Video Bitrate Calculator
Estimate the video bitrate that can fit inside a target file size after reserving room for audio and a safety margin.
Suggested video bitrate1509 kbpsIncludes a 5% safety margin plus room for audio/container overhead.
Why bitrate controls the target
For a fixed duration, a smaller file requires fewer bits per second. FitMyVideo uses the same basic relationship when it estimates a starting bitrate for exact-size compression.
When the bitrate becomes too low
A tiny bitrate at 1080p or 4K can look worse than a lower-resolution image encoded with enough data per pixel. That is why the compressor can recommend 720p, 480p or 360p for aggressive targets.
