When I change the value in the "Duration" field in the "Clip Adjustments" contextual menu and click "Done," sometimes iMovie automatically adjusts that value up or down by 0.1 seconds. I have not been able to figure out why it does this (and how it chooses when to do this), and I was hoping that someone here may know the answer. Thank you.

    iMovie has to round up or down to the nearest 10th of a second when you edit using seconds. You can get more accurate editing by going to iMovie/Preferences and checking "Display Time as hh:mm:ss:frames"

    This will let you edit to the nearest frame (e.g. 30 frames per second). Now if you are doing a 30fps project, you would enter 1.5 seconds as 1.15

    I too am fed up with this and last week visited my local applestore where they had not encountered this problem. When they checked on a Macbook it worked perfectly but when tried on an iMac the same problem that we have been having occured. Consequently they reported it to the Genius Bar and suggested I send a feedback to Apple which can be done by going into iMovie and then provide iMovie Feedback. If enough of us send this to Apple maybe they will do something about it. I would like to go back to iMovie 09 in iWorks but don't know how - if anyone knows can they please tell me.

    I and several other people have experienced this problem and posted about it. I thought it was simply something I had to cope with in iMovie 11. Now that I know it may be some kind of bug I will report the problem to Apple. I have figured out a way to work with the duration problem and so will stay with iMovie 11 because I like the audio flexibility it offers.

    I have the same problem: Does not hold typed clip duration. Always changes it after I click done. This is very frustrating, because I am building a TV Spot, and it has to be exactly 15 seconds long.

    I find I have better luck NOT using the HH:MM:SS method, but it's still frustrating.

    Do you see this while using transitions? A transition can be no longer than half the longetst clip to either side.

    Yes, it does occur while using transitions. But since a project has no set end time/duration, I would think (logically) that I can put in my two clips, at 7.5s each, and then put in a 5s transition, and have it "steal" 2.5s from each of the two clips, leaving me with my 15s TV spot, composed of three 5s clips (solid segment 1, transition, solid segment 2), right?

    No. If your two clips are 7.5 seconds, then the longest transition you can use is 3.75 seconds. This is because you may want to use a transition on a third, adjacent clip, which will also need up to 3.75 seconds.

    Yes, but that transition is borrowing time from the clips on either side of it, so it should be able to be up to half of the TOTAL of the two clips it is borrowing from — UNTIL another clip/transition is added. It shouldn't be "planning on the possibility" of a third adjacent clip — it should only make that calculation if the third clip is added.

    The two clips are 7.5 seconds each, giving a total of 15 seconds, so if the transition is allowed to borrow up to 3.75 seconds from each of these clips, it's total length ought to be able to be 7.5 seconds, before it does any recalculations.

    Perhaps I am just not understanding the logic here, but all I can say is that every version of iMovie prior to this has been more intuitive.

    when i adjusted the duration of the pictures and the transition,, why not the duration stick to the what i'd set,, its always change and i have to change it again and again but when i change it ,, its immediately change as it like and its become complicated,, it suppose to be easy anyway by using apple

    Transitions will always cause the Durations to be adjusted, that's always been the case with every version of iMovie since vers. 1.0. The video needs to 'sacrifice' some of those video frames to weave them together with video frames from the following video clip. But I agree it would be better to make it more predictable as to how it's going to sacrifice the video frames. One way to adjust this in iMovie '11 (I don't know about previous versions is to set the Overlap setting for transitions). Click on one of your transitions in the Project Browser then go to Clip Menu > Transition Overlap and choose whichever setting is not currently clicked and see how it reacts differently as you reset the Duration.Screen shot 2011-10-25 at 10.13.25 AM.png

    elikness is right on the money!  Just change the transition overlap setting, and it works like a charm.  Thank you all!
