maybe im just extreamly tired and sick of sitting behind a desk.. but im confused.. do u have to shoot 4k in order to achieve a s35 frame? 2k only shoots s16 frame?
or does that even matter..

The only way to get the exact s35 FOV with a given focal lenght is to shoot 4.5k. 4k is normal 35mm in 1:1.77 aspect ratio.
In the end it doesnt really matter that much. You still get 9 million pixels and just a slight crop compared to s35.
What you gain is Redcode RAW, and a true "sports finder" with a safe area outside the recorded frame.

Why would anyone want to achieve a s35mm frame? 4K to Redcine should do for any type of work, really! VFX shots to good ol' drama.Originally Posted by zakaree

I would want to shoot a S35mm frame because it's what I'm used to... no loss in DOF, no change in FOV, etc. Shooting 4K using the standard 35mm frame is good enough for now, though.

... so then you just crop if you want to have a 2:35:1 aspect ratio?
im just confused on the relation between resolution and aspect...

When shooting REDCODE 4K, the camera is only utilizing the 35mm portion of the sensor. The S35mm portion is remaining unused. That is to say that the S35mm area [full sensor size] is larger than the 35mm area [which will be used to shoot 4K].
As a result of a different sensor size, the FOV of a given lens will change. It won't change much, but it will change. You could crop that to a different aspect ratio [with 2.35 at the extreme] but you will technically be "throwing out" data with such a move. That doesn't actually bother me... but I'd still love to be shooting 2540p [which is currently impossible without shooting uncompressed RAW].
If the FOV/DOF issues are still unclear, I'll expand later.

ya, you might have too...
im not clear on the aspect ratio. Or if cropping will lower the quality. i understand that 4k is compressed with redcode and it looks fine (from what i saw at the la screening) basically this is all i want.. 1.85:1 or 2:35:1
2k or 4k... the use of nikon lenses and zeiss primes (rented of course), fast motion - 24 frames- slow motion... and i think thats it.. the technical stuff of image sensors and resolution is still just a blur for me.. i get the basics but thats about it.
oh.. and ii want to edit this on my own machine... (not send out to bring online).. i was thinking this is possible with redcode since it will be compressing 4k to 2k right?.. so basically.. shoot 4k redcode (use full 35mm frame) then compressed to 2k for edit... is that about right?

Yeah, right now shooting 4k Redcode RAW seems to be the best and most flexible option. Crop and scale will be easy when converting in RedCine
Editing wise, I think DVCPRO HD 1080p is currently a great option for FCP users, but lets wait and see if Greame et al. has something up their sleeves regarding editing codecs.

Anders,
Good to see a photo of you that doesn't have the face all swirled up... That other avatar of yours was really freaking me out! :D

Yes, went for the natural look this time round :-)
Although I'm still in the IBC 2006 frenzy mode in the Pic...
