My specs are in the DXDiag. I did try enabling shadow files and it seemed to help on one of the clips but not another. My system should be powerful enough going off of the specs other users have. Lowering the preview quality has no effect. I also turned off anything I could find related to hardware acceleration in both PD and AMD Cataylst. Been trying to fix this for hours now and the only posts I find either have an answer I already tried and it doesn't work or haven't gotten a response. Any help would be appreciated, thank you.

Edit: Camera is a Panasonic HC-V700K. Files are stored on a 2TB external hard drive, program is installed on internal D drive. C drive is a 64GB SSD. I also tried having all files related to this project on the D drive and it makes no difference.
