imovie export problem
I have captured a lengthy DV clip (1h) from a camcorder via firewire/thunderbold into imovie 10, did some editing and now like to export the movie to be shared on itunes/apple TV. however, when using the share function (to theater or itunes), the project shows up in the Theater section, but the caption below the movie icon shows permanently "creating movie" without making any progress. I can play back the movie in imovie either from the libary of the Theater, but can not get the file saved in itunes or exported into a external movie file. I tried various file/resolution options but the result is the same.
I am pretty new to the apple world and expected these media tasks to work better compared to PC based edditing, but am somewhat taken back.
I have a 27" imac, with 3.7 GHz i7, 16 GB RAM and 2TB free Fusion Drive space.
Please help.
