1. Calculate data usage and runtime

2. Understanding data usage

The payload data comes from the video and audio bitrate. A margin is added for transport, container, reconnects, and measurement deviation. With several bonded lines, the video stream doesn't come for free: bonding also distributes and protects data and can cause extra traffic.

Bitrate and data volume describe two different things. The bitrate says how much data is sent per second. The data volume shows the total amount used over the whole stream. A higher upload speed alone does not raise usage. What counts is the bitrate you actually set, the stream duration, and the extra protocol traffic.

The recording size shown refers to a local recording with the video and audio bitrate you entered. The estimated mobile data usage also includes the protocol headroom you chose. That's why the two results can differ.

3. A practical example for an IRL stream

At 6,000 kbit/s video, 160 kbit/s audio, and ten percent headroom, the math gives about 3.05 GB of data usage per hour. A four-hour stream needs roughly 12.2 GB. The local recording, without the assumed transmission headroom, comes to about 11.1 GB.

For a single stream day, don't cap your data plan at exactly this value. Extra usage can come from reconnects, a longer runtime, automatic uploads, and other apps on the streaming device. If you stream regularly, you can multiply the daily value by the number of planned outings and then add a personal safety margin.

4. Estimating runtime

Watt-hours are more useful for runtime calculations than a mAh figure alone, because devices and power banks can work at different voltages. The calculator compares the usable energy of the power bank to the power draw of your whole setup.

Heat, battery age, voltage conversion, cable losses, and short load spikes cut the real runtime. Screen brightness, active cellular modems, camera power, and charging at the same time also change consumption. So never plan down to the last calculated minute, and test the complete setup before a longer outing.

5. Planning data and power headroom

• Plan at least 10 to 20 percent data headroom for a normal outing.
• Calculate more generously with unstable connections, bonding, and frequent reconnects.
• Check background uploads, cloud backups, and automatic app updates before the stream.
• Don't run power banks down to the automatic shutoff all the time.
• Heat and charging at the same time can reduce the usable power.

The calculator gives you a traceable planning basis, but it doesn't replace a test under real conditions. For picture quality and a suitable video bitrate, the separate IRL bitrate and quality planner helps.
