[Premiere] - Playback glitch when speed ramping over 800%?

Hey Guys,

 

I have been encountering glitches in playback while trying to speed ramp over 800%. The project is being edited by a windows user and then he is archiving the project and sending it to me where I then open it and finish it. The glitch happens during any playback or scrubbing in the timeline and it is glitching to an entirely different clip than the one I am trying to ramp.

 

I have deleted all of the cache files and have even tried starting a brand new cache file for the project but nothing seems to fix it. I have been working with this windows editor and this workflow for over a year and have never encountered this until the most recent projects. We are both running CC 2020. Any advice or possible solutions would be greatly appreciated. I have attached a sample of the glitch below.

          I had a very similar problem with speed ramping, but when I exported the video the glitch wasnt there in the export. Try rendering the clip on your timeline and see if that helps!!

          Upon export, It does playback correctly. But I'm not going export the project every time I want to see how a ramp works haha.

            When you export to an H.264 file the hard drive speed required is the same as any other H.264 video clip. When your are playing back form the timeline with the speed at 800% the hard drive has to work much harder. I am not saying it is the hard drvie but it could be. An M.2 SSD should be OK but a SATA drive perhaps not.

            Does the problem remain if you render the clip?

            No, Upon Rendering I simply get a freeze-frame the second it breaks the 800% barrier. You can see in the example it plays fine during the ramp-up but right at 800% it freezes for the remainder of the playback.
