Enter your video settings to estimate the resulting file size in MB and GB.
Before exporting or uploading a video, it helps to know roughly how large the final file will be. This calculator estimates file size from bitrate and duration — the two factors that matter most for final size, since resolution and frame rate mainly influence what bitrate you should choose.
Step 1 — Choose your resolution and frame rate as a reference for picking a sensible bitrate.
Step 2 — Enter your bitrate in Mbps (check your export settings or use the Bitrate Calculator).
Step 3 — Enter the duration in minutes and calculate.
Confusing Mbps with MB. Bitrate is measured in megabits per second (Mbps), while file size is in megabytes (MB) — there are 8 bits in a byte, so this matters for accurate estimates.
Ignoring audio bitrate. This calculator estimates video bitrate only; add roughly 5-15 MB per hour for typical audio tracks.
A common range is 8-12 Mbps for 1080p at 30fps, and higher (12-20 Mbps) for 60fps or fast motion.
No, this estimates video bitrate only. Add a small amount for the audio track separately.
