Warp stabilizer severely slowed down project

[Zoooooom92]

Hey guys,

So I have a pretty basic project of just a multicam sequence and a timeline that's about 1.5 hours of a commencement ceremony. My main camera the video ended up with lots of jitters and shakes because I was shooting from some aluminum bleachers and if people walked or moved at all, you can tell in the video.

So here I am, I chopped up the main shot into the clips that need warp stabilizer the most and I applied it to those. Obviously this takes forever to do so I let it run while at work. 

Now when I open the project, I can't even do anything after that, the project is incredibly slow, nothing loads, and it's a headache. So warp stabilizer seems to have been successfully applied to what I needed, but since then, like I said, the project seems unusable. 

I have an AMD 3900x CPU, NVIDIA 2070 Super GFX card, and 32gb DDR4 Ram. 

Any tips on what to do or how I can even begin editing? Was hoping to finish the project already but I can barely even open that file...

First, I'd dump the all the cache/media cache database files before opening Premiere.

Then I'd remove Warp from many of those clips if not most. In the Sequence settings, set your preview codec/format to a full intraframe format like ProRes422 or Cineform. Then apply Warp to a very few, then do a complete render/replace to replace the original clips with clips with Warp baked into them.

Work your way through the project.
