Tu parles de ça Hervé :
My iMac is about 18 months old and it seems to be able to handle 1080/50p quite well. However, iMovie '09 can't import the AVCHD files directly from the cam. A workaround has been developed by Alan Somers who has created a very useful application called "Rewrap2M4V":
http://discussions.apple.com/thread.jspa?threadID=2380085&ts tart=0
After copying the AVCHD folder to the Mac, the mts files in the BDVM > STREAM folder are simply dropped onto Rewrap42V and they are virtually instantly rewrapped into MP4 files without any transcoding being required. The original mts files or the resulting rewrapped MP4 files can be viewed on the Mac very smoothly without any stuttering by using a free application called Movist:
http://mac.softpedia.com/get/Video/Movist.shtml On my Mac I find that Movist provides smoother playing than does Quicktime Player 10.0 or VLC player.
The rewrapped MP4 files can be imported directly into iMovie. However, when initially set up for PAL or NTSC, when iMovie 09 v. 8.0.6 imports files, even when Full - Original Size is chosen in the Optimize Video pulldown menu, a conversion to Apple Intermediate Codec (AIC) takes place within iMovie for editing, and this creates a video that is not 50p but is actually 25p (or 30p for NSTC). This can be verified by using the maximum Frames per thumbnail setting of 1/2 sec, and then moving the cursor through the movie one frame at a time. Despite this, the Export using Quicktime options do include 50p (or 60p). Hence the Quicktime movie that results after exporting by choosing the 50p option is a .mov file that appears to be 1080/50p, and has a 50p frame rate, but is actually 25p with every frame duplicated.
To overcome this problem there is a workaround that has been discussed on the Apple forums, which is to use a free software program called PlistEditPro.
This can be downloaded from:
http://www.fatcatsoftware.com/plisteditpro/
This enables access to the normally hidden iMovie preference file which sets the frame rate for the AIC conversion to be changed from 25p (or 30p NSTC) to 50p (or 60p NSTC).
After doing this change iMovie will import and automatically convert 1080/50p video clips in the form of the above rewrapped .mov files to 50p AIC for editing. Unlike interlaced clips, there is no danger of losing resolution when using any iMovie Effects during the editing process, and the 1080/50p is preserved throughout.

J'ai donc téléchargé le soft et ouvert les préférences de Imovie 08 avec et voilà le résultat:
Il suffirait donc de changer 30 par 60 et le tour serait joué ?
En plus j'ai souvent entendu parlé de 49.95 fps au lieu de 50 et de 29.95 au lieu de 30 il y aurait quelque chose à faire pour ça aussi ?
