Optical Flow (FCPX) Not Working in Mountain Lion

I recently upgraded to Mountain Lion was had to make some changes to an old video project. When I opened it up in OSX 10.8, all of the clips that I've slowed down using optical flow are not showing properly. They are using the frame blending option instead, even though "Optical Flow" is checked. I've tried deleting the analysis files in the Final Cut Events folder, trashing the preferences, duplicating the project, reinserting the clip and running optical flow again...NOTHING IS WORKING! The only thing that I can attribute it to is the upgrade from Lion to Mountain Lion. Please help!

Final Cut Pro X, OS X Mountain Lion, 2011 Macbook Pro

Very same issue here.

Quite special. In fact, if the clip is in H264, it won't do anything *at all*.

If the clip is "optimized" or pro-res 422 encoded, it will do frame blending instead of Optical Flow analysis....

Have you managed to find any workaround ? This is very strange, because it doesn't seems to be exactly the optical flow process but the import process : Clip imported BEFORE the Mountain Lion upgrade can be Optical Flow analysed without problems...

Same problem here. Could only overcome the problem by exporting clips from FCPX and making slomo in Motion with optical flow enabled. Quite annoying.

Same issue here... This was a big selling point for me. I like the optical flow and with this not working I am seriously thinking about switching to premier.
