Stephen - I think we're deeply into the area of semantics - you know what Piotr meant.

[QUOTE=Stephen van Vuuren]
(1) 24p - This actually refers to two different qualities. One, the image is captured and recorded as single image moment in time - like a still or motion picture camera. Second, 24 of of these single image moments are captured each second. 24p is actually more correctly called 24 fps progressive. Stephen, thank you for the clarity and conciseness of your description of frame modes -- the best I've come accross so far. So, how would you describe Canon's 24F in the XH cameras? |

I'm only being picky here as there is much confusion over all things interlaced and progressive. |

In some ways it's a very advanced frame movie mode but giving you 24 fps instead 30fps and seems to a better job of saving resolution than frame movie mode did. True progressive is still superior to 24F mode but due to some fancy engineering, you get shutter speeds under 1/60th with 24F which you would not get shooting 60i and deinterlacing in post. So 24F gets my vote, especially when you factor in not having to render and tweak in post. |

The point of the story -- which you missed -- was that one would expect/hope that 1080p displays would do better in 2006 than 2005 HDTVs did. They didn't -- they failed. Bringing H rez. in proves nothing about V. rez. HDV is an anamorphic format and displays correctly on any ATSC TV. Unless, as pointed out in the story, the pulldown cadence is not picked up properly. If its not picked-up, you lose H. rez. So shooting 24p has its own issues. The fact that folks don't notice the 50% means nothing. After all, the majority of HDTVs fail yet millions don't notice because they have nothing to compare it with. I would never trust anyone's eyes when there is an objective test. And, two years running the sets failing are greater than 50%. So maybe YOU got lucky. The statistically majority of folks watching interlace programming will not. Thus, the vertical resolution measures for interlace camera -- is for the majority of viewers cut in half. Now, compare that number to 720p cameras. That's the facts of interlace. |

"Rendering and teaking" has nothing to do with 24F verses 24p. Both in the timeline are 24fps. |

Here are my own non-technical comments to the original poster of this thread. I hope he finds it refreshing: 1) regardless of the technology behind the display you or your viewers have, if Interlace doesn't look and feel like "live-camera-you-are-there" Interlace, then the set-up is wrong. 2) Interlace is not a error. It is a specific "live-feel" format for creating a certain texture for the viewer. I ALWAYS prefer my sports and news in interlace. Interlace actually helps convey a sense of immediacy. Even docs like "Elsewhere" on the Voom HD channel, Equator, have a "looking through a window quality because of interlace. Don't let anyone here tell you that Interlace is "bad". High Def resolution Interlace can be beautiful. 3) Progressive is awesome because it really begins to relate to the feeling of film. Features feel more like a narrative story you can lose yourself in and docs can feel like a part of the historical record rather than just a news piece. Progressive feels important and "long-term". On lower budget equipment Progressive can feel more appealing and luxurious. I hope these opinion are helpful in your decision making. -Christopher |

Motion progressive images are ALWAYS more pleasing to the eye then the equivalent interlaced images, but make sure to compare the same frame rate. Compare 60i to 60p or 50i to 50p. 60i to 24p is not a very informative comparison for seeing the effects of interlacing since the frame rates are so different. |

Now the V1 24p, 25p, and 50p are still carried by interlace, so it can be screwed-up by one's display. But, the internals suggest are 60p and this suggests that on a NON tape media -- Sony is close to 1080/60p. |
