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

Explanation

4K 30fps @ 20 Mbps uses 20 Mbps (2.5 MB/s). seconds = MB / 2.5. With input 1 MB, result is 0.4 s.

File size to Duration 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.
