C300: C300 Mark 2: 4K 10 bits 422 VS 2K 12 bits 444 upscaled to 4K

Hi everyone,

What would you use for best quality between 4K 10 bits 422 and 2K 12 bits 444 upscaled to 4K ? Thank you.

I usually shoot 4k if I want to have the ability to crop in in post or if the client requires 4K. I shoot 2k 12 bit in every other scenario. I can do some tests tomorrow and share if you want.

Pretty unscientific I know but I only had a little time to do it. Settings were:

CLog3
F9
ISO 800
180 degree shutter
23.98 fps
5600 kelvin

For the first batch they are totally untouched.

The second batch I adjusted levels and saturation only (not hue) and tried to make all levels of ND match more or less. Within each ND group, the 4K and 2K have the exact same color adjustments.

Let me know if you have any questions.

Thanks for doing this. Would you mind enabling the download function on Vimeo? Curious how this looks on an adobe timeline versus online/compressed.

Thanks again,

Mark
 
Its interesting how the 2K 12bit has so more noticeable noise in the shadows when pulled up. Both the 4K and 2K are noisy, but the 2K has a different color cast and is qualitatively more distracting to me.

Yeah, in general I've noticed that the C300 Mark II does MUCH BETTER at having the ISO pushed up prior to recording rather than gain being added to an underexposed image after the fact.

Not necessarily that surprising but good to know: Always bump the ISO higher while recording rather than hoping to recover in post.

As far as the 2K vs 4K noise, I'm assuming that has something to do with the upscaling? Anyone want to weigh in?
 
I will make a doc soon and I wonder what should be the best between 4K 10 bits and 2K 12 bits. I will make the doc totally independently so I don't have any request from any client but I want to be able to broadcast the film in the most places as possible. I wonder if, for exemple, Netfix would accept HD video upscaled to 4K or if they only wants native 4K. Between 4K and 2K what would you choose? Thank you.

Based on the test I did above, I'd go for the 4K 10-bit. The 4K looks sharper than the 2K upscaled and I don't find gradients and color to be that much more smooth, even when doing basic grading. Shooting 4K however, allows flexibility that 2K doesn't, and flexibility can be important when shooting a documentary (being able to punch in a bit without it looking too soft). Finally, if you want to be able to deliver it to any platform over the next 5 years, you'd probably want to have a 4K version ready, which, again, will be sharper than the 2K upscaled.

This is just my personal opinion! Good luck!
 
I was faced with a similar choice on a documentary in Rwanda. I ended up shooting the interviews and verite in 12bit/2k and all of our B-roll in 4K.
 
Yes, especially helpful with data management. The director found out in post that the 12bit files were much more taxing on his edit systemt than the 10/bit.
 
Hi,

Finally I will shoot in 4K because it's more future-proof and I'm still on Mac Pro 2010 so I need files that are not too taxing like 2K 12 bits seems to be. Thank you very much guys!
