Full API documentation

Explanation

Formula: GB = (minutes x 60 x 5.625) / 1000 (bitrate 45 Mbps). Why: this page fixes the ProRes Proxy @ 45 Mbps Video video bitrate profile so duration-to-size calculations stay tied to one explicit bitrate assumption.

Duration (minutes): elapsed video time in minutes.

File size (GB): decimal gigabytes of storage, where 1 GB = 1,000,000,000 bytes.

This route is useful when estimating how much storage a video export or stream will need under the fixed ProRes Proxy @ 45 Mbps Video bitrate profile.

This conversion is profile-based rather than universal: encoded video size depends on bitrate and duration, so mirror pages should keep the same bitrate profile to remain comparable.

Method & Bitrate Profile

Method basis: fixed bitrate estimate scaled by duration at 5.625 MB/s for this route.
Profile reference: ProRes Proxy @ 45 Mbps Video (5.625 MB/s bitrate basis).
Consistency rule: snapshot, calculator, FAQ, and common-value rows all use the same fixed bitrate profile for this route.

Questions & answers

Frequently Asked Questions

Which bitrate assumption is fixed for this video profile?

ProRes Proxy @ 45 Mbps with nominal video bitrate 45 Mbps.

How do I reverse Duration to File size?

Use the mirror File size to Duration route; it applies the inverse relationship for the opposite direction with the same assumptions.

Can this be used for upload-time and storage planning?

Yes. It provides baseline estimates useful for archive sizing, CDN planning, and upload budget checks.
