MB to minutes for ProRes Proxy @ 45 Mbps Video
250 MB = about 0.74 minutes · fixed video-size estimate · ProRes Proxy @ 45 Mbps Video
Direct Answer
At ProRes Proxy @ 45 Mbps, 250 MB stores about 0.74 minutes of video
This result uses the fixed ProRes Proxy @ 45 Mbps Video bitrate profile to turn storage budget back into viewing time from 5.625 MB/s.
For 25 MB, the ProRes Proxy @ 45 Mbps Video bitrate estimate gives about 0.07 minutes of video duration.

SwitchExplanation
Formula: minutes = MB / (5.625 x 60) (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.
File size (MB): decimal megabytes of storage, where 1 MB = 1,000,000 bytes.
Duration (minutes): elapsed video time in minutes.
This route is useful when estimating how much video duration fits into a storage budget 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.
Common Conversion Values
| File size (MB) | Duration (minutes) |

Frequently Asked Questions
Which bitrate assumption is fixed on this page?
ProRes Proxy @ 45 Mbps with nominal video bitrate 45 Mbps.
How can I convert back from Duration to File size?
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.
