Plasma HTDV Comparison

“De-judder” is a feature becoming ubiquitous in HDTVs, yet no one has done a close video examination. It’s a 2D effect that artificially creates new frames out of existing ones (thus increasing your “FPS”). It works, it’s cool, but it’s not a miracle solution. The television demonstrated is an LG 42LH90 with “trumotion” “240hz” technology. Since Youtube does not support 60fps video, everything in the video is played at half speed (30fps) in order to demonstrate de-juddering. If you think about it, it seems like a creative extension of video compression technology, which breaks the picture into segments and predicts their motion path. De-judder probably does something similar in order to “invent” new frames, but it (understandably) seems selective about what areas of the picture it will attempt to “de-judder”. It works great for slow camera pans of course, where everything is moving across the screen in the same direction. Not so great for myriads of foreground and background objects moving in separate directions, or non-motion events like camera fades. It would be cool if it could be implemented in a GPU, so that elements can be processed separately and areas where the algorithm fails can be filled in with actual 3D rendering. It would be like modern adaptive anti-aliasing for motion. note: the interlace field bobbing is due to my camera, not the HDTV
