Essential Sound Ducking: Keyframe Generation taking unreasonable amount of time
Audio keyframe generation takes around 15 minutes for a 25 minute long program.
Trying to change audio gain while this is happening brings up the "Calculating Audio Peaks" window with an immobile progress bar, which doesn't move until the keyframes are generated, which leads me to believe this is an issue on the level of Audio Peak generation.
Have tried reducing project size, removing unused clips and files, clearing media cache and changing its location to an nvme ssd. Nothing helps.
Latest premiere pro update (12,1,1 build 10), on mac OS Sierra, Mac Pro late 2013 with no shortage of ram or cpu power. Media files are on a RAID 5 array.
We just released an update (12.1.2) that has a number of fixes incl. an update to the generation of keyframes for audio ducking. Further info is available here:
It would be great to check if this updates also covers the issue you were facing. If not, it would be great if one of our engineers could get in touch with you to take a closer look at your project, settings etc.

Patrick , this is still happening in PP 2019 13.0.3
I lay down a15 min FS7 clip with only 2 out of 8 audio tracks turned on in the interpret> audio menu
Then put into sequence and Generate Audio Waveforms from clip menu - takes 5-10min
Then press G on clip, for Gain menu
If I type some number of gain in - say 8 - it will take MUCH longer to 'calculate' than if I just leave that blank and wait until calculating is finished. Im talking like 5 minutes (or never finishing) vs. 20 seconds
Now that's a bug
