I beginning to wonder if Premiere CC has 1st release problems with any media other than what it directly creates or converts. Here’s why:
1) for a variety of reasons, I still own and shoot with a Z1U in HDV and just dump that to disk via the camcorder and FCP 7. Nearly every other clip I’ve imported into CC has some sort of digital artifacting, consistent pass after pass, in the same TC locations. These are clips which play fine in CS6, the finder, and of course FCP7.
2) any media that CC puts through an import routine, like AVCHD, plays fine.
3) I have an entire 8 minute program that’s nothing but AE6 anims in a Premiere CS6 project. Ditto the no problemo.
Bug? Graphics Acceleration? Won’t know till I hear back from AJA; 10.4.5 has an issue with HDMI playback in FCP 7. Their tech support is the best I’ve ever seen, and my direct contact there tells me they can see its a problem with their release and they’re working on a fix to 10.4.5. In the meantime, I’m back to 10.4.4 and CS6. I hope this info is useful to the community. I’ll be following the thread.
