DreamWorks CEO Jeffrey Katzenberg isn’t the only one who thinks poorly-executed conversions could kill 3D. Hiroshi Yoshioka, Sony’s executive deputy president and president of its consumer products and devices group, used his keynote address at the National Association of Broadcasters on Monday to issue a warning. “Poorly executed 3D is harmful, and it threatens its long-term success,” he said, according to The Hollywood Reporter. “Remember that 3D is a natural experience; it is how most of us see the world everyday. We must give consumers great 3D that looks natural and feels wonderful.” Of course, he went on to tout Sony’s comprehensive 3D technologies and to show the Resident Evil: Afterlife trailer, which boasts that it was “Filmed With The James Cameron/Vincent Pace Fusion Camera System”… “The World’s Most Advanced 3D Technology.”

The cynic in you could roll your eyes at the name-dropping, but when it comes to this technology, it does matter. Watch the trailer after the jump, and you see the difference between a movie that was shot as a 3D film and one that was converted after the fact. Anyone else tempted to see their first Resident Evil?
