> Quoting the EBU 3341: An ‘EBU Mode’ meter shall offer two scales, for when a scale is shown, selectable by the user: 1. range -18.0 LU to +9.0 LU (-41.0 LUFS to -14.0 LUFS), named ‘EBU +9 scale’ 2. range -36.0 LU to +18.0 LU (-59.0 LUFS to -5.0 LUFS), named ‘EBU +18 scale’ When you go down to 480x102, the printed range becomes [-16;+8] LU for +9 scale and [-32;+16] LU for +18 scale (see meter option). I think these range boundaries should be preserved in the output. [...] -- Clément B.
