I think it's related to the Lumetri Color portion or scaling of the GH5 4K Anamorphic footage (2:1) at 4K resolution in 10-bit @ 400Mbps ALL-I mode. I have not tried applying the Lumetri color Effect to an adjustment layer instead of the main clip because i don't want to color correct everything, just the source clip.
I have plenty of system RAM. 32GB with Premiere taking up 14GB currently.
Adobe needs to investigate this. CPU is sitting idle, pretty much idle and I/O is doing virtually nothing. It sounds like either a memory leak or a very un-optimised routine that is running for the scaling operation of the footage.
Doesn't seem to matter whether i export and queue to Media Encoder or Premiere itself does the export.
Can't render this with software mode only will take even longer.
Also, Applying any other effects on top of this, just breaks everything due to being so resource intensive.
Just as a side, i tried rendering in place on the timeline. It did finish! however did not output the correct Aspect ratio for the Anamorphic footage in the timeline. The footage was not properly scaled or did not maintain all my zooms i had edited in, so the render and replace finished the render but I didn't get the results i was expecting. This was only with Lumetri Color on. The render still took a very long time, but no where near the length of time this is taking now.
This was also after a fresh reboot.
I'm 21 hours into a render that shows 10% completed and 188 hours remaining on the clock.
(That's just for rendering out to intermediary codec Cineform in .mov file on PC)
I still need to apply noise reduction software to the footage.
Just don't understand the lack of using system resources and the fact that the file size of the target file has not increased either (its still showing 1 KB)
Also was curious --- I have not applied microsoft's new patch for the CPU leak problems yet - KB4073290 (it also fixes Symantec Anti virus apparently), will this have any effect after applying it - better or worse for audio or premiere support?
This definitely feels like an old problem that Adobe has that has resurfaced for Lumetri or Effects. I seem to recall 2014 or 2015 having similar issues at one point. Am i pushing the system, yes, at the moment though, no because the resources are not being used.
Whats frustrating is that i've been plagued by computer performance for the last few months as Microsoft has continually been putting out patch after patch affecting my Audio MSIO Creative 0404 USB XLR input device, on top of that, Nvidia driver updates as well as Adobe patches along side all of the other system applications that get updated. The system is hard to nail down to getting stable. Its at that point right now that it is stable except for this render problem. There is one microsoft patch to go in however i am holding off until i can figure what this latest issue is.
I hope they run some performance tests soon and release some appropriate patches to address this.
I am nearly at my witt's end trying to get this one video rendered. I may need to look at Davinci Resolve Pro..
