position of height objects of Dolby ADM 7.1.4 when imported into EPS #283

Open WernerBleisteiner opened 5 months ago

WernerBleisteiner commented 5 months ago

Just an observation (you may be aware of anyway) or just question: Tried out some new variations of BLITS in 7.1.4 in DaVinci Resolve NGA authoring these days. When the Dolby bed is only applied as 7.1 and 4 objects are panned as height speakers in all top corners, these objects get imported from the exported Dolby ADM at azimuth 30º elevation 54.6º in EPS. Is that intentional? Or maybe still under discussion at ITU in the loudspeaker labelling or other ADM issue?

The corresponding rendering layout 4+7+0 in EPS has the correct positions. Attached a screenshot and the exported Dolby ADM xml.

Maybe the object positions there are not correct ? Wouldn't the corner imply positions "1" instead of "0.5"? Or do the Dolby specs differ?

Thanks
