Sounds like the high bit rates are probably the issue rather than high pixel sizes. Using shadow files or converting the clips to MagicYUV will make a noticeable difference in PD's editing response, but each requires some processinf time upfront before you can start on the editing.
It might seem counterintuitive to use an intermediate codec like MagicYUV with a much higher bitrate (as much as 1.5Gbps) when I just said that the bitrate on your existing clips may be why PD slows down, but the difference is that MagicYUV clips are not encoded and can be loaded/previewed/skipped/displayed instantly. The main downside is the much larger drive space needed but that probably won't be an issue with your system.
I put together an app back in 2015 with the help of other forum members to make the process of converting clips to MagicYUV as easy as possible, and here's a link to the original OneDrive
folder with the installer app I made.
Some things to note: MagicYUV is now at version 2.3 and you'll probably want to get the latest version from
here. The Standard version is all you'll need to work with PD.
There are also updates for VirtualDub2 that's needed to convert the clips with the custom project that's included with my app. You can update VDub2 from
here.
Run my Magic+PD(x64) installer first to get the basic components on your system, then update the MagicYUV codec and VDub2 before you start converting. Let me know how it goes!
