Moving projects between computers

[pepboy]

I have an entire project with slow motion effect. On my main computer I applied optical flow to my slowed-down footage. Took a long time to render, but am very happy with the results. The problem: When I duplicate my project, copy to another computer, and relink to event, it starts analyzing for optical flow all over again. Why is this? Wasn't this already done?

Exactly how are you copying your Project to another computer? Why do you have to relink anything?

I initially duplicated my project and related event to an external drive. When I connected the drive to another computer and opened FCPX, my project library window showed my external HD, and my computer HD. Working within the project library window, I dragged my project name listed on the external HD onto the name of my computer HD. I was then given several copy options. I chose "copy project and related events." I have been working back and forth between 2 computers and am now only "copying project" because my event was already copied and I haven't changed it. Each time I move my project, I need to relink it to the event (because it doesn't see it) by clicking "Modify Event References" in the inspector window. This has all worked flawlessly.
Here is the problem: I applied optical flow to my project on one computer and know that it was finished rendering. When I copied to other computer, it started "analyzing for optical flow" all over again. My frames seemed to retain the optical flow I had already completed, but couldn't get the background tasks to stop analyzing for optical flow. This went on for hours, it still had many clips to analyze so I decided to just quit FCPX. Now (the next day) I just decided to reopen that same project on the same computer, it "analyzed for optical flow" for about 30 seconds, and then was done! Everything seems fine now.
I am thinking something is very buggy with the program. Also found posting on another discussion board from someone who was not able to keep FCPX from continually "analyzing for optical flow."
Thanks-just starting out with FCPX (and haven't worked with FCP before).

Why not just keep it on the external drive and work off of it, rather than doing all of those copies?

If you quite out of FCP X before the analysis is completed, it will start over from scratch when you relaunch.

Thanks for the suggestions...I'll see if they help resolve my problem.

BTW, I'm seeing several folks with Optical Flow renders not happening. I'm concluding it's a bug in 10.0.1.

Thank you for the observation that Optical Flow seems buggy for other also.
