Been using motion 4 a ton at the office and it has been slowing down my computer to a crawl and I am not sure why:


1. I have a pretty new mac with 12gb of RAM


2.  Even though I constantly need to jump into Bridge and Photoshop, I bite the bullet and shut them down to appease the computer gods. Still no luck.


Here are my other stats:


OS X: Version 10.8.2

Proc: 3.4 GHz i7

Mem: 12 GB 1333 MHz DDR3


Yeah, so should I be looking into nuclear power supply to get this program running correctly or ***?

    Motion is very GPU intensive. If your video card can't do heavy lifting, things are going to be slow.

    I made a SSD drive as my boot drive. It made a significant improvment. Also make sure you have a good video card.

    Your 2nd monitor is cutting the memory of the graphics card in half.  So I would unplug it and see if there is any improvement.


    12 to 16GB of ram is not a real big jump. But it should help a little bit.


    Every little bit here and there does add up!

    I don't know about older Macs... But on the mid-2001 i7 iMacs having more than one monitors hooked up won't affect the GPU. I have three monitors hooked up with no hit on the GPU.

    I have the 2 gig card.... Your graphic card is ok.

    It could be your second display.


    I did a test and added 5 particles playing at the same time. With three displays on and with only the iMac display on. No slow down... I put another 5 particles.... Slow down but not much.


    I distributed all 10 particles throughout the timeline, no slow down with one display or three displays.


    You have to remember when you add more (for example particles). You will always have a slowdown. Motion is like Flash. Motion has to display objects on the screen at retime, on the fly. For a particles it has to compute the object on the fly. (Flash has to do this inside a browser.)Screen Shot 2013-01-29 at 5.49.50 PM.png


    One last thing... make sure you have fixed resolution turn on for each layer group. This will make sure That each image... video... object and particle doesn't display beyond the bounding video box within Motion. If not set Motion still has to computer for these objects beyond the video bounding box.

    Lag time was significant for everything from motion boot up (3-4 mins) to basic x & y changes. It would constanly freeze up and be a pain in the ***.


    After the disconnection of the second monitor, motion started up so fast I didn't even see the title screen.

    Same here with three displays.
