Display the degree of correlation at the adobe premiere audio peak meteringOpen for Voting

Hi Adobe Team,To deliver great video products it would be very handy to get a audio phase correlation meter directly at the audio meters next to the sequence.Checking the phase correlation is mendatory and right now in premiere pro several clicks are required to display it. Another solution would be to add hardware but we would like to get rid of hardware and also not having additional clicks in the software 😉How this could look like: (RTW PPM 1206D)Details from RTW regarding the phase correlation meter:https://www.rtw.com/en/blog/focus-the-multicorrelator.htmlPhase CorrelationLet's start by understanding the term phase correlation and how we typically show it in our meters.Mostly, phase correlation is used to determine the mono compatibility of a stereo signal, but depending on where you use it, it can also reveal other things, such as bad microphone placement.The term phase correlation refers to the phase relationship between two sources, and with a phase correlation meter, you get a simple view of the changing phase relationship between those two sources.There are three main ways two sources can relate - and anywhere in between.Identical: They are 100% identicalUnrelated: They don't relate at all and have nothing in commonSwitched Polarity: They are identical, but one of the signals has its phase invertedIn a phase correlation meter, these three stages are normally described on a linear scale going from -1 (switched polarity) over 0 (unrelated) to 1 (identical). The numbers -1, 0 and 1 are not randomly chosen as they are the cosine of the angle of degrees of the phase difference between the two sources.Phase relations below 0 are shown in red and relations above 0 are shown in green.If left and right channels are identical, there are zero degrees of phase difference between them, and since the cosine of 0 degrees is 1, that's what the meter will tell you.If left and right are different, unrelated signals, the phase correlation between them will be 90 degrees and the cosine of 90 degrees is 0.And if left and right are the same, but right is inverted, the phase difference would be 180 degrees, and the meter will show -1, which is the cosine of 180 degrees.Normal stereo mixes usually show correlation values between 0.3 and 0.7.Many thanks in advanceAndreas

Warning: PP doesn't work for feature length projectsOpen for Voting

I felt the need to get this out of my system. And I want to hear if others experience the same things. Am I just going mad?  I am fluent in both Premiere and Avid and i've been using both for around 15 years. At the moment I'm editing a feature length (around 2-2,5 hours) film. It's the first time I'm editing a feature in premiere (all of my previous features I've edited in Avid). And here are my take aways: It doesn't work. I feel confident premiere is NOT made to work for theese kinds of projects without big workarounds to just run. Let me alaborate. The last film i did in Avid i used a Mac mini M1 with 16gb of ram. Sure there where times I wished I have had a faster and better machine, but it worked. For my current project I had to upgrade to the latest Mac studio M4 Max because premiere where so laggy. But even now, every edit i make, every trim in my timeline - heck even when I just scroll on the timeline - there is lag.  It got even worse with the latest update. I had to downgrade to the previuous version which helped alot. But there's still lag. Every save takes around 15 seconds. And with every lag I'm longing for Avids smooth easy, lag-free experience with quick save times. I've tried emptying cache. And it makes it a little tiny bit fast for a while. My feeling (yes, I don't know code or software engingering) is that there are to many, for film editing, unnecessary functions. Sure, they may be very handy when editing quick short form projects, but are just weighing down the softeware on longer formats.  Adobe should really consider, if they want to keep feature film editors, to develop a stripped down version of premiere pro. Maybe starting from scratch. Re-imagined. Maybe you could let people choose which functions they need.  I will never use premiere again unless MAJOR changes are made. If anyone can relate and have figured out solutions PLEASE share. I've still got time left with this project.
