Moving library and missing video

I am working on this project on my MBP. All media is imported into the library.
Today I trying to work on the project on my new Mac Pro.
Everything work fine...onlt some clips on one angle are missing and I get that red screen. I double clip the milticam to go to multicam edit and the clip show like it's there, but when I skim the clip I get the red screen.
If I right clip to open in timeline the clip is there and plays fine. Switch back to angle edit and it's bad agin.
(Note that the clip shows the it's content visually but it won't skim the video).
Please advise

Here is more info on the issue:

You can see in this image, when I skim the angle clip in the multi cam edit the video does not play...,



Rightclick opn the angle clip and OPEN IN TIMELINE, the video play just fine!



Choosing to reveal the clip in the browser, skimming the clip in the browser plays fine too.



Please advise as I am stuck with this problem and it is ruining my edit.
Note that if I open this same project from the same HD on my Mac Book Pro everything is perfectly ok.

Thanks in advance

I'd start by deleting render files (File->Delete * Generated Files) (where * stands for Library, Project or... depending on what is selected).

Also, for good measure, delete prefences (start the application while holding down the command and option keys and confirm)

lichinho,
I have fixed it by disabling STABILISATION on that clip.
I don't understand...

Perhaps the process was interrupted before stabilization could complete, or for some reason the stabilized clip rendered improperly. Try, as suggested, to delete the render files and reapply stabilization to that same clip. Be sure to let it complete analyzing and then render it. See if it then works.

It might be it dgwvideo. it was taking so long to analyse and render that I might have interrupted it.
will try again, thank you.
