Just to let you know the end of the story…. The film was broadcasted end of 2012 without further complains, so I guess it`s safe to assume it passed QC. Before that, the editor complained when he was doing the master, he felt the mix was to soft. But the audio-department from the TV stated upon request, they prefer softer mixes as bringing up volume is not an issue..
Good luck you all and thanks everybody for interest and contribution…Cheers

To end this thread from my point of view, I wanted to let you know how it went, at least for the mix (QC has not reported yet). We used WM loundess meter and Dolby 100 (both plugs) and made a record with an approximate setting of compressing/ limiting. That setting proved to be -20 LUFS on WLM (Waves Loundness Meter) and -21 LUFS on the Dolby. So we made a second run with 3dB less gain in the maximizer:
-23 LUFS on WLM and -24 on Dolby. Because of TruePeaks of -2,6 dBFS we lowered the overall volume 0,5dB and now we hope that we are good with that… -
Hello Jean-Christophe,
merci beaucoup for this great answer. We will check the demo of LM correct tomorrow.
Your mention of ATSC A/85 puts another spell to my misery. However I had the impression that my specs asked to be meter the loudness across all channels (except LFE) and average across the entire segment or clip.
What you are refering seems to be implemented as automatic feature in the Dolby LM 100..
As I read, LUFS and LKFS is the same since march 2011, only the names are different (ITU startet with LKFS, EBU took the idea and put some changes in, named it LUFS, but the changes where later on adopted by ITU, hence it is the same now).Cheers

Mh, thanks for participating in the quest. I read somewhere else that LKFS and LUFS are almost the same, at least in our case. But my problem is that the specs require the loudness to be averaged across the entire segment or clip and I’m looking for a way to do this.
And to make things more complicated, we are mixing for cinema and doing a downmix for TV afterwards, so anyway the loudness is different right now.
