Hey guys!

I just got my new Macbook Pro 16", 2.6 6-core i7. 32GB RAM & 8GB GPU.

I'm sitting in FCPX and trying to edit a simpel single file.

Suddenly this "Frame dropping" appears.. What is it and what do I do about it?

At its simplest, it means that the resources available to edit the clip/timeline can't keep up. So frames drop. There can be a lot of reasons - others apps taking resources, the video format you're working with, and so on.

Can you provide a bit more on what you're doing?

Thanks for taking your time.

So I'm working with one clip on 28 minutes and it's only 65MB. It's an mp4 file from a screen recording. I'm only doing jump cuts..

Media was set to "Optimized/original" and quality was set to "better performence".

I had no other software running in the background.


I was pretty sure that I should be able to do that without any concern with my new machine. I mean, I didn't experience this on my old Macbook Pro 13" from 2014 with 8GB ram and 1,5GB GPU.. Hah..

If the new machine is running a more recent OS than your MacBook, some of the underlying codec/video transcode apps were dropped in newer OSs. Or perhaps you had the notifications turned off?

You can turn the warning off if you don't want to be bothered by it. It only affects playback while editing, the shared video should be fine.

Before getting my iMac Pro, I'd often convert video to ProRes before editing, as it seemed that FCPX used a lot of resources to process through any little video defect.

I have been running Catalina on both the old and my new Macbook Pro and the same for the nontifications.

But with that being said: Isn't it wired that my new powerfull Machine is dropping frames?

If you’re still interested in an answer, can you post details about the file? If it’s a screen recording, is it from your new machine? I’ve had problems with recorded chats, for example, that had wacky frame rates. FCP X was usually pretty good at handling them, but maybe yours is particularly troublesome. Converting to another format is a good idea, one that FCP can handle better.

Hello mate

Thank you so much for taking your time!

As you can see it's just a screen recording from Zoom, but it is recorded on an older PC. So no, its not from my new machine.

At some point I also just need to know that there is nothing wrong with my new powerful Macbook Pro?

Thanks!

Yeah, it’s a highly compressed mp4, no doubt with a variable frame rate. FCP is probably just getting confused because it’s looking for constant frames based on your timeline, like 24p or 60p. I wouldn’t worry about it. If you keep seeing this error with camera-originated clips, it could signal a problem, but if it’s raw from zoom, you could transcode it to a standard constant frame rate clip, it should be fine. If it’s not doing this with other clips, I don’t think there’s any problem with your computer.

Thank you mate. It makes sense! - I don't see this error on anything else actually so, ye, it should be fine!

Do you know the easiest way to trancode the clip into a stabil frame rate?

You could drop it into a timeline and export it from there, final cut should conform it to the timeline frame rate, and dropped frames shouldn’t be an issue then. Alternatively, you could try handbrake or another compression utility. Just be sure to make the output settings what your eventual timeline will be: if you’re editing 1080p/24, make sure that’s the output setting.
