Timeline WONT STOP playing ?!?!?

Same thing here. I am still praying for an Adobe Miracle Pro Solution...

I'm also having this issue the last 3 years. Every time I'm suffering to do cc cleaner tool or even reinstall windows

July 29, 2021 I am having this issue. All my drivers are up to date and I have a fresh install of premiere pro. The issue is very significant during playback in multicam view. Using 4k proxies.
Intel I7 10750h
32GB ram
RTX 2060

I can not edit this way. Playback will not stop for 5-15 seconds after I hit stop and the program is unresponsive. Any multicam cuts do not happen until where the playhead finally stops.

I'm having this issue this week. The last two days have been painful. It's a real shame to read through a thread like this and see that it's an issue from 2017 that still hasn't been fixed. 

This has got to be the most aggravating issue of the multitude of Premiere problems.  I realize that with a program this amazing that has to address evolving technology, there are always going to be issues to work out (though *bloat* and useless "features" has become one of the greatest issues of all), but when you have an editing program that CAN'T start and stop without lag, the software becomes pretty much useless.  I cut to music, and without being able to start/stop exactly on the beat, editing a two minute video can become a multi-hour process instead of a half hour endeavor.

The ONLY current solution to this problem is going all the way back to Adobe Premiere 14.2.  This is the "newest" version that absolutely does not have the timeline start/stop issue.

I am currently using a computer with an i7 10875H processor with 8 cores/16 threads, 64GB RAM, a Quadro RTX 3000 GPU, and the only drives involved are NVMe drives that never exceed 50% capacity (OS, footage, and cache/previews are all on separate drives).  On most videos I use *only* Lumetri and no other plug-ins or FX.  Most timelines are only 2 minutes long with only three video tracks and one stereo audio track.  The footage is H.264 from various Sony A7III's and Panasonic G9's, but only from one camera (ther diffferent codecs are not mixed).  The footage is 59.94fps and the final two minute composition has most if not all of the footage run at 50% using the speed/duration drop down.  I realize a better way to create slow-mo is my "interpreting" the 59.94 footage as 23.976, but when you do that you have to go through all the footage in slow motion (vs. regular speed) and that is not acceptable for the amount of footage that needs to be culled.  Regardless, if the "slo-mo" is the issue, then Adobe needs to address it (long ago), because running footage at 50% speed shouldn't be any trouble at all.

The fact that this is an issue is absolutely inexcusable.  The fact that this has been an issue for YEARS should be a massive embarrassment to Adobe.

Logging in to shout out a solution I had - hit the Enter key to pre-render your clip (the action is called "Render Effects In to Out"). This solved any laggyness I had when trying to play/pause during playback.

The problem I was having was similar to the other users here: I would start playback, and attempt to stop it at random points on the timeline - most spots would either have a delay before fully stopping playback, or if it was currently playing a nested clip, it wouldn't stop playback until the end of the sequence, or be severely delayed by a matter of 10-15 seconds.

I believe the problem came from the multiple nested clips I had in the timeline that weren't pre-rendered, so I'm sure that Premiere had to process and render them every time the timeline tried to run through them. My guess is that pre-rendering those nested sequences took that load off of Premiere and it allowed for much smoother playback. (this is coming from a guy who has no knowledge of the inner workings of Premiere, so take this with a grain of salt).

Worth a shot.

It's bonkers that this issue still exists.  My goto solution over the past year has been to use version 14.2 (the last version where this was not a persistent issue).  I started working with a new mobile workstation from the road (i7 10875H, 8 core/16 thread, 64GB RAM, Quadro RTX 3000, only working from NVMe drives), so I decided to give the most recent "stable" version of Premiere a try (15.2.0 build 35).  I had no lag start/stop on the timeline for around an hour, but I'm back to it again, and no amount of clearing caches or adjusting anything in the prefs gets me back to simply being able to start/stop the timeline without major latency.  This is a simple timeline with very few effects.  There *is* one clip utilizing time remapping (I mention this because others have reported time alteration being the reason for this bug), and lots of other clips running at 50% for slow motion.  I can't believe I have to reinstall version 14.2 on my new machine, just so I can start and stop the freaking timeline without a delay. 

Mod note: Address Adobe devs by filing a bug here.

Hey guys, this platform is like a time machine. The problem is starting from 2017.  Don't worry  if it is not solved in 2017, today is April 2021 and the problem is still here . Most probably some one will reply to this post in 2025 with same problem. 

I am using proxy files in order to fasten up the process but timeline still does not stop in April 2021 .

Dear Adobe, when this timeline will stop? 

The absolute cheek that someone has marked this 'solved'. It's not solved. I've been using Premiere for so many years and this problem persists. It starts out of the blue and spreads through my projects like a virus. It's started happening in a project I've only been working on for a couple hours. I've missed so many deadlines and pulled so much hair out for this particular problem. Running very high end professional setup. Tried all the fixes. 

Year after year. I've got a deadline on Friday and I just know that this time in 24 hours from now I'm going to be stressed to the max because every time I press play it won't stop playing for +/- 30 seconds. It is degrading to my work and my mental health. Multiple systems. Multiple projects. Sometimes it happens on light projects. Sometimes heavy ones. No rhyme or reason. 

We are professionals here, I wish you were, Adobe. 

I am a long time Premiere Pro user and I keep having this problem. I'm currently on Windows but have had the problem on Mac for 8+ years.

The hardware is more than adequate.

I have tried all the recommended solutions, sometimes with success sometimes without.

• Lock/unlock audio layers
• Delete all caches
• Renamed config folder to have Premiere create new ones
• Used only one display
• Deactivate hardware acceleration de-/encoding
• Reset settings during start-up of Premiere (ALT+SHIFT on Windows or OPT+SHIFT on Mac during start-up)

Even done even the pram/vram voodoo non-sense on MacOS 😉 

My current best solution that works most often is the following:

• Remove all time reversed clips.

Even though it solved my current problem, it's time for me to switch to DaVinci Resolve. I can't afford to use a non-functional software just before a deadline.
