.mov file import to iPhoto - how I did it
create album in iphoto
import .mov to library first rename it thus...img_1234.mov (numbers don't matter, avoid 0000)
add the .mov file to the new album
in itunes iphone sync options, in photos, find album and tick it AND on that page tick INCLUDE VIDEOS
in "summary", tick "include only ticked songs and videos" (dunno if this last particular step is really necessary but it doesn't hurt)
(disclosure: I actually sync very little media content with iphone, don't sync with icloud so this is a per-project thing and reset to original when accopmplished)
Sync phone
Now in iMovie, your clip will be pickable
I recommend you use it and output/save your complete iMovie asap
Go back to iTunes on Mac and de-check include videos and the album you checked in "photos"
Sync again, it will be gone from phone
One other little iMovie1.3 thing: if you are using any of the trailer formats - they require video, not stills, so plan ahead...have something you want to use in your trailer that acts like a still? video a few seconds of it with your phone (or import as above) first
