Hello, just for myself again clearly coming A film projector has a 2 bladed aperture, and a projected Picture 2 times? So 48 images per second? On DVDs, the film in half before? Therefore, it would be rubbish in 25P to rotate, because the picture more jerky then when I look at it as me in the movies, then yes because it did not with 24fps shown. Is it correct?
Thanks in advance!
Antwort von HeikoS:
It just jerky. Because the projected repeated the same movement phase has no effect on the perception of moving fluid (again, before someone wise ... would like: In a sample-and-hold display has impact, but exactly the other way than by Asker suspected, ie, the movement is less blurred, what the "24/25p-Geruckel" reintegrate should bring-> perception physiological Effect)

Yes, at least (72 possible), and with 48 B / s for each 1/96tel second.

No.. There are in effect 24 (NTSC) or 25 (PAL) frames (no line jumping).

No.. The increased frequency in the movies has something with the flicker to do in the movie occurs when the picture for exactly half of the time will not be shown, namely the mechanics during the next frame in the picture window is positioned. This is more comparable with a 100 Hz TV.
The Ruckeleindruck is exactly the same in movies and on DVD (eighth times that, then you will see it).
Whether you are in "p" or "i" films, you should decide for itself, by doing their own tests. You see the way, playing on modern equipment (computers, LCD, Plasma, Beamer) anyway everything as "p". If the material in the original "i" is s.sehen then "i" and "p" at a moderate or None from the same movement b) are in fast movements the motives sharper with "i" c) provides for very fast movements, the motion blur with "i" from unnatural.
Also: For "p" must be to create a natural impression of motion to have no other Shutterzeit select a 1 / 48 to 24p and 25p for 1/50tel.
