Green 2K Proxy files in FCP

[re_son]

I'm currently cutting something shot at 2K.
Within the folder structure I have 4 proxy files (the largest of which is 2K), they all work fine in Quick Time, but the largest file doesn't work in FCP.
When I bring the 2K proxy into FCP it goes green!

Does anyone know if you shoot at 2K whether you can use the 2K proxy to cut with? Has anyone else experienced this?

I'm hoping it's not corrupt media...

probably its _F.mov , its not yet supported in FCP

Yea, that's right it is "_F.mov". I didn't know it wasn't supported in FCP yet, really pleased to hear that though, was worried about corrupt data.

Thanks for that!
