MB to seconds for ProRes LT @ 100 Mbps Video

Snapshot

At ProRes LT @ 100 Mbps, 250 MB stores about 20 seconds of video. Conversion Encyclopedia uses the same fixed conversion basis across the calculator, common values, and reverse page for this page.

Reference basis: This result uses the fixed ProRes LT @ 100 Mbps Video bitrate profile to turn storage budget back into viewing time from 12.5 MB/s.
Example: For 50 MB, the ProRes LT @ 100 Mbps Video bitrate estimate gives about 4 seconds of video duration.
Use the reverse page if you need the opposite direction with the same basis.

Full API documentation

Explanation

Formula: seconds = MB / 12.5 (bitrate 100 Mbps). Why: this page fixes the ProRes LT @ 100 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 ProRes LT @ 100 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.

Method & Bitrate Profile

Method basis: fixed bitrate estimate inverted to recover duration from storage size at 12.5 MB/s.
Profile reference: ProRes LT @ 100 Mbps Video (12.5 MB/s bitrate basis).
Consistency rule: snapshot, calculator, FAQ, and common-value rows all use the same fixed bitrate profile for this route.

Questions & answers

Frequently Asked Questions

Which bitrate assumption is fixed for this video profile?

ProRes LT @ 100 Mbps with nominal video bitrate 100 Mbps.

What is the opposite direction for 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.
