This just started happening. Even with older projects. The only way I can get fluid playback is if I turn all audio off. Even on a simple 1V + 2A that's a minute long. Footage was shot using a Sony Nex 5r transcoded to ProRes422HQ.
ProRes 422 HQ
Data rate is approx 52 MB/sec
Stereo Playback L+R
Audio Playback Quality - Low (faster)
This is being cut on my MBP 4,1 10.6.8, 4GB RAM, FCP7 is current, with a G-Speed RAID 4TB via FW800 and have never had an issue like this! If more info is needed, I'll be happy to oblige.
Thoughts greatly appreciated (aside from "get FCPX")!
But just playing low bit rate audio (86k/sec) causes dropped frame warning. Even with Safe RT, quarter res playback, etc and no video imported!
Just why all of a sudden? For 5 years, I've never had an issue like this with FCP. Plus, nothing new has been installed that would cause an audio issue. My Premier Pro CS5 projects (same footage and audio) play fine off the RAID.
Maybe a total wipe and reinstall of Studio will help!?
