Minutes to GB for 4K 30fps @ 20 Mbps Video
60 minutes = about 9 GB · fixed video-size estimate · 4K 30fps @ 20 Mbps Video
Direct Answer
At 4K 30fps @ 20 Mbps, 60 minutes of video needs about 9 GB
This result uses the fixed 4K 30fps @ 20 Mbps Video bitrate profile, anchored to 2.5 MB/s.
For 15 minutes, the 4K 30fps @ 20 Mbps Video bitrate estimate needs about 2.25 GB.

SwitchExplanation
Formula: GB = (minutes x 60 x 2.5) / 1000 (bitrate 20 Mbps). Why: this page fixes the 4K 30fps @ 20 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 4K 30fps @ 20 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.
Common Conversion Values

Frequently Asked Questions
Which bitrate assumption is fixed on this page?
4K 30fps @ 20 Mbps with nominal video bitrate 20 Mbps.
How can I convert back from File size to Duration?
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.
