Premiere Cashing when nothing is happening.

[101exit]

Im on a mac 2019 pro Tower. 

3.2 ghz 16 Core

160gb ram

os 10.15.7

Latest version of Premiere will just cash when im srcrubbing footage, doing nothing, or watching footage. 

I have Canon R5 footage reading from a External USB 3.0 drive. 

I did notice when I have google Chrome open Premiere will cash more often. 

Scatch disk is set to another drive. Im going crazy. Please help!

you haven't told us what your graphics card is...  If premiere crashes more often when chrome is running, you might try disconnecting from the internet either by pulling the ethernet cable or turning off wifi. And try running Premiere without any other programs running.  Do you have any external devices connected?  audio interfaces, control surfaces, etc?  if so, try disconnecting them.  Not saying you have to work this way, but let's try and narrow down the possibilities.  Try creating a new user with administrative privileges in system preferences: users and groups and log out and sign in to the new user and see if things are any better.  Do you have multiple monitors connected?  try disconnecting all but one.  Please try these things in a systematic fashion and post back with the results.  Lots of stuff to try...  and when you say you have the latest version of premiere, what version is that exactly?  And you might try installing premiere 2019 and see if that works any better.

I have (2) graphics cards. The AMD Radeon Pro 580x Running (1) monitor. and the AMD Radeon Pro W5700X running my other monitor. In my system report is says the 580x is for Display Control, and the w5700x is the GPU controller. 

It's Premiere 14.7

I do need the internet connected while working as I need to listen to royality free music while editing. I need to see the edit with music choices without downloading the music. It's a much quicker process. 

and yes, I have the UA apollo Twin 2 interface. Not sure it would be that.

this is about troubleshooting, not day to day working so why I understand some of my suggestions may not be practical in the long term, we need to try them.  Once we isolate the issues, we can either find workarounds or solutions...  First, there have been reports of issues with having 2 graphics connected.  I really don't know about any issues with 2 graphics cards but worth a shot to see if  disconnecting one might solve the issue.  . and try disconnecting the audio interface.   there have been many reports of issues when the audio hardware setup in the premiere preferences is not setup properly.  Tell us how it's set up and maybe see about changing some of the settings.  Seen a number of reports that setting the audio input to "none" can help.  And it might be the combination of issues.  so it's never easy to troubleshoot these problems from a distance.  Besides my own production and editing, I provide support for a number of clients working in premiere and in these crazy times I use zoom and teamviewer to work thru these sorts of issues.  We can usually solve these sorts of problems...

I may have discovered the issue. 

Im using Canon R5 footage. HEVC H265 4:2:2 MP4 footage. 

I don't think Premiere can handle it. I noticed once I start to layer the footage things get iffy. 

Is this possible?

and I'm on such a beefy machine. thoughts?

[Michael Grenadier]

HEVC is extremely compressed to give high quality in small file sizes.  Transcode to a larger file size format without these issues like prores422

That was my first thought but I need to stay away from Transcoding. To much footage (4 days worth), to much time (To Transcode), to much TB (Already at 2TB) . I need it to be linier. Silly the small Canon R5 can play back the 8K, 4K 120 or 4K 24 so smooth. but a large computer cant. 

Will there ever be a Adobe update to have this play back smoother?

did you ever try the things I suggested in my earlier post?  You probably should be getting better performance.   you might try using an SSD drive rather than a spinning hard drive.  And how full is the drive.  You should leave a minimum of 10% free space (and more would probably be better).  Try moving a couple of clips to the internal drive and see if performance improves.  And gotta say, it's always smart to test your workflow with new formats before digging yourself too deep a hole (this is the voice of experience speaking).   There's lots of stuff to try but not much point unless you're gonna approach it in a systematic fashion..

I did try and nothing really worked. 

I will try a external SSD when I can. I'll need a 4TB external SSD which are farily pricey. 

I did find this:
