Timwillows Level 1 Level 1 (5 points)
imovie has recently got really slow, about 1 minute to load with events and projects loading one by one in slow time. Also slow to open a project with an additional wait with "loading project' while it actually opens.
I dont have too many projects, 5 in total, though there is a lot of source video in events - but no more than there was a couple of weeks ago when t was working nice and fast. 4GB RAM and a few hundres GB of hard disk space available.
Any ideas?

iMac 24", Mac OS X (10.6.5)

    Also having problems. Analyzing events for people has slowed imovie down to point where it's unusable. Event is held on separate drive to mac connected by firewire.

    Have gone back in project using Time Machine to before "Analyze for People" was performed. iMovie going fast enough now. Won't use "Analyze for People" again until an update released. BTW: another thread on similar topic is titled "excrutiatingly slow"
  • Timwillows Level 1 Level 1 (5 points)
    Thanks for that. I dont think I have ever analysed for people, how would I know?

    You're welcome, Tim.

    Basic info on "analyse for people":

    If I run in to problems with iMovie slowing down again I'll use Time Machine to go back to the point it was working properly.

    Good luck.

    I have this same issue. Every time I do anything, like cut a picture out it loads for 20-30 seconds. This is making things go excruciatingly slow. Is there anything that can be done? This is just about unusable, I never had this issue with the previous version of iMovie.

    Hi,

     

    I'm having the same problems.  iMovie suddenly runs extremely slow.  It's actually unusable.

    every click with the mouse turns into a one minute freeze.

    Don't have this problem with any other app, my iMac runs smooth.

     

    does anyone knows a fix?

    Had same problem for the last few weeks. It took ages (around a minute or so) to open iMovie and load all the projects. Interestingly another affected application was Word, which also was very slow to open.

     

    I realised the problem stared around the same time I installed Windows on a Boot Camp partition. I removed it, rebooted computer, and iMovie loads within around 30 seconds. Word also speed up.

     

    Can't explain it, but glad it's sorted Wasn't using Windows anyway

    IMOVIE 11 Brings tears to my face literally...I have a 2008 Mac Pro with 24GB Ram 4 Tb HD which i use to store video if i could. My computer software is all up to date with the latest updates and i think that's were the problem began ?. I now run Motion 5 64 bit and imovie runs in 32 bit, i am wondering when they will bring out an update to let IMOVIE 11 Run in 64 Bit Mode so it can take full advantage of the 8 cores ex...as it stands it only uses a fraction and runs like a SNAIL, i can't have fun with programs that one day decide to drag out my experience which was suppose to be a Happy One. This would be ok if it's just me but a lot of people are having the same problem, APPLE PLEASE SORT OUT THIS DEFECT.

  • DanInDub Level 3 Level 3 (640 points)

    I don't think you understand what 64-bit means.

     

    32-bit application can use 8 cores just as well as 64-bit. The difference is in amount of memory that can be addressed (used). 64-bit would be required to benefit from amount of memory that you have.

     

    Notice however iMovie is not targeted at Pros with 24 GB of RAM. In fact, I'm pretty certain it's not going to be any faster, as it appears it's not pefroming any video-cashing that could benefit from additional memory (I could be wrong, this is just a general observation). Probably isn't optimized to use more than 4 cores.

     

    ALso, you did not mention what sort of video you are working with (full HD?) on 2008 processor, which probably isn't best either.

    Hey Thanks for your reply DaninDub, I was at the apple store today with with the box while they ran test & Test, one of the chaps that i was talking to said it's only using a fraction of what i had to provide in the box, Motion 5 was taking advantage of all 8 cores but i'm sure he said IMOVIE was not, the funny thing is..IMOVIE use to run like lightning when first installed 2011 edition  ? and that was working with HD 1920 X 1080 Film, it had no problem at all but gradually got sicker and so on, and now is slow as, i can only think it's from the updates.

    I just bought a brand new 2.7 with 500Gb to substitute my dual processor windows vaio notebook. At the beggining imovie 11 worked fine, but when the movie passed 20 minutes long, imovie 11 performance started to go down quickly. It´s doing so bad now, that I´m thinking to return to my old notebook with my Vegas software!! I really don´t know what to do either.
