Ynzerg Posted June 27, 2013 Share Posted June 27, 2013 This is driving me bananas, and I need help! I'm running Logic Pro 9.1.8 on my Early 2009 Mac Pro, 2.26 8-Core, 16 gigs of ram. My OS is running off of a small SSD (3 gb/s), and Logic pro is on the same SSD. The rest of my files are scattered about on various drives throughout my system, but everything is running off of internal drives, no externals. I'm doing a film score, and for some reason I cannot get this video file to run smoothly inside of logic. EVERY ACTION I perform in Logic has about a 1-2 second lag before the computer responds, and it is maddening. Even something as simple as moving midi data has a 1-2 lag before the computer responds. The video itself is running from a 6 gb/s SSD, which is connected to an internal RAID card; this gets me read speeds of about 495 mb/s on that particular drive. Should be PLENTY for a video file in Logic. The video file size—I had to split into chunks—is only 76 mb, (**76 mb off of a 6 gb/s SSD and its still chugging?!**) and a quicktime .mov file: very small! In spite of this, my computer still is incredibly laggy while doing things inside of Logic Pro, with video. Can anyone please recommend, or enlighten on what video codec to use in Logic and how to get it? I've read numerous, conflicting opinions online, and nothing has worked yet, so I'm at my wits end here. (The video file I was given is 960 x 540, h.264 Quicktime movie) Any advice would be greatly appreciated. Thanks so much. -R And yes, all of these slowdown symptoms are relieved by removing the video file. Link to comment Share on other sites More sharing options...
Eric Cardenas Posted June 27, 2013 Share Posted June 27, 2013 I'm not a movie guy but I believe DV or Pro Res will put less strain on the computer. Link to comment Share on other sites More sharing options...
efiebke Posted June 27, 2013 Share Posted June 27, 2013 It's my understanding that the h.264 video codec is a highly compressed one. Because of it being highly compressed, it seems that the CPU needs to work all the harder to manage the video with the film-composing process. As Eric Bradley mentioned, Logic Pro seems to work best with Apple's ProRes codec which is less compressed. Although I don't do heave-duty film-composing, I have success using ProRes (light) with Logic Pro. Also, making the film a bit smaller in visual size might be helpful too.

Ynzerg Posted June 28, 2013 Author Share Posted June 28, 2013 Thank you very much. I re-exported the video using "Compressor", and made it into a ProRes 422 video, instead of h.264. The size of my clip went up by a factor of 23, but Logic is running buttery smooth now. Thanks Link to comment Share on other sites More sharing options...

The size of my clip went up by a factor of 23, but Logic is running buttery smooth now. Thanks I tell you, it's such a great feeling to have the video and Logic Pro work "buttery smooth"! I seem to always have a very stable situation when doing the modest amount of video scoring with Logic Pro. I only mention this because we have the same type of Mac Pro. It's nice to see other people with Early 2009 Mac Pros experience stable situations. I plan on keeping mine for quite a while longer. Oh yea. Forgot to tell you that when you use the ProRes codec, the size of the video in terms of MBs or GBs will be MUCH larger! The video with this codec is not as compressed as you most probably know. Glad all is working well. Hope all continues to work well for you. Link to comment Share on other sites More sharing options...
