Estimate combined audio and video storage, or estimate the video bitrate available for a target file size. Use average bitrates and explicit container overhead assumptions.
How to use Video Bitrate & Storage Calculator
- Choose Estimate file size or Target file size.
- Enter the duration, audio bitrate and the other requested values.
- Read the estimate and review the overhead assumption.
A useful example
A 60-minute video at 12 Mbps with 192 Kbps audio contains about 5.4864 GB before container overhead.
Limits and assumptions
This calculator does not transcode media. Variable bitrate, encoder behavior, metadata and container overhead can change the final size. A target-size result is a planning estimate.
Frequently asked questions
Does this compress my video?
No. It calculates a size or bitrate estimate and does not read or modify a video file.
What should I use for audio bitrate?
Use the average audio bitrate expected in the output. Use zero if the video has no audio stream.
