More than a year has passed since Final Cut Pro’s last release, but the word is out that Apple has plans for a Spring announcement. Apple recently invited a small group of professional video editors to the Cupertino campus for a test run.

According to TechCrunch, early reports from those who demonstrated the new version suggest that the changes are “dramatic and ambitious” and may address concerns that Apple has turned its focus regarding video editing from the professional to the consumer space.

The new version of Final Cut Pro is said to be a “major overhaul” reports 9to5Mac, including a new user interface, 64-bit compatibility, and architectural enhancements.

TechCrunch reports Apple has plans to release the new version of FCP in Spring 2011, in a launch possibly coinciding with April’s NAB conference.

Film editor and sound designer Walter Murch wrote a letter to Roger Ebert in which he discusses the pitfalls of editing and viewing 3D movies.

Ebert notes that Murch is uniquely qualified to comment on 3D, considering he has received Academy Award nominations for films edited on four different systems, including: upright Moviola, KEM flatbed, Avid, and Final Cut Pro. He also edited the 3D “Captain Eo” in the 1980s and wrote “In the Blink of an Eye: A Perspective on Film Editing” in 1995.

In his letter, Murch addresses a number of compelling points such as the inherent darkness of the 3D image, the strobe effect of horizontal movement in 3D, and what he sees as problematic issues involving how our eyes and brain interpret convergence, focus, and immersion. Murch sums up his take on 3D as, “dark, small, stroby, headache inducing, alienating. And expensive. The question is: how long will it take people to realize and get fed up?”
