On the new “MacVoices” (http://www.macvoices.com), Jeff Carlson has been spending lots of time with the new iMovie ’11, and has discovered a number of useful, cool and largely undocumented features.

He discusses the under-publicized return of the timeline (even if it isn’t called a timeline), the usefulness of Movie Trailer and other effects, and then dives into things you didn’t know, including rolling shutter fix, morse code in a theme, and several other minor but tasteful additions. iMovie ’11 still isn’t good with interlaced video; Carlson explains what that means to you and how to work around it, and why iMovie ’11 is finally almost like the long-dead iMovie HD.

“MacVoices” is an Internet show and podcast that delivers in-depth discussions with the most influential people in the Mac industry, as well as “the individuals who are out there making it happen on the front lines of the global Apple community,” according to host Chuck Joiner.
