Video Bitrate ↔ File Size Calculator
Convert between bitrate, duration and file size for any encoded video — plan a delivery that fits a size cap or a target bitrate.
A 50 Mbit/s mezzanine runs ~22.5 GB for a one-hour programme. Bitrate × time ÷ 8 is the single most useful media arithmetic — for fitting a Blu-ray, hitting an upload cap, or sizing storage. Note GB (10⁹, what drives quote) differs ~7% from GiB (2³⁰, what your OS shows).
