What they are all doing is the equivalent of "in-betweening" in animation, where the key frames are drawn by the source video and the computer interpolates the frames in between the key frames. If video frame 1 has a man with his hand at waist level and video frame 2 has the same man with his hand a little bit above waist level, then the video processor interpolates a frame between them with the man having his hand half way between the two positions, just as the frame sequence would have looked if it had been captured at 100 + frames-per-second rather than 50/60 fields-per-second. The catch is, the original video frames are still blurred compared to what a true 100 + Fps rate would look like. The in between frames are also synthetic, so there is no guarantee they would actually match what you would have seen at a true 100&nbsp;Hz + Fps. Basically, all this depends on how good the computer algorithms are at synthetic generation of frames. Despite these issues, the above techniques make a huge visible difference to blur and picture motion, a difference that can easily be noticed by anyone with such a television.{{Fact|date=January 2009}}
