SwitchExplanation
Formula: GB = (hours x 3600 x 18.375) / 1000 (bitrate 147 Mbps). Why: this page fixes the ProRes 422 @ 147 Mbps Video video bitrate profile so duration-to-size calculations stay tied to one explicit bitrate assumption.
Duration (hours): elapsed video time in hours.
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 422 @ 147 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.

Frequently Asked Questions
Which bitrate assumption is fixed on this page?
ProRes 422 @ 147 Mbps with nominal video bitrate 147 Mbps.
What is the opposite direction for 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.
