I'm having some similar problems with poor video quality.
I just upgraded to iMovie 10 and have noticed a considerable drop in video quality, during the editing process, from the clips imported/transferred/updated into the iMovie 10 library from iMovie 11.
When I open the exact same clip in finder, QuickTime launches and presents me with a status bar indicating that a file conversion is in process. After the file finishes its conversion process and plays, the video quality looks fine. I've never seen this QuickTime status bar indicating a conversion is taking place until I updated to iMovie 10 and Mavericks. Additionally, I'm not even sure why any type of conversion would need to take place as the original clip is a .mov file.
Now to my two questions:
1. Has anybody else experienced this strange QuickTime file conversion process and if so why is it happening?
2. Has anybody else noticed this drop in video quality during the editing process in iMovie 10 and is this loss of quality going to remain when a project is finalized. I have t tried to do that yet?
I would just keep using iMovie 11 but apple in their infinite wisdom removed the ability to store clips/events/projects on a network drive. iMovie 10 doesn't support using a network drive either but I'm using a work around.

1. Quicktime player in Mavericks reads natively a smaller selection of video encoding formats than in Mountain Lion (.mov only indicates the wrapper) and now has to convert some of them before it can play them. Apple is moving away from older codecs see for example: https://discussions.apple.com/thread/5588482
2. Yes. While editing in iMovie 10 the playback in the small window is at low resolution - probably to limit processor load. (It is most noticable with stills which go noticably 'fuzzy' during playback but go sharp when playback is stopped.) In my experience this does not affect quality after sharing.

Thank you very much for your quick response. Everything that you said makes sense and I can now confirm, after having done it myself, that the drop in video quality does not, at least to my eyes, affect a shared project.
