Trimension is a framerate enhancement software by Philips for video, primarily DVD.
The motion interpolation produced by Trimension is not entirely natural, but can be pleasing in many respects.
The software has been criticized for artificial look and has been said to make film seem like video, and potentially to degrade the movie-watching experience.
Framerate enhancement can provide an interesting benefit if it is performed after upscaling.
InterVideo includes Trimension as part of their WinDVD software beginning with version 6.
