How to use · Video bitrate calculator
  1. Enter the target size in MB and duration in seconds. The result is the total bitrate shared by video and audio.
  2. Run the calculation and check the result and its unit.
  3. Example: 500 MB × 8 ÷ 300 s ≈ 13.333 Mbps. Copy the result or compare a different target size.

The result estimates an upper budget for video plus audio. Subtract the audio bitrate before setting the video encoder, and leave room for container overhead. 128 kbps = 0.128 Mbps. 1 MB = 1,000,000 bytes. Actual output size is not guaranteed.
