Premiere Pro CC 2017 suddenly "rendering required files", VERY slow responsiveness [SOLVED]

[hqhempen]

Hi all, Hit a very random issue with Premiere Pro CC 2017 after several days of editing where, suddenly, Premiere was prompting that it had to "render required files" every single time on playback, regardless of how many times I pre-rendered the timeline. On top of that, playback and jogging was nonexistent and incredibly slow. The "required files" dialog is almost always something to do with Premiere needing to preview the AUDIO correctly, not the rendered video clips themselves. I recalled having a similar problem in the past, and sure enough, deleting all the muted audio on my many clips fixed the issue. Turns out one of the clips was a very sped up video for a timelapse - I remember that Premiere has big problems playing back super sped up audio, even if it's muted. If you're running in to this problem, be sure to DELETE all your audio and work out the kinks over which clip is causing the hangups. Hope this helps!

Thanks for taking the time to write that out, I'm sure it'll help somebody!

I recently had the sudden rath of "rendering required files" hit me and none of the solutions on the forum quite worked for me but wanted to share what i discovered in case it's helpful for someone else. In my case i had a project that I had been working with for a while with no issues. It did contain a couple audio speed changes (slight audio slow downs of a couple percentages - with maintain audio pitch UNCHECKED). Anyways... i opened the project up (after not working with it for about a month and after a premiere upgrade to CC 2020.  Suddenly any sequence i tried to play would trigger the "rendering required files dialouge" (always rendering audio files). Initially i assumed maybe it was the app version so i downgraded back down to CC 2019 and the issue persisted.

What seems to be the culprit in my case was i had started using some Native Instruments audio software on my machine and had installed various plug ins for that. On another forum i had found someone mentioning audio plug-ins not registering properly being a potential issue so I went to try that via preferences/audio/audio plug-in manager - i did the plug in scan inside there and unchecked all of the non apple plug-ins (everything else was for the music software i mentioned) and then i restarted premiere and the issue was resolved. My best guess is that premiere must have been automatically reading these VST plug-ins from the library/VST folder i had installed (for the other app) and it was causing this non-needed render. Either that or it just needed to refresh the existing plug-ins? Don't know for sure, but i never had any similar issue until the recent plug-in installation. Wanted to throw this out there in case someone else was hitting their head against the same wall i was.
