Playback is choppy and reversing

[Dzuari]

All of the sudden all of my projects are extremely choppy, laggy and skipping backwards when playingback in the editor.

I've tried clearing the cache, uninstalled premiere and reinstalled it. I have no idea why it suddenly started doing this. Here is a video of it's preformance.

you can even see the timeline guide in the timeline glitching and rewinding a bit.

I've edited on this rig for years with no issue.

Likely some auto-update is to blame: Windows, Drivers or Premiere itself. Or maybe there was some change in hw-config/connected devices that you did not mention. Think what that could be and try to roll back.

[Dzuari]

is there a way to upload hw-config?

Could you also include what version of Premiere Pro you have? Have you updated anything recently by chance?

[Dzuari]

so far I have tried proxies, reinstalled premiere pro, rolled back premiere to 14.7, updated graphics drivers, nothing has worked.

I'm really at a loss here on what to do, anyone have any ideas?

If that's not it:

Try resetting the preferences:

If that doesn't work, try resetting the Workspaces:
Reset a workspace
Reset the current workspace to return to its original, saved layout of panels.
1. Do one of the following:
• Click the Workspace menu icon and select Reset to Saved Layout.
• Choose Window > Workspace > Reset to Saved Layout.
from here:

If that doesn't work, try Preferences > Audio Hardware and set Input to None.

If that doesn’t work, try updating or rolling back your graphics driver directly from the video card manufacturer’s site. If NVIDIA, do a clean install of the latest Studio Driver (NOT the Game Driver).

If that doesn't work, try creating a new project and import the old one into it.
