Premiere agonisingly slow despite brand new specced out MacBook

Hi guys,

 

I've reached that point I'm sure you all have at some point if you're an editor for a living - where you just want to break down and cry because there's an impending deadline and Premiere is doing everything it can to be difficult.


Long story short, I bought a brand new specced out MacBook Pro 3 weeks ago because I took on my biggest freelance job to date, in terms of size of project and audience. And my old MacBook from 2014 was struggling, which I didn't have time to allow for.


The first couple of weeks Premiere was smooth as a baby's behind, but now the last 2 days have seen it come to a grinding halt. I can't play back mp4 videos of 100Mb sizes even at quarter resolution without it being juttery and freezing. I can't playback my timeline without it freezing or displaying at one frame every 2 seconds. Just pressing play and stop on the preview window takes ages to take action. I simply can't edit whilst it's like this.

 

Today I haven't been able to edit because of these issues and it's sending me to a near panic attack as the deadlines are in a few days time and I still have an entire episode to edit.

 

I've followed all the steps online about how to speed up Premiere, and nothing has worked. And as a final resort I'm here hoping someone might be able to have a solution.

 

My MacBook has 

- 2.3 GHz 8-Core Intel Core i9 processor

- 64GB RAM

- AMD Radeon Pro 5500M 8 GB Intel UHD Graphics 

 

I'm editing from a 4TB LaCie hard drive too.

 

My MacBook has nothing else installed on it except Premiere and AE, and has almost an empty 1TB hard drive.

 

Any suggestions will be greatly appreciated!

Thanks,
CM

In addition to Kevin and Steve's advice, have you checked that your computer is running the latest version of Catalina? Is should be 10.15.6. Sometimes computers get shipped with older versions of the OS.

    Don't know what you issue might be, though would be following Kevin's suggestion to the letter.

    I also have a 4 week old MBP 16 with almost same specs to yours and so far, under heavy use, has not exhibited any issues to date.

     

    That it was fine for you and now it is not suggests the hardware was (and likely still is) just fine.

     

    Have you tried switching to 'software only' renderer? Or even try the OpenCL renderer just in case.

     

    Couple of things I would try. Assuming you are running Premiere Pro 14.3.1 try installing one of the earlier 14 versions. You could also try the current beta build of Premiere Pro. I think this is available to everyone in the CC app under 'Beta apps'.

     

    Sorry don't have any more to offer and know this is a very stressful situation.

     

    Good luck.

    Here is the problem:

     

    Currently, Premiere Pro does not fully support any of the newest AMD RDNA-architecture mobile CPUs. In fact, with the so far lackadaisical support for AMD GPUs in general, it is not surprising that even the most powerful AMD desktop GPU, the RX 5700 XT, performs no better than a much cheaper Nvidia GeForce GTX 1660 Super. Unfortunately, the newest versions of the Apple macOS now no longer support any third-party-sourced Nvidia GPUs at all - only those Nvidia GPUs that had already been installed as original equipment on Apple Macs sold during the mid-2010's.

    Thanks for your reply, albeit I'm a little alarmed.

    Essentially what you're saying is I've just paid almost £4,000 for a new machine solely for editing smoothly, and it won't be able to do that?

    Will Premiere never support AMD stuff? Have I just wasted a huge amount of money?

    Hi Kevin,


    I've tried this and it hasn't helped. It's slowed it down further if anything is it now has to reload every file and there are a lot, so my system is spending a long time doing this.

     

    Not sure what other options I'm left with. I've tried different video rendering options, cleaning cache, updating Mac OS, new timelines, nothing is working.

     

    Sometimes it runs a little smoother than others, but sometimes it is inoperable, like right this second when I had to wait 45 seconds for it just to play back a 100MB 30 second clip.

     


    Try this if you have not already.

    Go to Preferences > Audio Hardware and set your Default Input to None.
