Video Bitrate
Determine the average bitrate of a video file using its size and length—ideal for checking streaming requirements, upload constraints, or transcode targets.
Estimates average bitrate only. Confirm platform-specific encoding ladders and consider variable bitrate peaks when mastering content.
Examples
- 2.5 GB export (2,560 MB) over 180 s ⇒ 113.78 Mbps master file
- 750 MB tutorial over 420 s ⇒ 14.29 Mbps suitable for HD streaming
- 120 MB social clip over 45 s ⇒ 21.33 Mbps short-form delivery
FAQ
Why multiply by 8?
File sizes are typically in bytes. Multiplying by 8 converts megabytes to megabits, the standard unit for bitrate.
Does the output include audio?
Yes. The calculation uses total file size, so it covers video, audio, subtitles, and container overhead.
How do I convert to Kbps or Gbps?
Multiply the result by 1,000 for Kbps or divide by 1,000 for Gbps.
What if my platform uses decimal gigabytes?
Convert your file size to MB using 1 GB = 1,000 MB before entering, or switch to the binary value (1,024) depending on your storage convention.
Additional Information
- Bitrate (Mbps) = File size (MB) × 8 ÷ Duration (seconds).
- Target streaming platforms often recommend 8–16 Mbps for 1080p and 20–30 Mbps for 4K—compare your result to ensure compliance.
- Subtract audio bitrate manually if you need the pure video stream bitrate.
