MB to seconds for H.265 stream @ 4 Mbps Video
10 MB = about 20 seconds · fixed video-size estimate · H.265 stream @ 4 Mbps Video
Direct Answer
At H.265 stream @ 4 Mbps, 10 MB stores about 20 seconds of video
This result uses the fixed H.265 stream @ 4 Mbps Video bitrate profile to turn storage budget back into viewing time from 0.5 MB/s.
For 1 MB, the H.265 stream @ 4 Mbps Video bitrate estimate gives about 2 seconds of video duration.

SwitchExplanation
Formula: seconds = MB / 0.5 (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.
File size (MB): decimal megabytes of storage, where 1 MB = 1,000,000 bytes.
Duration (seconds): elapsed video time in seconds.
This route is useful when estimating how much video duration fits into a storage budget 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 File size to Duration?
Use the mirror Duration to File size 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.
