Performance Issues: slow vs fast scrub of timeline

So I have a 15min long mini-doc I'm mastering.

It's 6 tracks of video and 9 tracks of audio. Rather dense; fair number of cuts.

But everything is rendered from start to finish.

In my Avid Media Composer days, a fully rendered timeline is equivalent to a performance boost

where scrubbing the timeline is faster and more fluid.

But with PP I find it very sluggish and choppy.

I have have blamed this, somewhat, on the fast that all the footage and projects are stored on a shared NAS

where other people in the office can work from the same pool of media & other files.

Pluses & minuses with the NAS. But the NAS and our workflow are here to stay.

But last night I noticed something.

I went to export my timeline and up popped the export dialogue

together with a large window showing a frame of the edit.

Normally I just select a setting and choose export.

But this time I scrubbed along inside the export window

and it was scrubbing like a hot knife through warm butter.

Super fast. Super smooth.

So much better was the experience I thought - did I upgrade to a new OS or something?

I closed the dialogue and went back to my timeline and still really sluggish.

Back to export window - super fast.

So I ask...what is going on here?

Have I been experiencing a performance issue all this time and blaming it on my system?

Is Premiere capable of so much more?

Is this a bug?

MacPro 2019 Intel

Hey BrownFish,

Sorry for the poor experience. The Timeline has elements that require processing, which might cause the scrubbing performance to seem a bit rough. Could you check if you have the Show Duplicate Frame Markers option enabled? If you do, please try disabling it temporarily and let us know if the Timeline performance improves.

Thanks,

I confess that I eventually went there. I had forgotten how debilitating showing dupes is on the timeline performance. And, yes, it made a pretty good speed jump - enough to have prevented me from posting about it had I remembered it before. But still... not as smooth and rapid as the Media export window after things have been rendered.

Slightly off topic but I have long had an issue with PP forgetting it's renders after I quit the software and return. From Day 1 of using the software in Jan of 2020 this has been the case. Sometimes it remembers but most of the time it forgets. This isn't to say when I re-open the project it asks me for missing media - it doesn't. It has simply forgotten it even did it. My timeline is a sea of yellow performance lines on top. I mention it because it is still related to performance and smoothness of flow. As I never get any response to my frustration about this in the forums, I has reigned myself to re-rendering my timeline each and every time I return to a project. In other NLEs that would be ludicrous. I mention it now in the hope there may be some insight. Is this normal for PP? Or does anyone else experience this?

I tried a screen recording of what's going on.

Here is the timeline and me clicking through it and trying to scrub then trying to play. It all works...just very sluggish.

Note the entire timeline is rendered.

And here is the export window of the exact same timeline with me scrubbibng and clicking play.

I've tried putting on my programmer's cap. But I just fail to see why I can't get the same responsiveness out of my timeline.
