Am I expecting too much of the new tracking facility?

Likely there’sa software conflict somewhere. Post an EtreCheck report  https://etrecheck.com  giving the application full disk access in System  Preferences. When it finishes the scan, click Share Report and choose "Copy Report.” Use the Additional Text button to paste the report into the reply.

I tried it and it worked perfectly. Then I tried again on the same project and it crashes the library every time now. It says it lost connection to the library and closed. But it's on the computer's primary drive, so that's a little strange.

I tried your video and I see that there is a difficulty where a person's foot steps in the background.

This seems to confuse the tracker.

The examples that Mark Spencer showed (thanks for posting the link, by the way - excellent video as usual from the RippleTraining guys!) worked beatifully.

I haven't yet had time to practice it.

Looks like I have the same setup you have and I can't even get the app to stay open after I click 'Analyze.' The entire thing just crashes.

Try resetting preferences. Hold option and command while launching FCP. It will open the default Untitled library. Open the library you were working on and see if the problem has been fixed.

I tried that. It worked once, then failed again. Could the library be bad? It had to be updated to work with the new update.

It's possible. Select everything in the timeline and copy, create a new library and a new project in this new library, then paste the project. See if it behaves any better.

I thought I might have solved it. I was tying to track a clip that had a custom transition on it already.

But the second one always crashes it.

Here's a screen recording of what's happening. https://vimeo.com/637299278

To create the second tracker I had to reset preferences on FCP and restart. Now even that doesn't work.

Weird, It's working perfectly well in other events in the same library. Must be something weird about that event.
