Final Cut slow down

Aaaargggh! Apple what have you done to Final Cut? Since the last update (s) it has ground to halt. I have tried all the things suggested previously but nothing seems to get it back to the speed I am used to.

IMac Retina 5K late 2014

macOS Mojave 10.14.2

Processor 3.5 GHz intel Core i5

8 GB MHz DDR3

AMD Radeon R9 M290X 2048 MB Graphics card

Final Cut Pro 10.4.5

Reinstalled, using transcoding media - shut everything else down on the Mac..... etc Nothing works.

Hi, I had the same issue! FCPX working fine, installed Mac OS update (10.14.3), opened up FCPX an hour later, and it was running unbearably slow. and I mean unusable slow, any action has a horrible lag. A single click takes forever to react. Theres just no way you can edit like that.

Long story short, here's what helped me. Turn off Background Rendering.

Go to Preferences in the Final Cut Menu Bar. Or if thats too slow hit, Cmd comma ( ⌘ ,)

Under Playback settings, uncheck Background Render.

That made all the difference in my situation and now FCPX is actually usable. If your playback is slow, you can render manually. Go to Modify in menu bar, and at the bottom choose Render All or Render Selection.

I'm not sure what happened w the update. Background rendering was quick and barely noticeable. But then background render was moving at a ridiculous pace. It was always trying to render and was never able to past 0%.

I saw this post when I was searching for a solution. this is what fixed it for me, I hope this helps!

Agree that it helps to stop background rendering. But I still have the problem when a project needs to be exported.

BruseX export takes 7 min. =:O

i'm on 10.4.4 on 10.14.3 and rendering/exporting is at snail's pace.....

I hope 10.14.4 really solves the problem as some of u beta users claim

Come on man. What’s your system? What’s the the computer? What’s the versions?

That just happened automatically when I dragged and dropped the clip into an event. It copied then started it's trans/analysis process. Is there a way to stop this from happening automatically?

Just tried to export via compressor (720p) and got this error:

One thing you did not mention doing is deleting FCP X preferences - hold down command and option while starting the application, and click Delete Preferences. This is usually the first thing to try.

If you are running an antivirus that usually has that kind of impact on professional software. Or maybe you have some other third party software that is causing trouble.

In these cases, the Etrecheck report is usually very helpful.

Try deleting preferences once more.

Also, try creating a new library - any difference?

Try running FCP X from a new admin user account - any difference?

I'd still like to see the rest of the report.

There may be system modifications (kernel extension, launch agents or daemons) that affect FCP X; or other applications in your login items.

Turning off background rendering worked for me - I was getting a 79 second response time for almost any action when it was turned on. It seemed that any action provoked the programme to render the entire movie again, or so it seemed. With background rendering turned off everyting seems to behave normally. Nick.

Are you trying to export? Do you need to render for playback? Don’t render unless you have to. You said it was a time lapse. Is it an image sequence made up of stills? Is it a single video file? Can you open it in the QT player and get the specs for the media? The computer has plenty of horsepower for most things, unless there’s a hardware problem.

Apr 7, 2019 2:56 PM in response to Tom Wolsky

Whoa. The Compressor step of adding the clip and exporting as ProRes seems to be working, no dropped frames, import into FCPX was like any other video clip.

I just hit render to see what happens and it rendered out the clip in the timeline in what seems to be a normal amount of time.

A little pain in the .... to do this but it is only the LRTimelapse clips that seem to be affected so it's truly a minor inconvenience. Thanks, Tom, this really helped me understand the process better.
