Does anyone know if "Cinematic Mode" is the same as "Cineframe 25"??????

I think, all Sony HD-s have Cineframe. So i'm pretty sure this is it.

Are you saying that Cineframe25 is bad? I was under the impression that is was very good from the footage i've seen.

Donnie,

There are plenty of reasons for and against Cineframe mode. Obviously Franks opinion of it is low, but it's merely an opinion and nothing more. If you like the look of Cineframe25 use it. I personally think it is the only Cineframe mode worth a damn. I like the look of it. The only reason I can think of not to use it would be if you plan on doing a film out, because of the drop in reolution. Even then it wouldn't be terrible I'd imagine. The resolution would still be higher than that of a DVX100, and plenty of films have been shot with that.

The bottomline is this, if you like the look it gives you, use it.

Well you shouldn't transfer interlaced footage to film so the resolution must be lost at some point.

CF24 is the one that truly sucks (makes image jittery etc.) CF25 seems to be just a good deinterlace done in camera. What I have heard is that at least with the HC1 all manual control is disabled while in CF mode, that's not too nice.

Maybe there is difference between cf24 & cf25 but as much i know. CF generally uses very absurd algoritm for getting "progressive" image. It means if You switch on CF then You get just one field from interlaced frame. CF multiples the same field to another as well. So You got reduced vertical resolution.

For the most part that sounds about right. I don't even think Cineframe is actual progressive. Sony is definitely using frame blending to achieve it's cine-look which does reduce resolution. However the framerate cadence for Cineframe25 looks virtually identical to 25p (to my eyes). Converting 25 (50i/25fps) interlaced frames to 25p is easier than converting 30 (60i/29.97 fps) interlaced frames to 24p. Thats why NTSC based Cineframe24 looks a bit spotty.

a) sometimes is very important to get progressive image for chroma keying. It's just painful process asnd nasty result at lower res.
b) in case You wont to achieve better framing. You have to use crop. Now You got twice reduced image in master.
c) Why buy HD when SD is ok?
