1 Duration (seconds) =
2.5 File size (MB)

Explanation

4K 30fps @ 20 Mbps uses 20 Mbps (2.5 MB/s). MB = seconds x 2.5. With input 1 s, result is 2.5 MB.

Duration to File size is profile-bound here: the selected encoding/quality profile controls the mapping used by calculator and reference table.

Keep the same profile in both directions to avoid mixing lookup systems that use different size mappings.

Method & Reference (Verified)

  • Method basis: profile-bound mapping; constants depend on the selected profile encoded in the route.
  • Profile reference: encoding/quality profile.
  • Consistency rule: keep the same profile in mirror direction to avoid mixing incompatible mappings.
