Hi Tony - my memory is worse but I seem to recall that you did some tests and shadow files were very low resolution only which may not be ideal for some editing 4k. The advantage to Magic+PD is that you can smoothly edit 4k with 4k relatime preview.

Proxy editing is suported in many NLE programs and the user can specify the proxy resolution. Eg if you are editing H.264 4k you can select H.264 1080 or 720 HD proxy resolution. The program automatically generates the proxy files, uses them for edit, and exchanges them for your original 4k files to render 4k out. Proxy editing implies using a lower res file to edit.
Magic+PD uses a process called Transcoding which is now used in many edit programs as an automated process which converts the highly compressed H.264 4k camera files into a decompressed file using an intermediate edit friendly codec which substantially reduces the edit program workload and provides full resolution preview. In other programs you can select a codec like Cineform, DNxHd, MagicYUV, etc and it will create transcoded files prior to edit. For example the free editor GoPro Studo forces the user to convert GoPro H.264 mp4 files to Cineform prior to edit. Transcoding is also common practice in professional post producton edit workflows. PDR doesn't support Transcoding so users created Magic+PD to enable 4k editing on a home PC. It's not perfect, but it works, and may be worth a try
