iMove 11 will analyse the clip but when you place the clips in the project there is no actual stabilisation going on. It's ticked in the menu but there is no control over the percentage. Stabilization works fine with clips from other MP4 cameras such as the Nokia N8.

Any ideas...

    It may be a bug with this version. I've see this on a couple of my clips as well. It seems inconsistent.

    After analyzing a clip for stabilization, simply add the clip to your project.
    Double click the Video Clip to bring up the "Clip Adjustments"

    Use the following to adjust the level of stabilization:

    Stabilization: Smooth Clip Motion, check box
    *Maximum Zoom*: Slider Percentage

    Although, if your clip has a red wavy line going across it, it probably means it can't stabilize the clip.

    Clip stabilisation isn't working at all. I have tried it with a small iPhone project, I followed the instructions and I even found that w i t h o u t stabilisation the result is a lot smoother. The feature was one of the greatest inventions in iPhoto 9! A pity that it's gone ...

    Apple, please correct the code within reasonable time! Thank You!

    Give this a try:

    _ Shoot a new 10 second video clip with your iPhone4, that contains a little bit of up & down motion
    _ Launch iMovie '11
    _ Connect your iPhone4 to the Mac
    _ Import the new clip you just recorded to a "New Event" using the following settings:
    . . . . . . . . . Check ON : After import analyze for: Stabilization
    . . . . . . . . . Check OFF: Optimize video
    _ After importing the clip, create a new project.
    _ Add the clip to the project and check if it's stabilized.
    _ Compare the playback from the Project, to the playback from the Event.

    Is the Video clip in the Project stabilized?

    Sorry, Your proposed procedure didn't change anything!
    The only minimal shake (I held the iPhone during 3 scenes against a pillar in the audience) is still here.
    The framerate is indicated as 27, I got the chance to reduce it do proposed (iMovie 11) 24 fps; also this didn't help.
    Have You made Tests with a "real" camera or video?

    Thanks for Your help,
    kind regards

    I tried two similar clips from my iPhone 4. One worked for image stabilization and gave me the zoom slider. One did not. Ironically, turning the rolling shutter reduction on for either actually made it WORSE. Anyone else experience this?

    I'm not seeing that it makes any difference. I'm shooting with a Canon 7D.

    It may just be me, but it seems the entire image shakes around the center, and especially at the edges with stabilization turned on, which I don't believe I saw in iMovie 09. The rolling shutter reduction does not seem to have an effect.

    I have tried my Panasonic FZ100 photo-camera, which does besides excellent photos also 720p and 1080i video. I tried the "long" tele at 600 mm in 720p mode. The camera itself is stabilized, but at 600 mm it shakes anyway without a solid tripod. This minimal shake I couldn't prohibit was - according to my impression - after stabilisation in iMovie11 even worse than in the original video!

    But - and this is also surprising for me - on the MacBook Pro of my girlfriend (with iMovie9!) I got the same bad result. So I ask myself: has anything changed o u t s i d e of iMovie, that has an effect on the stabilisation algorithm?

    Sometimes things seem unexplainable to me ...

    If anyone discounts your post because you're doing 600mm, the tests I've been playing around with were shot at 15-22mm!

    Sounds like your processed video looks worse as well. I've got one machine left with iMovie 09. I'll try it there.

    I think I've figured out my problem with this. In my case the video import is 1080p and now with iMovie 11 and output to my new Apple TV, my target output size is 1080 as well. Hence there is no 'extra' resolution which to clip from, so that although I can enable clipping, there is no slider control visible and 100% is listed as the maximum zoom.

    The problem with video stabilization on the iPhone 4HD camera is that, it suffers of what it calls a rolling shutter effect. All CMOS based camera do this including the top of the line Canon 5D MK II.

    The video stabilization software has to contend with various motion shakes plus the jello effect of the rolling shutter making it difficult to apply compensation especially to a HD footage. If it were a SD footage, then a mid-end Mac can do it. For a proper HD footage compensation, the amount of memory required plus the processing power of the Mac is beyond the reach of most people.

    Your best bet is to reduce as much rolling shutter effect as you can because that can cause shakiness on your footage.

    Hi everyone,

    I have the same problem mentioned above. Stabilization can not be applied correctly to all my video clips from iphone 4, although I've installed iMovie 9.0.2.
    Actually, the problem ought to be solved since Version 9.0.1 according to Apple. But it seems, that it still does not work. Has anybody the same problem?

    I've thought about buying "movie stiller" for iphone in order to stabilize the iphone video clips, but I still hope for the rescuing bugfix of iMovie...

    Absolutely right, very little iMovie can do to compensate for a really severe rolling shutter ("jello") effect.
