Bitrate Calculator — Required Bitrate
Calculate the bitrate needed for target quality and file size.
How We Calculate This
Bitrate Formula
Bitrate (Mbps) = file size (MB) x 8 / duration (seconds)
This gives the average bitrate. Variable bitrate (VBR) encoding will fluctuate around this average based on scene complexity.
