10Mb/s, considerably improving quality.

However, you’ll have to consider the fact that the resulting size of the video’s data will have grown dramatically. You might even find that it’s unusable for your intended purposes. That’s why you have to weigh up all the aspects: selecting a suitable shot, resolution, and resulting quality, all while staying within the capacity of the link you’re using.

The role of data transfer in streaming live video

Data transfer is the most important criterion for a smooth live stream. You’ll have to choose the speed of your internet connection depending on what bitrate you’ll be streaming at. Your primary interest will be upload speed. Everyone would love to broadcast live streams in the highest possible resolution – Full HD or now even 4K – but they often fail to realize that data transfer is highly dependent on the specifications of their internet connection. With Full HD resolution, you can reach values of 6Mb/s and, with 4K, values of even 15Mb/s. Those are considerable requirements for upload lines. That’s why you should always check if your connection has the proper capacity for what you’re planning to stream. If you realize it doesn’t, you should consider lowering the resolution of the streamed video to, e.g. 720p at a transfer speed of 4Mb/s, ensuring you a smooth live stream.
