I have a MacPro Desktop computer:
Model Name: Mac Pro
Model Identifier: MacPro6,1
Processor Name: 6-Core Intel Xeon E5
Processor Speed: 3.5 GHz
Number of Processors: 1
Total Number of Cores: 6
L2 Cache (per Core): 256 KB
L3 Cache: 12 MB
Memory: 32 GB
Hard drive: 512 GB SSD
I was able to edit multicam perfectly for over a year on this machine, mixing 4k and 1080 footage with no issues. Recently I have been having playback issues on just a single clip, where if i even try to speed up the play back, it will almost freeze the video, but keep playing audio. It seems to do this for almost every format of video I have put into it. I uninstalled Premiere and reinstalled it, but that didn't fix it. I gave it more RAM, nothing, cleaned all my cache, still nothing. Is there a known bug or issues that causes this?
