Currently Being ModeratedFeb 3, 2011 5:36 AM (in response to Leonard Johnson1)I've got this issue with my 14gig MacPro too, so this is not a Ram issue.
Most of the time I'm working with Quicktime DV on an external screen via firewire, and everything is ok :
no CPU overload, and no delay when switching from screen sets.
But, with Logic 64 Bit (as external video output is still not supported in 64bit…) I have to deal with the movie displayed on the screen and then :
- Looooooong delay to switch scrennsets
- some CPU overload when switching
I'm back few years ago…
For your issue, I'm suggesting changing mp4 to DV or Cine Jpeg witch are codec lighter on the CPU, or if you don't care about memory and 64bit considering a way to display your movie on an external TVDual 2Ghz G5/4 Gig Ram, Mac OS X (10.4.8)
Currently Being ModeratedFeb 3, 2011 6:21 AM (in response to Leonard Johnson1)I haven't tried freezing tracks. Although I know it's an option, I prefer to keep things fluid until I'm ready to commit. Every time you unfreeze a track to make a minor change, and re-freeze, it interrupts the workflow.
My config used to be 6 GB of RAM, and I recently upgraded to 12 GB (4 GB sticks x3), and then used the additional 1 GB sticks in the correct configuration utilizing DIMM slots 1-3, 5-7.Mac Pro 8-core, Mac OS X (10.6.6)
Currently Being ModeratedFeb 3, 2011 6:50 AM (in response to Pieca)I do use Logic in 64-bit mode, which is great for allowing for more instances of CPU-hog soft synths. However, I have noticed many 32-bit bridge crashes... and I've experienced the delay switching between screensets.
Are there any external display options that you would recommend to address this? I'll start requesting DV instead of .mp4 cuts, or convert it myself... but if there's an option to continue using 64-bit mode in Logic AND be able to not have CPU overloads because of video display issues, I'm in.Mac Pro 8-core, 15 GB RAM, Mac OS X (10.6.6)

I've been setting up 32 and 64 bit templates for film scoring. There are trade-offs with both. In 32-bit mode all of Logic's features work ( export audio to movie is a big one for me), access to 32-bit plug-ins, etc. In 64-bit mode you can open way more plugins but you lose some features and have to deal with the 32-bit bridge. It took me a while of tweaking to get my template so the processors don't spike.
Anyway, the slow screensets with movies in them has nothing to do with freezing tracks. I just tried it in an empty song and it still takes 5 seconds to switch. Also, the videos controls now must be adjusted through a preference panel instead of on the movie window.
I really hope the next update resolves these issues.

I was reading through some old discussions, and thought I would update my findings for other users reading these posts.
The problem is the H.264 format. Logic doesn't like playing back compressed video formats. Period. It really doesn't like it when you start asking Logic to use soft-synths and audio playback at the same time. It has nothing to do with the machine you're using. I have an 8-core Mac Pro running Snow Leopard on an SSD, with 32 GB of RAM.
Best solution for me has been to request a Quicktime video in either a DV or Photo JPEG codec, or even Apple ProRes. These are much larger files, but uncompressed or low compression... so Logic doesn't struggle with decompressing in compressed video in real-time playback. (Special thanks to Logic Pro Help user 'Ski' for putting me onto this solution). Ski doesn't recommend anything other than DV codec, but I have tested out Photo JPEG & Apple ProRes pretty vigourously, and have no complaints from Logic.
I'll need to read up a bit more on the the different formats, as each codec does something to the overall picture quality. This is important to keep in mind if you're going to be viewing the video with the Dir. or Prod. at your own place.
If the video editor can't accommodate your request, you can always venture out into DIY land... Quick Time Pro 7 allows you a TON of export options, so you can export the video yourself. However, you'll need to verify that everything lines up EXACTLY. You don't want to end up with an export error on your end, only to find out mid-scoring session that something is not lining up... or find that the burni-in timecode is not matching your session timeline. Proceed with extreme caution!!
Hope this helps someone.
