What is your system, and what were you doing at the time this appeared? What's your media and any effects used also ...
Hi Neil, I did not get any notification of this answer! It happens to me when I press "play" to see the videos that I add to the project, so I can't work because it doesn't let me see the preview in real-time.
iMac (27-inch, Mid 2011)
Processor 2,7 GHz Intel Core i5
Memory 20 GB 1333 MHz DDR3
Boot disk Macintosh HD
Graphics AMD Radeon HD 6770M 512 MB
I don't know if it has to do with anything, but this happened after I did the last upddate
Ouch ... that's a nine year old system. Premiere 2020 has been re-coded to modernize much of the code base, and it's not playing too well on gear over about four years old. I think that could be the problem actually.
haha yes, I also imagined that that could also be the problem, so what I'm going to do is go back to a previous version, because this problem appeared now, thanks!
I'm getting the same error (specifically Device controller 4). I have an 8 year old system:
Model Name: Mac Pro
Model Identifier: MacPro5,1
Processor Name: 6-Core Intel Xeon
Processor Speed: 3.33 GHz
Number of Processors: 1
Total Number of Cores: 6
RAM: 24 GB
System Drive: 525 GB SSD
At current price to value points, I'll not be buying another Mac...maybe ever.
I get that error repeatedly so far with no effect on functionality. System is solid, reliable and steady.
Does this mean they plan no debugging for older pro systems?
Older gear is not going to be supported ... and that's partly to keep up with changes in vendors, partly because writing something that can support every flipping bit of code across 5 gazillion generations of computer gear means a more massive program that will have more instability issues.
The actual code needed to run the older gear is different ... that's part of the issue. And they're going to drop the older code from the program.
