Video bitrate calculator
Estimate the combined average video and audio bitrate in Mbps for a target file size in MB and duration in seconds
Link to this calculationHow to use · Video bitrate calculator
- Enter the target size in MB and duration in seconds. The result is the total bitrate shared by video and audio.
- Run the calculation and check the result and its unit.
- 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.
