This has been covered a few times with several different variations to it and different solutions. I've included an example in the video below. To illustrate, everytime I clicked anything on the timeline I immediately started making circles with the mouse, so you can see how long the delay/lag is.
I've trashed my preferences and cache, made sure there's a lot of space on the hard drive that I'm working on, closed essential graphics and force quitted the Adobe 'CCXProcess'. Trashing the preferences speeds things up a bit for a while, but then not long after the lag begins. Any ideas?
Huge thanks in advance. It's driving me mad!
Premiere Pro CC 2021
MacBook Pro (Retina, 15-inch, Mid 2015)
maxOS Big Sur V 11.4
Processor: 2.5 GHz Quad-Core Intel Core i7
Memory: 16 GB 1600 MHz DDR3
Graphics: AMD Radeon R9 M370X 2 GB
The media files are on two drives. The proxies are on one external drive with the project and scratch disk, and the RAW files are on another external drive. Both are fast and connected via USB C to USB
I've been getting this issue with all projects recently.
I have reset the preferences and cache files. It works for 5 minutes then the issue starts again.
Any thoughts Kartika?
Exact same thing is happening to me. When dragging clips around the timeline, after letting go, the mouse will freeze for a few frames. It makes editing extremely annoying and frustrating.
Here's the video, bigger!
I fixed this by downgrading to 15.0.
I see that your costume workspaces are still in use. That makes me think either the preferences hasn't been cleared properly or Premiere Pro is using the workspace that's stored with the project file. Please try the following:
Let us know the results.
