PT9 on mac pro. Jerky QT video playback!?
Hey,
i was trying to run PT 9 on a Mac Pro Dual Core with Mac OS X 10.6 and I wasn't able to playback ANY QT (from DV PAL to H264) smooth. There was a jerky playback in every case. So I downgraded to PT 8 again, where it is possible to disable beam synch to get rid of this jerky playback. Only some H264 aren't playing smooth in this version. As I'm going to setup a new studio with PT9 in it, I REALLY need to have a stable video playback on my second DVI monitor. Is there any way to achieve this? best regards |

Hi Sawdust,
DV will definitely be the best way to go, H264 has quite a lot overhead so will eat in to your resources. Are the video files/session files stored on a secondary internal drive, your not pulling them from the system drive? |

I have the same issue. Had to go back to 8. I posted about this before with no resolution. I just need to find that thread... For me, 9 is just sluggish all around. Especially when drawing lots of automation. As music editor, I'm using a lot of mouse all the time. Those who track and use control surfaces don't seem to notice.

I have no problems with H.264 video in PT9. Just came off a movie dub were I had 160+ tracks of stems & H264 video in every session and it ran flawlessly w/PT9 even on my 2008 Macbook Pro w/Mbox2 Mini.
The only format I've had issue with is Apple Prores, Pro Tools will absolutely grind to a halt if you try and use quicktimes with that codec in your sessions. |

@KMcK:
Which version of OSX is running on your systems? Guess it has to do with that... |

I have been having this same issue on a 2.53GHz MacBook Pro with H264 video in PT 9.0.2, where in PT8 I had no issues at all. The only wildcard factor is the version of Pro Tools, so I have to think this is the root of the problem.
