OK. I have to eat crow. I admit it. I won't just shoot 4K.

Shooting 2K windowed is a completely valid option.

1. Even windowed from 4K, the 2K sensor portion is larger than 2/3", better DOF characteristics than an F23, HDCAM or Viper.

2. Having 72fps (for now) at this frame size is better than HDCAM-SR 4:4:4, which now shoots 60fps at 1080P.

3. You can use all your 35mm PL mount lenses, except at the wide end due to the focal length factor. You'll need a wide S16 lens or two to cover all the bases.

4. The record time to 8GB CF is over 20 minutes.

5. Pushing the data through the pipeline is much easier.

And best of all, the image looks great.

I still will shoot most of my stuff 4K, but I won't hesitate to shoot 2K windowed if necessary.

Nice. Thanks for the feedback! In your opinion, would intercutting between 4K and windowed 2k slo-mo be too jarring, as far as image quality, texture, etc.?

60p is now officially old hat. ;)
 
What do you mean Jim?
We are not 4K or it liiks better in 2K for now while you are tweeking some more?

So, are you saying that 18mm on the short zoom will not be in focus with 2K mode?

Could someone explain this for us dummies (uh, me...) Is this a back focus issue? I was under the impression that I could always use 35mm glass to shoot 2K windowed (thus capturing the center portion of the full s35 lens)?
 
no, 4k is okay. he once stated that he would always shoot 4k and 4k only. Now he is seeing characteristics of 2k that validate it's use to him.

I think he means that you're going to want something wider than 18mm in 2K windowed mode. When you shoot 2K windowed, it crops the center of the image, so it's not as wide. Having a 10mm or 12mm lens for 2K windowed will probably be very advisable.

Thanks for clarifying Jaime. I was planning on getting a cheap 8mm Peleng for just that purpose. The fisheye distortion is crazy but not too bad in the center of the lens.

depends.. if your scaling down that 4k to 2k and intercutting the 2k you will be able to get buy.. but trying to scale up 2k to 4k isnt gonna look very good.

That's exactly it. In 2K windowed mode, you're seeing 1/4 of the entire 4K image area cropped out of the middle. It has a 2X zooming effect. You will want a wide s16mm lens to handle the wide end of things. an 18mm s35mm lens on the camera would be like a 36mm when shooting in 2K windowed mode.
 
The Canon 10-22mm and Birger will be perfect for most 2K windowed work on the slightly wider side. 10mm is very acceptable wide angle for S16mm coverage.
 
Great news about this 2k...I look at it this way, my clients are happy with my current 720p footage so I can really see this 2k being useful in many scenarios.
 
heh, the efs 10-22... my favorite lens... ever.
 
Cool I'm glad that the features are coming on line. I could not help but think as we were shooting last week with #8 and #13 that It's Cinematography Year Zero.

Banzai !


***** Oops read the answer to this further down the list, Apologies *******

I see many situations that would benefit from using 2k scaled Raw, how's it going with that ? Is it still on the table for the medium near future ?

I love that we have a choice, 2k or 4k! It's funny that 2k is suddenly not good enough :) for some. I know there are cases, but unless it's getting projected, I think 2k is going to look mighty fine on 1080p tvs. I'm way excited to have overcranking on 2k material.
 
Just a reminder, 2k is about 10% more resolution than 1080P... in case you forgot.
