I nearly always edit in HD, but today was working with a small amount of 4K footage (25 clips - each roughly 20 secs in length).
My MacBook Pro went into meltdown and crashed loads of times (10+) before I gave up.
With this small amount of footage I had hoped to be able to edit and export natively using the internal drive.
The plan was to export the finished clips to the desktop for uploading via ftp and then save to an external hard drive. Once this has been done, the footage would be cleared from the hard drive as it won’t be needed again.
The laptop is a late 2013 retina model on High Sierra and FCP X 10.4 with 16gb of ram. The 500gb built in drive has more than 400gb of free space, so not clogged up at all.

I had hoped it would be able to cope. Initial editing and basic grading was ok but anything extra like noise reduction on a few clips was very, very slow though. Then when I tried to export individual clips to the desktop everything fell apart. I even slowed down making sure one clip had exported before starting another but it didn’t like this at times either.

The clips ranged between 100-140gb each, so again I thought it would have been able to handle this.

My question is: is there something wrong or is it the case that the laptop simply can’t handle 4K?

As I’ve always edited in HD previously, I’ve never used proxies before. Is this a way round the problem?
And, if so, what’s the best workflow?

Thanks

4K footage, depending on the codec it uses, can be very demanding on your computer. Two suggestions will really make a difference - 1. Create proxies of the footage for editing and be sure to switch back to Optimized/Original before exporting. 2. - Put your footage on a fast external drive (SSD would be great, but even a fast spinning external drive will make a difference). Even though your internal drive has plenty of free space, it is busy with managing the OS and asking it to also deliver your footage inside FCPX at the same time can be problematic. Put your media, and even the cache folder on the external drive, and then by using proxies you should be able to get the editing done.

If you don't have or want to purchase an external drive, at least creating proxies might help but likely wont be enough of a solution. You can try it to see the performance boost it gives you. Doing either by itself will help a bit, but doing both will be better.

Thanks for the info.
I’ll look to give that a try next time.
The codec is XAVC L which is said to be more intense for the processor.
That said, what’s the best thing to do with the footage that’s already on the timeline?
After exporting a few clips, the laptop is now crashing every time I try to export any more...

You can transcode the clips in the browser to proxy files and that will apply to those clips that are used in your current timeline. See this Apple document to further understand how to create, use and delete proxy files: support.apple.com/guide/final-cut-pro/cr...iles-verb8e5f6fd/mac

UPDATE: Also if you want to put the timeline clips on an external drive, either copy the entire library to an external drive, or create a new library on the external, create a new project and cut and paste the clips from the current project to the new one on the external drive.

That’s very helpful, many thanks.

Thanks for the link too. I’ll have a good look through and digest.

Some video codecs are harder to playback then others. MPEG 4 and AVC use H.264 but Intel's Quick Sync does not work with all version of H.264. That is why the video files might be difficult for FCPX to render and playback. The Red One R3d files are not that hard to playback and I wish the Red One Camera Company would license out their R3D video codec to Nikon, Canon, Sony and Panasonic. Having said that some of the new video codecs are hard for the Desktop PC and even the iMac Pro to playback and render.

Looks like I may have found the culprit as to why my MacBook Pro was crashing all the time.

I was given an sd card and asked to try to recover a few files on it after it had been formatted.
I looked online and downloaded Disk Drill as it was said to be safe for Mac.
This didn't really work, so I deleted it by dragging the it to the trashcan from applications.

But some smart monitoring icons were still showing at the top of the screen. So some online research showed that not everything is properly deleted by just dragging the app to the trash. So, I've now deleted the remaining files, the icons have gone and the laptop is no longer crashing!

I've now been able to edit and export the 4K clips. It's certainly not as quick as HD but it is working.

I was surprised that even with 16gb of ram the laptop kept crashing with a small amount of 4K footage.

Thanks for your help and I'll be looking into using proxies next time with 4K to hopefully speed things up.

Glad you got it working. Disk Drill may very well be the culprit, although it's an excellent tool and normally stable on the Mac. There has been an update to it (version 3.8.947) and among Catalina support it also provides a fix for random crashes and exceptions during disk scanning. This may be what you ran into. Best of luck.
