I 'd like to share a few thoughts and speculations about what I have observed, read and discovered about Blu-ray and HD DVD juddering playback and 24p.
Some background:
http://en.wikipedia.org/wiki/Telecine- I have seen a Toshiba HD-DVD player playing the 2 fast 2 furious HD DVD movie with a very unpleasant amount of judder in a car chase scene.
- My PS3 produces unpleasant juddering pictures when playing the short movie "Ice" from the "Eight Below" Blu-ray.
- I have read that the Samsung and Panasonic Blu-ray player can have a lot of judder in some scenes
- I have read that the Samsung and Panasonic Blu-ray player produce more judder than the PS3. The PS3 has a very powerful multicore processor (Cell)
- Using the 1080/24p of a Sony BD player connected to a 24p projector does not seem to decrease judder http://www.ultimateavmag.com/hddiscplayers/1206sonybdps1/
- On a PS3, playback of a VC1 encoded movie runs smoother than with other codecs (German c'T magazine). VC1 decoding requires less computing power than the other codecs.
My conclusion: the major cause of juddering is the lack of computing power in the current players and not the 3:2 pulldown.
Speculations:
- The German magazine audiovision has tested a new Panasonic plasma 42 inches and found that it works quite well with a 1080/24p signal coming out of a powerful HT-PC. This is a secret that Panasonic does not want you to know because they don't have a 24p Blu-ray player.
- The PS3 will have 24p support when the new Sony LCD's with 24p will be available.
Final thought:
At the cinema, 24 frames per second is simply not fast enough. Can you imagine playing your favourite FPS game at only 24 FPS? This would make me sick. I hope that the movie industry will adopt a higher frame rate. 24 FPS was chosen in 1920!
