Is Frame Interpolation Important?
Is Frame Interpolation Important for You?
Well, only you can decide that. Personally, I am distracted by motion judder when I see it on the large screen. I was never bothered by it when watching a 42" plasma TV because the image was too small and the artifacts were less obvious. But at 120", the viewing experience is more immersive, and motion instability can be quite annoying. I'd rather have those artifacts gone if I have the option. So I am elated that vendors are now beginning to tackle this problem.
However, having said that, I should also say that motion judder is not a problem in all films. For example, the new release of Thunderball in Blu-ray has very little judder. The script is bad and the acting is worse, but at least the cinematographer knew what he was doing. In this film there is very little camera panning, and when the camera does pan, it almost always moves slowly enough to avoid the introduction of judder. You can watch this film in its entirety in native 24p and see almost no judder at all, which is rather remarkable. If you happen to be watching movies that were filmed in this manner, frame interpolation has no benefit.
On the other hand, the new Casino Royale Blu-ray, while it is a much better movie, is not nearly as successful in this particular regard. Moderate speed camera panning is rather frequent in this film, so you see a lot more judder. But it's great for us. We use a number of scenes in this film to exercise the various frame interpolation systems on the projectors that have come out so far.
And by the way, contrary to what one might assume, motion judder is not a problem that is limited to action movies. We've mentioned the film Swimming Pool on occasion before. This is an example of a very slow paced movie with no action whatsoever, and yet it is full of motion judder. It is not the amount of action in a film that produces motion artifacts, but rather the way the cinematographer handles the camera. So don't think that just because you are not watching stuff like 2 Fast 2 Furious that you won't be bothered by motion judder.
In the end, frame interpolation can be used with different types of film and video source material with great success. Sometimes it isn't necessary, and sometimes it helps enormously. Some frame interpolation systems are clearly more comprehensive than others, so as they say, your results may vary. We are extremely supportive of this new enhancement to video processing. Our hats are off to Panasonic in particular for showing how powerful the technology can be. We hope all vendors will give serious consideration to including it in their next generation video projectors.
