Calidad video real o aplanada ¿como es eso?

Si el director quiere que veas algo más fluído, lo va a filmar a 60 o más cuadros por segundo para que lo veas fluído. Si el director no quiere que lo veas así, lo va a filmar para que no lo veas así. Querer de a webo verlo así, es como que te valga madres la experiencia que el director quiere que tú tengas.

¿Y puede el director filmarlo a 60 cps y luego yo verlo en mi casa a 60 cps ? creo que no

Los 24 cps son una restricción física, y obsoleta, Yo sé que puede grabar a otra velocidad mayor y luego yo verlo a 24cps para que la explosion en miniatura se vea mas real, pero hasta ahi.
La verdad he visto pantallas con este modo y me gusta bastante, parece una ventana y no una película, y me gusta sentir como si fuera realidad, mas que una pelicula.
Los links que les pongo al final hablan muy bien de este detalle, y resalto el siguiente comentario de uno de ellos:

"Actually, we've never seen 24 fps film quite this naked even in a commercial movie theater since the double shuttering action of the movie theater's projection system reduces the experience of judder and flicker. You can see some judder in the movie theater, but it is not as pronounced as it is on a digital home theater projector playing Blu-ray or HD DVD at 24p. "

Asi que los cines utilizan un "truco" para minimizar el efecto del movimiento borroso, ahora los proyectores y monitores presentan su propuesta.

Antes de los links, del review del Panasonic AE3000, explica como funciona este feature:
"Frame Creation. The AE3000 has a new feature which Panasonic calls Frame Creation. When activated, it allows the projector to evaluate movement between previous frames, generate an interpolated frame as a half-step, and insert it into the frame sequence. This is then played back at either 120 Hz or 96 Hz depending on if the source is 30, 60, or 24 fps. You have three choices-Off, Mode 1, or Mode 2. You can select "Off" if you want to disable the feature altogether. Mode 1 will use the prior two frames to do the interpolation, and Mode 2 will use the prior three frames.

The benefit of Frame Creation is that it renders a smoother, sharper image when the camera is panning, or when detailed subject matter is moving across the screen. The sharpening effect is more pronounced in Mode 2 than it is in Mode 1. Why did Panasonic give you the option to turn it on or off, you may wonder? The reason is that, though Frame Creation sharpens the image, it can make the image look to some viewers a bit less like natural film. Thus it can create an effect that some find objectionable. Therefore, you can experiment with it, and decide for yourself whether you want it off, or in Mode 1 or Mode 2.

When you have Frame Creation active it increases video processing time and thus delays delivery of the image to the screen. Even with Frame Creation off, you will typically see a slight video delay (most obvious in lip-synch). That delay becomes more noticeable in Mode 1, and more noticeable yet in Mode 2. If you are just getting started in home theater, keep in mind that all video display systems tend to manifest a bit of video delay that can produce lip-synch issues. That's because it takes more time to buffer and process a video stream than it does to get an audio signal to the speakers. The way you fix this is to use a corresponding audio delay feature that is built into most A/V receivers and external video processors. Or you can use something like the comprehensive but inexpensive Felston Audio Delay, which is what we use in our lab (see review). Audio delays will enable you to bring the sound and picture back into perfect synch, and they are an important part of your home theater set up. "
