And though you get 24 discrete frames every second that way, the cadence is irregular.

To do this right, you have to have a variable frame rate like the HVX200, which this cam does not.
I'm confused about your methodology, but I won't debate it.

The Canon 24F streams I have (the true ones that weren't mislabeled), act identically to the 24fps streams I have from my own HD100. Same rendering of motion, everything.

Actually the HVX200 does *not* have variable frame rates. It has selectable frame rates. There is a big difference between variable and selectable. Hope this helps,

I doubt it's worth getting that technical Chris...

Even the Varicam has only frame rates between 1 and 60 in integer steps. If you want truly continuously variable, you have to consider an analog crank I guess.

all i can muster right now... is WOW!

Thanks my Ito&Chris for bringing us advanced footages before the cam's even released. This is incredible previlege to be a part of a group to see a dawn of a new revolution =).

i'm projecting some of those images on my 80" front screen projector and all the footages look awesome. i'm so gettin this.... in 5 years after price drops =). with all these new HDV cams coming out, we're coming upon an impasse. yesh it is still "video" but so was star wars episode ii&iii (so far the MOST financially successful "video" movies ever).

Has anyone else noticed that this camera seems to exhibit FAARRR less MPEG artifacting than the Sony? I mean, how is this possible?

Is it because the image is being compressed as a progressive image, and not interlaced? If you shoot in CF25 on the Z1U, does it produce less artifacting than in 60i?

I know that progessive frames like up a lot less storage (for the same quality) than interlaced frames. Each interlaced frame is really two frames in one (fields).

So for the same bit rates, progressive "frames" are much less artifact free then interlaced "fields".

Remember Kakus clips (except one) are also 24fps and not even 30fps, and so there is even more allocated data for each frame.

Personally I think that unless there is a lot of movement, at 24fps there will hardly be any noticable MPEG-2 baddies...
