Hours to GB for H.265 stream @ 4 Mbps Video
6 hours = about 10.8 GB · fixed video-size estimate · H.265 stream @ 4 Mbps Video
Direct Answer
At H.265 stream @ 4 Mbps, 6 hours of video needs about 10.8 GB
This result uses the fixed H.265 stream @ 4 Mbps Video bitrate profile, anchored to 0.5 MB/s.
For 1 hour, the H.265 stream @ 4 Mbps Video bitrate estimate needs about 1.8 GB.

SwitchExplanation
Formula: GB = (hours x 3600 x 0.5) / 1000 (bitrate 4 Mbps). Why: this page fixes the H.265 stream @ 4 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 H.265 stream @ 4 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?
H.265 stream @ 4 Mbps with nominal video bitrate 4 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.
