Seconds to MB for 1440p 60fps @ 20 Mbps Video
45 seconds = about 112.5 MB · fixed video-size estimate · 1440p 60fps @ 20 Mbps Video
Direct Answer
At 1440p 60fps @ 20 Mbps, 45 seconds of video needs about 112.5 MB
This result uses the fixed 1440p 60fps @ 20 Mbps Video bitrate profile, anchored to 2.5 MB/s.
For 5 seconds, the 1440p 60fps @ 20 Mbps Video bitrate estimate needs about 12.5 MB.

SwitchExplanation
Formula: MB = seconds x 2.5 (bitrate 20 Mbps). Why: this page fixes the 1440p 60fps @ 20 Mbps Video video bitrate profile so duration-to-size calculations stay tied to one explicit bitrate assumption.
Duration (seconds): elapsed video time in seconds.
File size (MB): decimal megabytes of storage, where 1 MB = 1,000,000 bytes.
This route is useful when estimating how much storage a video export or stream will need under the fixed 1440p 60fps @ 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.

Frequently Asked Questions
Which bitrate assumption is fixed on this page?
1440p 60fps @ 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.
