Lagging playhead when ripple deleting on long timelines with +2000 cuts from the same source video

Hi,

I have a projects containing over 2000 clips (basically it's the result of a 2 hour video chopped up into 2000 cuts). The playhead gets laggy when ripple deleting clips on the timeline.

I noticed it doesn't happen when I have let's say 500 clips from a chopped up video.

So I think it might be a hardware bottleneck somewhere.

The videos are 1080p 30fps.

Basically the chopped up sequence with over 2000 cuts from a software that removes the silences and spits out an XML file with all the corresponding cuts to finetune and import into Premiere. This is the file that creates the sequence in Premiere.

----

My current hardware:

* i7 5820k (6 cores /12 threads intel cpu)

* 64 gb of ram

* GTX 970 gpu

* Storage set up:

- Separate internal Nvme drive for OS/Software including Premiere

- Separate internal SATA SSD for cache/previews

- External HDD for project source files

- Internal SSD for export files

----

The source files are read from a HDD. I tried reading them from an SSD to see if that improved the playback but it doesn't.

I use Windows 10 and Premiere is up to date.

CUDA accelaration is enabled on Premiere.

----

I upgraded the RAM 64GB. The performance issue with the lagging playhead when ripple deleting on long timelines with many cuts persists.

I've been trying to edit splitting the project into chunks but it's really inconvenient because I never know when I should split the files in order for the playhead to play smoothly and I have to be very careful not miss any sentencences between the cuts. I don't think I can do this without going crazy. The thing is all my projects are like this. long 70-130 minute videos chopped up into 1500-2500 clips (result of all the silences removed).

 

I'm seriously considering upgrading the hardware, I would have to do it sooner or later anyways.

I need a CPU/board that allows for multiple capture cards so PCIE lanes are very important for me so I was thinking about getting Threadripper Pro 3955WX (allows up to 120 pcie lanes) along with ASUS Pro WS WRX80E-SAGE SE WiFi board (has 7 full x16 pcie slots).

I will keep the 64 GB of RAM, the GTX 970 GPU and the storage set up as it is for now since it seems the CPU is the most important component. Let's see how it goes.

 

The Threadripper Pro 3955WX has 16 cores/32 threads running at 3.9-4.3 Ghz.

Do you think this CPU will fix the lagging issue when working with timelines with +2000 cuts from the same source video?

 

I appreciate any suggestions or guidelines.

 

Thank you.

I have the same problem with 128 Gb of RAM, an RTX 4080 and 4 SSD.

Adobe doesn't give a damn, they keep adding features no one asked for and the stability is getting worse over time.

That's exactly the reason I switched to Resolve and even with 2500+ clips on the timeline, the playback is instant.
