1 Duration (hours) =
9 File size (GB)

Explanation

4K 30fps @ 20 Mbps uses 20 Mbps (2.5 MB/s). GB = (hours x 3600 x 2.5) / 1000. With input 1 h, result is 9 GB.

For Duration to File size, the active encoding/quality profile determines the conversion constants applied to every value.

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.
