hi
I have some of the same problem but in AF CS4.
Its a HD clip with wire removal, and when I render the clip it turns either black or in my case blue.
Its like the red color is gone.
I have rendered the clip before but on a nother pc than the one Im working with now. also had one clip that fail and turned black then, but the problem mysteriously disappered by it self.
now when I try to render they all turn blue.
and I cant have a blue bachelor video:)
