Faster warp stabilizer through multi-core analysis
At this moment warp stabilizer seems to only use one core of the CPU to "analyze" the footage, and because of that takes an extremely long time. The usual workaround is to split the video into several pieces, up to the number of cores the CPU has, but then stitching them back seamlessly is a very difficult task. Why can't Premiere virtually split the video in an optimum number of pieces of equal duration, analyze them all at the same time allocating one core for each, and them aggregate the gathered data to stabilize the whole clip in one process?

The warp stabilizer effect got optimized quite recently. When enabling the new "fast analysis" checkbox the analysis will use several CPU cores.
It still does not use the GPU or 100% of your CPU cores, though. What you can do is analyze two or more clips in parallel. This will utilize 100% of your CPU. If you want to automate this you can use the Batch Stabilization Analysis for Warp Stabilizer plugin:

Having a 3990x is useless when this feature only works with one (1) Core.

Please wake up Adobe it's 2020. Warp stabilizer needs to use all cores.
