dialnorm, how do i set it in prem pro?
I have a project going to tv broadcast (music video) and the requirement is for the dialnorm to be at -24dBFS…how do i set it? Can i just roughly set it to where it looks like it’s averaging that level as long as my limiter is set?

Dialnorm is quite a bit different than that. It’s the “absolute value of a power sum of the A-weighted audio level in all digital channels” and any broadcaster I’ve dealt with usually measures it as dialog/voiceover only.
https://www.channld.com/audioleak/ is probably the only non-hardware based way I know of to easily measure dialnorm.
It’s basically the amount of “power” in dialog… the main chunk of volume in dialog hangs around -24db with occasional peaks (depending on how compressed the signal is). It’s a decent indicator of overall program volume as music, sound effects, etc are mixed around dialog levels.
With a music video you should get a recommendation from your broadcaster. Music tracks are usually mastered “hot” which means it’s consistently powerful with a good amount of compression… and you can’t really judge dialnorm off of it.
-10db tends to be the max audio level, but your broadcaster might have you normalize audio to -18db or something as a compromise to dialnorm.
… yes, dialnorm is hard to understand, but it’s simply a measurement, not a program setting.

If on Windows Nugen makes a VST plugin that measures ITU 1770 loudness. It works in prPro and can be applied to dialog tracks in the Mixer.

I was all excited until I saw the $999 price tag.

It should also be mentioned that I based my answer against hardware based solutions like Dolby’s LM100 that uses Dialogue Intelligence technology.
If you have clean, dialog only/dominant audio then your world opens up.
But yes, in general there are some software meters like Wave’s PAZ, Sonoris Meter, and so on that will show A-weighted results.
I like Audio Leak since it shows a graph over time rather than a live readout.
Alternately, if you have Adobe Audition you can apply an FFT filter graphed using the table from https://www.diracdelta.co.uk/science/source/a/w/aweighting/source.html (at the bottom) and then read the Average RMS in the Amplitude Statistics window.

I don’t know where you got 999$. I see the VisLM-H plugin for 449$ on their site.
