I see the same problem with my Sony NEX-5N. Footage comes in and gets converted to MOV from MTS but the video is horribly interlaced when playing through iPhoto. Strangly though if I reveal the imported file through iPhoto and play that in MPlayerX it looks fine, its only when playing through iPhoto it has the interlaced lines!!

More than half a year has passed, anyone with new, fresh ideas?

I couldn't find anything to fix it. I ended up not bothering with iPhoto for my AVCHD imports and instead just copied the files from my camera to a folder in my Movies area and I edit them with Adobe Premiere Elements 11. That way I don't have to import them with iMovie and have them blow up huge in size, I can just drag the file in, edit and export in minutes.
If I want a quick view of the AVCHD clip I use either MPlayerX or VLC.
Wish Apple would fix this. Every person I know who has a Mac and an AVCHD camera has the same issue.

Suggest to Apple - iPhoto menu ==> provide iphoto feedback

I did last year, but I don't expect any response

Chances may not be good (or may be) but for sure they are better when you tell Apple than they are when you tell other users here - Apple can choose to change it - even if we 100% agreed that it is critical and the most important thing n the world no one here can change anything

I know these are old posts but you get the same problem when viewing the videos from imovie in the events folder. The problem is Quicktime player. If there were a way to uninstall the application then the files will be achd and not .mov as quicktime sort of compresses them into .mov which causes the interlacing. If you were to uninstall it and then play the file with a diffrent player there should'nt be any interlacing. (If you try this make sure you move the iphoto videos) Iphoto uses quicktime... So until Apple updates quicktime player so it 'FULLY" supports AVCHD then we are always going to have this problem.

You can set a different player to open and play AVCHD movie files as follows:
1 - select an AVCHD movie file and type Command + i to bring up its Info window.
2 - go to the Open With menu and select the player you want to use.
3 - click, on the Apply to All button.
It won't work from within iPhoto but it will open any AVCHD movie file you click on in the Finder with your player of choice.

I was surprised to find that the playback in iPhoto makes the video show lines/waves from the interlaced video when there's ”much movement”, but if I in iPhoto reveal the original and open it in QuickTime Player it playbacks fine!
I also get the same kind of ”bad” playback if use QuickLook on the movie in the Finder.
What gives? Why does QuickTime Player.app handle the playback different than iPhoto and QuickLook?

QuickTime has a built-in de-interlacer. The player inside iPhoto seems more primitive. My video camera produces 1080i 29.97fps video or 1080i 60 fields per second.
Interlaced video is a pain on computers and I wish camera makers would stop using it. But it does result in smaller file sizes and for most home movie situations it's probably fine.
I've had to get very familiar with interlaced video, de-interlacing, de-combing, etc. Next camera will be 1080p for sure, just to eliminate the hassle. It will be worth the extra hard drive space just avoid all the problems with interlaced video on a computer screen.
