Estimate Video Recording Storage
Plan storage from recording bitrate and recording duration.
Practical Example
A 100 Mbps recording for one hour uses roughly 45 GB before overhead.
Factors That Affect the Result
Bitrate, duration, number of cameras, audio streams, codec mode and container overhead affect actual storage.
Frequently Asked Questions
Does VBR change size?
Yes.
Should I plan extra capacity?
Yes.
Does resolution alone determine size?
No.

Recording Storage Planning
Recording storage estimates are driven mainly by bitrate and total recording time. Use the expected production bitrate rather than a platform playback bitrate when possible. Leave additional free space for audio tracks, proxies, thumbnails and temporary files, especially for long sessions or high-resolution footage.
Methodology and Practical Limits
Recording storage is primarily driven by total bitrate × duration. Resolution alone does not determine file size; codec efficiency, frame rate, bit depth, chroma sampling, audio bitrate and variable-rate behavior can all change storage needs.
