[Help] Very Slow Previews even in 1/4 - 16core CPU/1080ti

[MK93]

Hi all,

Having crazy issues with Premiere. When trying to preview footage from my HDD (should i move current footage to SSD?) it is very choppy unless I play through the footage few times. The main timeline footage is also choppy unless i am replaying small sections or render in-out.

Any ideas?Here is a video of the issue - https://www.dropbox.com/s/n6nectf69twzsjr/Adobe%20Premiere%20Pro%20CC%202019%20-%20F__Dropbox_Mister...

Using 4k VFR long-GOP media is a drag on most machines. HEAVY CPU/RAM demands. That's at 'standard' rates of say 23.976 or 29.97. If that's progressive media, so it's really 60fps ... you've not only got a ton more pixels per frame than 1080, you've got twice as many frames per second.

An internal late-generation SSD drive for media might be a good choice. Also ... if you haven't already ... go into your bins after importing this media and right-click/Modify/Assume frame-rate of X ... and set that to the frame rate of the setting in the camera.

Then ... use that modified setting media on a new sequence, see if it does a bit better. You still might need to use proxies to get this working smoothly.

Apologies delayed reply. I will attempt to do this tonight. However I have fairly beefy machine as shown in the OP. I might have to rethink how I distribute the files/cache/active disks between my SSDs.

I am using M.2 from the main drive, the footage is on a HDD (64MB/7.2K RPM) and cache/scratch is split between the two SSDs. I even tried moving the footage to an SSD instead.

But Il go ahead and try the above and go from there.

Thank you for the reply Neil!

You will see a nice boost in performance if you move your media onto the SSD and just use the HDD for archiving.  It's best to have your O/S and applications on one SSD, and the active media, project files, media cache and scratch on another SSD.  (Or split that stuff up on multiple SSDs)  With your current configuration, like Neil said, using proxies may be your best option, so check out a tutorial on YouTube if you're not familiar with that process.  Or, just keep rendering in/out as you go.  4K is just a lot for any computer to handle.

One more option: download and install Adobe Prelude.  It should be part of your Adobe Creative Cloud subscription.  I can't explain why, but playback is much smoother in Prelude than Premiere, so you can do the majority of your work in Prelude like setting in/out points on your clips and putting together a timeline (called a rough cut in Prelude).  Then export the rough cut into Premiere Pro, drag it onto the sequence, render it, add special effects and make any other adjustments needed, and export.

I wish more people used Prelude ... that app is awesome for say moving media from card to multiple spots on the computer ​while​ renaming them and maybe even transcoding one set to say Cineform for ease in editing. After you finish the project, dump the Cineform t-codes as you can recreate them at need from the original media if you need to re-visit the project. You also naturally have your backup copies made and placed as part of this.

AND ... yea, it's pretty quick to do ins/outs and make a rough sequence to take into PrPro.

If more of us used that, it would get more attention from the staffers. Which would be a very good thing.

I think issue might lay elsewhere, even when I proxied the files to 1080p I was hitting the same issues pretty much. I will have to sit down and properly set everything up and make sure there is no bottleneck anywhere in the chain.

As an "in general" thing, the OS/programs can live quite well on a standard internal SSD. Something as fast as an internal m.2/Nvme is best used for say projects/media or projects/cache. Then put the other (media or cache) on another internal SSD, if possible. Large spinners are necessary for some larger projects, but if you can have your 'live' projects project/cache/media on SSD's PrPro seems happier.
