Hi everybody,


I just finished my little iMovie project. It contains a lot of clips which are corrected by iMovie's video stabilization, and it looks pretty nice and smooth in the preview window. Unfortunately, the exported video looks somehow shaky and jumpy (but only the corrected scenes). See an example here:


The source clips were recorded on a Panasonic HX-WA20 Camcorder in 1080-30p. I copied the files on my Mac and imported the clips in iMovie in 30fps NTSC. I tried to export it with QuickTime in nearby all possible configurations (and all possible frame rates), but the result was still the same. Do you have a hint on how I could solve this problem?


My Mac:

iMac, 2,8 GHz Inel Core 2 Duo


OSX 10.7.5 with iMovie '11 (9.0.8)

iMovie '11, Mac OS X (10.7.5)

    If you right-click on the Event name or on one of the Event clips, does it offer to Optimize the video? If so, optimize it and that will take care of hte problem.

    I really wish I knew as well. There's a lot of other topics just like this but no one has gotten an answer yet. :/

    I've given up on it too. I'm uploading all my videos to youtube, stabilizing them and then downloading them. That's the best video stabilizer i've seen

    For me, iMovie 11 (9.0.8) stabilizes my 1080p MP4 clips ONLY AFTER I have CULLED (deleted) some footage from each clip (pretty strange, I know).  I select some footage at the beginning or end of a clip, click delete key, then choose "Move Rejected Clips to Trash" from the File menu.  Whether I imported the clips with or without optimization (the latter creates larger AIC footage) seems irrelevant to my success.  By the way:  To date, my basic process set my new $450 Sonyt DSC-HX300 to shoot MP4 (instead of AVCHD) at 1440 x 1080 (only some cameras can do this; 1440 is not noticeably different than 1920 x 1080, but files are smaller).  AVCHD just required extra steps with Video Hub to work.  iMovie isn't recognizing my camera properly, so I use this kludge: Connect camera to a Mac with USB cable (the rest of this explanation is the kludge).  Find the footage in one of the mounted folders (ctrl-right-click to open them) and drag the clips to a non-iMovie folder, along with associated the THM files.  Open all the THM files in a text editor, bulk remove colons, and then - one THM file at a time - copy the date and paste to re-label the associated MP4 video clip putting AM or PM to replace the space between date and time.  Once named with their dates, I import (move) the files into iMovie, not bothering to optimize.  The only remaining problem is getting rid of the jello effect from the camera's rolling shutter.  iMovie 11 does not reduce my Sony's jello effect at all.  Didn't work for a semi-pro videocamera (HDV-V1U) that I used to use.
