I am new to FCP, but noticed that the analysis of a magnetic mask suddenly slowed from rather fast to very slow. I have been looking for answers on the internet and found a few...
1: which media type I am using
2: the viewer is set on entire render view disabled
And that is as far as I got with answers, but still my analysis is very slow.
iMac 24″, macOS 15.6
Magnetic Mask should not "suddenly" become slow. However, it is sensitive to the clip duration. If you use it on a 60-second clip, then try it on a 15-minute clip, it may appear to suddenly become slow; however, analysis or export performance has always been dependent on the clip length, and it gets much slower on longer clips. In general, don't use it on a clip longer than 5 minutes. If you have a 30-minute instructional lecture and want to mask and adjust the speaker, blade the clip every 5 minutes and do those separately.
There may be possible interactions with other effects, but I don't remember those. I suggest you take a test clip, put that on a timeline with no other effects, use Magnetic Mask and check analysis and export performance. If that is also slow, give us the specifics. If it is fast, then incrementally add the effects used on your original timeline and see if it suddenly becomes slow with certain ones. State what those effects are.

Don't load media from the cloud. Save media locally →Does the same issue occur when you load that media?
Please give detailed information.
Mac Model
OS version
FCP version
type, frame size and duration of media
WHERE is the media stored
How much FREE space on both the system drive and the media drive
If I were to guess (and why would I not?), I'd say that maybe you are running low on free disk space...
You will need to give us as much detail about the media and the project as possible.
Are you now using different media?
Highlight the Library in the Browser.
Go to the Inspector.
At the top is "Storage Locations", click the Modify Settings button.
There you'll see what the Library is set to and where everything should be.
Imac Apple M4, 32 MB memory
macOS Sequoia 15,6,1
HD 2T, 1T available
FCP 11.2
Most of the media comes from the photo album (iCloud?)
About the media drive, I don't know. Can I determine in FCP where to store and what would be the best option?
Yes, I am. DJI drone, DJI Pocket, Iphone
Magnetic Mask analysis in FCP very slow on my Mac (M4)
